I would like to know if it is possible for the following:
Assign 3 different groups of luns that will need to be assigned to 3 different fast policies to servers.
Within one Masking View
pSG =Parent Storage Group
cSG =Child Storage Group
Is it possible within the same Masking view
cSG1 -Fast Policy Gold
cSG2 -Fast Policy Silver
cSG3 -Fast Policy Bronze
A parent SG may have up to 64 child SGs. So your scenario is valid.
