Veritas Storage Foundation 5.1 SP1 Cluster File System Administrator"s Guide (5900-1738, April 2011)

# vxdg list vxfencoorddg | grep flags: | grep coordinator
■ Destroy the coordinator disk group.
# vxdg -o coordinator destroy vxfencoorddg
6
Add the new disk to the node and initialize it as a VxVM disk.
Then, add the new disk to the vxfencoorddg disk group:
■ If you destroyed the disk group in step 5, then create the disk group again
and add the new disk to it.
■ If the diskgroup already exists, then add the new disk to it.
# vxdg -g vxfencoorddg -o coordinator adddisk disk_name
7
Test the recreated disk group for SCSI-3 persistent reservations compliance.
See “Testing the coordinator disk group using vxfentsthdw -c option”
on page 74.
8
After replacing disks in a coordinator disk group, deport the disk group:
# vxdg deport ‘cat /etc/vxfendg‘
9
On each node, start the I/O fencing driver:
# /sbin/init.d/vxfen start
10
Verify that the I/O fencing module has started and is enabled.
# gabconfig -a
Make sure that port b membership exists in the output for all nodes in the
cluster.
# vxfenadm -d
Make sure that I/O fencing mode is not disabled in the output.
11
If necessary, restart VCS on each node:
# hastart
