Starting ServiceGuard packages with degraded volumes
If you use ServiceGuard and PVLinks in an HP 9000 or HP Integrity system environment, the package startup time can take 20 - 60 minutes when you use the vgchange -a e VolumeGroupName command to start a package that contains a degraded volume.
Note: If you have
a degraded volume but
all of the associated nodes and MDisks are online, call the IBM®
Support Center for
assistance.
To avoid a lengthy startup time, complete the following actions:
- Do not start packages on an HP 9000 or HP Integrity system while you are updating the Storwize® V3700 system.
- Configure your HP 9000 or HP Integrity system so that each node is running a package that contains a volume from each I/O group. With this configuration, any automatic failover and failback to complete within a reasonable amount of time.
Note: The
lengthy startup time does not occur under the following
circumstances:
- If the host already has an active volume group that contains a degraded volume from the same I/O group
- If the host started while the volume was degraded
