SAN LUN and ESX growing data warehouses

• ESXi 5.1 and VMFS-3 data warehouses

  We have an existing environment to ESX 3.5 Update 5 7 host and an EMC CX3-10 x iSCSI SAN. We go to decomission 2 ESX hosts and replace them with hardware ESXi 5.1 and recent guests. We realize that we no longer able to manage these hosts ESXi from our Virtual Center 2.5 console, but these two hosts will run a minimum number of virtual machines (Exchange 2010 multirole) that don't use VMotion, DRS and HA.

  Our understanding is that ESX5.1 can see and use VMFS-3 data warehouses. Is it true that, once we plugged the new 5.1 ESXi hosts to our SAN and you can see all the existing LUN that we should be able to stop the virtual machines on two ESX 3.5 hosts and start the virtual machines on the host ESX 5.1 computers?

  Everyone has problems running ESXi 5.1 with VMFS-3 data warehouses?

  Some data warehouses VMFS-3 existing could be improved to VMFS-5 because they are only used by the virtual machines that work on 5.1 ESXi hosts. But some of the data warehouses VMFS-3 existing is not extensible because they are used by the virtual machines running on ESX 3.5 other hosts. In other words, a single virtual machine can have virtual drives running on the VMFS-3 and VMFS-5 warehouses of data at the same time?

  Thank you

  VMFS version isn't a problem. What I am more concerned by the fact that your storage system is not supported by ESXi 5.1.

• How to add SAN LUN in ESX of CLI?

  Hello people,

  I work for a team of engineers to implementation, where our tasks involve the construction of about 15 bunches per month.

  As part of build tasks, we end up consuming more time add the SAN LUN in the ESX servers all running ESX 4.1 through the Victoria Cross.

  I understand that the vmkfstools command could help us create a partition vmfs3 on the LUN, but when I do it asks me to set the partition to 0xfb and I believe that we should use the parted for that utility.

  I can't define it with a single command. My goal is to put these commands in a script to speed up the work.

  

  I'm also not sure if the LUN list that I see in the Terminal Server to ESX Server session is the same as what I see in the VCenter. How can I do?

  
  Comparing the two screenshots, I see an additional LUN of the Terminal Server session

  

  Would appreciate any help in this matter.

  Thanks in advance

  Hello

  Take a look on the link below

  http://www.virtu-al.NET/2009/08/28/PowerCLI-mass-provision-datastores/

  And if you work in a team of engineers, I recommend to familiarize themselves with PowerCLI, tool very powerful

  BTW, I remember if you would vmkfstool used for the creation of VMFS, data warehouses will be not aligned LUN pieces that could lead to a deterioration of storage I/O performance

• Change the name of files and folders in data warehouses

  Is it safe while a virtual machine is running to change the name of the VMDK files and folders in a data store?

  I discovered that a VMS VMDK files have a different name for the virtual machine itself, then someone changed the name of the virtual machine after you have created the records

  I had to do it a few times, will try to document the process that I follow.  If you have many warehouses of data, then make a note of what data store, the machine is in.  The next step is to unregister the virtual machine from vCenter / ESXi

  Then, you need to enable SSH on your ESXi host

  Use Putty or something similar for you connect to the ESXi host

  Run the following commands (in italics)

  cd vmfs/volumes / that is, if the data store that contains the virtual computer is named datastore1 then you would run cd/vmfs/volumes/datastore1

  Then run ls to verify that the virtual machine file is here

  Rename the folder by using mv

  Change to the folder with cd

  Rename the nvram, vmsd, vmx and running again is to say the mv

  MV oldname.nvram newname.nvram

  MV oldname.vmsd newname.vmsd

  MV oldname.vmx newname.vmx
  

  MV 1234.hlog - oldname newname - 1234.hlog

  Rename the vmdk with vmkfstools EI oldname.vmdk newname.vmdk

  Edit the vmx with vi newname.vmx

  Replace references to oldname to newname in this file

  Register the virtual machine with the ESXi server and it should be OK

• Disk space reduced after deleting and creating SATA data warehouses

  I was experimenting with measurement feature multiple with a host ESXi 5.0 (build 515841), which has two 2 TB SATA drives connected to the motherboard SATA controller. For the test, the first hard drive was installed with a VMFS5 data store and the second disc was added as an additional measure. The ability to store data went up 3.62 to as expected (individual drives show up 1.81 TB in VMware). After the test, I deleted the data store to configure the drives as of separate data warehouses. The second disc correctly displays a 1.81 TB of available space, but the first drive shows only a maximum of 256 GB of available space. The structure of the disc shown before creating the data store on the first hard disk shows 1.81 TB of free space. Additional free space can be recovered without having to reinstall ESXi? Thank you.

