The Start Media Balancing for BRM (STRBALBRM
) command balances expired media ownership to match the required number of media needed for systems within a BRMS network.
Notes:
1. You should make sure all BRMS activity is quiesced prior to balancing your media and all systems in the BRMS network are available (not in a restricted state).
2. BRMS will only balance expired media.
3. BRMS will not change the media class of media. If one class has additional media, BRMS will not change the media class.
4. This only needs to be set up on one system in the BRMS network.
The basic steps to use this command are as follows:
1. List your systems in the order of highest to lowest priority.
2. Set priority for each system. (If multiple systems have the same priority, BRMS will assign volumes to systems in alphabetical order)
STRBALBRM ACTION(*SET) MEDCLS(media-class) LOC(location) SYSNAME(system-name) MEDPTY(number) MEDREQ(number)
3. Print and review the Media Balance Report.
STRBALBRM ACTION(*REPORT) MEDCLS(media-class) LOC(location)
4. If necessary, balance the media using ACTION(*BALANCE).
5. Once again, print and review the Media Balance Report.
Example
Systems in network are :
PROD01
PROD02
DEV
Media Class used: ULTRIUM3
Tape Media Library device description: TAPMLB01
The steps to balance your scratch media are as follows:
1. List your systems in the order of highest priority to lowest priority.
System Priority Required
Prod01 1 5
Prod02 2 4
Dev 3 2
2. When you have established your hierarchy of systems, you must issue the following commands to set the above priority:
STRBALBRM ACTION(*SET) MEDCLS(ULTRIUM3) LOC(TAPMLB01) SYSNAME(PROD01) MEDPTY(1) MEDREQ(5)
STRBALBRM ACTION(*SET) MEDCLS(ULTRIUM3) LOC(TAPMLB01) SYSNAME(PROD02) MEDPTY(2) MEDREQ(4)
STRBALBRM ACTION(*SET) MEDCLS(ULTRIUM3) LOC(TAPMLB01) SYSNAME(DEV) MEDPTY(3) MEDREQ(2)
3. Print and evaluate the Media Balance report to ensure that your systems are setup correctly. To do so, run the following command:
STRBALBRM ACTION(*REPORT) MEDCLS(ULTRIUM3) LOC(TAPMLB01)

4. Once you have reviewed the report and you have determined that the actual amount of media is not greater to or equal to the required amount, you will need balance your media. To balance your media, you need to run the following command:
STRBALBRM ACTION(*BALANCE) MEDCLS(ULTRIUM3) LOC(TAPMLB01)
5. Print and evaluate the Media Balance report to ensure that your systems are setup correctly. To do so, run the following command:
STRBALBRM ACTION(*REPORT) MEDCLS(ULTRIUM3) LOC(TAPMLB01)
