SRM vSphere issue

cef2lion · ‎01-20-2010

SRM installed in vSphere enviroment. We have two Dell AX/4 SANs. The protected site has 5 luns all with VMs. Dell setup the mirror of all 5 luns. They are in sync. We installed SRM on the protected and recovery sides. We then installed the x86 EMC solution enabler and the EMC SRA.

SRM and the EMC Insight tool are only seeing the third lun of the 5 luns. We setup consistency groups on the san for the luns. SRM and Insight now see the 5th lun and no others.

I have a case open with EMC. They only directed me to VMware. VMware opened a case and did a WebX and saw nothing and suggested going back to the SAN vendor. We have a local VMware tech account manger come out and look. He could not find anything wrong. We spoke with a local Dell tech account manager who is working with the VMware tech account manager. They are planning on visting next week but have nothing to go on. VMware and EMC keep contacting about wanting to close the cases.

I saw a post on the VMware forums last summer that had the same issue. The person never posted back that it was solved. I sent a PM but user has not been on since late in 2009. It was titled "SRM sees only one replicated LUN / EMC AX4-5FC" and posted on March 31, 2009.

Hi Craig

The developer has kindly had a look at the logs (I owe him many beers) and noticed that you have multiple secondary images for each primary image - this is not supported.

It should be a one to one mapping - please see below

"This configuration has 4 mirrors with multiple secondary images and not supported by SRM. Please ask them to correct this."

Alex

Thank you and thank the developer. I will look into getting that corrected. Your help is greatly appreciated.

I looked over the mirrors and don't see the multiple secondary images. Will ask Dell about this as they setup the mirrors. I wonder if the 4 to 1 storage groups from protected to recovery site is causing the issue. I attached an expanded view of the mirror from Navi manger.
