• 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.

• VMFS LUNS of tape backup,

  Hello

  We have 9 servers to ESX 3.5, a SAN HP EVA 8000 and a proxy server backup of VCB windows 2003 using arcserve

  Is it possible to save a VMFS LUNS set on tape, we can save individual using vcb and it works well, but we need to have a full tape backup VMFS LUNS?

  Is this possible and if so, how? I'm sure I'm missing something obvious?

  You MAY be able to get Replication Solutions Manager to describe the VM snapshots before a SAN snapshot. Or you could use a mirror Clone and save it like that. But the question will read the VMFS. You can add a "helper" ESX Server, but I don't think there's Arcserve software that could be installed in the Central Office.

  The great thing is why you want to do? Is there a problem with VCB? Maybe you could add another VCB proxy if your backup times are achieved. If you go down the path of SAN backups based, make sure that you can recover. more likely, the backup will be consistent down.

• A Windows Server with direct access to a VMFS LUNS can climb the PowerCLI help?

  Hello

  I wonder... a Windows Server that has a direct access to VMFS SAN LUN cannot mount this partition using PowerCLI?

  Has anyone tried this before?

  Thank you

  -virtualhobbit

  No, that goes up the data store you specify (MyDS in the example, but you change this name).

  But the copy of a large VMDK on that provider is not a good idea.

  As you run the script on your PC, it will go on the network.

  As long as you have no functionality to copy at the end, an alternative is to copy the VMDK from the console with the ESXi vmkfstools command.

  See KB1027876.

  The problem is that you must be able to mount the destination locally on the node of ESXi to avoid going on the network.

• ISCSI Lun gone after restart ESXI-home

  Hello

  I have 2 hosts 5.1 ESXI and QNAP 1 for iscsi storage.

  When I restart a host, a logical unit number is gone (other Lun 4 is available).

  I have the following procedure to resolve this problem:

  # esxcfg - volume - m "vmfs_label_name".

  and then refresh data warehouses in my configuration.

  What happens after each reboot the ESXI host.

  As I say... the other 4 LUNs with the same configuration do not have this problem.

  How can I fix?

  THX.

  esxcfg-volume - m "vmfs_label_name".

  Using esxcfg-volume-M

  M must be capital because it would be persistenet to reboot

• No puedo access los los LUN put desde nuevos ESXI

  Hola a todos tengo no problema...

  acabo instalar back nuevos ESXI in e servidores granja ESXI, las areas en los fabric swtches estan well his agredagas al zoneset is activas... put nuevos ESXI al Centre back added virtual sin problemas... pero no veo las MON q tengo his in the SAN... is the he dado en el storage tab not rescan all in storage adapters pero tambien no LUN las Veo , not so to me estoy brincando algun paso...

  Tengo a message in mid ESXI q dice "VMware ESX server has no persistent storage" don't be TR esto tiene algo q ver con mi problema

  Saludos,

  Hello that tal,

  Primero revisar if the fue zonificacion well made o not.

  Luego realize el LUN Masking, weary of básicamente asignar of the LUN's cada host el in storage.  If el storage there is no can "see" a los nuevos to hosting entonces debes revisar el los fabric zoning.

  Por los pasos what indicas's s, veo than hayas hecho el LUN Masking, por lo al hacer el rescan storage of data en los nuevos guests, no podrán 'worm' las LUNs, as no podrán montarlas.

• Material level of VMware vmfs LUNs 4 through 7, issue.

  Hello

  We are currently using esx 4.0 and virtual material all our vm are at version 4. I need to upgrade to version 7 to take advantage of the new api of storage etc.

  My question is, when I've upgrade to version 7 will change the backend disk array vmfs config anyway. Sounds silly and I'm pretty sure that the answer is no. However my production servers and test servers are on the same Lun, so I don't want to upgrade a test version 7 virtual machine and then discover he did change for my LUN vmfs my vm production is also on.

  Thank you

  Craig

  You are right. There is no change in anything other than the VM. No change to VMFS...

• RDM vs. vmfs LUNs

  I am currently restructuring our physical server and SAN environment. I'm not sure what are the benefits to RDM vmdk.

  Example of

  I have a physical SQL Server that has the database stored on a group of RAID 5 on our SAN and it stores its log files on a group of RAID 1 also on the SAN, all very straight forward stuff.

  My question is:

  What is the difference between the creation of a new data store on my SAN with a RAID 5 configuration and having only 1 vmdk which is the D drive on my SQL Server taking into its databases. I have then to create a new RAID 1 data store and organize files of newspapers of SQL servers on it. This configuration would use the same amount of discs and a single server could be access to the LUN.

