FW 07.01.02/HAFM SW 08.06.00 HP StorageWorks HA-Fabric Manager Release Notes (AA-RUR6G-TE, August 2005)

Workaround
When a switch has been added to HAFM for ma nag ement, or firmware has been
upgraded, observe the switch being shown as discovered by HAFM. Check the event
log of the switch to ensure there were no faults that occurred during the short time when
HAFM was in the process of discovering the switch.
New sound files are not added to Event Manager immediately
New sound files do not display in the pull down menu of the Event Manager. They
cannot be selected for inclusion in a rule. In order for the new sound files to be
available, HAFM services must b e stopped and restarted, or the HAFM appliance must
be rebooted. This is not disruptive to managed switches, but monitoring and logging
functions are interrupted while the appliance is rebooting.
HP-UX paramet
ers may need to be changed before you run the HAFM client
The following
two HP-UX 11.0 kernel parameters are set too low for m ost
Java app lications. Usually you will see this problem as a java.lang.OutOf
MemoryError: unable to create new native thread error. To resolve
the issue, ed
it the following parameter limits:
• max_thread_proc—The ma ximum number of threads allowed in each
process. Theminimumvalue(anddefault)is64,whichisoftentoolowfor
most Java applications. Set the value of the max_thread_proc higher than
the expected maximum number of simultaneously active threads. The maximum
value is t
he value of nkthread.
• nkthread—The total number of kernel threads available in the system. This
parameter is similar to the nproc tunableexceptthatitdefines the limit for
the total
number of kernel threads able to run simultaneously in the system.
The value must be greater than nproc. The default is approximately twice that
of nproc. The maximum is 30000. The suggested value of nkthread is
2*max_thread_proc. If you have many Java processes running and each
running process uses many threads, you should increase this value.
Client HAFM Login dialog box is not displayed after logging out
In some cases, when the client has logged out, the Log In dialog box is not displayed.
If you get inconsistent behavior or an error m essage, restart the client. SAN data is
not affected when you restart the client.
HAFM appliance may shut down following a firmware download
TheHAFMappliancemayshutdownfollowingafirmware download. If this occurs,
you h
ave to restart the HAFM appliance to recover. This is an issue with Java Virtual
Machine 1.3.1_07, which is used in the application. This is only an issue when running
firmware 06.00.01 or earlier.
