SRM test fails to connect shadow LUN on SVC in time

Hi all,

I´d like to discuss the following with you, I´m pretty new with SRM but I understand the basics. Please hear my story:

I have a twin data center, both sites have a vSphere environment with ESXi hosts and VirtCenter server running W2K8R2. I installed the SVC SRA and SRM recently and wanted to run a little test failover. Unfortunally this has failed, for a unknown reason.

What happens?

Well first it is going to prepare the storage and attach disks for the protection group, after this the power on of the test VM fails. I never get further than this.

looking at the log files I see these thing happen (I took out lots of parts by the way):

[2011-02-10 14:09:23.415 03100 warning 'SecondarySanProvider'] Timed out (30 sec) waiting for change on 'datastore' for 'vim.HostSystem:host-44'

[2011-02-10 14:09:23.792 02056 warning 'SecondarySanProvider'] Failed to prepare shadow vm for recovery: (dr.san.fault.RecoveredDatastoreNotFound) {
[#1]    dynamicType = <unset>,
[#1]    faultCause = (vmodl.MethodFault) null,
[#1]    datastore = (dr.vimext.SanProviderDatastoreLocator) {
[#1]       dynamicType = <unset>,
[#1]       primaryUrl = "sanfs://vmfs_uuid:4d37e0e1-be371768-cb2e-e61f135e9b97/",
[#1]    },
[#1]    reason = (vmodl.MethodFault) null,
[#1]    msg = "",
[#1] }

As you can see it can´t find its shadow LUN (the shadow copy). Does anyone know why it takes so long for the host to see it´s failover datastore?

the SRA config is set to `Pre-Configured environment` and is using R3 failover with ShadowCopy, after a while the recoverd LUN is showing on the host but then the test has already failed.

So what am I doing wrong here? Anyone have seen this before?

Regards,

Peter.