  I didn't not experiment a lot with VMFS-5 me yet, but I have had a few discussions with other users. What they say, you can be able to increate the VMFS partition of size (in stages) by using partedUtil, and then run vmkfstools to cultivate the datatore. See for example Re: cannot increase the capacity of VMFS 5.54 data store

  With your layout of the partition, it would be s.th. as these two commands:

  partedUtil resize "/vmfs/devices/disks/vml.01000000002020202020204d4e313232304633304d41553544486974616368" 3 10229760 3907029167
  vmkfstools --growfs "/vmfs/devices/disks/vml.01000000002020202020204d4e313232304633304d41553544486974616368:3" "/vmfs/devices/disks/vml.01000000002020202020204d4e313232304633304d41553544486974616368:3"

• KB 1008130: Failure of VMware ESX and ESXi 3.5 U3 of e/s on the queue (s) SAN LUNs and LUN is blocked indefinitely

  Does anyone have more information about the current alert to support "all of you who have upgraded, or are planning to upgrade worms, ESX 3.5 Update 3 or ESXi 3.5 Update 3, please read the Article 1008130"? ".

  Ko describes possible symptoms and identifies the affected ESX 3.5 U3 version, but the resolution is a bit vague. I understand they are working on a fix but,

  1. Is it related to a specific build of U3?

  2. Are there precautions that we can take to minimize the risk?

  3. What is the scope? My hypothesis is not very because 3.5 U3 has been a while and I know this support alert is recent.

  4. Anyone experence this first hand... at what level... There you said what though it is indicated in the KB?

  I didn't have symptoms on the hosts I've 3.5 U3, but I planned improvements to several hosts this weekend and would like to know if I have to go through the painful process to cancel or reschedule.

  3.5 has the robin load balancing experimental, but who would not count as a path failover (I don't think).

  You can force the LUN through a certain path, it might take a few attempts on Lun busy because the load balancing cannot be changed when an INTERNATIONAL organization is pending (this is how works iCSSI HW).  When you fail switches that nevertheless taken into account as a path failover, so I don't know how that comes in re: this issue when no LUN use this path.

  For more security perhaps you put a hold:

  • DRS

  • SSH logins

  • Backups

  • Restorations

  • Clones

  • on/off switch

  • etc, etc, etc.

  While the path are past failovers.

  If a path fails on a single host, I would be surprised if it affects other hosts.  Guests will book the file on the VMFS file system when they need to update the metadata or write data, I think that should continue its work.  However, if you take a switch, you may have failures in path on all of your guests...

• Best Senario distributed virtual machine between SAN LUNS and replication fail over Senario

  What the best best Senario for the installation of virtual machines on Big LUN or each VM on LUNS dedicated:

  We planninig to implement 70 virtual machines on Esx 3.5 servers with replication LUN usisng CA of HP 7.

  using 4 Big 800 GB data store on SAN RAID 5 Lun (each LUN will be contains 16 VMS)? or each VM will be deployed in separate small LUN 50 GB data store on SAN, RAID 5 and that this effect on the failure during the procedure on the DR Site if we choose BIG LUNs, also if this virtual machine includes 3 disks (store them on each disk on the different data store or the same data store)

  Thank you

  Remember that the virtual machine is a set of files and these files directly in your data store.  If you have a large store of data with multiple virtual machines, you must replicate the full data on the alternative site store in order to get to that data.  You can't really use greater SAN replication for just the simple vm in a data store.  SAN replication is not really aware of what is stored on it, she replied just blocks he knows.  You can copy the vm files individually as well, but it's more than a copy and not replication.  Otherwise, if you are concerned about vs some other vm, then using a small LUN would work better for you, or warehouses of data at multiple levels allows you to replicate the vm that are important to you and put the rest in a larger data store.

