Hello,
I'm using VSA and RemoteCopy to test a DR/BC implementation using VMware and LeftHand Networks SANs.
The Volume Failover/Failback Wizard has instructions for disconnecting Windows based iSCSI sessions. Do you have instructions on how to do this with VMware without shutting down the entire VMware server?
Thanks,
Ed

Hi Ed,
Within VMware it's a relatively simple process (Make sure your VMs are off of the datastore prior to doing this)...
1) Login to your host or VCMS using the VI Client
2) Select the host that you want to administer
3) Select the "Configuration" tab.
4) Select the option for "Storage" which will list your attached datastores. Select the datastore that you no longer want and click "Remove".
5) Once you have removed the datastore, go to the "Storage Adapters" option, select the appropriate iSCSI adapter (either HBA or iSCSI initiator). You should now see a LUN in the Detail window that co-responds with the datastore that you removed and it should say that it is "DEAD".
6) Click "Properties" in the Detail window.
7) In the Properties window, click either the Dynamic Discovery or Static Discovery tab (whichever you used to find your iSCSI target) and you should see the corresponding target IP/Name. Select the target and click 'Remove'. Close the window and then click the "Rescan" option in the upper right hand corner of the Storage Adapters window and you should now see no instances of the target or datastore. If you go back to the CMC, you should see that the iSCSI sessions for the volume are now disconnected and you can work with the volume as you see fit.
Let me know how that works or if you have any additional questions.

I'd also add that I considered it a bug in the UI that it did not allow you to continue through the wizard anyway.
I think that is getting changed in our next service pack. I'll go double check that.
In the meantime you can manually do exactly what the wizard is trying to help you with and then the current iSCSI session will not prevent you from finishing.
Please try just using remote copy to copy back the new snapshot to the volume that used to be the original.
I don't have the UI in front of me to try and give you exact steps right now though. I'll try to get around to that.

Thank you both for the information.
I'm a bit concerned about step 4 in Tyler's e-mail about removing the datastore. When I go to remove the datastore, I get a "Confirm remote datastore" dialog that warns that "This operation will permanently delete all files associated with the virtual machines on this datastore". I'm pretty sure I don't want to do this.
Any comments?