  I see no difference in this scenario between RDM and 1 VMDK on a LUN.

  Experiences, advice is much appreciated.

  Paul

  RDM is necessary for clusting comments and to accelerate a P2V when data is already on the same SAN.

  In other cases a vmdk is a better choice.

• What expand a VMFS lun beyond 2 TB?

  Hello

  I need some opinions on what happens if you:

  • creates a LUN smaller than 2 TB (say, 1 TB)

  • built a VMFS on him and he put many VM

  • with the virtual machines running, go to the storage array and resizes the logical unit number, making it LARGER than 2 TB

  I know that this is not a smart thing to do and there is no reason to do it, but I want to understand what happens then a strictly tech point of view.

  For what I know about scsi, I guess that the vmfs will continue to work because there is no way to expand it to fill the new size, so he's going to stay within the limit of 2 TB and conntinue to work.

  But is it possible that growth triggers a few changes in the logical unit number so that esx will not longer be able to access the same first to 2, make the unreadable data and cause errors such as corruptions of metadata in the vmfs?

  I need a scsi on this expert opinion!

  Thank you very much for any info and opinions.

  Massi

  And no growth it will not damage your logic unit number. Personally, I don't see why you would want to passing. Creating a secondary LUN and loading with VMFS are much easier.

• Please notify. Thank you

  Hi all

  We have a vCenter existing 4.0 which consists of 3 ESX 4.0 host. (ESX1, ESX2 and ESX3)

  vCenter Server is on Windows server 2003 (64-bit).

  We will get 2 new guests who will be installed ESXi 5.5. (ESX4 and ESX5)

  Ideally, we will have 2 data centers (A and B).

  DataCenterA is to accommodate existing hosts 3

  DataCenterB is to welcome 2 new guests.

  How can I make existing hosts? upgrade or fresh install, this topic I read a lot of discussions, each of which has their own situation and must make their own decision.

  What I've done so far is that freshly installed / configured a new vCenter Server Appliance 5.5 (to save the Windows Server license), it seems to be ready for new guests (honestly, I did before vCSA).

  Action plans:

  DataCenterB:

  When the 2 new hosts (ESX4, ESX5) are ready, they will be added to the DatacenterB which I think that shouldn't be a problem.

  DataCenterA: it is dependent on the upgrade or new installation.

  Any help / ideas would be very appreciated.

  Kind regards

  Hello

  With the new San, this is what you would have in the below:

  DC B - ESXi5.5 + SAN5.5 (new san)

  DC A - ESXi4.x + SAN4.x (former san)

  Support:

  SAN5.5 is also compatible with ESXi4.x

  SAN4.x will be dismantled once the migration is complete, because it is not supported on ESXi 5.5. This means that all virtual machines must be migrated to the new San for this activity complete.

  All virtual machines are currently provided on SAN4.x and it does not yet support 5.5, IMO, here are the options you have:

  Upgrade one of the ESXi hosts to 5.5

  Present SAN5.5 LUNS to the host ESXi 5.5 upgrade

  Storage vMotion virtual machines of SAN4.x o SAN5.5

  Once all of the virtual machines are migrated to the new SAN, the old storage can be taken out of service.

  Otherwise if two storage arrays from the same vendor, you can use the vendor supplied tools to make a copy of SAN4.x block-level at SAN5.5. In the past for VMware data migration missions, I used Storage vMotion, and I must say that there was a big improvement from ESX3.5 to 5.5. However, it depends also on other factors for example, sometimes will and then copy LUN VMFS level is easier.

• How do the backup off-Lan with VCB

  VMware dear Experts,

  We currently have a VCB backup physical server, with the help that we are taking the backup virtual environment, we manage the following scripts

  ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

  CD \program files\vmware\vmware consolidated backup infrastructure

  echo ' # VM1 BACKUP STARTED # "> > C:\Backuplogs\VM1.txt".
  echo "started at % date: ~ 7, 2% date: ~ 4, 2% date: ~ 12, 2%" > > C:\Backuplogs\VM1.txt "

  Ren o:\mnt\BIN\VM1 VM1_ % date: ~ 7, 2% date: ~ 4, 2% date: ~ 12, 2%
  pause

  ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

  192.16.4.11: is a vCenter server ip address

  20.200.20.55: is a VM IP

  o:\mnt\BIN\VM1 is a Destination SAN LUN

  Once we run that batch file backup that happens on the network, now we want the backup must be done at the level of SAN with the help of the VCB server.

  Here's the scenario

  ESX:172.10.10.10

  On this esx, we have a san lun is mapped by a VM1 is stored on the same, we will map the same LUN to VCB server and now the LUN source and destination that is (o:\drive which is already connected to the vcb server) are mapped to the VCB server. Now with the help of the VCB script, we need to take backup of VM1, please help me how to do the same.

