Remove HP P9500 ldev reservation

Have you ever faced issues while deleting an ldev from HP XP or P9500 storage arrays? if yes, this is the right spot where you can find a solution. Most of the time the issue is related to lun reservation either caused by system software or cluster resources and you may not be able to delete it until you remove the reservation. There is an easy method to remove the lun reservation by using a utility which gets installed along with the HP DSM multipathing software, which we install for effectively load balancing the disk.
The utility is called HPprutil.exe, which is usually get installed under C:\Program Files\Hewlett-Packard\HP MPIO DSM\XP DSM\X86 along with HP DSM software.


The command HPPRUTIL DEVICES displays the type of reservation active on each device.

C:\Program Files\Hewlett-Packard\HP MPIO DSM\XP DSM\X86>HPprutil.exe devices
The requested operation is in progress.Please wait......
Device#  Device Name               Scsi Address    Reservation   NT Disk#
--------------------------------------------------------------------------
1        HP      OPEN-V-CM            1.0.0.0           None         Disk 1
2        HP      OPEN-V-CM            1.0.1.1           None         Disk 2
3        HP      OPEN-V-CM            1.0.2.0           None         Disk 3
4        HP      OPEN-V-CM            1.0.2.1           None         Disk 4
5        HP      OPEN-V               1.0.2.4           None         Disk 5
6        HP      OPEN-V               0.0.2.10          PR           Disk 6

The following are the types of reservation:

    1. SCSI       - Indicates a SCSI reservation on the device.
    2. PR         - Indicates a persistent reservation on the device.
    3. None       - Indicates the device is not reserved.
    4. SCSI/PR    - Indicates that a SCSI or persistent reservation exists on the device.

In the above example, you could see that device#6 has persistent reservation and if you try to remove the ldev using management console, it will fail. We can clear the reservation using HPPRUTIL command.

Let see how!

Command to Display and remove reservations present on devices are as follows,

HPPRUTIL DEVICES              : Displays details of reservation on devices.
HPPRUTIL CLEAR DEVICE=<#>     : Clears the reservation present on device #

open command prompt and change the directory to the source where the HPPRUTIL is located and use HPPRUTIL CLEAR DEVICE command.

C:\Program Files\Hewlett-Packard\HP MPIO DSM\XP DSM\X86>HPprutil.exe clear device=6
The requested operation is in progress.Please wait......
HPPRUTIL will attempt to clear the reservation on device 6.
Are you sure you want to continue (y/n)? y

Attempting to clear the reservation on device 6...
Successfully cleared the reservation on device.
C:\Program Files\Hewlett-Packard\HP MPIO DSM\XP DSM\X86>

You can see that the lun reservation has been cleared by the command. Run the command HPPRUTIL DEVICES  to verify the status.

C:\Program Files\Hewlett-Packard\HP MPIO DSM\XP DSM\X86>HPprutil.exe devices
The requested operation is in progress.Please wait......
Device#  Device Name               Scsi Address    Reservation   NT Disk#

3        HP      OPEN-V-CM            0.0.2.0           None         Disk 3
4        HP      OPEN-V-CM            0.0.2.1           None         Disk 4
5        HP      OPEN-V               1.0.2.4           None         Disk 5

Persistent reservation on the device has been removed. You can delete the lun from console without any issues now. 

Changing 3PAR SSMC administrator account

When you install 3PAR SSMC (3PAR StoreServ Management Console), the first time when you open SSMC, you will see a popup to set your administrator credential for your SSMC instance. You must set up the user name and password for the Administrator account if you want to proceed. But once you set the password you don't have an option to fix the credentials and password without logging in to the console. Think about a situation where you forgot the password or username? Let's see how to fix this.

By Default HP 3PAR StoreServ Management Console Server will be installed under folder C:\Program Files\Hewlett-Packard\SSMC and this will contain so many binaries to ease the SSMC operation. If you forget the SSMC Administrator credentials, clear the password by executing the script called ClearAdminCredential.bat  which is available in the SSMC\ssmcbase folder. You must run the script from a command prompt with administrator privileges.

open command prompt and execute ClearAdminCredential.bat

C:\Users\admin>"c:\Program Files\Hewlett-Packard\SSMC\ssmcbase\ClearAdminCredential.bat"This command will clear the SSMC Administrator Credential.Do you want to continue? [Y=Yes,N=No](default=N) Y
C:\Users\admin>

this will erase the current SSMC administrator credential and will prompt you to enter new credentials at the next login.
