1. Are you exchanging a disk unit because a disk unit failure caused system operations to stop
completely?
v Yes: Continue with the next step.
v No: You may be able to use the Remove Units from Configuration function of DST. This function
allows you to move all data from the disk unit you want to exchange to the other disk units in the
same auxiliary storage pool (ASP). Go to step 17 (See page 550).
2. Perform an IPL to Dedicated Service Tools (DST). See Performing an IPL to DST in the iSeries

v No: Did any messages regarding missing disk units appear?
– Yes: Ignore the messages and go to step 3 (See page 546).
– No: Repeat this step. If the same system reference code (SRC) occurs again, the customer
data is not recoverable. Go to step 5 (See page 547). If a different SRC occurs, use it to correct
the problem. (See System Reference Codes.)
This ends the procedure.
