Determining Available Disk 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 store 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.
