Uninstalling an OSSM server

Edit online

You can remove an OSSM server from your IBM Storage® Protect Plus environment.

Before you begin

When permanently deleting the OSSM server, you must clean up the IBM Storage Protect Plus server. Items that must be cleaned up in this case, are as follows:
  • Records of backups that are stored on the OSSM server.
  • Replication relationships to other OSSM servers.
  • Ensure that no jobs use SLA policies that define the OSSM server as a backup location.

To view the SLA policies that are associated with jobs, see the Backup page for the hypervisor or application that is scheduled for backup. For example, for VMware backup jobs, click Manage Protection > Virtualized Systems > VMware. You must unregister the OSSM server from the IBM Storage Protect Plus server. See Unregistering an OSSM server for more information.

Attention: Uninstalling a OSSM server can result in loss of data.

Procedure

  1. Log on to the OSSM server console with the user ID serveradmin. The initial password is sppDP758-SysXyz. You are prompted to change this password during the first logon. Certain rules are enforced when creating a new password. For more information, see the password requirement rules in Start IBM Storage Protect Plus.

    You can also use a user ID that has OSSM administrator privileges that you create by using the ossm user create command.

    For more information about using console commands, see vSnap server administration reference. I don't think we have such section for OSSM. Just remove this line? or we have any reference?

  2. Run the following commands: 
    $ systemctl stop ossm
$ yum remove ossm
  3. Optional: If you do not plan to reinstall the OSSM server after it is uninstalled, remove the data and configuration by running the following commands: 
    $ rm -rf /etc/ossm
$ rm -rf /etc/nginx
$ rm -rf /etc/uwsgi.d
$ rm -f /etc/uwsgi.ini
  4. Reboot the system to ensure kernel modules are unloaded and detach the data disks containing OSSM pool data.
    Note: To uninstall IBM Storage Protect Plus in a Hyper-V environment, delete the IBM Storage Protect Plus appliance from Hyper-V and then delete the installation directory.

Results

After an OSSM server is uninstalled, the configuration is retained in the /etc/ossm directory. The configuration is reused if the OSSM server is reinstalled. The configuration is removed if you ran the optional commands to remove the configuration data.
