Re: Change Raid Settings

DC01 controls 8 drives, OPT01 (I know what that is), and D01,D02 (don't
know what those are)
DC02 controls OPTVRT02, OPTVRT04, and TAPVRT01
DC03 controls nothing
DC06 controls 8 drives and D03, D04 (again, don't know what those are)
DC04 controls nothing

Jeff, if you "9=Work with resource" in front of each of the "DC*" you'll
quickly find out which one(s) control your disk drives.

Bear with me because I'm not much of a hardware guy.

Here's the WRKHDWRSC TYPE(*STG)

Yesterday we had a disk failure at 4:27pm, which happens to be 3

before we run our entire days business. Good timing, eh? We ran
everything and then replaced the drive and rebuilt the RAID. I

honestly

don't remember the last time we had a disk failure before this.

Our System i 520 is on i 7.1 and has 16 drives in it. There are 2

RAID

sets with 8 drives each. Disk utilization is less than 19% so we have
plenty of space. (We used to have an IXS way back when, which is why

we're

way over capacity on disk.)

The service guy (ServIT) thought, since we're on 7.1, it might be

possible

to change each of those 8-drive RAID sets to a 7-drive RAID set with a

hot

spare. I questioned him because of the age of our hardware and said

he

still thought it was possible. He's going to look into it today.

Since there are some very smart hardware people on this list, I'm

going

to

ask here. Can that be done? Can that be done without a reload?


Thanks.
