Cause:

LVM OLR is not completely installed. Both the LVM command and kernel components are required to

enable LVM OLR. In this case, the command patch is installed and the kernel patch is not.

Recommended Action:

Install the appropriate kernel patch to enable LVM OLR, or use an alternate replacement procedure.

Unable to detach the path or physical volume via the pathname provided. Either

use pvchange(1M) -a N to detach the PV using an attached path or detach each

path to the PV individually using pvchange(1M) –a n

Cause:

The specified path is not part of any volume group, because the path has not been successfully

attached to the otherwise active volume group it belongs to.

Recommended Action:

Check the specified path name to make sure it is correct. If the error occurred while detaching a

physical volume, specify a different path that it was attached to before. If it is not clear whether any

path was attached before, individually detach each path to the physical volume using pvchange with

the –a n option.

Warning: Detaching a physical volume reduces the availability of data within

the logical volumes residing on that disk. Prior to detaching a physical volume

or the last available path to it, verify that there are alternate copies of the

data available on other disks in the volume group. If necessary, use

pvchange(1M) to reverse this operation.

Cause:

This warning is advisory only and generated whenever a path or physical volume is detached.

Recommended Action:

None.

vgcfgbackup

Invalid LVMREC on Physical Volume.

Cause:

The LVM header on the disk is incorrect. This can happen when an existing LVM disk is overwritten

with a command like dd or pvcreate. If the disk is shared between two systems, it is likely that one

of the systems was not aware that the disk was already in a volume group. The corruption can also

be caused by running vgchgid incorrectly when using BCV split volumes.

Recommended Action:

Restore a known good configuration to the disk using vgcfgrestore. Be sure to use a valid copy

dated before the first occurrence of the problem.

# vgcfgrestore –n vgname pvname

vgcfgrestore

Cannot restore Physical Volume pvname

Detach the PV or deactivate the VG, before restoring the PV.

Cause:

The vgcfgrestore command was used to initialize a disk that already belongs to an active volume

group.

Recommended Action:
