Hi Guys,
After a reboot done on the server, I am able to access the VG again, in fact while I am trying to shutdown the server it self, it hang and take long time till I need to force shutdown from HMC.
Thanks a lot guys.
First off, i am glad you could resolve your issue. But: a reboot is (most times) not the way to resolve things. After all, we are not on Windows - we use a real OS with real error-correcting capabilities.
Most probably your issue came from a "VG lock". The SCSI-protocol (which is also used with FC-connected disks as "iSCSI") can lock a disks so that any other attempt to use it will fail. You need such locks for disks which are accessed from more than one system, like in clusters. Sometimes such a lock is placed wrongly and not removed so that it prevents further management of the disk. You need to break such a lock before continuing.
You do that by

cmdisklock
cmdisklock(1m)cmdisklock(1m)NAME
cmdisklock - manage Serviceguard cluster lock devices.
SYNOPSIS
cmdisklock check path
cmdisklock [-f] reset path
DESCRIPTION
cmdisklock is a tool to check the current state of a Serviceguard cluster lock device. It can also be used to reset the state of the clus-
ter lock device. The need to reset the cluster lock device state could arise if the cluster lock device is replaced or becomes corrupt.
A cluster lock device can be either an HP-UX LVM cluster lock or a cluster lock LUN device. HP-UX LVM cluster locks exist only on a disk
in an LVM volume group. Cluster lock LUNs exist only on disks dedicated to cluster lock. cmdisklock is useful for checking either type of
cluster lock and for re-initializing cluster lock LUN devices after a failure or corruption.
NOTE
To restore an HP-UX LVM cluster lock, use vgcfgrestore. cmdisklock will fail until vgcfgrestore is run, and cmdisklock is unnecessary as
long as vgcfgbackup was done after the cluster lock was initialized. See the Managing Serviceguard manual for details.
The syntax of the path option depends on the type of lock. For HP-UX LVM cluster lock disks, the syntax is VG:PV (for example:
/dev/vglock:/dev/dsk/c0t0d2). For cluster lock LUN disks, the path is the disk device path. For example, /dev/sdd1 (on Linux) or
/dev/dsk/c0t1d2 (on HP-UX).
Options
cmdisklock supports the following options:
check Check the current state of the cluster lock device and report the results.
reset Reset (initialize) the state of the cluster lock device. This operation should only be performed on a cluster lock
LUN device. For HP-UX LVM cluster lock, use vgcfgrestore as documented in the Managing Serviceguard manual. After
performing a reset, a check can be used to verify that the lock is cleared.
EXAMPLES
If the cluster lock LUN device becomes corrupted and the cluster is up, messages like the following will appear in syslog.
Mar 15 12:20:41 usb cmdisklockd[17599]: WARNING: Cluster lock LUN /dev/dsk/c0t1d2 is corrupt: bad label. Until this situation is cor-
rected, a single failure could cause all nodes in the cluster to crash.
Mar 15 12:20:41 usb cmdisklockd[17599]: After ensuring that all active nodes in the cluster have logged this message, run 'cmdisklock reset
/dev/dsk/c0t1d2' to repair
Mar 15 12:20:41 usb cmdisklockd[17599]: Cluster lock disk /dev/dsk/c0t1d2 is inaccessible
Once the above messages appear in syslog on all running nodes, the following command will re-initialize the cluster lock LUN:
ucd:/> cmdisklock reset /dev/dsk/c0t1d2
WARNING: Cluster lock LUN /dev/dsk/c0t1d2 is corrupt: bad label. Until this situation is corrected, a single failure could cause all nodes
in the cluster to crash.
After ensuring that all active nodes in the cluster have logged this message, run 'cmdisklock reset /dev/dsk/c0t1d2' to repair
/dev/dsk/c0t1d2 is inaccessible
Resetting cluster lock device /dev/dsk/c0t1d2
Cluster lock reset completed
/dev/dsk/c0t1d2 is accessible
cleared
After the lock is restored, a message like the following appears in syslog:
Mar 15 12:23:11 usb cmdisklockd[17599]: Cluster lock disk /dev/dsk/c0t1d2 is accessible
WARNINGS
CAUTION
For cluster lock LUN, reset is a potentially destructive operation. While cmdisklock checks for known volume manager and file system use
(overridden by -f), it does not validate that the device to be reset is actually used by any cluster. If -f is used on the wrong device
file, loss of data may result.
CAUTION
Care should be taken when doing a reset when the cluster is active as there is a remote possibility that the cluster will partition right
when this command is run and both nodes could end up thinking they have successfully acquired the lock. To avoid this situation, make sure
cmcld has logged a message in syslog on all running nodes saying the device is inaccessble, before performing a reset. Note that it is
safe to run cmdisklock when the cluster is down.
RETURN VALUE
cmdisklock returns the following values:
0 Successful completion.
1 The disk is inaccessible or is not recognized as a cluster lock.
