Mirroring DCO & DRL - Windows Failover CLuster
I've got just some questions about DCO and DRL in Storage Foundation. Maybe someone can help ;)
I have a 2 nodes failover cluster (windows 2012) and I use Storage Foundation 6.0.2 to create a Dynamic Disk Group. This dynamic disk group contains 2 SAN disks (these disks are located on remote and separated storage arrays) and the option "Create cluster Group" is enabled.
I create a new volume (mirrored option enabled) and then, I add Log (DRL) & FastResync (FastResync is mirrored beetweend disks)
Sometimes, when a network failure occurs, I have to remove and add again the DRL on the disks which was previously in failure.
This behaviour is explained here.
Ok, now I wonder if I really need to add the DRL on disks ? I have read here that the DRL is built into DCO Version 20.
How can in know which version Storage Foundation uses ? I tried something like vxprint -g name-oft-he-disk-group -F%... but it didn't work.
For your information, here is the failue:
I do apologize for my english.
