Replicated resources not avaiable after fail over

Hello All,

I have two Dell Unity 480F, one is at a remote site. I have asychronous replication configured

for a VMware datastore that contains 3 test vm's. If I understand correctly, a failover with sync should allow

a failover to the remote site, and the replicated resources should be available. The virtual machines din the replicated storage were not accessible. I did no do a "resume" on the remote site.

I then decided to do a failback (to the main local storage) - this worked, but only two of the 5 virtual machines were accessible. I had to shutdown the vm's and then restart - then I could access the machines.

Am i missing something here? What is "replication" supposed to do?

Thanks,

Eholz1
