DFSMS APAR's VM59612 and VM62140 must be applied.
Verify DirMaint's EXTENT CONTROL contains the following:

```
2. The DEFAULTS section contains:

  or any number larger than 2 plus the number of DGTSRVnn ids.
3. Make sure the REGIONS section does not contain an entry for volume $$$$$$, or if present, the device type is 3380.

```
If any changes are made to the EXTENT CONTROL file, issue the DIRM RLDEXTN command.
Verify DirMaint's CONFIGnn DATADVH contains the following:

If any changes are made to the CONFIGnn DATADVH file, issue the DIRM RLDDATA command.
The following DirMaint commands must be issued by the DirMaint administrator for each minidisk server virtual machine (DGTSRVnn):
