Service Request Numbers SRN FRU List % 2A006 Disk drive module 70 Backplane 30 2A106 Backplane assembly 100 2A206 Disk drive module 100 2FFFF None - Problem Description: Async code 06 has been received. This code indicates that a disk drive module has detected the loss of one of its power inputs. Action: If the failing device is an SSA Hot-Swap Disk Drive, go to "SSA Maintenance Analysis Procedures (MAPs)" on page 2-35, exchange the disk drive module. If the failing device is not an SSA Hot-Swap Disk Drive, go to the service information for that device. Description: Async code 06 has been received. This code indicates that multiple disk drive modules have detected the loss of one of its their power inputs. Action: If the failing devices are SSA Hot-Swap Disk Drives, exchange the backplane. If the failing devices are not SSA Hot-Swap Disk Drives, go to the service information for those devices. Description: A disk drive module has detected that one of its SSA links has failed the POSTs. Action: 1. Use the Link Verification service aid (see "Link Verification Service Aid" on page 3-73) to determine where the SSA link is broken. 2. Run diagnostics in the system verification mode to the two disk drive modules that are nearest to, and on each side of, the place where the link is broken. The diagnostics show which disk drive module detected the problem. Description: An async code that is not valid has been received. Action: Go to "Software and Microcode Errors" on page A-5.
