Steps for detaching a snapshot VOLUME LUN and creat new volume copy from snapshot on HP P2000 MSA SAN VMWARE POWERCLI CLI

Step1. powerCLI (Only on the host where the VM is running)

    Shutdown & Power off the VM

 

Step2.  esxCLI (Perform on all hosts)
    a. If the LUN is an RDM, skip to step c. Otherwise, to get a list of all datastores mounted to an ESXi host, run the command:
 # esxcli storage filesystem list
    b. Unmount the datastore by running the command:
 # esxcli storage filesystem unmount [-u <UUID> | -l <label> | -p <path> ]
    c. Detach the device/LUN, run this command:
 # esxcli storage core device set --state=off -d NAA_ID
    d. To list the permanently detached devices: <Lists all detached LUN>
 # esxcli storage core device detached list
    e. Verify that the device is offline, run this command:
 # esxcli storage core device list -d NAA_ID
    f. Running the partedUtil getptbl command on the device shows that the device is not found.
 # partedUtil getptbl /vmfs/devices/disks/naa.?????????


Step3.  hpCLI
 # show volume-maps
 # unmap volume 10_23_LIS_Daily_C001


Step4.  esxCLI (Perform on all hosts)
  Rescan all devices on the ESXi host, run the command on all hosts:
    For rescanning vmhba2 only
 # esxcli storage core adapter rescan -A vmhba2
    For rescanning all adapters
 # esxcli storage core adapter rescan -a 


Step5.  hpCLI
 # show volumes
 # delete volumes 10_23_LIS_Daily_C001  (10 Seconds for 2.6TB partition)


Step6.  hpCLI
 # show volumes
 # show snapshots
 # show vdisks


Step7.  hpCLI
    To initiate volumecopy from the snapshot
 # volumecopy modified-snapshot no source-volume LIS_Daily dest-vdisk vd01 10_24_LIS_CLONE prompt yes  Success: Command completed successfully. (LIS_Daily) - The volume copy started. (2012-10-24 16:18:53)

    Check volumecopy status
 # show volumecopy-status


Step8.  hpCLI
    Map volume 10_24_LIS_CLONE with
    read-write access for
    HOSTS ESXHS01_vmhba2 and ESXHS02_vmhba2
    Using ports A1,A2 and B1,B2 and
    LUN 101:
 # map volume access rw ports a1,a2,b1,b2 lun 101 host ESXHS01_vmhba2,ESXHS02_vmhba2 10_24_LIS_CLONE
  
    To apply mapping to all hosts (Omit the host parameter, by default it applies to all hosts)
 # map volume access rw ports a1,a2,b1,b2 lun 101 10_24_LIS_CLONE
