4.1 Reserving Disk Space for Tape Tasks

The update and add-on process requires a minimum number of contiguous and non-contiguous disk space sectors. Ensure that you have enough contiguous disk space on LDEV 1 to complete your task. The total amount of non-contiguous disk space does not need to fit entirely on LDEV 1. Refer to Chapter 3 “Planning for Your Task”

To reserve disk space:

Log onto the console:
:HELLO MANAGER.SYS,INSTALL;HIPRI :SPOOLERLP;START :STREAMS streams_device
An LP device must be configured in SYSGEN. A common streams_device value is 10. Already spooled and streamed messages might display.
Reserve contiguous and non-contiguous disk space using the following default values or the estimate you made in Chapter 3 “Planning for Your Task”
:BUILDAXLDEV1.PUB.SYS;DISC=120000,1,1;DEV=1 :BUILD AXLSPACE.PUB.SYS;DISC=787000,32,32
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, make more space available on your system before you perform an update or add-on. Refer to Appendix C “Managing Disk Space”
Purge the AXLSPACE file. The AXLDEV1 file is automatically purged by the UPDATE tool.
:PURGE AXLSPACE.PUB.SYS
