I read that SVM-DR relations can preserve volume MSIDs which allows NFS file handles to remain valid in a disaster recovery scenario without the need to re-mount. I tested this with a AFFA300 running 9.1P1 and RHEL VM using NFSv3. Confirmed the msid-preserve is set to true. Performed a SVM DR failover from one site to another site the unix mount froze and was not able to recover unless a lazy unmount was performed. Is there mount options that need to be added or is this only for NFSv4?
