• How LUNS presented to an ESX host

  Dear team,

  How to confirm weather LUN is presented to an ESX host?

  We asked our team to SAN map a 900 GB LUN to one of the esx host, these people have done enough for their purpose (e.g. zoning part etc.) and confirm the same thing for us. We rescan the HBA, still, we are not able to see the same thing. SAN team asked us to reboot and check, but it's prodcurion esx box we will not be able to restart, so I want to confirm end VMware, is it possible to confirm weather esx is able to perceive the lun or the requested LUN is delivered correctly to an esx host, needs your help to understand this issue.

  Mr. VMware

  If you need create a vmfs on this lun data store, then you can simply follow the add storage wizard via - see this link for more information/screenshots: http://www.vmadmin.co.uk/vmware/35-esxserver/109-esxvmfsdatastore

• Maximum number of hosts mapped to a single LUN ESX

  I have a TB 1.9 LUN presented to an IBM SVC to several groups of ESX/ESXi include versions 3.5 (ESX), 4.1 (ESXi) and 5.0 (ESXi).  I read 3.5 has a host LUN '' recommended '' limit 32.

  I'm looking for more details on this issue.  This applies only the number of 3.5 hosts who can see the data store or all combined ESX hosts.  And why is it recommended to vs a strict limit?  We are trying to implement a logic unit number mapped to ESX host clusters as possible in order to support a mass migration to a new environment.

  I'm pretty new to VMWare world so please excuse me if I'm not clear on what I ask, or do not include any other relevant information.

  I don't think it's a contradiction at all.

  It is said that a given host can have up to 256 LUNS.  A volume given (VMFS) are accessible by up to 64 hosts.

  They are 2 completely different scenarios.

• Get the LUN of the ESX host Info

  Hello:

  Is there a way to extract the info from the ESX host LUN?  I need (s) Lun sees number/ID to match the storage admin ID...

  Thank you very much!

  Of course, the easiest way is this

  $report = foreach($esx in Get-VMHost){
      foreach($hbaKey in ($esx.Extensiondata.Config.StorageDevice.ScsiTopology.Adapter | where {$_.Adapter -like "*FibreChannelHba*"})){
          if($hbaKey.Target){
              foreach($tgtKey in $hbaKey.Target){
                  foreach($lunKey in $tgtKey.Lun){
                      $hba = $esx.Extensiondata.Config.StorageDevice.HostBusAdapter | where {$_.Key -eq $hbaKey.Adapter}
                      $lun = $esx.Extensiondata.Config.StorageDevice.ScsiLun | where {$_.Key -eq $lunKey.ScsiLun}
                      Select-Object -InputObject $lun -Property @{N="Host";E={$esx.Name}},

• Make a single LUN can be used by multiple ESX hosts

  Is it possible for a single LUN to be made usable by multiple ESX hosts at the same time?  For example, if you have an image or used by a vSphere environment requiring other vSphere environments in the data center access, you can put the image on a storage place where completely separate ESX hosts vSphere environments completely separate can see the same lun and clone the image or necessary?

  If the logic unit number is locked by accessed by an ESX host will be lock expires when the ESX host is not an another ESX host in another environment vSphere allowing access to the logical unit number, or is the lock, as it is usable by a single ESX host, until the storage is reconfigured to make it usable by a different host?

  Is there a better solution to this scenario?

  Thank you

  You can deploy both at the same time.  Locking occurs only for changes to metadata and only for the shooting of subsecond.  It is not required for the entire deployment process.

• Presentation of ID host ESX host LUN to the VCB Proxy Server

  I have a typical scenario where I have 3 ESX servers with 3 x 800 GB LUNS in a storage group separate on a CX 310 SAN box. The host LUN., of these 3 LUN Ids are 0, 1 and 2.

  I have a specific host that starts from SAN, from the same box of CX 310 SAN. At this point of time, I have no choice to use this server as a Server Proxy VCB. As far as my knowledge goes, LUNS of the ESX servers must be made visible to VCB Proxy Server, as they are presented to the ESX servers.

