Hi,
I've set up a simple test environment with a single VM, datastore etc which worked fine, I'm now testing a failover with about 19 LUNs and about 50 VMs.
vCenter 1.01 patch 4
SRA Clariion v1.3.0.4
2 x VCs servers
2 x SQL servers
2 x CLARiiON SANs
Mirrorview configured and SANs replicated,
Snapview configured for each LUN with VMWARE_SRM_SNAP
Setup looks fine, My problem is that when I hit test, the storage gets mounted to my recovery site, but about 5 of the LUNs are missing...?
SRM conifiguration looks fine...
Any suggestions? I've uploaded the logs and look forward to your response.
Thanks,
Craig.
What are the names of the Datastores that are missing?
Double check that all the Snaps are added to the Storage group on the SAN at the recovery site. just in case you've missed them at all.
mmm. One thing I have just noticed is that all the snapshot LUNs that fail to mount are all on SPB of the CLARiiON array. Interesting.
Interesting. Nothing wrong with the fabric zoning? I imagine that'd all be setup OK, assuming you have other LUNs on SPB already that are presented successfully to the ESX servers?
Thanks for your reply BobbyTPI,
Yes, I don't get it, everything looks fine, the same config with a simple implementation which works fine, I've even checked that the snapshots are created in the reserve LUN pool on the SAN (which they all are) there just seems to be an issue when presenting them to the ESX hosts.
I've looked at the HLU's for each LUN/snapshot until I'm blue in the face, no config issue there, theres about 19 MetaLUNs/LUNs and 19 snapshots...
Any suggestions anyone?
Just wanted to provide the solution to this.
I noticed that the SCSI Target 0 for each ESX hosts only listed a single path, so I looked at the FC Zoning configuration but all looked fine...
Basically the SPB was the answer, the ESX hosts are configured with a single HBA in this POC, for some reason the path to SAN port B-5 was assigned to the management LUN only, I edited the Host Connectivity Status, selected SP-Port B5 and hit the reconnect button.
I then went to the ESX host in VC and rescanned all LUNs, this fixed the problem, both SCSI Targets listed all paths to all (Meta)LUNs / Snapshots.
All good, thanks to those who viewed / replyed to this post.
if you installed the latest clarIIon SRA, you get a free amazing bonus,
an EMC software called Mirrorview Insight Viewer", this Graphical tool shows you if your luns have been created properly,
if they are being replicated and it also gives you an automated SRM FAILBACK!!

We're using VI3.x, solution enabler 6.5.30 and SRM 1.01-patch4 as I understand it the new Mirrorview SRA 1.4.0.15 you refer to is only compatible with vSphere and SRM 4.0?
Can someone comment on this / provide clarity?
Thanks,
Craig.
Yes it is... Just found the following - could be of use to others, here is the link for EMC's release notes for Mirrorview SRA 1.4.0.15.
If you don't have access then get in contact with your local EMC rep and ask why?
Thanks,
Craig.
Just tried that link. Logged in with my PowerLink login and got...

Wow, I'm really surprised about that, normally when I post these links they are good
Seriously, only because its you Mike I've enclosed the file below (this is from a Northerner from Cleethorpes living in Melbourne, Australia).
Cheers,
Craig,
I reckon the link is good, but my powerlinks is bad.
I'm not a customer. One thing that irratates about some vendors sites, is their logons don't always expose ALL the docs that available.
Ironically, I'm able to download PowerPath for VMware, but I'm not allowed with my powerlinks login to download the docs. Go figure...
