Removed VMFS3 iSCSI target volume - I'm screwed?

Similar Questions

• Appropriate measures to remove LUN/iSCSI target?

  Hi guys, I'm under ESXi 5 and must remove some iSCSI LUN from a couple of hosts.  My first inclination was to just delete the target side SAN and then rescan.  But I thought I remembered reading somewhere that I should "detach" the LUN from the host first?  So I thought that maybe I should ask.

  Second question in the same sense, if I delete a full pathname, do I have everything just to delete the IP address in the 'Discovery' tabs, then rescan?  Thank you kindly.

• How to change the name of a volume iSCSI target?

  How the name of a volume iSCSI target can be changed?  I created a volume with a typo in a letter.   The volume production data on it now so I can not just it delete and recreate the problem.   It's not a big deal, but it doesn't look good either.

  It's on a PS6100.   When I go into the properties of the Volume in the advance tab I can see the iSCSI name, but cannot change it.  All I change is the public alias.  But it does no good that the name appears in the vCenter with the misspelled name.

  So how can I change the iSCSI name?

  Or am I stuck creating a new volume and telling them to migrate their data for spelling can be fixed?

  See you soon

  Part of the iSCSI specification is that target names must be unique.  Therefore, once created, you cannot change the name of the volume.

  Kind regards

• Static iSCSI targets removal script with PowerShell

  Hi all

  Is it possible to use PowerShell for the removal of static iSCSI Targets of script? If so, how...

  Thank you!

  If I understand you correctly, you want a report of current static iSCSI on your ESX Server targets.

  This should do the trick

  $esxName = 
  
  $report = @()
  $hostStorSys = Get-View -Id (Get-VMHost $esxName | Get-View).ConfigManager.StorageSystem
  foreach($hba in $hostStorSys.StorageDeviceInfo.HostBusAdapter){
       if($hba.gettype().name -eq "HostInternetScsiHba"){
            if($hba.ConfiguredStaticTarget -ne $null){
                 foreach($target in $hba.ConfiguredStaticTarget){
                      $row = "" | Select HBAName, hostname, device
                      $row.HBAName = $hba.Device
                      $row.hostname = $target.address
                      $row.device = $target.iScsiName
                      $row.port = $target.port
                      $report += $row
                 }
            }

• time machine remove the backup target drive

  Running El Capitan - I have set up three units for Time Machine backup: a RAID and a dock that is used for a pair of alternation of readers of archive. One of two archives training to life in a safe Bank and I have Exchange it with the current drive once a week.

  Before I upgraded my OS, Time Machine would simply be two backups between some readers were available and do so without comment. Now, after the upgrade, Time Machine sees that one of the pair is missing and he complains. This means that one time every three hours Time Machine issues a warning that one of the players is not available.

  I have not found a way to disable this warning.

  Be resigning myself to this, I decided that I simply change the names of readers Archives are identical, and then remove the 'third' drive in the list. With this version of Time Machine, I don't see a button "select disk" or any other way for the list of target readers and remove one of them. The options button allows you to control the volume of the source, not the target volumes.

  Either I have to stop the needless alert or remove a drive in the list.

  Any suggestions?

  Re: community - the only results of a search of a community of Time Machine is under Mountain Lion. Sorry if this is too broad

  After losing all kinds of weather (including a right click on the list of drives for backup and the research in all directions - including multiple searches on google), I discovered that you have right click on the drive icon in the list to use or remove the drive. This follows a different set of rules than the Finder user interface.

• Static configuration of iSCSI targets

  I was playing with New-IScsiHbaTarget, but has problems.  Each of my iSCSI Target names has the same IP address for the iSCSI server, and he didn't like that.  I tried something like:

  New-HBA target HBA - vmhba33-address 10.0.0.10 - static Type - nomiscsi iqn.2003 - 10.com.lefthandnetworks:blah:blah - 001

  and that seems to work, but when I tried:

  New-HBA target HBA - vmhba33-address 10.0.0.10 - static Type - nomiscsi iqn.2003 - 10.com.lefthandnetworks:blah:blah - 002

  He would say that "the specified target '10.0.0.10:3260' already exists... but I can't add these volumes manually using the client vSphere...

  We have a bunch of iSCSI volumes, and we are forced to use static targets for each.  For each vmhba on each host (vmhba33, vmhba35), without a script, we have to manually add each iSCSI target name.  So for 5 guests with 2 adapters for iscsi and 10 Mon, it's 100 steps.  Or someone at - it a script that can add several static targets?-preferably something that can extend over several hosts.

  Thank you very much!

  You're right, this looks like a bug.

  Until the problem is resolved, you can use the AddInternetScsiStaticTargets method directly.

