disk repaired -> cluster lock missing

[Laurent Coumes]

Hi,
After a disk replacement in a MC/SG cluster member (in a mirror) when have the message
WARNING: Cluster lock on disk /dev/dsk/c0t14d0 is missing! ...

What should we do to fix it ?

Regards

Laurent

Just run vgcfgrestore, if your LVM configuration file is updated.

If not you must apply the cluster configuration again. See cmapplyconf man page.

[melvyn burnard]

if the vgcfgbackup was NOT done after the disk was marked as a cluster lock disc, you will either have to re-apply the binary, taking hte cluster down first, or log a call wiht your local HP Response Centre and request the cminitlock utility.

If vgcfgbackup was not performed after the cmapplyconf command installed the cluster lock structure, then there are 2 other methods to resolve the problem.

First method:
To correct the problem while the cluster is running, download and use the tool in the manner described in the README portion of this file:

ftp://contrib:9unsupp8@192.170.19.51/crash/cminit.tar.shar

(unpack the file on the HP-UX server using this command: sh )

Second method (requires cluster be down):
1. Gather the cluster and package configuration files:

$ cmgetconf cluster.ascii
$ cmgetconf -p
Repeat for each pkg

2. Test the cluster configuration file:
$ cmcheckconf -C cluster.ascii

If it doesn't succeed, correct the problem before proceding.

3. Halt the cluster: $ cmhaltcl

4. Dissolve and recreate the cluster (a cmapplyconf by itself may not realize the cluster lock structure is defective and may not reinstall it):

$ cmdeleteconf -f
$ cmapplyconf -C cluster.ascii -P -P ...

5. Start the cluster:
$ cmruncl
