v If the CD-ROM boots on the second server, replace the JS20 system board in the JS20 you were originally trying to boot. v If the CD-ROM fails on the second server, replace the CD drive in the media tray. 5. If replacing the CD-ROM does not resolve the problem, replace the media tray. 6. If booting on all servers fails using the new media tray, replace the following in the BladeCenter unit: v Management module v BladeCenter backplane 004 If you are attempting to boot from an IDE disk. 1. Verify that the IDE disk is installed. If you are trying to boot from the second IDE disk, verify that the second IDE disk is installed. 2. Select the CDROM as the boot device. 3. Perform Chapter 4, "Problem determination procedures for AIX and Linux," on page 21. 4. Reload the operating system onto the disk if boot attempts from that disk continue to fail. 5. Replace the suspect disk if you are not able to load the operating system. 6. Replace the system board and retry loading the operating system. Physical location codes Locations are visible when you are viewing event-log entries on the management module. Un generally refers to the enclosure, where n is the machine type, model, and machine/system serial number of that enclosure. For a blade server, this would be the fully assembled blade server, its machine type, model, and machine/system serial number (the unique identifiers that identify the individual blade server asset against which an IBM warranty is provided). The physical location code gives no indication of the location of the blade server within the BladeCenter unit. Physical location codes are within the domain of the enclosure, which in this case is the individual, fully-assembled blade. The machine type, model, machine/system serial number identify a blade server by a unique name, not a location. Pn generally refers to an instance of a system board. Tn generally refers to an instance of a connector or port Cn generally refers to an instance of a card Dn generally refers to an instance of a DASD or disk Component Blade assembly Blade base system board Daughter card Blade Storage Expansion PCIX (BSE-PCIX) DIMM1 DIMM2 Location code Un = Uttttmmmsssssss Un-P1 Un-P1-C5 Un-P1-C6 Un-P1-C1 Un-P1-C2 154 BladeCenter JS20 Type 8842: Hardware Maintenance Manual and Troubleshooting Guide
