Problem
Fencing will not start after server crashed (abnormal shutdown).
Error
VXFEN INFO V-11-1-VxFEN configured at protocol version 10
GAB INFO V-15-1-20026 Port b gen 816603 k_jeopardy ;1
VXFEN WARNING V-11-1-12 Potentially a
preexisting split-brain.
Dropping out of cluster.
Cause
SCSI-3 keys were not cleared at server reboot (abnormal shutdown).
Solution
Need to manually clear Fencing Keys using the following example:
# vxfenadm -g /dev/rdsk/c2t0d19s2
Reading SCSI Registration Keys...
Device Name: /dev/rdsk/c2t0d19s2
Total Number Of Keys: 2 <<== 2 keys.
key[0]:
Key Value [Numeric Format]: 65,80,71,82,48,48,48,51
Key Value [Character Format]: APGR0003
key[1]:
Key Value [Numeric Format]: 65,80,71,82,48,48,48,51
Key Value [Character Format]: APGR0003
Create a file /tmp/disks as follows for the disks that have key:
/dev/rdsk/c2t0d19s2
/dev/rdsk/c2t0d27s2
/dev/rdsk/c2t0d23s2
Then try running the following comamnds on this file:
# /sbin/vxfenadm –a –k TMP –f /tmp/disks
# /sbin/vxfenadm –c –k TMP –f /tmp/disks
# /sbin/vxfenadm -a -k TMP -f /tmp/disks
Registration and Ignore completed for disk path: /dev/rdsk/c2t0d27s2

Registration and Ignore completed for disk path: /dev/rdsk/c2t0d23s2
# /sbin/vxfenadm –c –k TMP –f /tmp/disks

Check if the keys exist:
# vxfenadm -g /dev/rdsk/c2t0d19s2
Reading SCSI Registration Keys...
Device Name: /dev/rdsk/c2t0d19s2

No keys...
Manually started fencing:
# /etc/init.d/vxfen start
Then, started VCS:
# hastart
