Hi,
I have VMs running in ESXi 4.0 managed by vCenter Server.
These VMs have one virtual disk connected to a non-shared SCSI controller, and a set of shared (via SCSI "virtual" bus sharing) virtual disks set as independent/persistent.
The "Take snapshot" function is greyed out for these VMs, no matter whether they are on or off. I guess it is due to the shared disks/controllers?
Why can't I take a snapshot, as all the shared disks are "independent" anyways?
Is there any possibility to allow a snapshot, maybe through the API, to get around the vCenter logic that does not allow to take a snapshot of these VMs?
Thanks
Klaus
I did some testing with this, after setting up an oracle RAC poc environment. Once you set the second scsi controller in a clustered set up to shared mode, you lose the ability to do any snapshots. I validated this with a windows vm as well. The behavior is the same.
It looks like our oracle dba's will just have to be careful when they do the install!
Hi,
Once you change the SCSI bus sharing to Physical or Virtual you wont be able to take snapshots of that VM. And I dont think there is some way in which you can take a snapshot of VMs with shared disks.
