STEP 4
STEP 5
Check the disk voltages, PS2, using the YZ pages. If the disk voltages are correct, go to
step 5. Otherwise, use the Maintenance Information Procedures manual for troubleshooting.
Exchange the disk.
1. Replace (exchange) the hard disk (refer to "HOD Exchange Procedure" in the MIP
manual).
2. Initialize the new disk, as explained in "Initialize the Disk" on page 11-11.
Note: You must enter the serial number of the 3745 base frame.
After disk initialization, try to restore the disk from the diskette again (see STEP 2).
If the restore is successful, you have completed the procedure. Restart the job that pre-
viously failed.
If the problem persists, call higher support.
Procedure 2
Your latest set of backup diskettes is either invalid or not up-to-date. You will use the 'normal'
primary, secondary, third, fourth, and fifth diskettes (from the latest set of diskettes: initial installation
or latest EC).
STEP A
1. Set the 3745 in service mode 1 or 2 at the control panel.
2. Mount the primary 'backup' diskette.
3. IML in diskette mode (function 9 at the control panel).
4. Re-initialize the current disk, as explained in "Initialize the Disk" on page 11-11.
Note: You must enter the serial number of the 3745.
STEP B
Restore the disk from 'normal' primary, secondary, third, fourth, and fifth diskettes, that is,
the primary, secondary, third, fourth, and fifth diskettes containing the latest version of the
microcode (initial installation or latest EC).
STEP C
Use the restore disk option (3) of the 'DIF' function on the 3745 function menu 1 screen. See
"Restore the Disk from Diskettes" on page 11-8.
• If the restore is successful, go to STEP F.
• If the restore fails because of an 1/0 error, go to STEP C.
Replace the djsk file adapter card (DFA). Refer to the Maintenance Information Procedures
manual which explains the DFA replacement procedure.
After DFA replacement, try to restore the disk from the diskette again (see STEP B).
• If the restore is successful, go to step F.
• If the restore fails because of an 1/0 error, go to STEP D.
STEP D
Check the disk voltages, PS2, using the YZ pages. If the disk voltages are correct, go to
step E. Otherwise, use the Maintenance Information Procedures manual for troubleshooting.
STEP E Exchange the disk.
1. Replace (exchange) the hard disk (refer to 'HOD exchange procedure' in the MIP
manual).
2. Initialize the new disk, as explained in "Initialize the Disk" on page 11-11.
Note: You must enter the serial number of the 3745.
After disk initialization, try to restore the disk from the diskette again (see STEP B).
