* 3097346 (3097342) AMF driver panics the node when AMF is being stopped.


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

Patch ID: 6.0.300.300

* 3267240 (Tracking ID: 3259682)

SYMPTOM:
Imf registrations for disk group resources fail.

DESCRIPTION:
If vxconfigd is unresponsive, then IMFD becomes unresponsive and
imf registrations fail for disk group resources. Subsequent attempts to
unconfigure AMF will also fail.

RESOLUTION:
The IMFD code is modified to fix this hang.

* 3331998 (Tracking ID: 3341320)

SYMPTOM:
Syslog gets flooded with "Cannot delete event (rid %d) in reaper" error
messages.

DESCRIPTION:
This was a harmless error message which appeared in syslog.

RESOLUTION:
AMF code is modified so that the error message does not appear in
the syslog.

Patch ID: 6.0.300.200

* 3230303 (Tracking ID: 3248251)

SYMPTOM:
AMF driver panics the machine while monitoring online processes.

DESCRIPTION:
For certain Linux kernel versions, when AMF is monitoring an online
process, AMF panics the machine while accessing kernel memory. The panic string
looks something like "BUG: unable to handle kernel paging request".

RESOLUTION:
Symantec has fixed this issue by modifying the AMF code that
accesses kernel memory.

Patch ID: 6.0.300.100

* 3090243 (Tracking ID: 3090229)

SYMPTOM:
AMF driver panics the node when vxconfigd is unresponsive.

DESCRIPTION:
The libusnp_vxnotify.so library used for disk group notifications,
goes into an infinite loop when vxconfigd daemon is unresponsive. This causes
AMF to enter an inconsistent state as a result of which AMF driver panics the node.

RESOLUTION:
Symantec has modified the AMF driver and libusnp_vxnotify.so
library, to address this issue.

* 3097346 (Tracking ID: 3097342)

SYMPTOM:
AMF driver panics the node when AMF is being stopped.

DESCRIPTION:
When AMF driver is being stopped, it stops the IMFD daemon. The
code to handle this sleeps while holding a lock. This causes AMF driver to panic
the node.

RESOLUTION:
Symantec has modified the AMF driver to fix this issue.