  FCIP/FC/IP doesn't really matter.  Until a table can talk to each other, you're fine.  Our secondary site is hundreds of miles away, and replicate us very well during the period of INQUIRY, from one table to the other.

  Yes, without SRM, you will need to manually register a virtual machine at the time, or write a script to work through all the.

• LUN and ESX Server - basic knowledge

  Hello...

  I'm trying to clarify the relationship of this LUN game in the Infrastructure of VI:

  (1) is it true that you can have 1 VMFS volume associated with ESX Server at a given time?   Or can we have multiple VMFS volumes running on all different LUN associated with the same ESX Server?

  (2) I know that you have have 'shared storage' between the ESX servers in a cluster of vmotion, but the fact that "the shared storage" refers to

  (a) the same VMFS volume (no matter how much LUN spans the VMFS volume) or

  (b) or can it be multiple different VMFS volumes (b/c multiple VMFS volumes can be associated to an ESX Server at a given time)

  (3) If you can have multiple VMFS volumes related to 1 ESX Server, make the virtual machine in a cluster of vmotion, they all live in the same VMFS volume?

  Thank you!

  Also remember that a VMFS data store cannot be greater than 2 TB.

  Also consider what would happen if an administrator has accidentally deleted a LUN

  VMware also creates SCSI reservations on a LUN basis whenever it creates a new virtual machine among other tasks. If these become too high, the logic unit number is locked significantly reducing the performance of the disk. Separation between the LUN, will help

• Export and import in Data warehouse

  Hello
  I built a warehouse project data with a few dimensions and a cube on a server machine, say server1. Now I have another server computer on which I want to develop this project for bulk production.
  I want to import all the developments of server1 to new server machine, say server2, to save my time. I exported the data to the server server1 using the export feature and import the same file to server2 by using the import function. My question is...
  
  Is it possible to use all the imported objects like cube, dimension, maps, tables and sequences in the same way to server2 that I used to server1. If yes then what are the necessary settings, I did. ??? because imported ratings are not able to deploy in the new machine to server2 of various errors specific location not valid and not valid errors for mapping and the dimensions of the table.

• Question about Lab Manager and ESX Resource Pools

  Hello world

  I was wondering if I can get feedback from some of the members of the community.  We used Lab Manager very strongly in our support organizations and it has proved to be a valuable tool.  Recently, we collaborated with the Department of technical training and started hosting online seminars and classes for them using Lab Manager.  Last week we had a fairly large class of users (approx. 45), each duty deploy 2 rather Beefy VMs that were very intensive resources (Jboss, SQL, Mail to name a few).  My colleague and I went through a lot of trials and planning to ensure that our infrastructure can handle the load while allowing our users to date at the same speed and reliability, so that they are used.

  Our Lab Manager ESX server pools made up of the following:

  5 HP DL380 G5 servers with 2 x Quad Core 2.8 GHZ processors (8 cores each) with 32 GB of RAM each

  2 HP DL580 G5 servers with 4 x Quad Core 2.8 GHZ processors (16 cores each) with 128 GB of RAM each

  When the class is running and everyone has made their 2 machines, we noticed for some reason, he was all on ESX2 and 3 deployment (380 s).  Then came the ESX alarms, use of 90% of memory, then more than 100% bringing the disk page.  The CPU usage was at a all time high.

  I look at the 2 580 s and there are about 4 virtual machines deployed on them.

  So my question is...

  How does he know where to launch a Virtual Lab Manager machine?  There's no sense 2 servers have been brought to the red zone, and almost overloaded when the 2 most powerful servers in my farm are nearly dormant.  I noticed sometimes in the past, but not this bad.  Normally, we have about 45-50 computers deployed at some point and it seems to spread them out properly.

  This group of training has access to the same LUN and ESX server with Betclick as any other organization that we have.

  We have decided hosting several sessions of training may be greater than this one and would like to know that the virtual machines will be distributed properly.

  I would like to know your opinion on this

  First to answer your question, then make guess what happens.

  As indicated in response Ilya, LM distributed VMs differently with active DRS resource pools and pools of resources without active DRS.

  LM place VMs when the DRS is not used.

  When DRS is used, we use the DRS admission control to select the host to place virtual machines.

  DRS is turned off, LM uses its own placement routine:

  For each virtual machine, LM filter all managed servers that cannot run the virtual machine. A complete list of patterns are:

  • The managed server has not enough memory or quota for virtual machine to run the virtual machine.

