Volume Management

Examples 

The following are examples on usage of the SHOWUSAGE command.

   1.  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

   2.  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:

              16
              16
            1200
            ----
            1232

   3.  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

   4.  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

   5.  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
             $00112060             3680      FILE1.GROUP1.ACCT1
             $00112EC0            16816      FILE2.GROUP2.ACCT1
             $00117070              864      <free space>
             $001173D0             1200      FILE2.GROUP2.ACCT1
             $00117880             1824      FILE2.GROUP2.ACCT1
             $00117FA0             2048      FILE2.GROUP2.ACCT1
             $001187A0              480      <free space>
             $00118980             4284      FILE1.GROUP1.ACCT1
             $00119AA0             4688      FILE2.GROUP2.ACCT1
             $0011ACF0             5648      FILE3.GROUP2.ACCT4
             $$0011D7E0           13088      FILE3.GROUP2.ACCT4

            Total sectors         62176

   6.  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
