Hi all,

I'm working on a IMS V7 system. My IMS databases are reside on R2 part of a mirror system.

for "SOME" databases, I cannot open databases via CICS or my online jobs and the error is for example:


DFS0730I UNABLE TO OPEN DATA SET WITH DDNAME RETIBRAN FOR REASON C, +
94, DATABASE RETIBRAN PSB FCSBT030


when I move the "INDEX" of database to a non-mirror DISK and stop/start the IMS engine, the database
opens correctly with no error !


Could anyone help me to solve this problem.
Thanks in advance,

Mehrdad
