I also run NDMP backups to CelerraDump format stg pools. Do you have access
to the NAS filer?
If so, you can check the NDMP settings
(In our case, on the filer, i need to be in /nas/bin to issue server_param
commands)
./server_param NASNODE1 -facility NDMP -list
Is there anything in there that suggests a timeout threshold?
also:
### To view the value of the NDMP port range, use this command syntax:
server_param {ALL|<movername>} –facility NDMP –info portRange
### where:
<movername> = name of the Data Mover
### Example:
### To view the value of the NDMP port range, type:
$ server_param server_2 –facility NDMP –info portRange
