Direct MIMUNITS Entries to Certain Systems

You can share the MIMUNITS member among systems, even when you are using different local names on different systems, or when a device has the same local name as a different device on a different system. To share the MIMUNITS member under these circumstances, you need to direct entries to the appropriate systems.

To direct an entry, place an IFSYS statement before the entry and an ENDIF statement after the entry. On the IFSYS statement, specify the system name or system alias of the system (or group of systems) to which that entry applies. This tells CA MIA to use this entry only for the system specified.

For example, suppose that a device has the local name 01A0 on systems A and B and the local name 02A0 on systems C and D. To identify and assign global name G1A0 to that device, specify the following statements in the MIMUNITS member:

IFSYS A,B 
  01A0,G1A0 
ENDIF
IFSYS C,D 
  02A0,G1A0 
ENDIF

Notes:

• The letter “G” is used only for the global name examples and has no special meaning.
• For more information on IFSYS and ENDIF statements, and for information on assigning names and aliases to systems, see the CA MIM Programming Guide.

How You Exclude Devices from CA MIA Management

You can exclude devices from CA MIA management by coding a list of devices in the DEVEXCL CA MIA parmlib member.

To exclude specific devices during CA MIA startup, specify the following statement in your MIMINIT member:

MIMINIT DEVEXCL=membername

membername

Specifies a CA MIM parmlib member that contains a list of devices to exclude from CA MIA management. Code NONE if you do not want to exclude any devices from CA MIA> management.

Notes:

• The DEVEXCL=membername parameter is intended to be used with DEVCLASS=TAPE. This parameter combination causes CA MIA to discover and manage all manageable tape devices EXCEPT devices in the DEVEXCL= member.
• Using DEVEXCL=membername with the DEVLIST=membername parameter causes CA MIA to manage all devices in the DEVLIST= member EXCEPT the devices in the DEVEXCL= member.
• The same DEVEXCL=membername parameter was added to the CA MIA RESYNCH command. You can resynchronize CA MIA to exclude devices from being managed.
• The device exclusion list takes precedence over the MIMUNITS member. If MIMUNITS contains devices you have specified in the DEVEXCL member, they are excluded from CA MIA management.

Specify Devices in the DEVEXCL Member

The DEVEXCL member excludes devices from CA MIA management.

Example: DEVEXCL

************************************************
*          Sample DEVEXCL Member               *
************************************************
8000       /*Device  8000
810*       /*Devices 8100 through 810F inclusive
9000-A000  /*Devices 9000 through A000 inclusive

Each line in the DEVEXCL member specifies a single device or range of devices that CA MIA will NOT manage. The syntax of the DEVEXCL member is as follows:

• One device or range of devices per statement (line).
• Valid device numbers are hex 0000-FFFF.
• Specify a range with the ‘-‘character. For example, 1000-2000 specifies devices 1000 through 2000, inclusive.
• Specify a suffix of 0 through F with the ‘*’ character. For example, 800* would specify devices 8000-800F, inclusive.
• Direct your entries to specific systems by enclosing those entries in IFSYS/ENDIF statements. These statements are only applicable if you share the DEVEXCL member with other systems.
• Place an asterisk (*) in column 1 to indicate that this line is a comment.
• Place a slash (/) and then an asterisk (*) after an entry if you want to include a comment after the entry.
