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 Lenovo 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 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
