Replacing a 14-in. disk drive unit

(continued)

Record the number of the controller card for the DDU replacement.

To post the controller card for the DDU, type

>CARD card_no

and press the Enter key.

where

card_no

is the number of the controller card recorded in step 6

Example of a MAP display:

Record the number of the DDU in use.

Note: In the display example in step 7, the number of the DDU is 0.

Find the state of the disk drive recorded in step 8.

To determine if open files exist on the DDU, type

>ALLOC

and press the Enter key.

Example of a MAP response:

Record the name and size (in blocks) of each volume on the disk.

If the state of the disk drive

being allocated

step 81
