• VCB and Fiber Channel without

  Hi all

  I have an interesting problem, and I'm curious to know if anyone else has run into it...

  I have a HP DL360 with Windows Server 2003 Enterprise Backup Exec 12.5 and VCB 1.5.  The server is connected to a switch of fiber supporting a Compellent SAN.  VMFS volumes are presented to the DL360 ReadOnly and VCB works perfectly.

  The question is in a reboot of the power of attorney.  The server is located in the Windows startup screen and never loads completely.  If I disconnect the fiber cable and reboot, it does so very well.  I can then reconnect it, scan the LUN and continue on as usual until the next time I restart the server.  I replaced the HBA already, so just try a different material (I have several of these boxes by flying over the building).

  I know that this is not necessarily a problem with VMware, but I thought that maybe someone else ran in this at one point...

  The problem is that your LUN is read-only.  Even if VCB should not be written on these discs, windows wants to be able to have this type of access, while it is coming.  So, it will try to open records in R/W mode, that will fail and causes Windows hang.  So, for a permanent solution, your VCB should have RW access to these LUNs.

• NetBackup, API, MPIO and Fiber Channel Question

  Having a weird drive with a management problem 32-bit Windows 2008 Server NetBackup 7.0.1 - specifically with with LUNS to Windows Server and have see many.  Windows Server has two cards QLE2460, each connected to a separate switch connected to separate controllers that are connected to a CLARiiON.  No PowerPath or multiple paths is used, and I suspect this is the question.

  What is using a similar configuration with PowerPath or other Multipathing up someone?

  Thank you!

  Indeed, the absence of multipathing software activated is the problem.

  As you reinstalled just Vistas, you would have a very limited number of Restore Points!

  Try the system restore.

  If this does not work, and you don't know what you were doing, reinstall it again.

  http://www.howtogeek.com/HOWTO/Windows-Vista/using-Windows-Vista-system-restore/

  Do Safe Mode system restore, if it is impossible to do in Normal Mode.

  Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

  Try a restore of the system once, to choose a Restore Point prior to your problem...

  Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

  See you soon.

• vSphere high availability with no shared storage? And general problems with VMware partner supplier

  
  HA can function without shared storage?

  It may not by the availability of vSphere manual.  However the global VMware partner who sold me on VMware solution said that the shared storage is not required for HA.

  This is the same guy who told me that I would not need to buy Windows Server licenses because everything was included in the package (vSphere Essentials Plus).  Now, I have no Windows license, no shared storage and a customer who will not be happy that we did not include these costs in the citation for this project.

  HA can function without shared storage?

  No.... you need a storage shared for HA.

  This is the same guy who told me that I would not need to buy Windows Server licenses because everything was included in the package (vSphere Essentials Plus).  Now, I have no Windows license, no shared storage and a customer who will not be happy that we did not include these costs in the citation for this project.

  Maybe your partner speak the vCenter Server Appliance that is included on vSphere Essentials Plus and you can use this device to manage your vSphere, ESXi without need a VM of Windows (with Windows license) to install the vCenter server.

• Differences between the ISCSI connections to the storage in vSphere 4.1 and 5.0.

  I'm in trouble of setting up the connections of storage in a new VSphere 5.0 test environment. In our environment VSphere 4.1, it was possible to create a virtual switch add two Broadcom NetXtreme II 5709 NIC. Set assets. IP Hash value as load balancing. (LACP Etherchannel on physical switches) This configuration uses a grain port and a single IP address. Then add our NetApp NFS storage and ISCSI Equillogic storage. In VSphere 5.0, I can't create this same configuration. I have to create separate with separate IP addresses vmkernal ports? The idea was to have redundant connections to the storage and flow of these two NETWORK cards. Possibly adding additional if necessary to the futuer NETWORK cards. Any help with this would be greatly appreciated.

  How can I work around this:

  "VMkernel network adapter must have an active link exactly and no waiting rising to be eligible for the iSCSI HBA connection."

  I can certainly say that the way which allows you to configure the iSCSI Multipathing is incorrect.

  The main idea is to let Native Multipathing Plugin to decide what network path to choose, not the vSwitch.

  At the level of the network layer, you must have 1 VMK by a physical NIC.

  This technique applies as well for vSphere 4.1 and 5.0, but with the 5.0 it is configured easier and more quickly.

  Here's a very brief consequence of steps

  1. get 2 VMK interfaces and assign an IP by each VMK.

  2. set each VMK to use only one physical NETWORK adapter

  3 GB with storage iSCSI software adapter, turn it on and bind your VMKs 2.

  4 connect to your iSCSI storage space

  5 rescan devices, create the VMFS datastore

  6. set the desired load balancing VMFS method or just set up a prior default create new VMFS

• VCB to backup server with HP's Eva and Dell AX4 storage systems

  I have two storage systems connected to a backup server. It is installed on Windows 2003 Server x 64 PowerPath5.2. Windows see each storage only once, so I think that multiple paths to the storage works correctly. Whenever I try to start to browse (or start the backup operation) a VM on HP Eva everythink is ok, but for the VM on AX4 I recive error message:

  Next step would be to check a second time your zoning and lun masking. There could be a conflict with the various mpio drivers between eva and the clariion. I would try to remove all mpio drivers too.

