Convert RAID-0 to RAID-1 on HP ML350G6 with P410i zero memory



I have an HP ML350 G6 with a P410i zero memory RAID controller. As far as I can understand that means I can't expand a current single drive "RAID-0" configuration to a RAID-1 using the HP Offline ACU without installing memory and BBWC. Is that correct?



What makes me think about this is the fact that expanding RAID-0 to RAID-1 should be pretty similar to replacing a failed drive in an already existing RAID-1? So then why can't I expand without memory and BBWC?



Is my best option otherwise to (i) use Ghost to capture the disk, create a new RAID-1 with the existing drive and a new one or (ii) buy memory+BBWC and do it online?



Thanks



Answer



Array transformations are possible, but you need to have a BBWC or FBWC unit in place to do so (offline OR online). You may as well get cache memory and a battery since write performance is very poor without them.



See the HP Smart Array Configuration Utility manual.
