dfm option set pmOSSVDirMaxSvRelsPerSecondaryVol=1

I'm having an issue setting up a 1-1 relationship with OSSV. I've been told the dfm option setpmOSSVDirMaxSvRelsPerSecondaryVol=1,

should create a new volume for each OSSV client but isn't working in my environment, when a 3rd OSSV client is added to dataset it creates a qtree.

I’ve set the following DFM options:

dfm option setpmOSSVDirMaxSvRelsPerSecondaryVol=1

dfm option setpmAutomaticSecondaryVolMaxSizeMb=1048576

The 1^st dataset add provisions two volumes for each OSSV client. The next dataset add creates a qtree

C:\Users\sambarnes47> dfpmdataset add ossvdataset1 upvstnmg003:D:\test030, upvstnmg005:D:/test050

Dataset dry run results

Hi Mark,
