Backdating Your System
Planning Your Backdate
Validate Your System Backup (Method 1)
If you are using a CSLT (Method 1) to backdate your system, perform the steps in this
section.
If you are using a Factory SLT (Method 2) or a Factory Preload Tape (Method 3), proceed to
“Check for Disk Space.”
Before you begin the process of backdating, log on and verify that your backup tape is
valid.
1. From the console, log on with the following conditions.
:HELLO MANAGER.SYS,INSTALL;HIPRI
:SPOOLER LP;OPENQ
:STREAMS streams_device
where streams_device is the device number. A common streams_device value is 10.
An LP device must be configured in SYSGEN. Already spooled and streamed messages
might display.
2. Validate the backup created before you started the update process that you are now
backdating from. You need the valid backup to restore the NMCONFIG file.
Use the VSTORE command to make sure that the full backup is readable.
:FILE TAPE;DEV= tape_device
:VSTORE *TAPE;@.@.@;SHOW=OFFLINE;DIRECTORY
If your backup is not valid, you must use Method 2 or Method 3.
Check for Disk Space
Ensure you have sufficient disk space to backdate your system.
Refer to “Estimating Disk Space” in Chapter 3 , “Planning for Your Task,” and Appendix
C , “Managing Disk Space,” for additional information about these steps.
1. Reserve contiguous and non-contiguous disk space.
:BUILD AXLDEV1;DISC=n,1,1;DEV=1
:BUILD AXLSPACE;DISC=m,32,32
where:
n AXLDEV1 number, determined in Chapter 3 , “Planning for Your Task,”
or use the default of 120,000 sectors.
m AXLSPACE number, use the maximum value 1,084,000 (for 5.0 or 5.5
versions)
If a colon (:) prompt is returned. The files were built and you have enough disk space.
If you receive a message: Out
of disk space, you need to make more space.
2. Purge the AXLSPACE file. The AXLDEV1 file is automatically purged by the UPDATE tool.
:PURGE AXLSPACE
