First, let me explain our situation:
We had an HP server with a RAID 1 over 2 drives (for the OS) and a RAID 5 over 4 drives (for VM data). The raid recently failed. I say the word failed very loosely because to this day I still don't know what exactly caused it. We thought at first a failed drive was the problem. But, after running the HP Offline ACU the status of the drive originally thought to be failed is indeed showing no errors. However, we have another drive (which originally didn't show any errors) now showing a warning that it might fail soon.
Now, here is my question:
Can we see how the raid was configured before and configure it exactly as is and not lose any data? Or are we going to lose data no matter what? The backups we have are not completely up-to-date so I want to try to restore data back to how it was at all costs. I am just not sure if when I recreate the logical volume (exactly how it was) if my data will still be purged?
Is there a command line utility in ACU Offline that will allow me to recreate a logical volume that will NOT purge data if the GUI will?
Thanks for your advice.
