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

Patch ID: 5.1.101.100

* 2481086 (Tracking ID: 2480982)

SYMPTOM:
The performance of the LLT-over-UDP configuration is slow, as compared to the 
LLT-over-Ethernet configuration. Also, the 'lltstat' command output shows 
higher retransmit and NACKS (negative acknowledgement) count.

DESCRIPTION:
The LLT-over-UDP configuration works over the IP layer, and is therefore a 
little slower than the LLT-over-Ethernet configuration. However, on the AIX 
operating system, the LLT-over-UDP configuration is more slow than expected due 
to a bug in the LLT transmit path.

RESOLUTION:
Symantec has modified the  LLT transmit path to fix this issue.


INSTALLING THE PATCH
--------------------
To Install the LLT51SP1RP1P1 patch on your system,
execute the following steps on all the nodes in the cluster:
1. Stop the stack

2. Verify that all the GAB ports have been closed:

3. Verify that LLT has been unconfigured:
   # /sbin/lltconfig
   LLT is not running

4. Verify that the LLT driver has been unloaded:
   # /usr/sbin/strload -qd /usr/lib/drivers/pse/llt
   /usr/lib/drivers/pse/llt: no
   If LLT driver is still loaded, "yes" will show up in the output above.
   Run below command to unload LLT driver.
   # /usr/sbin/strload -ud /usr/lib/drivers/pse/llt

5. Unzip the tar-zipped LLT patch that you downloaded from the Symantec site
