Hello !
I was wondering if anyone could give me advices on how to handle storage access failures for VMs.
For exemple, we have a iSCSI storage array located on datacenter 1, and VMs accessing it from datacenter 1 AND another datacenter, datacenter2.
We had a network outage between datacenter1 and 2 that caused issue inside a windows file server guest VM (all previous version VSS snapshots lost/corrupted).
How could I handle this in future ?
I know I can increase the disk timeout inside windows guest ( vSphere Documentation Center ) but would that be egnouth ?
Do I have to increase timeouts too in VMware ESXis ?
What I try to achieve is data consistency over service availability.
By this I mean if I could find a way to "auto-freeze" all VMs that need access to storage with APD condition, either with a SUSPEND command directly sent to the VM or freezeing the VM world on the ESXi.
So the VM would be inaccessible but would not fail data i/o until the storage is accessible again.
Thanks for any hints
