• Running the old and new Vcenters simultaneously on the same San

  We spend VSphere 4.1 to 5.5. We are very weak with only 3 hosts running about 20 comments of the virtual computer on a San.  Our former VM VCenter is always on Win 2003 and I am changing as well.

  So instead of doing an upgrade from 4.1 to 5.5 and convert the former vcenter 4.1, we decided to simply fill out a brand new VSphere 5.5 installation to a new server we have.  We have also installed a Vcenter 5.5 new appliance as well. So, essentially, we have installed two different vcenter, old and new running.  Then, we plan to move hosts esxi 4.1 existing in the new Vcenter device manually.   Then eventually fly over the guests of a host in the new box and then wipe and reload each older host with 5.5

  So I've already finished the first half of this project.  But I have a question.

  During the passage of Windows VCenter 4.1 to the new host esx and VCenter Unit 5.5. I run two VCenter (ver 4.1 and ver 5.5) simultaneously for a short period of a few days.  We're still running on the host 4.1 old and the new vcenter 5.5 running on the new esx host 5.5.

  We will walk a host both the old VCenter and will be added to the new Vcenter 5.5 appliance.  But I'll share my SAN alone of course. If I do this and the two versions of VCenter (old and new) running at the same time and sharing my data SAN even stores at the same time, are there problems with it?  I don't think so, but I'm not sure.

  I installed the first new esxi host and I pointed out to my warehouse of SAN data without any problem. And data warehouses has appeared as they should.  But when I add the new host for the new VCenter, as part of the installation process, it displays all relevant San warehouses.  I thought it was weird to show during the 'Add host' vcenter.  Are there restrictions to running two VERSIONS different VCenter simultaneously on the same data warehouses?

  Thank you.

  HMorris

  You can have multiple instances from running in the same environment vCenter server. What you need to take care of, it's that the ESXi hosts that share the same warehouses not have access to each and other virtual machines (i.e. do not add VMS to multiple hosts). Keep in mind that only VMFS3 data warehouses are available in two versions, do not pass the VMFS data store to VMFS5 when running always hosts v4.1.

  > as part of the installation process, it displays all relevant San warehouses

  That's ok. When you add a host to vCenter Server it will show that all connected, as well as the VMS data warehouses that are stored on this host.

• Problem of SAN disk sharing

  I am trying to share a SAN between ESX 4.0 and a 2008 physical disk server.  The windows Server 2008 has onit netbackup and netbackup must be able to see the same LUNS as the vmware esx so it can back up data through the fiber.  When we present a lun on the esx server and create a data store, then I try to bring back the same LUNS online on the windows 2008 server it will not go online it says device is not ready.  We did a test and present another windows 2008 server, and ESX server logical unit number and I brought the LUN online on the windows 2008 server but then I couldn't do a data store on the ESX Server.  What we lack to be abel to have two servers share the disks?

  Please let meknow if anyone encountered this problem and the fix possible.

  Thank you for your help

  The snapshot for EMC San feature is an additional feature, so that you will have to pay.  You will need to speak with that whether you bought your San to to see if you can get this functionality or if you already have this feature.

• Several groups of PS in the same subnet

  Is there something wrong with having two PS series groups (and, therefore, their members) in the same 24 subnet and the same VLAN?  We have a PS Group in the same place we are moving to another site that already has a PS Group.  We would like to just take advantage of the networking and configuration of VLAN, that we have so I just want to check that it is not a problem to do this.

  Thank you

  Bryan

  Hello Bryan,

  The only limits are the IP addresses available, switch ports available and that the switch can handle the load increases.  Especially if you share the SAN and LAN traffic to the same switch.  Also the link between the switches might need to increase as well.

  There is nothing inherit in the design to prevent it.   In my lab, I have quite a bit on the same subnet.

• User's home drive do not disconnect on logout - El Cap / SAN / SMB

  10.10.5 managed Server 5.1 customers / 10.11.4 Server and the Profile Manager

  We have recently moved to a new SAN.  Our old SAN (CEM) used to go nuts if we have enabled SMB 2 when connecting with our Macs.  We forced protocol SMB 1 on our customers and this stopped file corruption and the SAN to bananas.

