Can IBM DFHSM coexist on the same system as CA ASM2 and what are the requirements?
Yes, CA-ASM2 will work with the DFHSM environment. However IXR should be first in line in regard to the catalog intercepts
(SVC26). Also the pseudo volser for IXR cannot be MIGRAT.
See the CA ASM2 Reference Guide for the optional use of Pseudo volser names that can be used and how to set those up in each CA ASM2 archive process.
See the CA ASM2 Planning and Installation Guide for instructions on the Catalog Locate (SVC26) intercept which is required at install time.
