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:
- 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.
- 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.
- Shut down Server A. Shut down the Windows operating system on Server A, then power off the server.
- Perform maintenance. Perform the necessary maintenance on Server A.
- Power on Server A. Power on Server A and bring up the Windows operating system.
- 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.
