Re: Adding hot spare to an existing raid set.

["Larry \"DrFranken\" Bolhuis" <midrange@xxxxxxxxxxxx>]

As long as reachable from the same set of RAID cards and a suitable 
replacement, hot spares can be shared.

I believe your 'secret decoder ring' is close. You can confirm the 101 
by checking the cereal number to the hot spare.
Non configured should be 099 (non-protected or mirror protected)
The 105 and 109 may have to do with number of drives in the raid set. We 
used to have 074 078 and such in the SCSI days for that.
