Veritas Storage Foundation 5.1 SP1 for Oracle RAC Administrator"s Guide (5900-1512, April 2011)

To test the coordinator disk group using vxfentsthdw -c
1
Use the vxfentsthdw command with the -c option. For example:
# vxfentsthdw -c vxfencoorddg
2
Enter the nodes you are using to test the coordinator disks:
Enter the first node of the cluster: galaxy
Enter the second node of the cluster: nebula
3
Review the output of the testing process for both nodes for all disks in the
coordinator disk group. Each disk should display output that resembles:
ALL tests on the disk /dev/vx/rdmp/c1t1d0 have PASSED.
The disk is now ready to be configured for I/O Fencing on node
galaxy as a COORDINATOR DISK.
ALL tests on the disk /dev/vx/rdmp/c4t1d0 have PASSED.
The disk is now ready to be configured for I/O Fencing on node
nebula as a COORDINATOR DISK.
4
After you test all disks in the disk group, the vxfencoorddg disk group is ready
for use.
Removing and replacing a failed disk
If a disk in the coordinator disk group fails verification, remove the failed disk or
LUN from the vxfencoorddg disk group, replace it with another, and retest the
disk group.
