HP e3000 MPE/iX System Software Maintenance Manual (Release C.75.00) (30216-90344)

Chapter 4

Preparing Your System

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:

1. Log onto the console:

:HELLO MANAGER.SYS,INSTALL;HIPRI

:SPOOLER LP;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.

2. Reserve contiguous and non-contiguous disk space using the following default values or the estimate you

made in Chapter 3, “Planning for Your Task.”

If you are currently running MPE/iX 7.5 (C.75.00) or later:

:BUILD AXLDEV1.PUB.SYS;DISC=120000,1,1;DEV=**$system_master

:BUILD AXLSPACE.PUB.SYS;DISC=787000,32,32

If youare currently running on a version of MPE/iX older than 7.5 (C.75.00) and are updating:

:BUILD AXLDEV1.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, and you are currently running on a version of MPE/iX

older than 7.5 (C.75.00),make more space available on your system before you perform an update or

add-on. Refer to Appendix C, “Managing Disk Space.”

If you are currently running MPE/iX 7.5 (C.75.00) or later:

If you receive a message, Out of disk space, in case of the build of AXLDEV1, you need to make more

space within the first 4 GB of LDEV1. If the message appears for the build of AXLSPACE, you need to

make more space on the system.

3. Purge the AXLSPACE file. The AXLDEV1 file is automatically purged by the UPDATE tool.

:PURGE AXLSPACE.PUB.SYS
