Celerra Replication - VMware

I have setup replication (thanks to the help of those in this forum) and I now have another question. I am about to replicate an iSCSI LUN with a VMware datastore on it. How can I connect the replicated LUN to my VMware host on the other end? I know how to connect it and give the host access, but I am wondering if it will recognize the datastore. Does anyone have any info on this?

while the replication is working the destination is readonly - I dont think ESX like readonly data stores

you could failover or break the replication

or create a writeable snapshot and make that available to the other ESX

I think you have to resignature as well -but I'm not a VMware expert

I know how to failover to make it writable. I just wasnt sure if the VM host would be able to recognize the datastore once I attached it. I am waiting on the replication to complete other wise I would just try it. If you tell that I can do this and that the VM host will be able to recognize the datastore than I will award points.

From what I have heard they allow give you things based on the points you achieve. It's nothing nice, just things like t-shirts and other useless items. However useless, if someone wants points and they deserve them, I award them.

dont get hung up too much on points - its not like they buy you anything

the EMC people that I know answering here do so to help in their spare time - its not like its part of their official job

personally I dont care much about points

I do however appreciate it very much to get some feedback if and how well a question was answered or a problem was solved, so that others can learn by reading here

I will make sure that I gived detailed feedback once I resolve the issue. Thanks for letting me know about the points. I was not sure if EMC was like VMware with their points system.

Thanks for the information. After stopping the replication set, I then issued the necessary commands on the destination Celerra to make the LUN read/write capable. After that, I presented the LUN to my ESXi host at the destination facility. Once that was done, I performed a rescan on the host and it discovered the available EMC disk. I then went into the storage option and added additional storage. It discovered the LUN and the associated Datastore. Once the Datastore was added, I then browsed it and added the VMs to my inventory. VSphere detected that the VMs were from another host and asked me if I wanted to resignature them. Once that was done, I was able to successfully start the VMs. Thanks to all who assisted.
