• Action: The action to be taken depends on the reason given in the error message:
Disk is in use by another host
No valid disk found containing disk group
The first message indicates that disks have been moved from a system that has crashed or
that failed to detect the group before the disk was moved. The locks stored on the disks
must be cleared.
The second message indicates that the disk group does not contain any valid disks (not
that it does not contain any disks). The disks may be considered invalid due to a mismatch
between the host ID in their configuration copies and that stored in the
/etc/vx/volboot file.
To clear locks on a specific set of devices, use the following command:
# vxdisk clearimport devicename ...
To clear the locks during import, use the following command:
# vxdg -C import diskgroup
CAUTION Be careful when using the vxdiskclearimport or vxdg-Cimport command on
systems that have dual-ported disks. Clearing the locks allows those disks
to be accessed at the same time from multiple hosts and can result in
corrupted data.
An import operation fails if some disks for the disk group cannot be found among the disk
drives attached to the system.
Disk for disk group not found
Disk group has no valid configuration copies
The first message indicates a recoverable error.
The second message indicates a fatal error that requires hardware repair or the creation
of a new disk group, and recovery of the disk group configuration and data:
If some of the disks in the disk group have failed, you can force the disk group to be
imported with this command:
# vxdg -f import diskgroup
