• Add VNX LUN for ESX

  I am trying to add VNX LUN 4 to our production 4.0\ESXi ESX VMware environment 5.  Each logic unit number is 1024 GB - we want two 2 TB VMFS3 data warehouses.  In vCenter, I created the first 1024 GB data store.  When

  try to add a measure for the 2nd LUN 1024 GB I noticed that the # display in vCenter LUN was not the same thing as what shows the VNX.  I have published a couple of new analysis all orders, but still see the same

  difference in the numbering of the logical unit number.  Should is this normal - I worry?  THX.

  There may be an incompatibility between the ESXi and storage you... have you checked the IVNSJ for identification?

  You can check the host lun id in your storage space?

  You should think about creating a LUN 2 x 2 TB (and 2 data without extensions stores) instead of 4 x 1 TB LUN (and 2 warehouses of data with 2 Extensions)

• 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

• Renowned guest VM in unregistered VC, the directory/files on LUNS not eponymous.  Impossible to find.

  Hi all

  I'm trying to find a guest I was trying to move to our new VC and 3.5 environment.  I have unregistered the old VC and went to re-register is another from the LUN, but it seems that the files were named something completely different.  Is there anyway to search for an IP address or something like that to find which machine it is?

  Thank you.

  You can actually search all files .vmx under a certain VMFS volume or all to search for your VM specific and as noted, if you have something specific like VM name, MAC, etc., you will be able to search for the string with the .vmx file.

  Here are two examples:

  (1) you know the MAC

  [root@everest ~]# for VM in $(find /vmfs/volumes/everest-local-storage/ -iname *.vmx); do grep -i "00:50:56:99:52:7b" "${VM}"; if [ $? -eq 0 ]; then echo "${VM}";fi; done
  
  ethernet2.generatedAddress = "00:50:56:99:52:7b"
  /vmfs/volumes/everest-local-storage/thegeneral/thegeneral.vmx
  

  (2) you know the VM name

  [root@everest ~]# for VM in $(find /vmfs/volumes/ -iname *.vmx); do grep -i "thegeneral" "${VM}"; if [ $? -eq 0 ]; then echo "${VM}";fi; done
  
  nvram = "thegeneral.nvram"
  displayName = "thegeneral"
  extendedConfigFile = "thegeneral.vmxf"
  scsi0:0.fileName = "thegeneral.vmdk"
  /vmfs/volumes/49a096cf-9f0ae95f-f80a-001f29c7b048/thegeneral/thegeneral.vmx
  

  Do not forget to provide the VMFS volume in the param to find or update the name of your virtual machine or whatever it is that is stored in the .vmx that you can key off of specifically.

• A copy of the Lun in ESX 3.5

  Hi all

  Be friendly with me so here is my first message/question

  In my business, we would like to increase the size of the LUN as we are in a lack of space. We decided to do a copy-Lun to keep all the VM and reattached the lun/storage at the existing ESX (we did not want to manually copy all VM the former LUN to the new...)

  Admin doing storage copy (a test lun with 1-2 test VM on it...) then allowed us on our ESX, the function of "enablesignature". Rescan us the storage card (the new lun appeared...) then we have put back the storage on our ESX Server... BUT recreate the storage has asked us to "reformat" the vmfs partition (and we "lost" all VM inside...)  : 0.

  My question (and I know for sure someone already dealt with that...)...:

  How can we attach a copy of the old one (with VM already on it) to our ESX Server without losing all the data on it? I know that we could create an empty storage and move all the VMS from the old to the new... But because of my business processes, we have only one night to do and not enough time to move all THE VMS 'manually '...

  I forgot something? I did something wrong? After several attempts, same results: we've lost any datasbecause ESX that we were asked to formatt the new attached storage...

  Thanks in advance and waiting for your genius...

  If the logic unit number are the same (because of a copy of low-level storage) your duty as a clone/snapshot (cause disk UUID is identical).

  You must use the DisallowSnapshotLUN = 0 option.

• Sizing of RAW LUN - same philosophy as sizing VMFS LUNS? -esx 3.5

  General consensus seems to be THAT VMFS LUNS presented to ESX should be in the neighborhood of 400-600 GB (approval of application needs should also be considered).  My question is simple: this same philosophy should be applied to LUNS presented to the guests, RAW, especially when I think to create this LUN RAW file server and user directories for fewer than 100 users... or not elsewhere?

  No, the same rules don't apply. You must apply rules that are relevant for the application that you deploy on these LUNs, subject of course to the limit of 2 TB of ESX.

• SAN LUN and ESX growing data warehouses

  I know it's more a question of SAN as a matter of VM, but it is also related to the virtual machines.

