5. Replace the cover and reinstall the blade server in the BladeCenter unit; then, restart the blade server. 6. If the blade server starts with the operating-system prompt, see "Recovering the primary image." If the blade server does not start with the operating-system prompt, replace the system board (see "Replacing the system board" on page 87). Note: If the blade server does not restart, you must replace the system board (see "Replacing the system board" on page 87). Recovering the primary image To recover the primary image, you must perform the reject function. The reject function copies the backup image into the primary image. To perform the reject function, complete the following steps: Note: If the operating system is Linux, begin with Step 001 . If the operating system is AIX, begin with Step 002 . Step 001 Complete the following steps: 1. If you have not installed the ppc64 Linux utilities, perform the installation now. See http://techsupport.services.ibm.com/server/ lopdiags/. 2. Reject the primary image. From the command line, type update_flash -r Step 002 then, go to Step 003 . Complete the following steps: 1. Reject the primary image. From the command line, type /usr/lpp/diagnostics/bin/update_flash -r then, go to Step 003 . or Note: Menu items that do not pertain will NOT be displayed if there is no temporary image; the "Reject the Temporary Image" menu entry will not appear as a possible selection. 2. From diagnostics, either concurrent or standalone: a. Run diagnostics v If you have booted AIX, login as ″root″ or use the CE login; then, at the command line, enter: diag v Otherwise, boot standalone diagnostics; then press Enter. b. From the Function Selection menu, choose Task Selection. c. From the Tasks Selection List choose Update and Manage System Flash. d. Choose Reject the Temporary Image. e. Choose Yes to reject the image. f. Press F10 to exit diagnostics. 56 BladeCenter JS20 Type 8842: Hardware Maintenance Manual and Troubleshooting Guide