  New SAN (ch) supports SMB 3.  Migrate all user data and found that funny permissions files Mac (movies, music, photos, library etc.).  The "Everyone" group was set to 'Deny' and either remove it, or just refresh perms on a folder that has allowed the correct users access.

  When you use SMB 1 on our new SAN, it was slow as dirt, so we have enabled SMB 3.  Much faster.  Our problems are the following:

  1 - when a new user is created, and they connect for the first time, they get their 'Mac' folders created.  They are made with the funny perms that prevent users who register in these files.  We got around this new users by creating a template for folder for them BEFORE opening of session that contains the correct permissions.  Store us existing users running a monster script to strip and update perms.

  2. when a user logs on to a Mac client in network, their network folder does not disconnect properly, leaving open which means if they connect to another machine their Keychain can go nuts.

  Everyone here has experience with Macs and WITHOUT and dubious permissions?

  Roughly permissions must be that the owner can access the files and content, but everyone should be declined. As long as the user creates the folder, they should the registered owner.

  Yes unfortunately network directories have a lot of questions. This is something that I and others have seen as well as various other issues. I have I feel resolved this by putting in place a logouthook script that takes place as his name when the user disconnects, and checks and if necessary disconnects all left to mount the users home directory. Here's my logouthook script.

  #!/bin/bash
  # Kill secd processes left running after user logs out
  killall -9 secinitd
  killall -9 secd
  logger "LogoutHook killed processes"
  # Unmount network home directory share if left mounted after user logs out
  mountpath=`mount | grep /Network | awk '{print $3}'`
  if [ "$mountpath" != "" ]
  then
    umount -f $mountpath
    logger "LogoutHook unmounted network home"
  fi
  # Delete old stuff from /private/var/folders - mainly cache files after user logs out

• UIR corrupted on SMB share

  Hi all

  first of all, can someone tell me if the closed CVI2010. The IUR file is corrupt?

  -It opens fine in CVI as a local file

  -It opens very well as a local file with my executable LoadPanel

  -on a Samba share, I get "could not open the interface... resource file. Suddenly end of file reached.

  -using the LoadPanel I get NO FATAL RUN - TIME ERROR: "l:\dim_v17r5\DimGpio\Diagram.c", line 225, col 18, thread id 0x00000A88: library function error (return value ==-92 [0xffffffa4]). Suddenly end of file reached
  -on Linux, it crashes in LoadPanel with a core dump

  Other (smaller) UIR files work very well in all circumstances. This file is used to run properly. And now I am unable to work because I can not work locally (and the Linux version won't work either).

  This problem related to it but seem is different... Yet the WinXP where I run CVI is in a VirtualBox. The files are on the shared folder of a large SAN, samba for Windows, NFS for the side Linux.

  If you guys don't think that the file is corrupted, and I think that you will not because I checked the checksum of the previous work, then it's a weird interaction Samba/VirtualBox bug.

  Found. My Samba share had reinstated a Vbox share. How, I have no idea. It took me a long time to understand.

• Helps the FS7610 PS Series SAN, 10Gb network design

  Hi, we have currently a square of infrastructure EqualLogic SAN and NAS (2 x PS6510E, FS7500), a stack of two PC8024F 10 GB switches, 2 envelopes chassis m1000e blade with the A1 being a set of switches 1 GB m6220 fabric (fabric A2 a battery of the same thing), the tissue being a pile of m8024k B1 10 GB passes, (fabric B2 a battery of the same thing) and a stack of PC6224 two 1 GB (top of the grid GigE) switches.

  We all have this connected to the 10 GB being its own private network 10.1.0.x SAN network and vlan, nice and isolated from all the rest.  The blades can access the iSCSI shares via their network cards of 10 GB which is all on this network 10.1.0.x.  The NIC 1 GB on the blades are on a public network, and the FS7500 of the customer ports are on this network too via the 6224, so NFS connections are established via the public network to 1 GB.

  We intend to invest in an additional PS Series array to the host to a backup site, for replication.  At the same time, we plan to buy a FS7610 to our main site to take advantage of our 10 GB infrastructure and move the FS7500 existing to our backup site, so we can replicate iSCSI and NAS container volumes.

