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.

Each raid set needs their own hot spare, right? Or can two raid sets in the same expansion unit use the same hot spare? Because the other raid set in that unit does have hot spare.
Due to financial considerations the new hot spare wasn't ordered until today (12/1). If it doesn't come in before 12/11 I'll have to add it later. Is that an issue?

ESLS expansion unit
All the drive types are listed below

And where is the decoder which tells us what the three digit code after the disk model means?
Based on the current situation I'm going with
5B11-101 = Hot spare
5B11-105 = Non configured
5B11-109 = Raid 5 with hot spare
But that's only a WAG based on the current setup.
