Understanding Messages

To clear the locks during import, use the following command:

# vxdg -C import diskgroup

Caution Be careful when using the vxdisk clearimport or vxdg -C import

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

Caution Be careful when using the -f option. It can cause the same disk group to be

imported twice from different sets of disks, causing the disk group to become

inconsistent.

These operations can also be performed using the vxdiskadm utility. To deport a disk

group using vxdiskadm, select menu item 8 (Remove access to (deport) a

disk group). To import a disk group, select item 7 (Enable access to

(import) a disk group). The vxdiskadm import operation checks for host

import locks and prompts to see if you want to clear any that are found. It also starts

volumes in the disk group.

V-5-1-663

VxVM vxconfigd WARNING V-5-1-663 Group group: Duplicate virtual device

number(s):

Volume volume remapped from major,minor to major,minor ...

◆ Description: The configuration of the named disk group includes conflicting device

numbers. A disk group configuration lists the recommended device number to use for

each volume in the disk group. If two volumes in two disk groups happen to list the

same device number, then one of the volumes must use an alternate device number.

This is called device number remapping. Remapping is a temporary change to a

volume. If the other disk group is deported and the system is rebooted, then the