  My question here is, as the designated Proxy VCB server is booting from the SAN, he already has a host LUN 0 to Id the logic unit number this is the start of. The Id to host ONE of the first 800 GB LUN in the ESX Server storage group is also Host Id 0. Now, if I try to make the LUNS in storage group visible on the VCB Proxy Server ESX, is there not a shock of the VCB Proxy 0 host Id and Id host ESX Lun 0? I'm confused, I don't have a test envirinment where I could try this before I could actually go forward with any solution.

  My intention is to perform a backup outside LAN of the VMDK.

  Any help is that this respect is very much appreciated. Thanks in advance.

  (1) Yes, you can have different host for VCB then for your ESX host LUN ID

  (2) Yes, you can use the identifiers of naa, it will automatically use the identifiers of naa, no need to configure anything at all.

• 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.

• Adding data to the ESX host store

  Hi all

  We are automating the process of adding data to the esx host store. We have all the necessary inputs as a host, Cluster, data center, data store name, store (VMFS) Pat data.

  Do we have the cmdlets to get the result? What is the data store should be added after the configuration of the network?

  We need confirm that the data store must be there in vcenter/Cluster?

  Please help explain the process.

  Thanks and greetings

  If the LUNS on which these data warehouses are defined are zoned and correctly configured as a shared, they become automatically visible on the ESXi node.

  Do you see the LUN on different nodes of ESXi under storage adapters?

• Virtualize vCenter and patching ESX hosts

  I have a host two cluster HA with VSphere Essentials Plus, so no vMotion. (I know... good budget restrictions). It's a whole new infrastructure, so I only have a VM... my vCenter server running on host 1 (config) supported in a small size like mine environment

  I use VUM patch my ESX host that requires that the guests of had no VM and be in maintenance mode.

  The problem: How can I migrate my virtual vCenter server to my other host in order to set the host mode of maintenance and patch 1 (requires a vCenter runs).

  My thought: two guests can see the LUNS for the vCenter server. I think I can go into host 1, power off the virtual machine and then remove from the inventory. Then, I'm going to host 2, browse the store of data LUN and ADD it to its inventory. Is this correct? If so, what file in the data store can I connect to the host (vmx, vmdk, etc.)

  Thank you.

  Yes, it will work, but you will need to attach the base to a host at a time line.  You would add to inventory the .vmx

  Or use the command line

• ESX host, as well as the NFS server?

  Hi all and thanks in advance for any help.

  I want to know if it is possible to turn essential a LUN on a host in a NFS for another host.

  The vmkernel will allow me to share a hdd connected locally on a host to another host?

  For example.  ESX1 has a 1 TB drive, ESX 2 boasts a record of 400GO.  I want to share the drive between machines as data warehouses.

  The hosts are on the same domain and a fairly typical storage facility.

  I want to leave the VI client manage sharing, but I need a mounting point for training and one for access to hosts.

  Setup NFS on both ESX hosts will cause problems?

  Thanks in advance, once again.

  I really need to know if I can just use NFS on each ESX and run it at the same time as VMware.

  The short answer is no.  ESX was not designed to be an NFS server, should not be.  Thus, there MAY be servers NFS that will work, but they have compiled and built on the ESX host, which is beyond the scope of this thread, so let's say no. NFS on ESX host.

• How to balance IO SAN controller between my ESX host?

  Hello good community.

  Question about SAN controller i/o balancing between my ESX hosts.

  I've identified the controller A and B controller on my SAN, HP EVA 6100.

  The controller has 50001FE1 500E1208

  Controller B 50001FE1 500E120C

  But when I go to "Storage adapters", then "Manage paths" by vmhba and I'm lost.  Policy of LB is fixed.    Then I see:

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 * status: active, preferred

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d

  If the first two on my controllers, don't know about the bottom two WWWN however, can someone who knows HP EVA help here.

  Also, I am very confused regarding mirrored ports and the need to be cautious when balancing the way between the controller.

  Which would be great if someone could give me a few white read books on it, the same and also fair knowledge base articles explain how to approach the above and examine the virtual machines as well.

  Not too big so... just small forum post I raised here... It will be useful someone help to get a dialogue going.

