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.

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).
