When Good Disks Go Bad: Dealing with Disk Failures Under LVM (5900-3153, June 2013)

pvchange
"a": Illegal option.
Cause:
LVM OLR is not installed.
Recommended Action:
Install the patches enabling LVM OLR, or use an alternate replacement procedure.
The HP-UX kernel running on this system does not provide this feature.
Install the appropriate kernel patch to enable it.
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 to which it belongs.
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
