Comment 1 Ryan O'Hara 2007-11-08 17:06:54 UTC

Changing the title of this bug to more accurately reflect the problem.

Comment 2 Ryan O'Hara 2007-11-08 17:07:19 UTC

Fixed. Completely removed use of IP address as basis for SCSI reservation keys,
since this was causing problems. Instead, the SCSI reservation keys are now
based on the cluster ID and node ID. Specifically, the high 16-bits of the key
will be hex value of the cluster ID and the low 16-bits will be hex value of the
node ID.

Both the scsi_reserve init script and fence_scsi agent were modified for this
change.

Please note that this fix break compatability with older versions of fence_scsi,
since the new code will not recognize the old key format.
