Description

Below are the steps required to change/reset the password on the MSDP disk pools in the event it has been lost.

1. If the user name is unknown, find it with the following command:

Windows: <install_path>\volmgr\bin\tpconfig -dsh -all_hosts

Unix: /usr/openv/volmgr/bin/tpconfig -dsh -all_hosts

The user name will be listed after User Id:
====================================================================
Media Server:                        med-mak
Storage Server:                     med-mak
User Id:                                 root
    Storage Server Type:        BasicDisk
    Storage Server Type:        NearStore
    Storage Server Type:        SnapVault
    Storage Server Type:        PureDisk
====================================================================

2. To change the password when the password is known, use the following method:

Note - This is done on the MSDP server

Windows: <install_path>\pdde\spauser -c -u <user>
Unix: /usr/openv/pdde/pdcr/bin/spauser -c -u <user>

This will prompt for the old and new password, then it will change the password.

3. If the password is not known, then it needs to be manually changed following these steps.

For versions up to 8.1.1

a.  Choose a password and use an MD5 hash generator to generate a new password hash.

On Unix:
# echo -n "<Your desired Password>" | md5sum

Or go to the link http://www.md5hashgenerator.com/index.php, put the desired password in the string box and then click Generate.

b. Update the authentication credentials with the new password hash using the spadb command.

Windows: <install_path>\pdde\spadb -d <storage location>/databases -c "update authentication set passwd=5f4dcc3b5aa765d61d8327deb882cf99 where id=1"

Unix: /usr/openv/pdde/pdcr/bin/spadb -d <storage location>/databases -c "update authentication set passwd=5f4dcc3b5aa765d61d8327deb882cf99 where id=1"

In the example, the MD5 hash for a password of ‘password’ is: 5f4dcc3b5aa765d61d8327deb882cf99.

For version 8.1.2 and later

a.  Choose a password and run the spauser command.

On Unix: /usr/openv/pdde/pdcr/bin/spauser -r -u <username> -q <new_password>

On Windows: <install_path>\Program Files\Veritas\pdde\spauser.exe -r -u <username> -q <new_password>

4. Update the storage server credentials in NetBackup using the above username and chosen password:

Windows: <install_path>/Volmgr/bin/tpconfig -update -storage_server <server name> -stype PureDisk -sts_user_id <user id> -password <password>

Unix: /usr/openv/volmgr/bin/tpconfig -update -storage_server <server name> -stype PureDisk -sts_user_id <user id> -password <password>

For the above example for storage server named MSDP1 the command line will be
tpconfig -update -storage_server MSDP1 -stype PureDisk -sts_user_id root -password password
If the password is incorrect, the command will fail.

If you get the error - "Credentials for OpenStorage host <storageserver> do not exist." then add the credentials.
tpconfig -add -stype PureDisk -storage_server <Storageserver> -sts_user_id <user id> -password <password>

For the above example for storage server named MSDP1 the command line will be
tpconfig -add -stype PureDisk -storage_server MSDP1 -sts_user_id root -password password

5.  For NetBackup 8.3.X release changing password within WORM.

If user changes the password of MSDP with command 'setting MSDP-user reset-password' on the MSDP shell.

  User need to sync the MSDP password on the NBU side.​

given we have environment:

NBU  - master

NBU - media

MSDP1 - WORM storage server

 Windows: <install_path>/Volmgr/bin/tpconfig -update -storage_server <server name> -stype PureDisk -sts_user_id <user id> -password <password>

Unix: /usr/openv/volmgr/bin/tpconfig -update -storage_server <server name> -stype PureDisk -sts_user_id <user id> -password <password>

For the above example for storage server named MSDP1 the command line will be

tpconfig -update -storage_server MSDP1 -stype PureDisk -sts_user_id root -password password

If the password is incorrect, the command will fail.

If you get the error - "Credentials for OpenStorage host <storageserver> do not exist." then add the credentials.

tpconfig -add -stype PureDisk -storage_server <Storageserver> -sts_user_id <user id> -password <password>

For the above example for storage server named MSDP1 the command line will be

tpconfig -add -stype PureDisk -storage_server MSDP1 -sts_user_id root -password password
