I have P410i+256M Cache without battery backup. My RAID5 was build over 3*136GB disks, now all disks were replaced to a 3*300GB array.
How can I extend it to use the whole space?
HPacucli doesn't allows that, I think this might be because no battery is present.
I have a redundant power supply. All data is mirrored over DRBD to a secondary server, so I can try to resize with a chance of loss of data in case of power failure, but I prefer to have an online resize.
