Problem Description:

-------------------
 
4834892 : CST probe takes excessive cpu cycles on SAN based systems
4848104 : CST reports incorrect availability while an agent undergoes live upgrade
4863594 : CST consumes high CPU resource on systems with big /var/adm/messages

Steps for managing CST data in alternate boot environment/ Live upgrade
------------------------------------------------------------------------
When CST is used in an environment where more than one disk is
used to boot the OS, then please do the following steps:
 
1) Stop the cst process on the agent using:
   /etc/init.d/cst stop
 
2) Edit /var/opt/SUNWcst/cst.conf to create a new line:
   ALT_TSDIRPATH<\t>A_Directory_Path
 
In this line, A_Directory_Path should be a local disk(ufs)
which is mounted universally on the same mount point across
alternate boot environment. This serves as an invariant
reference point for CST to record correct outage data.
 
Note: The filesystem on which the alternate timestamp is written should
not be the root filesystem of the current boot environment and should
be present "as is" in the new boot environment.  This mount point should 
be specified in /etc/vfstab on both boot drive. Using /etc/auto_direct 
is not recommended.
 
3) Start cst using:
   /etc/init.d/cst start
 
These steps ensure that CST tracks the availability across alternate
boot disks and/or live upgrade properly.

Special Install Instructions:

None.
