The following are examples on usage of the SHOWUSAGE command. To display what files are on a LDEV 1 enter the following:
volutil: SHOWUSAGE VOL=1 FORMAT=SUMMARY ;PERM
PERM space on LDEV 1:
FILE1.GROUP5.ACCT5
FILE2.GROUP1.ACCT1
FILE1.GROUP1.ACCT1
/dir/subdir1/subdir2/file1
FILE1.GROUP2.ACCT1
FILE2.GROUP2.ACCT1
/ACCT3/GROUP2/d1/f1
FILE3.GROUP2.ACCT4
|
To display which files consume the most space on LDEV1, enter the following:
volutil:SHOWUSAGE VOL=1 ;PERM
PERM space on LDEV 1:
SECTOR ADDRESS SIZE SPACE USED BY
(in sectors)
-------------- ------------ -------------
$00079DD0 672 FILE1.GROUP5.ACCT5
$000DDD00 16 FILE2.GROUP1.ACCT1
$000DDD10 16 FILE2.GROUP1.ACCT1
$000E2E40 208 FILE1.GROUP1.ACCT1
$000E3F60 1200 FILE2.GROUP1.ACCT1
$000E4160 464 FILE1.GROUP5.ACCT5
|
To find out the actual size of a file, add all of the sectors for that file,
for example, for FILE2.GROUP1.ACCT1, add: To display all files in the HFS (Hierarchical File System) syntax enter the
following:
volutil: SHOWUSAGE VOL=1 FORMAT=SUMMARY ;PERM ;PATH
PERM space on LDEV 1:
/ACCT5/GROUPS/FILE1
/ACCT1GROUP1/FILE2
/ACCT1/GROUP1/FILE1
/dir1/subdir1/subdir2/file1
/ACCT1/GROUP2/FILE1
/ACCT1/GROUP2/FILE2
/ACCT3/GROUP2/d1/f1
/ACCT4/GROUP2/FILE3
|
To quickly identify the minimum number of files that can be removed from LDEV 1 to free up 60000 sectors of contiguous disk space (for example to perform an UPDATE), enter the following:
volutil: showusage 1 60000 nonrestrict summary ;perm ;free
*Note: Only PERM space is displayed in SUMMARY format.
CONTIG PERM, FREE space on LDEV 1:
FILE1.GROUP2.ACCT1
FILE1.GROUP1.ACCT1
FILE2.GROUP2.ACCT1
FILE3.GROUP3.ACCT4
Total sectors: 62176
FILE1.GROUP3.ACCT1
/ACCT1/GROUP2/dir1/f2
FILE1.GROUP1.ACCT1
FILE5.GROUP5.ACCT5
Total sectors: 80416
|
To display the total sectors provided by the previous example containing the number of sectors used by free space (note that free space is not displayed in the previous example), enter the following:
volutil:showusage 1 60000 nonrestrict ;perm ;free
CONTIG PERM, FREE space on LDEV 1;
SECTOR ADDRESS SIZE SPACE USED BY
(in sectors)
-------------- ------------ -------------
$00111820 2112 FILE1.GROUP2.ACCT1

To display the maximum amount of contiguous block space enter the following:
volutil: SHOWUSAGE BSET:MEMBER2 10000 FORMAT=SUMMARY ;PERM ;MAX
CONTIG PERM space on BSET:MEMBER2:
FILEX.GROUP3.ACCTX
FILE1.GROUP1.ACCTX
/ACCTA/GROUPA/tmp/junk
FILE3.GROUP1.ACCTY
FILEX.GROUPM.ACCTB
Total sectors: 20264
FILEX.GROUPN.ACCTM
|
The following example, where the ;MAX option is not entered, is being presented as a comparison to the previous screen:
volutil: SHOWUSAGE BSET:MEMBER2 10000 FORMAT=SUMMARY ;PERM
CONTIG PERM space on BSET:MEMBER2:
FILEX.GROUP3.ACCTX
FILE1.GROUP1.ACCTX
/ACCTA/GROUPA/temp/junk
FILE3.GROUP1.ACCTY
Total sectors: 12032
FILEX.GROUPN.ACCTM
