Hi, I have a Promise R4 that has suffered a the hands of an incompetent and needs to have the logical volume rescued.
The tech ejected all the drives while the system was off, brought it up with new disks and recreated a new array.
I need to revert back to the old array definition, very badly. I have imaged the raw data off the hard drives and am wondering how to approach this.
My thought it to put the new disks in, recreate an array in the same "shape" as the old one, power off, and if necessary overwrite the disks with the images I have. Bring it up, and the partition should be there. Right?
Question: does creating a logical volume or anything else *necessarily* write to the drives? I would sooner it did not write a partition table or format a volume, just update the controller's definition of what the storage array should look like.
