Test the Disk Drives
The following example shows the listing for the disk from the example in Step 3
after the path has been successfully switched:
c. If you are testing a drive that is not mirrored, skip to Step 4e. Otherwise, enter:
->SWITCH $DATA00-MB
For the mirror drive of the $DATA00 disk, this command switches the preferred
path from the current preferred path, which is the mirror path ($DATA00-M), to
the mirror backup path ($DATA00-MB).
d. Enter the STATUS DISK $DATA00 command. See Step 3 to check that the
path switch occurred. Make sure the processor number in the Primary PID
column is the same as it was before the switch.
The following example shows the listing for the disk from the example in
Step 4b after the path has been successfully switched:
e. Enter the following SCF command:
->PRIMARY DISK $DATA00, 1
This command switches the primary processor from the current primary
processor to the backup processor.
f. Enter the STATUS DISK $DATA00 command. See Step 3 to check that the
processor switch occurred. Make sure the processor number in the Primary
PID column has changed to the number given in the command.
The following display shows that the primary processor was successfully
switched:
Successfully completing these commands indicates that the disk can be
accessed through both the primary and backup processors and through all the
paths.
