EMC Celerra
This information is provided to help you use NetBackup for NDMP with an EMC Celerra Network Server.
Documentation
For more information on your Celerra Network Server, refer to the Celerra Network Server Version 5.5 Documentation CD, which can be downloaded from EMC's Powerlink website.
Tips for control and configuration:
After logging on to the Celerra Network Server Control Station, you can use the following commands:
nas_version
(Displays the Celerra version number.)
server_devconfig
(Queries the device configuration of the specified data mover.)
Make sure that the backup is created from a snapshot. See the following section:
Tips for robot and media discovery:
Check that each Data Mover is recognizing the robot/media devices by entering the server_devconfig command from the Control Station.
For example, the following command queries the device configuration of the specified data mover (server_2).:
server_devconfig server_2 -list -probe -scsi -nondisks
Example output:
server_2 : SCSI non-disk devices : chain= 0, scsi-0 symm_id= 0 symm_type= 0 tid/lun= 15/15 type= disk val= -99 info= 52658653C310 diskerr= -1 chain= 1, scsi-1 symm_id= 0 symm_type= 0 tid/lun= 15/15 type= disk val= -99 info= 52686043C320 diskerr= -1 chain= 2, scsi-2 : no devices on chain chain= 3, scsi-3 symm_id= 0 symm_type= 0 tid/lun= 0/0 type= jbox info= HP C5173-7000 3.04 tid/lun= 1/0 type= tape info= QUANTUM DLT7000 2560q` tid/lun= 2/0 type= tape info= QUANTUM DLT7000 2560q`
EMC Celerra logs are located on each data mover. For example, to access the server_2 data mover log file, enter the following at the Celerra Network Server Control Station:
server_log server_2
Known restrictions
The user name used with the tpconfig command must be defined as ndmp for each data mover.
While tar, dump, and vbb are all supported data types, Veritas recommends the use of dump or vbb instead of tar. Refer to the following tech note for more information:
If you specify an incorrect path name in the NetBackup policy's Backup Selections list (file list), the entire backup fails with status code 99, "NDMP backup failure."
