DFS3454I I/O ERROR READING RESIDENT DIRECTORY ($$IMSDIR) `ddname` {-`nn`}

Explanation
 An I/O error occurred while the /MODIFY
COMMIT or INITIATE OLC PHASE(COMMIT) command
was reading the resident directory ($$IMSDIR) member from the inactive
FORMAT library. If the error occurred on a FORMAT library that has
concatenated data sets, nn indicates on which of the concatenated
data sets the error was received. ddname is the
name of the DD statement for the library for which the I/O error occurred.

System action
 The command is ignored.

Programmer response
 Recreate the resident directory ($$IMSDIR)
on the inactive FORMAT library. Copy the $$IMSDIR member from the
active FORMAT library to the inactive data set, and the updates then
reapplied, using the MFS Service utility.
