98Configuring VCS clusters for data integrity Preparing to configure disk-based I/O fencing

■If you use rsh for communication:

#/opt/VRTSvcs/vxfen/bin/vxfentsthdw -n

3The script warns that the tests overwrite data on the disks. After you review the overview and the warning, confirm to continue the process and enter the node names.

Warning: The tests overwrite and destroy data on the disks unless you use the -roption.

******** WARNING!!!!!!!! ********

THIS UTILITY WILL DESTROY THE DATA ON THE DISK!!

Do you still want to continue : [y/n] (default: n) y

Enter the first node of the cluster: galaxy

Enter the second node of the cluster: nebula

4Enter the names of the disks that you want to check. Each node may know the same disk by a different name:

Enter the disk name to be checked for SCSI-3 PGR on node galaxy in the format: /dev/sdx

/dev/sdr

Enter the disk name to be checked for SCSI-3 PGR on node nebula in the format: /dev/sdx

Make sure it’s the same disk as seen by nodes galaxy and nebula

/dev/sdr

If the serial numbers of the disks are not identical. then the test terminates.

5Review the output as the utility performs the checks and report its activities.

6If a disk is ready for I/O fencing on each node, the utility reports success:

The disk is now ready to be configured for I/O Fencing on node galaxy

ALL tests on the disk /dev/sdx have PASSED

The disk is now ready to be configured for I/O Fencing on node galaxy

7Run the vxfentsthdw utility for each disk you intend to verify.
