Snap fails replicating, simulates fine

I did not have the RMSP2 installed, so that was causing some problems I believe. Here are the new error messages, that seem to be progress. This seems like it could be related to the fact that it's on a VM, so I don't really have a LUN attached to this host, it is attached to the server the VM is running on. Can snaps be done to VMs? or just clones?

Then followed by this a little later:

Well, I have it down to this now, after getting the raw data mapped LUN visible on the VM. Someone feel free to step in anytime! I don't have a host called dev-sql, because it's a VM. Is there some way I need to create a host in navisphere? Do I need to do something in my fabric manager? Pretty lost and new to this, any help is appreciated.

Hi Texrob,

Maybe if you could let us know what youare trying to achieve and in what type of environment, host OS, etc, it would better help us advise you.

I do recommend you look at the specifics in the user guide about mounting to an ESX host, as there are a number of steps which need to be performed prior to attempting to mount.

cheers

Thanks for the response.

The host is an HP BL460 blade in a C7000 chassis. It is a dual proc, quad core, 16gb of RAM blade. It is running two drives mirrored internally, with the ESX hypervisor installed onto those internal drives, so there is no host OS, or rather ESX is the host OS. It is ESX 3.5 update 2 with the time bomb patch applied, go VMWare!

I am trying to use RM to replicate a snap of our SQL databases to a VM host, for reporting purposes.

As far as the steps, I have done all the steps in the RM admin guide for ESX. I have created the snap devices in the storage group, and discovered the new LUNs in the infrastructure client and mapped them as RDM to the host. I am able to see the LUNs in the host OS in disk management in windows (server 2003 R2). RM writes to the tempundodir fine, it just seems to think it's not communicating properly.

Can I not do a SQL specific RM to a VM host? Do I need to try and just do a RAW lun snap? I hope not, because I really need it to mount automatically and be SQL aware.

Hi Texrob,

OK, the error "000382 ERROR: No storage group could be located for host" means that for reasons unknown (as yet), solutions enabler cannot find a match for the VM host on the Clariion. This could be for many reasons.

In order to continue to debug this, we would need the pertinent section of the RM debug log files at the time of error.

I would recommend that you set the mount host in debug mode in the console, run the mount again and open a support call so they can diagnose the issue in far more detail that here.

But what I would ask you to do is come back and share your results with the rest of us.

Cheers
James

I will have to do that. I was just trying to hit this thing when I have time, as it's not a top priority short term. I'll get a ticket opened at some point here soon.
