Re: Quick Question on Raid5 w/Hot Spare

[Jerry Draper <midrangel@xxxxxxxxxxxxx>]

With older controllers you can run into this situation:

We had one hot spare and to protect the load source drive it has to be 
in a load source capable position.

We lost a drive (not load source) and the hot spare activated taking the 
place of the dead drive.

Now we were in a tricky position.

Just replacing the dead drive meant that our load source drive would not 
be protected by the hot spare system.

We had to plan for a machine power down to move the drives around so we 
could end up with our hot spare in a load source capable position.
