I'm new with Netapp along with SAN Technology, so I apologize in advance.
We have a Netapp SAN, where both controllers failed. We got that fixed, however we are dealing with the fallout from it.
I have a RHEL5 VM managed by vCenter, however we I tried to boot it up, the disks were scrambled and it would not successfully boot up. We are going to restore from backup and then just build a new VM.
Doing some research, I wasn't using UUIDs under /etc/fstab, so that might have been one of the reasons the disks got scrambled.
My question to you all is, is there a way for me to try and figure out how to map back to those disks correctly either from the SAN or from the VM in order to try and rebuild this server?
Also is there a way with the UUID from Red Hat to see what LUNs these point to?
Packaged into the kit is a utility called "sanlun". You can run a command similar to the following to provide you the block device and how it corresponds to the LUN name and WWID in SANtricity or SANtricity System Manager:
The utility will not work for virtual disks mapped to the virtual machine. You may have to browse the individual datastores and look beneath the folder named for the virtual machine that is being blown away and restored. The individual .vmdk files will be named "-flat.vmdk" and ".vmdk". Choose the ".vmdk" to map back to the host, which is essentialy a descriptor file that points to the "-flat.vmdk" that contains the data.
