I found the below while reading OCUM 6.2RC1 OLH. Is this true ?
Rediscovering updated clusters manually
You can manually rediscover a cluster when you want to update it, such as increasing the size of an aggregate when there is insufficient space, and you want Unified Manager to discover those changes. If Unified Manager is paired with OnCommand Workflow Automation, this operation also triggers the reacquisition of WFA cached data.
Is the paring referred here the OCUM and WFA for protection workflows via OCUM UI ? Or is the genral paring that WFA uses to acquire data from OCUM.
