I/O fencing disk test

This issue has been solved. See solution.

Hello,

While testing the disk to be used for fencing prior to configuration, I am being prompted for password for both nodes over and over again.

Kindly advise.

vxfentsthdw -r -w /dev/hdiskpower2 -n use /usr/bin/rsh

VERITAS vxfentsthdw version 5.1.1.0 AIX

The utility vxfentsthdw works on the two nodes of the cluster.
The utility verifies that the shared storage one intends to use is
configured to support I/O fencing.  It issues a series of vxfenadm
commands to setup SCSI-3 registrations on the disk, verifies the
registrations on the disk, and removes the registrations from the
disk.

The logfile generated for vxfentsthdw is
/var/VRTSvcs/log/vxfen/vxfentsthdw.log.1

Enter the first node of the cluster:
ibwebprod
root@ibwebprod's [1] password:
Enter the second node of the cluster:
ibwebstdby
root@ibwebstdby's [2] password:
root@ibwebprod's [3] password:

See "General guidelines for using vxfentsthdw" extract from the VCS admin guide:

 

The two nodes must have ssh (default) or rsh communication. If you use
rsh, launch the vxfentsthdw utility with the -n option.
 

So you need to setup ssh for root, or use -n and setup rsh for root.