  I don't know much about the configuration of a San, first. Laughing out loud

  My question is this...

  I have a SAN FAST600 who has a number of derined LUNS which are no longer in use.

  I want to do is blast them away and then grow my VM LUN so I have a great store of VM data.

  My boss told me that we cannot expand a LUN when it has been set, is it true?

  If you are using vSphere/ESX4, you can grow a VMFS after push you your underlying logic unit number.  You couldn't do this before with earlier versions of ESX.

• 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

• Good 'size' of 2 TB LUN for ESX

  I have the need (on occasion) to provide a virtual machine with a 2 to VMDK.  To do this, I need of course a 2 TB LUNS with a VMFS on that.

  My question is, what it the right size in GB I should introduce to ESX to ensure that ESX (a) we'll see OK and (b) I can only close to 2 TB VMDK possible?

  We have managed to get a unit logic 2048 GB (real 2 TB) visible to ESX number, but had to format it to the command line that the VI Client didn't like it.

  Any suggestion is appreciated.

  See you soon,.

  Doug.

  The maximum size of the LUN is actually 2 TB - 512 bytes - this is due to a limitation of 32-bit and fresh address generals for VMFS accounting.

  You will definitely want to read this article.

  http://virtualgeek.typepad.com/virtual_geek/2009/06/vSphere-and-2TB-LUNs-changes-from-vi3x.html

  It applies to vSphere, but good information, unless you want to mess with your storage during a space upgrade.

• Masking the LUNS in ESX

  OK, I want to use the option in advanced settings VIC to the LUN masking.  I have 2 HBAs on ESX host, vmhba0 and vmhba1 my computer.  I want to mask LUN 3-9 on my SAN.  Thus, in the field mask LUNS, I enter this:

  vmhba0:0:3 - 9; vmhba1:0:3 - 9

  Is this enough?

  However, in my frame of VIC storage adapters, I have 2 target SCSI - I also have to add:

  vmhba0:1:3 - 9; vmhba1:1:3 - 9

  ?

  Thank you very much, I want to just make sure I have all the access roads to the non - ESX LUN masked, in order to avoid future problems of data

• Game of series lun on ESX with the series seen on UI Compellent

  Hello

  I have a table compellent and I trimmed a volume (lun) to expose him to ESXi host.

  On the ESXi host, the serial number of logical unit number I see is:

  6000 D 310005267000000000000000017

  However,.

  UI compellent himself the series lun is shown as "00005267-00000017'.

  While I'm writing powershell scripts that work only with the lun series seen on the user interface, I'm trying to understand how to convert the longest series in the shortest on.

  Any help would be greatly appreciated!

  Response of the developer

  ---

  OK, you get the hexagon series on the side of ESXi, you just need to match to DeviceID rather than the side series Compellent.

  $a = "6000 d 310005267000000000000000017"

  # Connect to the table

  $SCConnect = get-SCConnection - Hostname $array - user $user - pass $pw

  # Get the lun

  $vol = get-scvolume | Where {$_.} DeviceID - eq $a}

  This way you won't have to go through all the transformations and hassle; It should be clean.

• Converter 5 not ESX ESX?

  I'm under Converter Standalone 5.0.0 build 470252.  I have an ESX5 single server with a Windows Server 2003 virtual computer.  I try to convert the virtual of ESX5 machine right on the same server of ESX5.  So I'm duplicating / copying just the VM to a differnet name.  Is this possible?  When I try it fails Converter 1% with "FAILURE: an error occurred during conversion: operation expererienced a network error.  The network is fine.

  Any ideas?  Is this supposed to be possible?

  It's really strange. Certainly, the log shows errors on the network. It's a problem of the ESX host or... I don't know, a network problem which appears from time to time. A couple of wild guesses

• Not supported. of static vNIC to the Palo and Vic CNAs for ESX 5

  Hello

  I looked everywere see that clearly described. Most of the sources list only the no. dynamic vNIC taken in charge. Then I found a document describing the no. adapters for static and dynamic types for some operating systems and ESX 4. But not ESX 5. Someone at - it a CISCO document describing this? I think documentation is vey vague about that.

  If no doc, tdll just me, please... M81kr and CIV

  The calculation as Abi said is based on the number of uplinks recognized.

  The calculation is [15 * (number of links recognized IOM)]-2.

  1 uplink [15 * 1] = - 2 = 13 vNIC/vHBAs

  Uplink 2 = 15 * 2] - 2 = 28 vNIC/vHBAs

  4 uplink = [15 * 4] - 2 = 56 vNIC/vHBAs
