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

Note: To test the coordinator disk group using the vxfentsthdw utility, the utility

requires that the coordinator disk group, vxfencoorddg, be accessible from two

nodes.

To test the coordinator disk group using vxfentsthdw -c

Use the vxfentsthdw command with the -c option. For example:

# vxfentsthdw -c vxfencoorddg

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

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.

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.
