SUMMARY OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
Patch ID: 7.1.0.100
* 3879189 (3878333) In SCSI-3 mode, I/O fencing fails to automatically refresh 
registrations on coordination disks.


DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following Symantec incidents:

Patch ID: 7.1.0.100

* 3879189 (Tracking ID: 3878333)

SYMPTOM:
With I/O fencing in SCSI-3 mode, if you enable the auto-refresh feature on the 
CoordPoint agent, then I/O fencing fails to automatically refresh registrations 
on the coordination points. This results in vxfen group to remain in faulted 
state.

DESCRIPTION:
Even to refresh registration on coordination disks, the vxfenswap script 
expects inputs about coordination disk groups from the CoordPoint agent. The 
CoordPoint agent does not provide this information to the vxfenswap script.
This causes the vxfenswap script to fail and the vxfen group remains faulted 
until it is manually cleared.

RESOLUTION:
The I/O fencing program is modified such that in SCSI3 mode fencing, the 
vxfenswap script does not explicitly require the coordination disk group 
information for refreshing registration keys on disks.
