Maintaining a SIOS Protection Suite Protected System

When performing shutdown and maintenance on a SIOS Protection Suite-protected server, you must put that system’s resource hierarchies in-service on the backup server before performing maintenance. This process stops all activity for shared disks on the system needing maintenance. For off-line maintenance of a shared disk, see Off-Line Maintenance of a Shared Disk.

Perform these actions in the order specified where Server A is the primary system in need of maintenance and Server B is the backup server:

1. Bring hierarchies in-service on Server B. On the backup, Server B, use the LifeKeeper GUI to bring in-service any resource hierarchies that are currently in-service on Server A. This will unmount any file systems currently mounted on Server A that reside on the shared disks under SIOS Protection Suite protection. See Bringing a Resource In Service for instructions.

2. Stop LifeKeeper on Server A. In the Services tool, select LifeKeeper External Interfaces and click Stop. This will stop both services. Your resources are now unprotected.

3. Shut down Server A. Shut down the Windows operating system on Server A, then power off the server.

4. Perform maintenance. Perform the necessary maintenance on Server A.

5. Power on Server A. Power on Server A and bring up the Windows operating system.

6. Bring hierarchies back in-service on Server A, if desired. On Server A, use the LifeKeeper GUI to bring in-service all resource hierarchies that were switched over to Server B.
