Not really, no. :-)

No.
The '88' most likely represents a z/VM system in the vicinity. I don't know if
MVS uses the same value. DS QD,QHA may give you a better picture.
The '00' in the middle isn't meaningful.
The last two digits are the partition identifier, a concatenation of the
logical channel subsystem (CSS) number and the MIF ID within that CSS.
The z/VM QUERY DASD DETAILS command uses the same data to produce something
like:
HOST ACCESS: CPU PARTITION GROUPED RESERVED MPATHMODE
7D48 26 Y
N Y
-LOCAL D6D8 17 Y N
Y
EE58 3E N
