Hi Guys
I am trying to do something clever for our disaster recovery site, we mirror our ESX Volumes using our SAN technology and i have managed to script presenting Views of the latest mirror PIT to the remote ESX cluster, i have been toying with Powershell to automate an HBA rescan for the whole cluster, but i was wondering if anyone knows of a way of automatically discovering and adding VMs from the presented datastores to vCenter? I am running ESX 3.5 update 4 and vCenter 2.5 update 5, still evaluating vSphere but if there is a better way with vSphere4 let me know it will help my case to go live sooner
thanks in advance.

I suppose that in the DR site you have a single ESX...
In this case, after you have do the SAN stuff (to see the replicated VMFS datastores) you can do something similar (is just an example...):
for VMX in /vmfs/volumes/DataStoreName/*/*.vmx do vmware-cmd -s register $VMX done echo "Registered VMs:" vmware-cmd -l
You can also use vmware-cmd to power-on the VMs.

I am busy working on a PowerShell script that should process a failover for you, if you are replicating the VMDKs using 3rd party replication - I will post it on the community when I am done - so I can use all of your production environments as my test bed . .
I'll keep updating it until I get more positive feedback than negative feedback :smileydevil:
basically my DR setup has 4 SAN attached ESX servers in a cluster, i mirror 8 luns that contain about 100 VMs.
My SAN script takes a View on the latest PIT (point in time snapshot) and presents it to these 4 hosts.
I can use the PowerCLI to issue a rescan
get-vmhost | get-vmhoststorage -rescanallhba
this should make the datastores all pop in. (vmfs1,vmfs2,vmfs3 etc)
it i use the PowerCLI
$vmxpath = get-datastorefiles (get-datastore vmfs1) |
where { $_.Path -match '.vmx$' } | select path | % { Register-VM $_.Path
-vmhost (get-vmhost dresx.company.com) }
is there a way to register a VM to a cluster rather than a host?
