Reviewing Minidisk Allocations

You should occasionally review information about minidisk utilization and activity for the directory entries you manage. The information most important to review is the percentage of each minidisk that is being used and the last date each minidisk was updated. With this information, you can decide which minidisks are bigger than they need to be. Changing minidisk sizes and moving unused information out returns unused minidisk space to you for allocation to other directory entries.

The MDSKSCAN command provides this type of information, which you can display on your terminal screen or write to a file on your A–disk.

To review minidisk allocations

1. From CMS, enter the following:

   vmdirect mdskscan
   

   CA VM:Director asks for your logon password before it proceeds.

2. Enter your logon password.

   When CA VM:Director verifies your password, it displays information about the minidisks owned by the directory entries you manage. This display is similar to the following:

   ENTRY    VADR TYPE  BLKSZ FILES SIZE   %  DATE     TIME     MGR
   FRASIERC 191  CMS   1024  68     900K  50 yy/mm/dd 16:20:52 CARLAT
   FREDERIC 192  CMS   1024  17    1500K  32 yy/mm/dd 14:43:56 CARLAT
   LILITHS  191  CMS   1024  304   1000K  85 yy/mm/dd 10:07:35 CARLAT
   REBECCAH 191  CMS   1024  141   3000K  69 yy/mm/dd 16:58:39 CARLAT
   NICKT    200  CMS   1024  54     400K  77 yy/mm/dd 16:06:45 CARLAT
   

3. Review particularly the information in the percentage and date columns to find whose minidisks may have more space than necessary and whose minidisks have not been used in some time. These are good candidates for resizing.

   To write this information in a file instead of on the screen, enter:

   vmdirect mdskscan (file
   

   This command writes the information to a file named MDSKSCAN SCAN on your A–disk.

Note: For more information about this command, see MDSKSCAN Command in the Reference Guide.
