Network Attached Storage Model 6RZ”)
v
IBM Ethernet and Fibre Channel network adapters (see “Adapter troubleshooting
and diagnostics” on page 96)
v
IBM 3534 Fibre Channel Hub Model 1RU (hub) (see “IBM 3534 Fibre Channel
Hub Model 1RU” on page 111)
v
IBM 5191 RAID Storage Controller Model 0RU (storage controller) (see “IBM
5191 RAID Storage Controller Model 0RU (storage controller)” on page 113)
v

IBM 5187 Network Attached Storage Model 6RZ
This section gives troubleshooting information for the IBM 5187 Network Attached
Storage Model 6RZ (engine).
Note: The information in this section must be applied to both engines in the Model
326. As an example, when the text reads, “The engine has light-emitting
diodes (LEDs) to help you identify problems,” this means that each engine in
the Model 326 has LEDs which require your attention.
As another example, the information contained in “Engine troubleshooting
charts” on page 89 applies to each of the two engines.
Engine diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
Note: If you need to remove the engines for inspection, do so one at a time:
remove an engine, inspect it, and put it back; then remove the other engine,
inspect it, and put it back.

POST beep codes, error messages, and error logs
The power-on self-test (POST) generates beep codes and messages to indicate
