If after installing a new drive in a raid, you get a message that looks like this:

//server> info c10

Quit tw_cli and run this from the command line:

[~]# ./tw_cli sched rebuild c10 enable

The raid should then start rebuilding immediately.

I think you could also run this from inside the tw_cli program, but I didn’t try it.

/c10 set rebuild=enable
