The SRNsSRN FRU List Problem10112 None Description: Format Degraded. A Format operation has beenended before it has completed.Action: Use the Format service aid to format the disk drivemodule.1XXXX Disk-drive module (100%)(“Disk Drive Modules” on page 3-17).Description: Disk drive module error.Action: Exchange the FRU for a new FRU.Note: In this SRN, an X represents a digit 0 through F.20PAA Disk-drive module (45%)(“Disk Drive Modules” on page 3-17).SSA adapter card (45%)(using-system Inst and Service Guide).| External SSA cables, Fibre-Optic| Extenders or fiber optic cables (6%).Backplane assembly (2%)(“Front Backplane Assembly” onpage 3-48 or “Back Backplane Assembly”on page 3-52).| Signal card or bypass card (2%)(“Signal Cards and Bypass Cards” onpage 3-43).Description: An open SSA loop has been detected.Action: Run the Link Verification service aid to isolate the failure| (see the chapter about SSA service aids in the SSA Adapters:| User’s Guide and Maintenance Information manual).If the SSA service aids are not available: When the failing device is in a 7133, go to step 12 onpage 2-2010-5 in “MAP 2010: 7133 – START.” When the failing device is not in a 7133, go to the serviceinformation for that device.21PAAto29PAADisk-drive module (45%)(“Disk Drive Modules” on page 3-17).SSA adapter card (45%)(using-system Inst and Service Guide).| External SSA cables, Fibre-Optic| Extenders or fiber optic cables (6%).Backplane assembly (2%)(“Front Backplane Assembly” onpage 3-48 or “Back Backplane Assembly”on page 3-52).| Signal card or bypass card (2%)(“Signal Cards and Bypass Cards” onpage 3-43).Description: An SSA ‘Threshold exceeded’ link error has beendetected.| Action: Go to the Intermittent Link Error MAP in the SSA| Adapters: User’s Guide and Maintenance Information manual.2A002 Disk-drive module (50%)(“Disk Drive Modules” on page 3-17).SSA adapter card (50%)(using-system Inst and Service Guide).Description: Async code 02 has been received. Probably, asoftware error has occurred.Action: Go to “Software and Microcode Errors” on page 2-8before exchanging any FRUs.2A003 Disk-drive module (50%)(“Disk Drive Modules” on page 3-17).SSA adapter card (50%)(using-system Inst and Service Guide).Description: Async code 03 has been received. Probably, asoftware error has occurred.Action: Go to “Software and Microcode Errors” on page 2-8before exchanging any FRUs.2A004 Disk-drive module (50%)(“Disk Drive Modules” on page 3-17).SSA adapter card (50%)(using-system Inst and Service Guide).Description: Async code 04 has been received. Probably, asoftware error has occurred.Action: Go to “Software and Microcode Errors” on page 2-8before exchanging any FRUs.2A005 None Description: Async code 05 has been received. This codeindicates that a disk drive module has detected the loss ofredundant power or cooling.| Action: Use 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 whether anydevices are missing from the SSA loop. If a device is missing, goto “MAP 2010: 7133 – START” on page 2-2010-1 to isolate theproblem.If no device is missing, the problem might have been caused by atemporary, or partial, loss of power to the 7133.2-4 7133 Service Guide