  • The host is not connected to the data store that is the virtual machine.

  • The virtual machine has active state (suspended) and the CPU of the server managed by the waking state has been captured is not compatible with the managed server currently considered.

  • The virtual machine has been a guest on 64-bit and the managed server is not 64-bit capable.

  • The virtual machine has more processors than the managed server.

  • The managed server is not accessible or is set to "prohibit deployments." Not reachable may mean that the lm-agent or its not to ping queries is not answer (this is visible in the list of managed server page).

  Once we have the complete list of eligible servers, we place the virtual machines on the host including the smallest (MemoryReservation % + CPUReservation %). By default, we reserve not CPU on LM VMs, this internship will be largely due to the memory on the host computers if you have not changed the settings of reservation of CPU on your virtual machines.

  For closed deploy to the PF3, force us all virtual machines to go on the same host, so if any virtual machines have any special data store / CPU type specification, all virtual machines is forced to go on this host. If there are conflicting requirements between different virtual machines in the same configuration, deployment will fail. Closed VMs also have another condition to check that is rarely achieved in practice: number of closed networks available on the managed server. By default, this is 20 and you will need more than 20 different configurations closed running on a managed server before you who will strike.  (LM4 allows Cross fencing host, so this does not apply in LM4).

  To make a guess blind because of your distribution problem - if you use the saved state and fencing, it's probably the type of processor.  Processor type can be checked on the host properties page.

  If you not are not I would check that the images can deploy on the 580 s by disabling the 380s and trying to deploy them.

  If you use DRS (which you're not), it could be due to deployment of virtual machines too fast for the algorithm of control for the entrance of VC.  An easy solution for this is to extinguish the DRS on the cluster manager of laboratory.

  We tested load internal repeatedly, the product QA in different laboratories, we run (LM has been used in VMworld Labs for the past couple years and internal systems of training and demonstration for our Organization implemented SE), so no need to worry about this.  I assure you that the first 'real' performance problem you will encounter will be almost certainly due to an overload of your storage array (too many IOPS / s)... and for that you have to distribute content in data warehouses and use techniques of creating paths to balance the load.

  Kind regards

• Clone VM runs on several data warehouses

  Hi all

  I have a virtual machine that spans 2 data warehouses and I don't know how it happened like this:

  I cloned a VM from a template.  The model is in my store of data VOL3.

  In the summary for my VM tab, it shows that it is connected to and VOL2 VOL3 data warehouses.  When I sail both VOL2 VOL3 data warehouses, I see all the files associated with the virtual machine on VOL3, so I do not know why the VIC is reported as connected to VOL3?  It has only 1 drive, and who connects to a single vmdk on VOL2

  Some notes when I cloned the virtual machine template, I forgot that I had the CD connected to a .iso on the VOL3, maybe that's the question?  I unplugged the virtualCD, but no change?  It doesn't seem to be hurt anything at the moment, but I guess it could complicate things on the road.

  Thank you

  Chad

  I think that the reason that you see your vm split into several data stores is the .iso file, presented during the configuration of the virtual machine. Instead of unplugging the drive (which has the .iso file) change the cd configuration to use a client device.

  I hope this helps.

• ESX host managed by VirtualCenter servers all see the same SAN LUNS / data warehouses

  Scenario of

  I have two separate deployments of VirtualCenter (in the same physical location) VCA and VCB with each deployment management 5 x ESX hosts (10 in total).

  All 10 hosts are allowed to look at the same SAN LUNS / data warehouses?

  Or I have to isolate five VCA hosts and five guests to their own SAN LUNS VCB / data warehouses?

  Basically, we have our direct environment and we are on the beta program for VI4.

  I want to turn off a virtual machine in the direct environment and then pull it out of the inventory.

  Then I want to go the VI4 Beta and browse the data store and add this virtual machine to inventory.

  These two environments may see the same LUNS / data warehouses.

  I did and it works however I want to make sure that it is an approved practice.

  You can do that normally without any problems. Even if the virtual machine is in a different datacenter inventory and there Powred-Off. You can map the logic unit number on the VI4 and add to the inventory of the VI4 another host.

  Recently, I did this practice to migrate from host with virtual machines in a different subnet to the host who knows the same setting SAN LUN in the other subnet.
