LDEV 1 Disk Drive Maximum Usage
If you have a CIO system and you are using a disk drive with over 2
GBytes capacity as your LDEV 1, any disk space over the 2 GBytes is
not available for use. It cannot and will not be used for system or user
files.
If you have an NIO system and you are using a disk drive with over 4
GBytes capacity as LDEV 1, any disk space over the 4 GBytes is not
available for use. It cannot and will not be used for system or user files.
The 9 and 18 GByte disk drive may be used as LDEV 1, but this not
recommended because a maximum of 4 Gb is usable by LDEV1.
The predefined variable hpcpuname contains the name of your computer
model as shown in this example:
:SHOWVAR hpcpuname
HPCPUNAME = Series 957
The following table lists NIO/CIO systems.

Estimating Disk Space Requirements
Before you begin to modify your system software make sure that you
have enough disk space to complete the modification. Modifying system
software includes: updating or reinstalling your system software and
adding on purchased products from the SUBSYS tape. There are three
types of disk space requirements that are referenced during the
modification process:
• The permanent (net) amount of non-contiguous disk space required
by the system software after it is modified.
• The maximum (peak) amount of non-contiguous disk space required
during the system software modification process.
• The amount of contiguous disk space the update tool (either
AUTOINST or HPINSTAL) requires to modify the system software.
