Ensure that CA MII Converts All Reserves

You must ensure that all RESERVES targeted at PPRCed DASD volumes are converted to global ENQs.

To ensure that all appropriate RESERVES are converted to global ENQs

Make sure CA MII is running with SUB=MSTR. This is required to manage the SYSZJES2 resource. Otherwise deadly embraces may occur.
Note: For more information on restrictions running SUB=MSTR, see the chapter “Advance Topics” in the CA MIM Programming Guide.
CA MII cannot use DASD(3390) control files: CA MII uses a hardware reserve to serialize its control file, and it cannot convert its own MIMGLOBL reserve. We recommend using COMMUNICATION=CTCONLY or XCF or DASDONLY(with XES list structures). To check your current communication method, issue the following command:
```
DISPLAY MIM IO  
```
Run GDIINIT PROCESS=ALLSYSTEMS and RESERVES=CONVERT. Issue the following command to determine your current operating values:
```
DISPLAY GDIF INIT     
```
Do not specify RESERVES=KEEP or GDIF=NO on any QNAME statement. Otherwise, you must ensure that the specification does not allow any hardware RESERVES to be issued against any PPRC-enabled DASD volumes. To review your current QNAME list, issue the following command:
```
DISPLAY MIM QNAMES                                                      
```
Run CA MII with SETOPTION GDIF EXEMPTRESERVES=NO, or make sure that none of your exempt list definitions result in a hardware RESERVE being issued against a PPRC-enabled DASD volume. To review your setting for this option, issuing the following command:
```
 DISPLAY GDIF OPTIONS
```
To review your exempt list, issue the following command:
```
DISPLAY GDIF EXEMPT
```
