Testing the disks using vxfentsthdw utility
This procedure uses the /dev/rdsk/c1t1d0 disk in the steps.
If the utility does not show a message that states a disk is ready, the verification
has failed. Failure of verification can be the result of an improperly configured
disk array. The failure can also be due to a bad disk.
If the failure is due to a bad disk, remove and replace it. The vxfentsthdw utility
indicates a disk can be used for I/O fencing with a message resembling:
The disk /dev/rdsk/c1t1d0 is ready to be configured for I/O Fencing on
node galaxy
To test the disks using vxfentsthdw utility
1
Make sure system-to-system communication functions properly.
2
From one node, start the utility.
Run the utility with the -n option if you use remsh for communication.
# vxfentsthdw [-n]
