Unit XX With Device Parity Protection not operational?

Hello:

This morning, our AS/400 popped up a series of messages that looked like
this:

Unit 25 with device parity protection not fully operational.

This message was repeated for units 25, 26, 27 and 28.  Afterwards, another
message popped up that stated:

Units with device parity protection fully operational.

Does anyone have any idea what the "units" are?  Are they disk drives?  It
has me a little worried since our UPS failed and we have been without one
for several weeks, now.  We are still waiting for a new one.  We are using
an S30 model running V4R2.

I would appreciate any information.

Thank you,