  That's where we could use some help, because now many things have changed.  Now, the SAN must be on the public network for replication to succeed, AND to take advantage of the connectivity of 10 GB and sharing NFS mount of the FS7610 through 10 Gbit, we need to use network cards 10 Gbit and switches in the network of the client NAS, that are already used for iSCSI traffic (and will in the future be used for connections to SAN vmware hypervisor).  In the FS7610 install and set up the guide, it says

  • Use the switches for network client and for the internal network and the SAN.
  • Use separate subnets for network client and for the internal network and the SAN.

  We can move the SAN and it is a dedicated subnet network and VLAN that is on the public network without problem, but my main concern is to be able to satisfy the recommendations/network configurations required for the FS7610 and avoid the local SAN/NAS traffic through a router to ensure connections of 10 GB.  Advice or tips are appreciated!

  It is the same thing that you are dealing with Linux, but TCP/IP standard routing.   You cannot route private subnets directly on the internet.  We need to create a "Wan".   Do not directly routed on the internet.

  Your WAN will create a private network and a tunnel over the Internet.   OpenVPN is a possible solution.

  A very widespread scenario might be:

  Once you have put WAN in place, on the internet of these routers would be a true internet address (e.g., 62.x.x.x.x) so the two WAN devices can communicate with each other.   They create a VPN tunnel with a new subnet, say 10.3.0.x.

  The WAN router primary side would have a leg on the subnet 10.1.0.x, say with 10.1.0.10 IP address as your default route on the side of EQL SAN 10.1.0.10.

  On the side of the DR this router would have a leg on the 10.2.0.x subnet, say 10.2.0.10.  The default GW on the side DR would be 10.2.0.10.   The router knows how to move packets between networks using the standard range.

  Looks like all you're missing is the "WAN" VPN tunnel between sites.  You want something that will encrypt traffic between the sites anyway.

  Who help me?

• 3rd party such as san replication solution: strategy

  Dear Experts,

  Can you please share some of your ideas.

  Oracle DataGuard comes free with Oracle Enterprise Edition (EE). The only reason why a company could NOT use Oracle DataGuard is because they are not on the ERA and the cost of upgrading to EE just to use DataGuard does not justify the price.

  With 3rd party such as san replication solution. (for example hp3par)

  It is obvious that the all-flash backup can be quick.

  What should be the strategy to have DR site get a few seconds, if the primary site failed for some reason any

  1. daily incremental backup with RMAN. And archive backup runs for every 1 minutes

  2. so that the DR site facing up and running within 60 seconds, it still requires too much time to restore the database on remote site and have archive APPLIED setpoint

  What could be the solution with san replication? RTO = 60 seconds

  Thanks ivw

  Hello

  Great topic, I'll try to summarize all this in a post.

  I have worked with HP EVA for a few years and I must say that I have used many of the features of replication - HP EVA Business Copy (local replication) and HP EVA continues access (remote replication) as well - for the oracle database and other applications as well. Most storage systems use copy-on-write to create two points in time of the LUN (snapshot) image or clone LUN using cow again.

  Of course, like other people, said earlier the replication SAN is block based, in the same way with Dataguard, you have synchronous and asynchronous replication. When your data is written to the data files it usually goes in storage cache and then is pushed down the disc as soon as it will be more efficient, at the same point, replication is pushing data to the Dominican Republic. The same way with Dataguard if you use synchronous replication that you won't get you "speedy return" until the blocks of primary storage has been written for DR storage system.

  I never had problems with replication to be honest. I used a lot of copy of databases of production using local replication. For example if you want to quickly test a patch on the production system, you can create a snapshot that will only increase with the amount of changes you have made. The only concern is nowadays though we use ASM so if your diskgroup names are the same in DEV that the PROD does not work the approach that I mention.

  Regarding remote replication - because you do not have Dataguard more every time you failover to the Dominican Republic to your database will pass by instance recovery!

