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

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, the 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.

    This will disable IMF functionality for all agents.

 2) Stop AMF:
        # /etc/init.d/amf stop 

 3) Uninstall the older version of AMF:
        # rpm -e VRTSamf 

 4) Use the appropriate command from the following list to install AMF patch:
    
     [RHEL 5]
        # rpm -Uvh VRTSamf-6.0.300.200-GA_RHEL5.x86_64.rpm 
    
     [RHEL 6]
        # rpm -Uvh VRTSamf-6.0.300.200-GA_RHEL6.x86_64.rpm 
    
     [SLES 10]
        # rpm -Uvh VRTSamf-6.0.300.200-GA_SLES10.x86_64.rpm 
    
     [SLES 11]
        # rpm -Uvh VRTSamf-6.0.300.200-GA_SLES11.x86_64.rpm 

 5) Start AMF:
        # /etc/init.d/amf start


REMOVING THE PATCH
------------------
1) Unconfigure AMF:
        # /opt/VRTSamf/bin/amfconfig -Uof
    
    This will disable IMF functionality for all agents.

 2) Stop AMF:
        # /etc/init.d/amf stop

 3) Uninstall AMF:
        # rpm -e VRTSamf
    
    NOTE:  This operation will remove the entire VRTSamf package.

 4) To fully revert your systems, install the previous version of VRTSamf from
    original source media and re-enable AMF.
