There are two external data sets that need to be identified to CA MICS StorageMate by each individual user before they attempt to use the product. These data sets are the: o Work Data Set o Tape Data Set A space reporting option also needs to be set, so StorageMate will know which method to use when reporting space usage for data sets managed by HSM. The functions of these data sets and options, and the procedure for defining them to CA MICS StorageMate are described below.
The Work Data Set
ALLOCATING THE WORK DATA SET
Before using CA MICS StorageMate, you must allocate a data
set that communicates with the StorageMate product. This
data set, known as the Work Data Set, is a PDS that contains
Volume Group Tables, Data Set Group Tables, generated JCL,
data set name pattern masks, the sample ACS routines created
from those masks, and other input or output members
associated with other StorageMate facilities.
The Work Data Set is defined by choosing the "Data Sets and
Processing Options" selection from the StorageMate and MICF
Options menu, and then completing the "Work data set" area on
the panel. The default Work Data Set name is
"userpref.MICSSTOR.CNTL", where userpref is the default
prefix for your TSO Userid. You can change this default name
to any valid TSO data set name. If you specify a data set
name that has not yet been created, you are shown a secondary
allocation panel that creates the new data set for you.
(This panel is similar to ISPF option 3.2). You should also
establish the practice of periodically compressing the Work
Data Set, and removing outdated or superseded members.
WORK DATA SET INTEGRITY
StorageMate users must recognize the importance of the Work
Data Set, and know that it is not automatically backed up by
CA MICS. If you do not have a regular backup procedure in
place for these types of data sets, you may want to build
some backup jobstreams and have them executed on a regular
basis either by the users or by a product administrator.
While many types of products can be used to perform this
backup, the example shown below uses the IEBCOPY utility to
back up a Work Data Set to tape:
//BKUPJOB JOB (accounting-parameters)
//BKUPWDS EXEC PGM=IEBCOPY
//*
//* PRIVATE WORK DATA SET BACKUP TO TAPE
//*
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD DISP=SHR,DSN=userpref.MICSSTOR.CNTL
//SYSUT2 DD DSN=userpref.MICS.MICSSTOR.CNTL(+1),
// DISP=(NEW,CATLG,DELETE),UNIT=unit,
// DCB=(userpref.MICSSTOR.CNTL),
// LABEL=(1,RETPD=360)
//SYSUT3 DD UNIT=SYSDA,SPACE=(TRK,(3))
//SYSUT4 DD UNIT=SYSDA,SPACE=(TRK,(3))
//SYSIN DD *
COPY INDD=SYSUT1,OUTDD=SYSUT2

The Tape Data Set
CREATING THE TAPE DATA SET While no information about the tapes in your tape library currently exists in the CA MICS databases, a method has been provided for optionally including this information in some of the reports produced by the CA MICS StorageMate product. You must first extract information about your tape library and place that information in a data set available to CA MICS StorageMate. Appendix C of this guide provides full details on the creation of this data set. While this data set may be prefixed with a TSO Userid, consider using a common prefix if multiple users will be running CA MICS StorageMate and accessing the data. Note also the data set will need to be refreshed regularly if you want it to contain the most current information about your tape library. You may want to schedule a daily production job that will do this, if you plan to use the data from this data set on a daily basis. SPECIFYING THE NAME OF THE TAPE DATA SET Once the external tape data set has been built, you must supply its name to CA MICS StorageMate. Choose the "Data Sets and Processing Options" selection from the StorageMate and MICF options menu, and then complete the "Tape data set" area of the panel. The first time you invoke the option, the default name of the tape data set will be "userpref.MICSSTOR.EXTAPE", where userpref is the default prefix for your TSO Userid. Replace this name with the name you chose for your Tape Data Set. The name you specified will be saved in your profile and will be used whenever you specify that tape information be included in a StorageMate report. Even if your Tape Data Set is created using the default name shown above, you must still use this option screen to update your profile with the correct name. Each individual user of CA MICS StorageMate must perform this step if they want to use tape data. Once your Tape Data Set is defined, you need not be concerned about this option again unless the name of the Tape Data Set changes, or you change your TSO Userid. Specifying a tape data set name does not automatically include tape data in all future StorageMate reports. Whenever you execute a StorageMate report that supports input from multiple sources, you are given the option on the report screen to specify the report sources that should be used for that report execution.
HSM Space Reporting Options
OPTIONS AVAILABLE FOR HSM SPACE REPORTING StorageMate supports reporting for data sets that are under control of HSM. Data sets fall under HSM control in one of two situations. In one case, data sets that have not been referenced recently have been moved from your online or "primary" volumes to HSM migration volumes. In the second case, one or more backup copies of the data sets on your primary volumes have been made on the HSM backup volumes. In either case, the space used on the HSM volumes for storing a data set is probably far less than the original amount of space allocated by the data set on the primary volume. This is because HSM uses such techniques as compression and data packing, and does not allocate any more space than is necessary to contain the data. CA MICS maintains three different values to indicate the amount of space allocated by a data set under HSM control, and StorageMate may be set to use any of these options when reporting space allocated by data sets on HSM volumes. These three values and their meanings are as follows: ACTUAL - refers to the actual amount of space being used on the HSM volume to contain the data. PRIMARY - refers to the original amount of space that was allocated on the primary volume by the data set before HSM took control of it. ESTIMATE - indicates an estimate of the amount of space that would be required if HSM moved the data set back to a primary volume. SELECTING THE REPORTING OPTION Once you have selected one of the options described above, you must indicate your choice to CA MICS StorageMate. Choose the "Data Sets and Processing Options" selection from the StorageMate and MICF options menu, and then complete the "HSM space value" area of the panel with one of the three keywords shown above. The option you have selected will then be used for all future HSM space reporting until you change it to a different value. When you run a StorageMate report that includes HSM data, a message in your MICSLOG output report will remind you of the option you are currently using. Running the same report with different HSM space options is a good method for doing disaster recovery planning, or for measuring the effectiveness of HSM processing.
