SVC, StorWize, FlashSystem, Spectrum Virtualize – replace a drive

I always forget, so here’s a reminder…

When you replace a drive on one of these, mdisk arrays do not auto-rebuild.

If the GUI fix procedures go away, or never show up, or whatever causes the replacement drive to not get included as a new drive in the mdisk, you can do this manually.

First, look for the candidate or spare drive you want to use.

Then, make sure that drive ID is a candidate:
chdrive -use candidate 72

Then, find the missing member:
lsarraymember mdisk1

Then, set the new drive to use that missing member ID:
charraymember -member 31 -newdrive 72 mdisk1

You can watch the progress of the rebuild:
lsarraymemberprogress mdisk1
