Environment: Veritas NetBackup 7.6.0.2 running on windows 2008. NDMP backup/restore is done for EMC VNX.
Issue: While trying to restore the data from the tape, we receive the following error. There were many restores successful in the previous instance. This is the first time we face this issue.
Error ndmpagent(pid=2644) EDC-FS2: Specified record size (262144) is bigger than readWriteBlockSize (65536), please refer to Celerra document on how to increase param PAX.readWriteBlockSize
On the media server, when the backup happened the \netbackup\db\config\SIZE_DATA_BUFFERS_NDMP value was 256KB and 64KB in VNX param PAX.readWriteBlockSize respectively.
When the restore failed, we changed the \netbackup\db\config\SIZE_DATA_BUFFERS_NDMP value to 64KB to match the VNX param. However it still fails.
One option is to change the value on the VNX to 256 KB. However the DataMover will require a reboot and there will be a 10 minutes downtime which is not feasible solution as of now.
Question: Is there any way where we can have this figured out within NetBackup level as the restore is on hold because of this error.
