LVM Online Disk Replacement (LVM OLR)

LVM OLR Messages

pvchange(1M)

1. Usage: pvchange [-A Autobackup] [-s] | {[-S Autoswitch] [-x Extensibility] [-a Availability] [-t

IOTimeout] [-z SparePV]} PhysicalVolumePath

“a”: Illegal option.

This error is reported when pvchange(1M) –a y is attempted on systems that do not

have LVM OLR available.

2. The HP-UX kernel running on this system does not provide this feature. Install the appropriate

kernel patch to enable it.

This error is reported when the command patch is installed and the kernel patch is

not. Both the LVM command and kernel components are required to enable the

LVM OLR feature. If this message occurs, install the appropriate kernel patch to

enable the LVM OLR feature.

3. 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.

This warning is advisory and generated whenever a path or PV is detached to

emphasize the potential harm that could be done.

4. 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

This error is reported when the path specified is not part of any volume group, or

because the path has not been successfully attached before. If this error occurred

while detaching a path (using the –a n option) reissue the command using a path

that belongs to the volume group. If the error occurred while detaching a PV (using

the –a N option), specify a different path to the PV that is attached. If detaching a

PV (using –a N) fails, the same result can be accomplished by individually

detaching each path to the PV with pvchange(1M) (using –a n).

vgcfgrestore(1M)

1. Cannot restore Physical Volume /dev/rdsk/c7t2d0 Detach the PV or deactivate the

VG, before restoring the PV.

This error is reported when vgcfgrestore(1M) is used to initialize a disk already

belonging to an active volume group. If this error occurs, detach the PV or

deactivate the VG before attempting to restore the PV. If there is reason to believe

that the data on a given disk is corrupted, the disk can be detached and marked using
