HP-UX iSCSI Software Initiator Support Guide, HP-UX 11i v1 and 11i v2, July 2005

Chapter 6

Troubleshooting

Diagnostics

The HP-UX Support Tool Manager (STM) has been modified so a user can select the iSCSI virtual node

entries in the STM map. However, when iSCSI devices are selected, all of the tools are grayed-out (not

available).

The HP-UX iSCSI Software Initiator works with HP-UX Event Monitoring Services (EMS) and the Support

Tools Manager (STM). By default, the iSCSI Software Initiator logs all diagnostic messages to the STM log

files. STM can be used to view the diagnostic messages logged in the STM log files.

EMS can be configured to automatically notify the system administrator when diagnostic messages are

logged by the iSCSI Software Initiator.

In addition to logging all diagnostic messages to the STM log files, the iSCSI Software Initiator logs some of

the diagnostic messages to the /var/adm/syslog/syslog.log file. For more details on diagnostic messages, see

Appendix C, “Diagnostic Messages,” on page 95.

If a problem cannot be resolved using the troubleshooting techniques listed in this chapter, provide the log file

generated by the iscsidiag tool to HP Support.

iscsidiag is an iSCSI Software Initiator debug information gathering tool.

Execute /opt/iscsi/bin/iscsidiag to capture the debug information.

The logfile will be placed in the /tmp/iscsidiag directory with a filename of: iscsidiag.<pid>.log

If you want to place the log file in an alternate directory, invoke iscsidiag as: /opt/iscsi/bin/iscsidiag

-t <directory_name>

Provide the log file iscsidiag.<pid>.log to HP Support for further assistance. The log file will be located

at the default location (/tmp/iscsidiag) or at an alternate location, if an alternate location has been

specified using the -t option.