  Regardless of the type of replication is not the speed but the latency of the network - SAN or Dataguard, you will always have a penalty of a long replication distance. The biggest typical WAN latency factor is the speed of light, via fiber optic cable, which is about 124 miles per millisecond. Based on that you can calculate what would be the round-trip latency time.

  Indeed for many people SE installation choose DBvisit Standby to manage their databases on hold. I did the installation of the couple and it is really simple and works out of the box. However, your RPO depends on how often you switch your redologs and how many times you ship them to the backup site. You must configure dbvisit to spend with each log file (all the 5,10,15 minutes) OR configure archive_lag_target to configure OR use both at the same time. Also, you can store a copy of the archivelogs on a separate location just in case, for example, an NFS share.

  And finally my five cents on RAC on Clusters of extended - be careful with this one. Each of the nodes in the extended database cluster need access to both storage (primary and DR) systems. You must also third location to store a voting quorum disk, usually an NFS share. It is also very important to note that the latency between the nodes is of crucial importance due to global cache activity.

  Kind regards

• SAN disks on 11.1.2.4

  SAN drives I tried one in conjunction with 11.1.2.4?

  We 11.1.2.1 upgrade and have been performed on applications. The performance has been disastrous with calculations has increased x 5 or more. While the same calculations when opposing a local HARD disk works give comparable results between 11.1.2.1 and 11.1.2.4. HE insists that there is something wrong with the app and not SAN. So I was wondering if anyone has tried it and can share parameters.

  So, we ended up buying EMC 8060 SSD based SAN. The performance is now almost 1.5- 2 x better than before.

• To work with a SAN and vMotion virtual servers configuration

  Hi all:

  I apologize in advance if this discussion is too much like another.

  I intend to use the following configuration (not yet deployed) and would appreciate your comments and input:

  2 physical host servers running VMware ESXi

  1 SAN Fiber Channel

  high availability and vMotion

  I just have a few questions:

  (1) then I keep all the VHD on the SAN files?  (I intend to have VHD files separate OS disk and DATA drive for each virtual computer).

  (2) is it recommended that I have all the hard drives the on host computers physical (to run virtual machines or anything else like swap files)?

  (3) how much space I have on the SAN?  I guess too much for the readers of the OS and DATA readers of all virtual machines... it's any additional space recommended for anything?

  (4) everyone would be able to direct me towards guides describing how to set up?

  Sincerely,

  Kahn

  (1) then I keep all the VHD on the SAN files?  (I intend to have VHD files separate OS disk and DATA drive for each virtual computer).

  Yes you can, and just a tip, on VMware world the virtual disk is called VMDK :-)

  (2) is it recommended that I have all the hard drives the on host computers physical (to run virtual machines or anything else like swap files)?

  You can use the same physical host computers without the hard drive, because you can boot from SAN, or use features such as automatic deployment, but it is the facility for the virtual machine, my recommendation is to use disks (volumes) of your San and share this volumes between your hosts to be able to configure High Availability (HA). Without shared storage, you can not HA.

  (3) how much space I have on the SAN?  I guess too much for the readers of the OS and DATA readers of all virtual machines... it's any additional space recommended for anything?

  Space on SAN depends on the size of your virtual machines and little extra space to make room for Exchange and snapshot files.

  (4) everyone would be able to direct me towards guides describing how to set up?

  The documentation will have everything you need: VSphere 6.0 Documentation Center , but if you want some guide step by step and with video/screen, see this one: BackToBasics | Mike Landry...

• Different connetced in a vSphere San

  Hello community,

  Does anyone have configured two different without worms a vSphere by iSCSI?

  I have HP Lefthand connected to my box of vSphere ESXi 5.5. Now, I want to connect DELL SAN 3620i for the same box of ESXi and migrate all data using storage vmotion for new storage.

  I'm confused if ESXi box will work correctly with two different, because you can create a single iSCSI Initiator on ESXi box and need to work with two different iSCSI targets.

  Does anyone have this expirience?

  Thank you

  You will need separate adapters for each subnet Yes vmkernel. They can share links rising/vswitch however.

