Chapter 6. Hardware maintenance
This chapter contains information to help you solve some of the simpler problems
that you might have with your storage server. It contains the problem indicators and
error messages along with suggested actions to take to resolve the problem.
For instructions on how to obtain service and technical assistance for your storage
server and other IBM products, see “Getting information, help, and service” on page
xxvii.
Note: See the IBM TotalStorage DS4000 Problem Determination Guide for
additional troubleshooting and debugging procedures.
General checkout
Use the status LEDs, Symptom-to-FRU index, and the storage management
software to diagnose problems. See “Checking the LEDs” on page 71.
To diagnose a cluster system, use the cluster problem determination procedure in
the IBM TotalStorage DS4000 Problem Determination Guide .
Note: If power was just applied to the controller unit, the green and amber LEDs
might turn on and off intermittently. Wait until the controller unit finishes
powering up before you begin to check for faults.
Using the diagnostic hardware
The DS4100 comes with an LC wrap-plug adapter and LC-LC coupler. The
wrap-plug adapter and LC-LC coupler are used to perform the loopback test and to
identify fibre path problems. See the IBM TotalStorage DS4000 Problem
Determination Guide for more information.
The loopback test and the sendEcho test are described in the IBM TotalStorage
DS4000 Problem Determination Guide . In the IBM TotalStorage SAN Integration
Server configuration, a loopback adapter (P/N 17P6918) is included to identify path
problems on the drive loop when using fibre channel 1.2 m copper cable (P/N
18P5237).
Solving problems
Always use the DS4000 Storage Manager client to diagnose storage server
problems and component failures. Also use the symptom-to-FRU index (Table 17 on
page 112) to find solutions to problems that have definite symptoms.
See the problem determination maps in the IBM TotalStorage DS4000 Problem
Determination Guide for more detailed procedures for problem isolation.
