Hello Kris,
can you post what vendor and storage model are you using for SRM?
We had a hard time few months ago when configuring Array Managers for SRM 5.1 on Hitachi storage array which returns some error specific to Hitachi CCI.
We didn't find any usable information's in SRA/SRM logs, Hitachi or VMware documentation/sources at the end after long attempt/false testing we discover
that Hitachi CCI needs undocumented system variable in place to work correctly.
So this is just the tip for further investigation or for check with your storage vendor...
Check also this KBs:
VMware KB: Storage Replication Adapter does not return any replicated devices/LUNs
Regards,
P.