  Something like that

  $iScsiHba = "vmhba33"
  $esx = Get-VMHost MyEsx
  $hStorSys = Get-View $esx.ExtensionData.ConfigManager.StorageSystem
  
  $tgt1 = New-Object VMware.Vim.HostInternetScsiHbaStaticTarget $tgt1.address = "10.0.0.10" $tgt1.iScsiName = "iqn.2003-10.com.test.iscsiA"
  $tgt2 = New-Object VMware.Vim.HostInternetScsiHbaStaticTarget $tgt2.address = "10.0.0.10" $tgt2.iScsiName = "iqn.2003-10.com.test.iscsiB"
  $targets = @()
  $targets += $tgt1$targets += $tgt2
  $hStorSys.AddInternetScsiStaticTargets($iScsiHba,$targets)
  

• Multiple ISCSI targets and connection failed

  last week I was preparing my s/w iscsi initiator to connect to multiple iscsi targets.  I ended up not doing last week, and I thought that I removed the targets of the GUI.  looking now @ the GUI, I only show my main production target, but if I look in my Journal vmkernel, his constantly trying to connect to these targets, I had the plan on connecting the box to.  Anyone know of a way for me to look @ the console and see where they can still be defined, of cause, they are not displayed in the GUI.

• NetWare as a iSCSI target

  Hello

  This problem is only a 'play' perspective (I'm experimenting with aspects of the VI3 before my VCP exam)...

  I am trying to use a NetWare 6.5 SP4 as an iSCSI target server. I have created the partition and can see the iSCSI SAN in vCenter, but after that it calculates the disk partition and tries to create the VMFS data on that store, it throws an error:

  Cannot open volume: vmfs/volumes / & lt; hexagonal long number & gt;

  There is no error message on the NetWare server.

  Any idea what would cause this? I'll try FreeNAS instead, but it will annoy me!

  See you soon,.

  Iain

  Been there, tried...

  NetWare will not work as a target iSCSI for ESX as it lacks support for iScsi RESERVE/RELEASE commands. With all those, ESX cannot use the target.

  Thank you very much for your help.
  I discovered the new external hard drive was the problem. Formatted as NTFS seems to be a problem so I reformatted to FAT and the problem disappeared.

• 'Incorrect function' during the initialization of an iSCSI target

  I have problems when you try to create a partition of 3.7 TB on Windows Server 2008 R2.

  

  I get the following error message when I try to initialize an iscsi target:

  

  What I am doing wrong.  The target is not part of a cluster.

  

  What I am doing wrong? I tried initilizating the disk with MBR and GPT time partitions and all do the same thing.

  Have you installed the software on the server (at least the host software) and establish connections iSCSI on two raid controllers? Looks like that may connect you to a controller, but the virtual disk is owned by the other controller.

• VMware as an iSCSI target

  Hello

  This might be a newbie question, but I looked in the documentation and online and I could not find a definitive answer.

  I want to configure my VMware machine as an iSCSI target, so that I can use additional storage to other machines in VMware.

  The hard drives are connected via SCSI on the local machine and not on a dedicated storage machine.

  Is this possible?

  Thanks for any response,

  Dorian

  Welcome to the community - Yes you can load a pack opensource like FreeNas and present as a target iSCSI in a VM - but I don't then point other virtual machines that are running on the same for your storage space because if the host fails your storage space will be would not available-

  I also move this issue a more appropriate forum

• Need urgent help: loss of storage after rename of iSCSI target

  Hello guys,.

  I need help, I had the problem with one of my iSCSI targets with all virtual machines on it, this iSCSI target on the storage iomega NAS device, is suddenly the storage is no longer available, I tried to rename the 'VmwareStorage' to 'VmwareStorage1' iSCSI target, but his is more appropriate (his was visible on a vsphere servers) but now visible sound like a DOS partition, please help to recover to vsphere without losing any data and the virtual machines inside. Note that I use Vsphere 5.5. see attached photo:

  the selected one is 16-bit DOS > = 32 M, its must be VMFS, as all other stores, I don't want to not loose my vms, the company stops and I'm fired

• Best practices the iSCSI target LUN

  I connect to my ESX laboratory to a QNAP iSCSI target and wonder what best practices to create LUNS on the target. I have two servers each connection to its own target. Do I create a LUN for each virtual machine, I intend to create in the laboratory, or is it better to create a LUN of the largest and have multiple VMs per LUN? Place several virtual machines on a LUN has concequenses HA or FA?

  Concerning

  It is always a compromise...

  ISCSI reservations are per LUN.    If you get many guests on the same logical unit number, it becomes a problem and Yes we saw it.

  Slim sure to layout.   This way you can make your smaller LUN and still get several s VM we each their.
