SRN FRU List Problem43PAA Disk drive module (90%)(“Disk Drive Modules” on page 3-17).SSA adapter card (10%)(using-system Inst and Service Guide).Description: An SSA device on the loop is preventing thecompletion of the loop configuration.Action: If the SSA service aids are available, run the Link| Verification service aid (see the chapter about SSA service aids| in the SSA Adapters: User’s Guide and Maintenance Information| manual) to determine which device is preventing configuration.(That device is the one beyond the last-configured device on anopen SSA loop.)If the SSA service aids are not available, note the value of PAAin this SRN, and go to “Finding the Physical Location of a Device”on page 1-58.44PAA Disk drive module (100%)(“Disk Drive Modules” on page 3-17).Description: A disk drive module has a ‘Failed’ status.Action: If the SSA service aids are available, run the Link| Verification service aid (see the chapter about SSA service aids| in the SSA Adapters: User’s Guide and Maintenance Information| manual) to find the failing disk drive module. If no device is listed| with a status of “Failed”, use the PAA part of the SRN to| determine which device is failing. Before you exchange the| failing device, run diagnostics in System Verification mode to that| device to determine the cause of the problem.| If the SSA service aids are not available, note the value of PAA| in this SRN, and go to “Finding the Physical Location of a Device”| on page 1-58. Exchange the failing FRU for a new FRU.45PAA Disk drive module (40%)(“Disk Drive Modules” on page 3-17).| Adapter card (40%)| (using-system Inst and Service Guide).| External SSA cables, Fibre-Optic| Extenders, fiber optic cables, or| internal SSA connections of the 7133| (20%)Description: The SSA adapter has detected an open SSA loop.Action: If the SSA service aids are available, run the Link| Verification service aid (see the chapter about SSA service aids| in the SSA Adapters: User’s Guide and Maintenance Information| manual) to determine which part of the loop is failing.| If the SSA service aids are not available, note the value of PAA| in this SRN, and go to “Finding the Physical Location of a Device”| on page 1-58. Then go to “SSA Link Errors” on page 2-11 to| solve the problem.| 46000| None| Description: A RAID array is the Offline state because more than| one disk drive is not available. At least one member disk drive of| the array is present, but more than one member disk drive is| missing.| Action: Go to the SRN table in the SSA Adapters: User’s Guide| and Maintenance Information manual, and follow the instructions| for this SRN.| 47000| None| Description: An attempt has been made to store in the SSA| adapter the details of more than 32 RAID arrays.| Action: Go to the SRN table in the SSA Adapters: User’s Guide| and Maintenance Information manual, and follow the instructions| for this SRN.| 47500| None| Description: Part of the RAID array data might have been lost.| Action: Go to the SRN table in the SSA Adapters: User’s Guide| and Maintenance Information manual, and follow the instructions| for this SRN.| 48000| None| Description: The SSA adapter has detected a link configuration| that is not valid.| Action: Go to the SRN table in the SSA Adapters: User’s Guide| and Maintenance Information manual, and follow the instructions| for this SRN.| 49000| None| Description: A RAID array is in the Degraded state because a| disk drive is not available to the array, and a write command has| been sent to that array.| Action: Go to the SRN table in the SSA Adapters: User’s Guide| and Maintenance Information manual, and follow the instructions| for this SRN.2-6 7133 Service Guide