  Concerning

  Mr. VMware.

  In a few words, you will need to only present the VMFS LUNS to the server VCB as you said and change the "-m ndb' option '-san m. This should work if the logic unit number is presented correctly.

• VCB 1.5 and iSCSI

  I'm just starting with VCB and hopefully clarification.  The service console for my ESX hosts and my backup server (NetBackup 6.5.4) are located on a network of 10.56.64.x.  Each ESX host sees its LUN through a vSwitch/vmk has nothing but on it and all iSCSI iSCSI are on a dedicated network 10.56.40.x.  No traffic to other networks can hit the 10.56.40.x iSCSI network and vice versa.  Am I ok with this configuration - the VCB proxy would be resident on the NetBackup server and display the LUN through service consoles the ESX host?  Or VCB proxy should he direct iSCSI 10.56.40.x network access as well?

  Thank you

  Your backup server is a physical machine correct?

  If so, then to SAN based backup with VCB, you must add at least 1 network card on your backup server and presents the iSCSI to server storage.  Otherwise, you will eventually make NBD backups via the service console on your ESX host, and these are very slow.

  The other option is to use a helper VM so you can use HotAdd mode for backups.

  Ever option you choose, make sure you read carefully the VCB installation guide.  There are special steps that must be taken on your backup server before presenting the VMFS LUNS on your iSCSI SAN, or you could risk corrupting the VMFS LUNS.

  VCB docs are here http://www.vmware.com/pdf/vsphere4/r40/vsp_vcb_15_u1_admin_guide.pdf

• How to add a LUN VMFS format without formatting? in vSphere 5.1

  Hi people, we need to mount a store of data that was previously seconded.

  Is it supposed to be an option called: EnableResignature or > DisallowSnapshotLun but is not present in vSphere 5.1.

  Can someone has a workaround for this? We just need to set up a data store without formatting!

  We use vSphere 5.1 Ent.Plus Lic.

  Help, please!

  Concerning

  You can always re - mount an individual to a host data store if he is always aware that the data store was just disassembled.

  Options EnableResignature or DisallowSnapshotLun is relevant only if you present a new LUN with the VMFS volume to a host that already has a volume mounted by the same UUID of VMFS (for example a volume snapshot of SAN-side).

  Since few releases ESXi, you don't even have to set the options manually beforehand. It comes when you add the data store in the vSphere Client will ask you what to do, whether it is the will of the volume. Will simply means just assign another name VMFS UUID and the data store, that's all.

  He does not reformat the LUN. So that you can move forward, then up the LUN.

• Emc LUNs move to another host esxi

  We have an ESXi server connected to an emc clariion cx3 - 10 c (iscsi, 1 logical unit number). We will fully ESX and this server needs to be rebuilt to that. I have built a new server esxi and want to keep the virtual machine residing on the lun. Is there a way to communicate the number of logical unit on the new server esxi? I see an option migrate in Navisphere, don't know what it does. I am a rookie!

  You should be able to present the existing LUN as your return VMFS datastore to the new ESXi host by adding the new host of the storage group on the CLARiiON. Then the new server will see the VMFS datastore and as long as (Vswitches) network settings are the same on the new host of ESXi, you can migrate virtual machines to the new host and then dismantle the old host.

• ESXi 5, NTFS, LUN

  Hello

  We have the following situation:

  2 Dell servers running VMWare ESXi5, 1 as backend and 1 as a backup server. Both servers are connected to a system of Raid Dell PowerVault using iSCSI.

  When we arrived a LUN system has already been created on the RAID system using all the available space.

  We want to keep all the virtual machines on this RAID System. Should also be a NTFS file system on the RAID system, who will serve as storage for a Windows file server.

  Can we use this a LUN to store the data store for ESXi 5 and the NTFS file system, or should we create two different LUNS, one for the data store and one for the file system?

  As I am new to VMWare, I don't know how data warehouses are stored on a LUN. Can someone point me to documentation where what is described?

  Thanks in advance

  Stephan.

  Thoughts were to have a server of Windows files as a virtual server, but put the file system managed outside the real virtual server.

  But I don't know if it's a good solution.

  If you really want the Windows file server to have its "own" LUN it is possible, however it is not recommended to VMware to have something other than VMFS on a LUN with a VMware partition on it. If you really want that you create two LUNs, one for VMFS (for all other virtual machines) and a logic unit number which, by a so-called RDM is mapped to Windows virtual server.

  However, as has been mentioned above, the best solution is probably to create a large VMFS LUNS and then keep all the VMs virtual disks, including the Windows file server.
