Ldev 1 Disk Space Report
For example, (to create files within the first
4GB of LDEV 1)
For all installation tools/applications such as PATCH/iX, AUTOINST, HPINSTAL,
AUTORESTART/iX, etc., the following equation is used to create AXLDEV1 (for the purpose of reserving space):
: BUILD AXLDEV1;DISC=n,1,1;DEV=1
n= AXLDEV1 number, determined in "Estimating Disk Space" given in System Maintenance manual or
use the default of 120,000 Sectors.
This above equation needs to be changed to
:
BUILD AXLDEV1;DISC=n,1,1;DEV=**$SYSTEM_MASTER
;DEV=1
For user files (i.e., for non system files) it is recommended that files are stored in private volumes. In the cases where user
files are stored in LDEV 1, using
the file commands, ;DEV=1 should be specified in the command. By specifying ;DEV=1
during creation, the system will attempt to create/store the files beyond 4GB
. If the required space is not available in the area
beyond 4GB, the system will create/store the files within the first
4GB of the disk.
Freeing
-up disk space within 4GB
During system update or otherwise, if there are OUT OF DISK SPACE (FSERR 46) errors even when the discfree utility
shows plenty of free space,
it may be required to free-up disk space within the first 4GB of LDEV 1 to enable system files to
reside there.
The following method can be used to free-up the disk space:
To identify where files are stored on LDEV 1, use the SHOWUSAGE command in VOLUTIL:
VOLUTIL:SHOWUSAGE 1;PERM;FORMAT=DETAIL
PERM Space on LDEV 1:

68384 25120 DISCUTIL.MPEXL.SYS
The sector address of 4GB is 16777216. Any
user
file having an address lower than this number is a potential candidate to
be moved
beyond the first 4GB of disk space.
Once the files are identified, you may use the following set of commands to move the files beyond 4GB:
