span of time. Discovery of a switch occurs when it is added to H AFM for managem ent,

and when the Ethernet connection to a switch is broken and reestablished, such as

when a switch’s ﬁrmware is upgraded.

Workaround

When a switch has been added to HAFM for management, 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 tha t occurred during the sho r t time when

HAFM was in the p rocess of discovering the switch.

New sound ﬁlesarenotaddedtoEventManagerimmediately

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 be stopped and restarted, or the H AFM appliance must

be rebooted. This is not disruptive to managed switches, b ut m onitoring and logging

functions are interrupted while the appliance is rebooting.

HP-UX parame

ters may need to be changed before you run the HAFM client

The followin

g two HP-UX 11.0 kernel parameters a re set too low for most

Java applications. Usually you will see this problem as a java.lang.OutOf

MemoryError: unable to create new native thread error. To resolve

the issue, e

dit the following parameter limits:

• max_thread_proc—The maximum number of threads allowed in each

process. Theminimumvalue(anddefault)is64, which is often too low for

most Java applications. Set the value of the max_thread_proc higher than

the expected maximum number of simultaneously active threads. The m aximum

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 tota

l 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 lo g ge d out, the Log In dialog box is not displayed.

If you get inconsistent behavior or an error message, restart the client. SAN data is

not a ffected when you restart the client.
