In My environment i have got, one public zoning and three operating systems, oracle enterprise linux, vmware esxi and Oracle enterprise Linxu.
Microsoft Windows server 2008, had his partitions in the public san zoning, it had automatic updates services enabled, and it reboots three days ago and wrote in all disks headers from others operating system the GPT windows style, made it unavailable to others operating systems.
I do not have any valid backups, and right know i wanted to revert it, getting the disks headers back to the original, so that Others Operating systems, like oracle enterprise linux and vmware esxi can read those luns disc.
