Troubleshooting 149

Table 11-6 Troubleshooting Information: General Host Settings (continues on the following pages)

Problem Cause Recommended Action

A timeout might have occurred for the

Device Manager agent due to a

command such as an OS command

taking a long time to execute.

View the Device Manager agent

error log (error.log) to check

whether a command execution error

has occurred. Also, view the

information output in the log to check

whether a timeout (java

IllegalStateException) has occurred.

• If a device configuration

command, such as the AIX

command cfgmgr, the

Solaris™ command cfgadm, or

the HP-UX command ioscan,

that usually takes only a few

seconds to complete takes a

long time, there might be a

problem in the settings for host,

OS, or HBA. Alternatively, many

invalid device files might exist

due to a reason such as many

paths have been disconnected.

View the OS log or OS

documentation to remove the

cause, and then try again.

• If a timeout occurs when a

command is executed, re-set the

timeout value. Use the time

command to calculate how long

the command execution took,

and set the timeout value so that

it is about twice the calculated

time.

• If a timeout occurs due to the

hldutil command taking a

long time to execute, see the

Device Manager Release Notes

to re-set the timeout value.

• The system workload on the

host may have increased

because multiple processes or

applications were executed.

Stop any unnecessary

processes and applications, and

then re-execute.

• A configuration of a larger-scale

than Provisioning Manager

performance may have been set

up. A timeout is more likely to

occur when the above causes

occur concurrently. See HP

StorageWorks XP Provisioning

Manager Installation and

Configuration Guide, set the

timeout value to a larger value

than the initial value, and then

re-execute. Set the timeout

value so that the value is about

twice as long as the execution

time that was calculated by

using the time command.
