I believe IBM's use of MTTR for the address of a record on disk goes back to
OS360 and HASP. Not exactly new.

JES2 SPOOL addressing uses 4 byte MTTR where
M is SPOOL extent number
TT is track address (up to 64K)
R is record number
Why does IBM always do that?
Why do they continue to confuse us by appropriating other anacronyms
and re-using them?
I remember when an electonics engineer was in an IMS course with me
(circa 1981), and he was continually getting confused about PCB.
Programme Control Block
Printed Circuit Board
And, they have done it over and over again.
The term they 'steal' is usually a well-established and understood
term in another discipline.

Unfortunately Ted didn't take sufficient account of the qualification
in your Subject line.
I know of no other meaning for MTTR.
I have been involved in availability and other service levels for 26
years.
If there is another meaning, please enlighten me.
I did state that my version of MTTR did apply to more than just JES2
(or even just IT).
