Exception. Failed getting possible datastores .
Hi all,
trying vRPA in my lab and getting an error "Exception. Failed getting possible datastores ." at step 11.2 of the installer wizard. The datastores attached to hosts are iSCSI LUNs off HP StoreVirtual VSA (P4000). Any help to where I should start looking for clues?
Thanks!

Just to keep this forum updated on what was the issue in this case.
A single RP4VM cluster can connect to multiple vCenters (up to two vCenters per RP4VM cluster in this 4.2 release). That being said, the vCenter configured during installation must be the vCenter in which the vRPAs are deployed on. If there’s a need to add a 2nd vCenter, this can be done post-installation. In the issue described in this thread, the vRPAs were deployed on a different vCenter then the one configured in Deployment Manager.
Also, when there’s a need to separate the vRPAs load from production VMs load, the vRPAs can be placed on separate ESX cluster on the same vCenter. The only requirement is that ESX housing VMs to be protected has to have connectivity (same or routable subnet) towards the vRPAs.
This would be better clarified in the next documentation revision.
Hope that helps,
Idan

I would recommend starting with making sure that provided vCenter Credentials entered in Deployment Manager have admin privileges. Also make sure that those datastores are shared across all ESXs in the ESX cluster housing the vRPAs (assuming this isn't installed on a single ESX).
Let me know if that's helpful or you're still getting that error.

Thank you for reply, Idan.
I'm using domain admin credentials for the vCenter access, I'm able to log in with the same credentials using vCenter client without any issues. The datastores are shared to all nodes in the cluster (only two ESXi hosts there now).

Checked the vCenter logs, vRPAs were able to successfully log in. Pulled the logs from vRPA. The error is: "Failed finding one of the VMs in the VC"...
I had a single VM running in this cluster. Removed it from the inventory so there are no VMs in this cluster at all, re-run the datastore discovery - same error.

Any help figuring out what's going on? Thanks!

Hi,
Can you confirm that the credentials you're using can indeed browse and write to all datastores (permissions may of changed on a DS level). This is just to rule out any privileges issues.
If all DSs are accessible and writable with the user you are using, please contact me offline (email written below) in order to continue troubleshooting this, we will need logs from RP in addition to the DM logs you've already provided.
Regards,
Idan

Hi,
Please see my latest reply, this can be a permission issue.
If you have verified and it isn't, please let me know, I would need other logs besides installation server.
Regards,
Idan
