Answered force mark tape as free doesn't work

    Hi @ all,

    I am using powershell for forcing tapes as free which are belonging to a single tape drive.

    Here is the script:

    $LIB = Get-DPMLibrary -DPMServerName server
    
$TP1 = Get-Tape -DPMLibrary $LIB
foreach ($rp in @(Get-RecoveryPoint -Tape $TP1))
{
Get-RecoveryPoint -Datasource $rp.Datasource | Out-Null

Write-Verbose "Removing recovery point created at $($rp.RepresentedPointInTime) for tape."
Remove-RecoveryPoint -RecoveryPoint $rp -ForceDeletion -Confirm:$false
}

Write-Verbose "Setting tape as free."

Set-Tape -Tape $TP1 -Free

    After running the script it throws an error which indicates, that recoverypoints can't be removed because they still belong to a protection group. Error ID: 31116

    Any hints?

     

    Cheers,

    André

    Please try this script.

            }

    Mike, sorry your script is more "detailed", but it uses Set-Tape as the André one.

    I'm verifying the same issue; I stop protection, the UI does not show anything in the Management/Libraries/Protection Group, but the DPM2010 always fires 31116! Set-Tape brings to the same result.

     $DPMLib = Get-DPMLibrary -DPMServerName "SRV-BACKUP"
     $Tape = Get-Tape -DPMLibrary $DPMLib

    PS C:\Users\Administrator.DOMAIN> write-host $Tape[1]
    Id = 86a1fcfb-a039-4f15-9f2c-d97cc2f23ead
    LibraryId = c07a0c13-9fff-406f-b272-e367e99ce38e
    IsOffline = False
    Location = Slot-40
    Label = HYPERV Full-LT-1Weeks-Copy0-00000004
    Type = TapeArchiveMedia
    StateInDrive = None
    BarcodeState = NotExisting
    BarcodeValue =
    MediaPoolId = 6e0056c1-fa61-4b6c-97a4-3de18084240a
    MediaPoolType = Admin
    OmidState = Recognized
    IsOmidChangeNeeded = False
    IsSuspect = False
    IsOffsiteReady = NotComputed
    DatasetState = Valid
    CreationDate = 21/08/2010 23:21:22
    ModifiedDate = 22/08/2010 00:04:49

    p.s. Of course I also rebooted :)

    ciao. pf

    I think you should try to run through the commands manually and see if this command is failing for any of the recovery points on that tape.

      Remove-RecoveryPoint -RecoveryPoint $rp -ForceDeletion -Confirm:$false

    Once all the recovery points are succesfully deleted, then the tape should be able to be marked free.

    Hi Mike,

    thanks for the script. I tried to run it against a tape which has one recoverypoint on it but it didn't work. I get the same error like above.

     

    cheers,

    André

    I've just recently used this script utility to mark a tape as free in dpm2010. Just beware of the typo in v3.4 of the script as noted in the blog's comments:

    Before using the dpmtapeutil.exe to erase tapes, please implement this registry key. 

    Short Erase
    http://technet.microsoft.com/en-us/library/ff634195.aspx

    When a user erases a tape, by default, DPM will do a long erase on that tape.  DPM 2010 has introduced the ability to do a short erase now.  Simply navigate to the following registry location and add the DWORD key with the default vale:

    HKLM\Software\Microsoft\Microsoft Data Protection Manager\Agent
    REG_DWORD:UseShortErase:0x0

     

    Here are some examples of the dpmtapeutil.exe commands for erasing tapes.

    NOTE: -batch does not prompt to confirm, so use with care.

    Example-1  eject offsite ready tapes

    .\dpmtapeutil.ps1 -batch -inventory -search "state=offsiteready"  -eject

    Example-2  Schedule forcefree tape for expired tapes every monday at 10:00am

    .\dpmtapeutil.ps1 -search "state=recyclable" -forcefree –schedule “Enable|Weekly|Mon|10:00”

    Example-3  Schedule tapeerase tape for expired tapes every 1 day at 10:00am

    .\dpmtapeutil.ps1 -search "state=recyclable" -tapeerase –schedule “Enable|daily|1|10:00”

    Example-4  tape erase for tapes that are free but contain data

     .\dpmtapeutil.ps1 -batch -search "state=freedata" -tapeerase -override
     
    Example-5   tape erase for ALL tapes in the library at noon everyday M-F (-override will force expiration of rp's before erasing)

     .\dpmtapeutil.ps1 -batch -tapeerase -override –schedule “Enable|weekly|Mon, Tue, Wed, Thu, Fri|12:00”

    example-6  tape erase all tapes that are in an unknown (raw tape) state.

    .\dpmtapeutil.ps1 -batch -search “state=unknown” -tapeerase -override

     

    If you don't need to schedule the erase and just need to free a tape manually, then use one fo these solutions.

    You can use the following power shell script to expire all RP on a given tape, then mark it free.

       http://blogs.technet.com/dpm/archive/2007/09/04/cli-script-force-mark-tape-as-free.aspx

    If you have a standalone tape drive - get the script from this post:

    Hello Rolando88,

    You can copy-paste the library friendly name from the output of get-dpmlibrary command before you run the force-freetape.ps1.

    If you are using the script on a standalone tape device (versus a library with multiple slots), you have to fill in the following for tape location:

    Drive-\\.\Tape0 where \\.\Tape0 is the windows symbolic name of the device when you highlight your tape drive in the DPM Console.

    Example:

    PS C:\Program Files\Microsoft DPM\DPM\bin> force-freetape.ps1
    DPM server name: : dpm1
    Library name: : Quantum LTO 4 drive
    Tape location: : drive-\\.\Tape2147483644
