VERITAS Volume Replicator (VVR) - /usr/sbin/vrstat is not printing statistics

Resolution
The above issue can occur since the migrate operation results in RDS (Replicated Data Set) information getting updated on both primary and secondary side vradmind. After multiple migrate operations, stale handle to older RDS is used by vrstat to retrieve statistics resulting in the failure.
Restart the vradmind process to reinitialise the vrstat and vradmind associations:
# pkill vradmin; sleep 5; /usr/sbin/vradmind If restarting vradmind does not resolve the issue, then please contact Veritas Technical Support for further assistance as code changes have been made to ensure correct and updated RDS handle is used by vrstat to retrieve statistics
