Procedure 4-5
Disk drive procedures - recommended initialization
Step Description
2 Enter: (at the terminal)
>DISK DEFMAP x (cr)
where: x = drive = A = disk drive A
System response is a prompt:
ENTER HEAD AND CYLINDER #
FROM DEFECT MAP
ENTER "Q" TO EXIT
HEAD>xx (cr)
CYLINDER>xx (cr)
Continue entering HEAD and CYLINDER
numbers until the end of the disk
manufacturer's bad track map.
(For any response other than the HEAD and
CYLINDER prompts, see the procedure for
that message and perform the activities
listed.)
3 Once this procedure is complete, return to
the message procedure you left and
continue the activities.
Notes:
Note 1: This procedure is recommended for most disk maintenance situations where the manufacturer's bad track map is
available on site. After initialization, this bad track data should be entered using the DISK DEFMAP command.
Note 2: This is the default selection for DPP systems equipped with 380-Mbyte disk drives, without the 56K polling feature
(no NT6M94AA mounted in slot A7 of the DPP processor chassis).
Note 3: This selection is not valid for DPP systems equipped with:
a. 380-Mbyte disk drives with the 56K polling feature; if an NT6M94AA PCA is mounted in slot A7 of the DPP processor
chassis, disk initialization is not permitted.
b. 760-Mbyte disk drives, all instances.
Note 4: go to step 2 only if your DPP system is equipped with 72-Mbyte or 140-Mbyte disk drives.
Note 5: If your DPP system is equipped with 380-Mbyte disk drives, but no 56K polling, return to the message procedure you
were in and continue the activities listed.
