Instruction manual

See “Location Codes” in the operator guide for your system for general information
about location codes.
Problem Determination
For some problems, your system diagnostics tell you to check the lights on the system
to determine which part, if any, has a fault. “Controls and Lights” on page 7 of this book
shows the position of the lights. The diagnostic programs tell you what to report to your
service representative. (“Reporting Problems” on page 80 describes other information
you should report.)
Checking the SCSI Error Log
You can check the error log by running diagnostics in Problem Determination mode.
They check the error log and present messages about any problems that have been
logged. Your system manuals describe how to run the diagnostic programs.
Configuring a 2104 to the using system
Use the cfgmgr command to configure or reconfigure a 2104 to the using system.
Unconfiguring a 2104 from the using system
To remove a 2104 from the using system, use the following command:
rmdev -l [enclosurenumber] -d
where [enclosurenumber] is the enclosure device that was generated by the cfgmgr
command (for example, [ses0], [ses1], [ses2]).
Remove the ses_healthcheck job from the system cron table.
