IBM V7000 SRA with SRM 5.1

There is a conversation going on in another thread

(http://communities.vmware.com/message/2227065#2227065)

- but it is an old thread and started off with different versions of everything.

I'm going to start a new thread based on current versions.

I cannot get the SRA to work with SRM 5.1

When I run a "test" failover for a simple recovery plan - I get this error:

"Error - Failed to create snapshots of replica devices. Failed to create snapshot of replica consistency group test1rep. SRA command 'testFailoverStart' failed for consistency group 'test1rep'. Volume cannot be created, please check test mdiskgroup cofiguration Refer to IBM SAN Volume Controller troubleshooting"

I'm running:

IBM v7000 Version 6.4.1.2 (build 75.0.1211301000)

vCenter 5.1

SRM 5.1.0-941848 on Windows 2008 R2 64 bit (2vCPU 8GB RAM)

SRM advanced settings
I have set the Advanced Settings option:
    storage.Commandtimeout to 1800 (def 300)
    storageProvider.hostRescanRepeatCnt to 3 (def 1)
    storageProvider.hostRescanTimeoutSec 1800 (def 300)

SRA v2.1.0.121224 (also tried 2.1.0.121108)
non-preconfigured environment

    Pre-Configured Env. not set
    Test MDisk Group ID set
    SpaceEfficient Mode = False

Is anyone having success with the IBM V7000 SRA (any version) with SRM 5.1?

Thanks
