How to Replace all Hard Disks in ISeries (AS400)
Hi,
I am going to to be upgrading a 9406-270 box running V5R3 from 4-17 GB hard disks to 6-35 and I have a few questions. I'm assuming that I'll do a full save (Option 21) as the basis for transferring my data. Once I've done that, removed the old disks and installed the new ones I won't actually have an operting system in the box anymore so how will I boot it up? ( really basic question there I guess) Once I've got it running how do I restore all of the configuration and data so that I'm back to where I was and lastly how do I level the information across the new disks? I'm grateful for any guidance you folks cans give, Thanks.

Hi Tom,
It's a RAID 5 configuration.
I fully understand your comment on the back-ups being multiple. I guess that means I get to watch the paint dry for several weekends instead of just one. With regard to booting up after the new disks are installed do you mean I'll just have tape # 1 in the drive and boot from that? Are their special commands to boot from tape?

What is your current RAID configuration? There might be alternatives depending on what your current setup is.
The short answer is that your full-system backups contain everything needed to boot and restore. And note that it's plural -- "full-system backups". You _don't_ want to discover a media error while doing a restore from your only copy. Ideally, the backups are done to media from two different vendors. Next best is media from two different serial number ranges because sometimes manufacturing causes inherent errors in serial runs.