• Migration of servers to new host and SAN

  Hello

  Current configuration:

  2 x ESXi servers, local storage, share nothing.  License of VMWare Essentials

  New configuration:

  3 x SAN Eqllogic, ESXi servers. Essential Plus VMWare license

  I would like to make the transition to the new configuration with minimal downtime, we have invited a few large (> 1 TB) on one of the servers and I don't want them to be disconnected for more than a few minutes, then a migration cold is out of the question.

  I had a thought that I could put the license key more on the old servers and 1 new servers, set the new SAN on the old servers, use VMWare replication to replicate virtual machines among the old servers to the new server/storage, and then perform a recovery.

  I would then remove this old Vsphere server, add a new server and transfer the license, then perform the same task on the old server to 2nd.

  Once it is finished I remove the old server 2, add the new 3rd server, and move the license.

  Can someone tell me if this is possible, or suggest alternatives?

  Thank you

  Dean.

  Hi Dean,

  Replication (replication vSphere) VMware will be requires downtime when you are recovering from the old host to new host.

  How much time can you afford for downtime?

  The recovery process will turn off the source/protected VM on the current host (VM function how long it would normally take to perform a shutdown comments) and destination/recovery VM will be powered on to a new host (again, depends on VM normally, how long it would take for the operating system and services until then a normal diet on the process).

  vSphere replication requires vSphere Web Client and other requirements, as described here: 5.5 - replication requirements vSphere vSphere Documentation Centre

  You have a vCenter Server?
  What version of ESXi (and vCenter) do you use?

  If you don't have a vCenter Server yet, I suggest you install a vCenter server and add all the current 2 ESXi hosts + 1 new ESXi host.

  From there, you'll have an ESXi 3 host, then you can migrate current ESXi host for new.

  If you are using vSphere 5.1 + you can vMotion, even if the host do not have access to the same storage see this: library of vSphere 5.5 - Migration with vMotion in environments without storage shared

  Its quite simple, if you are using vSphere 5.1 +.

  -Make sure you have vcenter Server 5.1 + with vSphere Web Client

  -Add current hosts + 1 new hosts

  -Make sure the vMotion without requirement for shared storage are filled with VSphere 5.5 Documentation Center - requirements and restrictions for vMotion without Shared Storage

  -Perform vMotion without process Shared Storage of current host to the new host + local storage to SAN EqualLogic - you can start with small VM and VM less critical first if you are not sure.

  -Once all virtual machines have been migrated to the new host + EqualLogic SAN, you can do a maintenance on the current host mode, and then delete the vCenter Server (vSphere licenses will be retrieved)

  -Add the 2 remaining new hosts.

  If you are using vSphere 5.1 prior, you must present the SAN EqualLogic again 1 new host and current 2 hosts.

  Once current hosts can see the EqualLogic SAN, make a Storage vMotion (live migration records) local storage to the EqualLogic.

  For first migration vSphere 5.1, there are 2 ways that I can think of:

  1. with vMotion - without interruption

  There are certain requirements of configuration for vMotion work: Documentation Centre of vSphere 5.5 - Migration with vMotion

  Make sure your classes and new hosts are run in the same processor / EVC mode or matrix, you can check it out here: http://www.vmware.com/resources/compatibility/search.php?deviceCategory=cpu

  If they are on different EVC Mode, you can turn on the CEV on new hosts.

  The steps are:

  S ' ensure that virtual machines are in EqualLogic (you can use Storage vMotion)

  -Perform a vMotion from the current host to new host.

  -Once all virtual machines have been migrated, you can safely do a maintenance on the current host mode and remove the vCenter Server

  -Add the remaining 2 new hosts the vCenter.

  2. without vMotion - requires the interruptions of service commissioning

  It's cold migration but without migration of storage, must be less compared to downtime directly cold immigration to localdisk of shared storage.

  The steps are:

  S ' ensure that virtual machines are in EqualLogic (you can use Storage vMotion)

  -Turn off the virtual machines in the current hosts and migrate (cold) of the host-to-host former New (you can also drag the virtual computer and drop it to the new host).

  -Once all virtual machines have been migrated, you can safely do a maintenance on the current host mode and remove the vCenter Server

  -Add the remaining 2 new hosts the vCenter.
