When a cluster is restarted, VxVM can refuse to auto-import a disk group for one of the following reasons:
A disk in the disk group is no longer accessible because of hardware errors on the disk. In this case, use the following command to forcibly reimport the disk group:
# vxdg -s -f import diskgroup
Note: After a forced import, the data on the volumes may not be available and some of the volumes may be in the disabled state.
Some of the disks in the shared disk group are not accessible, so the disk group cannot access all of its disks. In this case, a forced import is unsafe and must not be attempted because it can result in inconsistent mirrors.
