Troubleshooting
Problem
"dsmigfs enablefailover" command generates an "ANS9418W - File DSMNodeSet could not be acquired at the moment" error in HSM multi-node clustered environments.
Symptom
The following error messages in the dsmerror.log may be seen when a node fails over, but after the "dsmmigfs enablefailover" command is run:
ANS9418W dsmmigfs: File DSMNodeSet could not be acquired at the moment. It may be locked, or the var filesystem may be full. Will try to acquire the SDR lock again in a few seconds.
These messages may also be seen:

Diagnosing The Problem