  What I do with my EVA, is having different LUNs (Datastores) manually selected a path preferred in command mode.  For example LUN 1,3,5,7 are on path then that lun 2,4,6,8 are set on Channel B.  This means that all your LUNS are also responsible.  On the ESX side each of my machines has 2 HBAs each with 2 paths that it looks like your Setup.  Here's what I think looks like load-balanced:

  ESX01-

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - LUN 1.2

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - LUN 3.4

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - MON 5, 6

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - MON 7, 8

  ESX02-

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - MON 5, 6

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - MON 7, 8

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - LUN 1.2

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - LUN 3.4

  It might not even be necessary have a configuration of blancing of load complicated if you produce not enough IO to saturate your current configuration.  You can just keep it like this:

  ESX01-

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - LUN 1.2

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - LUN 3.4

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - MON 5, 6

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - MON 7, 8

  ESX02-

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - LUN 1.2

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - LUN 3.4

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - MON 5, 6

• Displacement of the unit number logic from one ESX host to another

  I am a newbies VI3. Are there opportunities to move a unit logic of an ESX host number to another?

  I can't find any guide. Help, please.

  Thank you.

  You don't need to remove the LUN from the host of the first.

  It is enough to present the second ESX host storage, don't know how you do it for the EMC storage.

  If you have virtual center then you just select the host, go to Setup and select storage adapters and then rescan the HBAs. This storage should appear.

  If you do not have virtual Center, then you should be able to do it from the host.

  The main thing to make sure, it is that you present the LUN with the same ID for all guests.

  If you really need to delete a logical unit number not used, check that no virtual machines are using, use the management of storage to anyone there and then rescan the HBAs as above.

• How to add md1000 2.18 TB disk array to ESX host

  Hi, I am very new to VMware, and I try to add a picture of 2.18 TB md1000 disk to an ESX host.  When I go through the storage add wizzard, I see that he sees the md1000 2.18 TB of capacity, but shows only 1.8 GB available.  Anyone know what kind of configuration, I need to do for all the show of 2.18 TB as being available?

  Thanks a lot for your suggestions.

  John

  2 TB is the maximum for a single LUN.  You need to decreate your size of the LUN to less than 2 TB.

• Migrate ESX hosts to new SAN array

  Hello

  Our company has bought a new SAN storage array and we are looking for an overview on the migration of our ESX SAN infrastructure existing to the new array with minimal downtime. Currently, we use EMX DMX and will migrate to EMC Clariion.

  I thought that we could present the new table to the ESX host and then use SVMotion to move on the virtual machine, and then once we are full and everything is well, remove the old array. I don't know what the best solution practice to it would be...?

  Currently, we are on ESX 3.5 U2 in all areas.

  This sounds like a good idea? Any help is very appreciated!

  Thank you!

  -Mike

  It is exactly what you need to do.

  1. present LUNS of size equal to or greater than those on the existing table.

  2 format LUNS as VMFS data new warehouses.

  3 Svmotion VMs of new data warehouses.

  4. wait for a whille and ensure that everything is fine and then delete the old warehouses of data.

• New ESX host cannot see SAN fiber - Clariion

  Hello

  I spent about two hours, passing through communities and have tried various things without success... basically, I have a new ESX host that I've built, configured, and networked, but I can't see our existing SAN.

  The SAN is a Clariion CX3 - 10 c and it hosts all of our existing VMs (we currently have two hosts attached to the SAN)

  I have installed the CLI and Navisphere agent on the new host

  I have started to host and that you have ENABLED the two adapters Emulex HBA (host contains two HBAs installed) because they showed as disabled by default BIOS

  I have one of the HBAs connected to the fibre switch

  On the fibre switch, I have a flickering green light where I plugged the fiber cable, which makes me think, it is connected OK

  On the HBA, I have a green light and an orange light blink, which still makes me think the wiring is correct

  BUT I do not see the front Navisphere host, and the host cannot see all storage even after re-reading.

  Any ideas what to try next? I suspect that it is perhaps something to do with zoning - I must say the Emulex HBA how to find storage processors? If so, how can I go about it? From the BIOS by restarting the host and pressing ALT - E?

  Any help or advice appreciated...

  Assuming that hard zoning this site should provide you with some

  Help

  http://TechNotes.twosmallcoins.com/?p=16

  Also once the switch is zoned if the host is not listed on

  the Clariion Navisphere agent system has a config file that needs to be updated

  with the IP addresses of the SPs.

  You can also manually enter the host if necessary, but your

  probably zoning question.
