you have a warm boot tape, and a good backup tape, you can normally recover all your data even if your
disk drive “crashes” and is unreadable.
Warm booting requires a special tape containing the proper system software files. You should have at
least two, and possibly more, warm boot tapes.
Your dealer or technician may have made warm boot tapes when he or she installed the computer. Check
with your dealer to make sure the proper warm boot tapes for your computer exist, whether they’re at
your office or your dealer’s.
As you become more familiar with your computer, we strongly recommend you create several warm boot
tapes. In addition, if you ever change the drive configuration or AMOS version of your computer, you
will almost certainly want to make all new warm boot tapes.
You can use the WRMGEN program to generate a warm boot monitor, and the appropriate backup
command to place the monitor onto a tape. See the AMOS User's Guide and the AMOS System
Commands Reference Manual for details on these procedures.
CHECKING THE DISK
A disk diagnostic program reads data from a disk. If it cannot read an area of the disk, it reports the
problem to you. Checking your disk frequently with disk diagnostic programs helps prevent data loss—
the sooner you catch a malfunction, the less data is likely to be affected.
Before using disk diagnostic programs, talk to your dealer. If you have an automatic backup
procedure, it may include a disk diagnostic program as well as the backup. You may not need to
use these programs separately.
If a diagnostic program indicates problems, you may need to restore data from a backup copy or
reconstruct the data on a damaged disk. If you have this type of problem, contact your dealer.
Before running a disk diagnostic program, especially if you suspect a problem, it is a good idea to use the
SET DSKERR command:
SET DSKERR
ENTER
This causes the computer to report the location of any errors the diagnostic program finds. If you don't
use SET DSKERR, you see only that an error occurred, not where on the disk it happened. You must run
the diagnostic program from the same job where you used SET DSKERR.
See Chapter 5 for a discussion of how AMOS organizes information on the disk.
The next two sections discuss two very useful diagnostic programs, REDALL and DSKANA. There is
more information on these disk diagnostic programs in the AMOS System Operator's Guide and the
AMOS User's Guide.
