We have an external HP array with it's controllers in two servers. Once of the servers has an array of 6x72GB drives, one of which has failed. Rather than replace the failed 72GB drive, my client wants to purchase 4x300GB drives to give them more storage for their autocad drawings. My question is if I replace the 6 72s with 4 300s, will the existing configuration freak out or will it simply adjust to the new disk? Or do I simply delete the current config and create a new one for the larger drives? This array contains no boot partitions. Data can be restored from backups.
