3.4.1 Creating a Volume Group Table

Volume Group Tables are created as follows:  Select the
Create Volume Group Table option from the CA MICS StorageMate
and MICF Options menu.  Selecting this option executes a
CA MICS StorageMate facility that creates your Volume Group
Table.  Depending on your environment, the next panel you see
may have the title "MICF Execution".  If this panel appears,
you should complete it and press the ENTER key again.  The
Create Volume Group Table report options screen should then
appear.

This screen has three required fields.  The first is the Unit
DBID(s) field.  In this field, enter the CA MICS unit
database ID (DBID) discussed in Section 2.2.  You can also
enter a question mark to see a list of the valid DBIDs
already defined by the CA MICS System Administrator.  The
second required field is the Cycle field.  Enter the number
of the cycle that will be read to create your table.  The
third required field is the Volume Group Table name field.
Enter a meaningful name for the table you are about to
create, because you will need to enter this name again when
you request a CA MICS StorageMate facility that does volume
grouping.

The Create Volume Group Table screen also has some optional
fields.  In the Default description field, you can overtype
the previous or default Volume Group name and replace it with
a name that will represent the pool with the largest number
of volumes assigned to it.  This name will appear as the
Volume Group name assigned to each volume in the table you
are creating.  You must then edit the Volume Group Table to
assign more meaningful names.  So if you specify the name of
the largest group as the default name, it will minimize the
amount of editing you will have to do later.  For example, if
90% of your volumes are IMS production volumes, specify a
default name such as IMSPROD.  Then you will only have to
change 10% of the volume assignments when editing.

Another optional field deals with the portion of the Volume
Serial Number (VOLSER) to use in creating the table.  The
default value is 6, which will include the entire VOLSER
value and will also use the SMS Storage Group name instead of
the default name you specified, if a valid Storage Group name
is present.  If you want to use less than six characters,
overtype the default with the value corresponding to the
number of characters you want to use.  For example, if you
have a SORTWORK pool that consists of volumes SORT01, SORT02,
SORT03, you can select all three volumes by changing the
value to 4, which causes the table to display an entry of
SORT*, which will select all volumes prefixed with SORT.

The last optional field determines whether volumes already
assigned an SMS Storage Group should be included in the
table.  The value you specify will also affect the way the
table is searched when it is used within a report, as
described in Section 3.4 of this guide.  Unless you are
simulating changes to your Storage Group definitions, you
will probably wish to code 'N' (No) for this option.

As with all StorageMate report option panels, you can use the
ISPF UP and DOWN keys to display the StorageMate Data
Filtering panel.  When creating a Volume Group table, data
filtering can be used to limit the volumes or systems that
will be included in the resulting table.

After you have modified the Create Volume Table report
options screen, press ENTER to validate your changes.  If no
error messages appear on your screen, all the values you have
entered are correct and you are ready to create your table.
To do this, press the END key, or type END on the command
line of the screen and press ENTER.
