Yet another Cluster lock missing - Full info provided
Ok, here is the error i am constantly getting:
4e2058e61c0140WARNING: Cluster lock on disk /dev/dsk/c4t8d0 is missing! 4e2058e61c0140Until it is fixed, a single failure could 4e2058e61c0140cause all nodes in the cluster to crash
We are running a single node cluster for reason beyond my control, here is the output:
# cmviewcl -v CLUSTER STATUS clsigma1 up NODE STATUS STATE unix-1 up running Network_Parameters: INTERFACE STATUS PATH NAME PRIMARY up 0/1/2/0 lan0 PRIMARY up 0/4/1/0/6/0 lan1 STANDBY up 0/4/1/0/6/1 lan2 PACKAGE STATUS STATE AUTO_RUN NODE pkg_roi up running enabled unix-1 Policy_Parameters: POLICY_NAME CONFIGURED_VALUE Failover configured_node Failback manual Node_Switching_Parameters: NODE_TYPE STATUS SWITCHING NAME Primary up enabled unix-1 (current) Alternate down unix-2 NODE STATUS STATE unix-2 down unknown Network_Parameters: INTERFACE STATUS PATH NAME PRIMARY unknown 0/1/2/0 lan0 STANDBY unknown 0/4/1/0/6/1 lan2 PRIMARY unknown 0/4/1/0/6/0 lan1
Here is the ioscan:

Can anyone provide any insight on this...?
Thanks!

All it mentions in syslog.log is the same error as in my first post:

Re: Yet another Cluster lock missing - Full info provided
in syslog...i was really more interested in knowing if you were getting any disk hardware errors. You'll not be able to grep for cXtYdZ to find that out.
however since pvdisplay came back that seems to imply that the disk is still alive. (again, diskinfo output would be nice see)
Let's determine if a disk has a cluster lock structure loaded.
Perform the command on a cluster lock disk. An example of this command follows:
# echo '0x2084?4D' | adb /dev/dsk/c0t2d0
2084: 1 4194145 1010590466 256
^ ^^^ ^^^ ^^^
(lock flag) (lock location) (clusterID) (activation/
1=initialized, configured mode)
0=uninitialized
The 1 in the second column indicates that this disk is a cluster lock disk.

Here is the second command
echo '0x2084?4D' | adb /dev/dsk/c4t8d0 2084: 0 0 1706243227 256
I also tried it on a different disk and
# echo '0x2084?4D' | adb /dev/dsk/c5t8d0 2084: 0 0 1706243227 256
Does this mean there is no lock at all..?
Will this change if i start the other node..? Currently we are just running the cluster is a single node because of the ERP software, but if starting the other node fixes this, i can go ahead and do it, however, i dont think it will..
Any other ideas..?
Thanks

Re: Yet another Cluster lock missing - Full info provided
so -- we clearly see that the lock flag is not set -- and now the question becomes why? (and i wouldn't expect c5t8d0 to have the flag set)
backing up to to vgdisplay, i see:
Cur LV 5 Open LV 4
Cur PV 3 Act PV 2
why is that? what happened to this volume? if you do an "ls -l" of /etc/lvmconf/, what are the dates for the vg01 file(s)?

Basically the disk went bad and it was replaced.

Re: Yet another Cluster lock missing - Full info provided
according to your old thread and the lvm data you've shown in this thread -- this volume group is still is in an undesireable state.
any chance you could start over from scratch?