• EtherChannel or fiber channel on 3508?

  When you aggregate several fibers together on G 3508 GBIC, you configure as an etherchannel or fiber channel? I have looked around online for hours, but can not find what it mentioned anywhere.

  Thanks in advance,

  Brian

  EtherChannel (or link aggregate, or whatever you prefer).

  Fibre channel is a data link protocol used in storage networks and a different protocol for ethernet.

• The storage system upgrade

  What risks are there to my ESXi cluster by performing a storage system, level as on a VNX and how serious is the risk (i.e. the temporary loss of connectivity when failover path to the secondary controller, performance degradation, etc.)?  I use Fibre Channel and I need to upgrade the software of OS of OE on my VNX.

  If zoning is configured properly (i.e. of access roads to the SPA and SPB) ESXi, you shouldn't really notice an interruption but simply switch paths to the lun. If you run very high workloads, you should consider to upgrade during off-peak hours (the pre-upgrade check will determine the load of the CPU on the SPs and warn you if it is too high for an upgrade). I just upgraded a few unified of the VNX5400 systems and it took about 3 hours for the upgrade file and block OE.

• vSphere Client Configuration and alarm

  Hello

  I recently started a new job with a company and legacy of the current system and the network.  My knowledge of VMWare is ok, but I'm of course not as great as people in this community.  The issue I'm facing is that there is a constant alarm that needs attention.  We run vSphere Client 4.0.0.  The alarm is one of our stores in DB, and it's "use of the data store on disk.  The alert is set to trigger when 95% of the use of disk data store is reached.  The problem seems to be this VMFS configuration... Here are the analytical capability.  Ability to 99,75 go-go configured 99,55 space free space - 206 MB.

  I contacted the company who originally put this in place, and their response is to ignore the alarm, because it is an efficient use of disk space.  Can someone please comment if this is acceptable or not to "ignore"?  I don't think it's the right way to set up a store of DB, but I just want to check.

  Thank you

  Jay

  Hello and welcome to the forums.

  You certainly don't want to ignore that.  See KB 1003412 for more information.

  Good luck!

• iSCSI and Fibre Channel on the Dell PowerVault MD3000 SAN shaerd with 2 physical servers

  Hi all

  I'm doing new virtualization technologies work in my office for assistance:

  2 x Dell PowerEDGE 2950 III each installed with iSCSI next accessing the SAN controller

  1 x Dell PowerVault MD3000 (10 x 300 GB 15 k rpm SAS)

  The

  VMWare ESXi is installed in an internal USB to load 4 x virtual machines which is

  under SOLARIS (using project, houses, SAMBA file server and)

  Source code repository and compile the source code of the project Build

  Server too.)

  5 x Windows Server 2003 which perform as Apache Tomcat application server.

  And

  I wonder if it has performance benefits in the application of the

  Shared SAN for these two physical server via iSCSI in contrast with

  Fiber Channel.

  I am aware that CF is faster and more expensive, but in this case, I won t run a VM with DB server on it.

  must

  I enter the path to have iSCSI or stick with the given FC

  the SAN runs on 15 k rpm SAS used by 2 ESXi server.

  Please let us know of a reflection regarding this configuration.

  Thank you

  Usually, you take NIC 1 gb connections available on your host and configure them as such.

  2 network cards go to the San, most of the time that it is actually two networks with different subnets.

  1 network card next LAN

  1 network card for the management

  We only use three network cards currently on our guests, 2 for San and the other for management and lan. We use two switches dedicated to dedicated networks dual iSCSI san. This allows to easily add additional hosts in the future.

  You get to decide a bit, but the double san network is pretty much a given. You can do all this of course with the VLANs as well. We use the switches unmanaged yet in our Organization.

  PS: Passing path recommended is to have completely isolated storage of the LAN network / network of the user.

• How to locate the fiber channel SAN disks on the ESX Server

  Hi all

  Please help on this

  How to find and configure the fiber channel SAN disks on the ESX Server

  Concerning

  Vijay

  Assuming that you have configured LUNS on your storage space itself you will need to ensure that the ID in the world of fiber HBA on the host ESX (you can see them registered against fiber HBA under storage adapters, WWID) are configured on the switch of fiber access (read and write).

  In the VI Client connected to your ESX host, select the storage adapters tab and highlight the Fibre HBA. Right-click and select Rescan. If you have correctly configured the SAN and the Fibre switch, then the LUNS now appear under the fiber HBA. Go to storage and select Add storage. Follow the wizard through to add LUNS and VMFS format. Do this for each ESX host that you want to see the LUNS.

• Sierra of MacOS - 50-100GB of storage system?

  Hi all

  I have a Macbook Air from mid-2013 with 120 GB of SSD storage. I have updated my OS sierra and noticed that the 'system' takes up 100 GB of storage! I tried to delete my files, but for some reason, I still has a very high amount of the storage system.

  I decided to clean my computer everything and do a clean install. With the clean install, I have 50 GB of storage of the system. This sounds like a ton of storage used for system to me. Is this typical? I remember that a lot of space in the Yosemite/El Capitan.

  Thanks a lot for your help!

  120 GB SSD storage does not work. What you need, it is 10 times this amount of storage and memory far more to have a working machine. Got a HD big or better get a new machine and couple HDDs connected outside your small computer.
