=== ODM Issue Clarification ===

Added a datafile to a tablespace on instance 2, but the asm diskgroup where the datafile is residing is not mounted in the node 1 (asm1). As a result, accessing the problem tablespace from instance 1 gives the following error:
ORA-01157: cannot identify/lock data file 37 - see DBWR trace file
ORA-01110: data file 37: '+DATA02/tqa01/datafile/tradebeam_data.306'

Mounting the diskgroup in asm1 did not resolve the problem.
Accessing the same tablespace from instance 2 works fine.
