3. Select either the service mode or the identify function. (For this example, assume that you have selected the service mode function.) The list of pdisks is displayed again, and the disk drive module that you selected is marked by a >, which shows that the module is in the service mode. │ SSA SERVICE AIDS 8 238 │ │ SET SERVICE MODE 8 2381 │ │ SET SERVICE MODE 8 2382 │ │ SET SERVICE MODE 8 2381 │ │ │ │ Move cursor onto selection, then press Enter. │ │ │ │ {TOP} │ │ │ │ pdisk 11111111 - 4-P 2 GB SSA F Physical Disk Drive │ │ pdisk1 22222222 - 4-P 2 GB SSA F Physical Disk Drive │ │ pdisk2 33333333 - 4-P 2 GB SSA F Physical Disk Drive │ │ > pdisk3 44444444 - 4-P 2 GB SSA F Physical Disk Drive │ │ pdisk4 55555555 - 4-P 2 GB SSA F Physical Disk Drive │ │ pdisk5 66666666 - 4-P 2 GB SSA F Physical Disk Drive │ │ pdisk6 77777777 - 4-P 2 GB SSA F Physical Disk Drive │ │ pdisk7 88888888 - 4-P 2 GB SSA F Physical Disk Drive │ │ pdisk8 99999999 - 4-P 2 GB SSA F Physical Disk Drive │ │ │ │ │ │ │ │ {BOTTOM} │ │ │ │ F3=Cancel F1 =Exit │ │ │ Notes: a. You can select only one disk drive module at a time. b. If you select the service mode function, and the selected disk drive module is not in a closed loop (see "SSA Loops and Links" on page 3-59), your selection fails and an error message is displayed. Use the Link Verification service aid to identify any open-link problems before trying to reselect the service mode function. c. If you select the service mode function, and a file system is mounted on the selected disk drive module, your selection fails. Use the Configuration Verification service aid to determine which hdisk must have its file system unmounted before you can select the service mode function. d. If the check light of the disk drive module that you have put into the service mode does not come on, and if you are not sure of the location of that module, use the identify function to help you find the disk drive module (see "The Identify Function" on page 3-65). 3-70 Service Guide
