Determining Available Disk Space
If you do not have enough disk space, determine how much disk space you do have available before you
proceed with clearing more space.
1. Determine available contiguous disk space on your system.
:run discfree.pub.sys;info=”B,ldev,volume_set_name”
Use option C to see each drive separately.
where:
ldev is the device number assigned to LDEV 1.
volume_set_name is the name assigned to the MPE system volume set.

TOTALS (IN SECTORS):
DEVICE SIZE : 10479136
TRANS SPACE : 30336 PERM SPACE : 7788944
MAX TRANS SPACE : 9169232 MAX PERM SPACE : 9169232
FREE SPACE : 2359856
AVAIL TO TRANS SPACE : 2359856 AVAIL TO PERM SPACE : 1210624
Verify that the amount following avail to perm space is greater than or at least equal to the axldev1
value.
The avail to perm space on LDEV1 indicates the space available on LDEV1. If you specifically want to
know if LDEV1 has contiguous free space available equal to the size of axldev1 within the first 4 GB of
LDEV1, invoke volutil.
Use SHOWUSAGE 1 contig=size of axldev1 in sectors>;free
If the sector address shown for this size is <=16777216, it means that a contiguous free space of <size of
axldev1 in sectors> within the first 4 GB is available.
2. Make additional space on the LDEV1 within 4GB if required, by again using volutil.
Invoke VOLUTIL. Use SHOWUSAGE 1;perm
Make note of the files that get listed within sector address 16777216. Store non-system files to tape using
the PURGE option to purge the stored files from the system.
If you generally require free space on LDEV1, discfree will show the available space. Make additional
space on the system by storing files to tape. Use the PURGE option to purge the stor files from the system.
Some files are scheduled to be stored and purged as part of the preparation process. These files include
USL, UNL, UXL, spool files, and log files. Estimate the size of these files and determine if you will have
enough disk space after they are purged.
