We have a running RAC cluster on a VM which is based on Raw Disk mapping and shared across data centers. This is a stretched cluster across two data center. Recently we had one site the SAN storage , VM and Network was down. The services fail over happend successfully but we saw that the ACFS diskgroup and ADVM went into a unknown state.
We tried to reboot the server but then realized that VM was unable to start the VM since it was looking for disks mapped from the Data center 1 SAN. All the disk were shown as Dead.
