NDMP config for NS480 to Netbackup 6.5

Question

don't know if anyone here has experience setting this up but I can't figure out the robot path.

I think everything is in place, DM2 is zoned to the 2 tape libraries and it can see both robots and 4 tape drives (2 per robot)
I can also run set_ndmp_attr -probe server_2 from the netbackup master server and it lists all robots and drives

et_ndmp_attr -verify server_2 also came back clean

I tried using the tpconfig command to add the robot but I don't know what the path should be

this is from the netbackup doc

The robpath variable is a non-NDMP Windows device path for
robots. Use it in the {p,b,t,l} format: p is the port, b is the bus, t is the target,
and l is the lun. You can find this information in the registry.

for my robot the device name is c32t0l0, when is bus=32, target=0, lun=0
what should the port # be?

Thanks!!

I am not sure whether you had made any configuration steps on the NAS Data mover side apart from zoning it to the Tape library.

You need to create the "ndmp" user on the data mover - login as nasadmin and then change to superuser mode by "su" (do not use "su -") - run the command to add the user to the DM2

# /nas/sbin/server_user server_2 -add -password ndmp

Set the ndmp user password which will be used by the Netbackup configuration.

Considering the AUX port link speed and any required parameters are set - you then need to create the device file for the tape devices on the Data Movers -

$ server_devconfig server_2 -list -scsi -nondisks
$ server_devconfig server_2 -probe -scsi -nondisks
$ server_devconfig server_2 -create -scsi -nondisks
$ server_devconfig server_2 -list -scsi -nondisks

You must be able to see the tape devices on the data mover along with their ctl number which can be used on the Netbackup configuration.

Please refer to the " Configuring NDMP Backups on Celerra" document available on Powerlink for all required steps and details - which also includes the required steps and configuration on the Symantec NetBackup software under the following Navigation path or below-mentioned link -

Hope this helps,

thanks Sandipfigure it out, there was a very cryptic option in Netbackup that scans in NDMP devices in the add storage wizard..but I still don't know how to perform an actual backupas in what I should put in the backup selection?

jiliu2,What kind of performance do you get with your backups? How many MB/sec?

jliu2 · Answer

turns out the path was just the mount point of the file systemdon't know if this is accurate but I ran a backup test to a single drive on one of the C4sand netbackup reported an average of 33MB/sec
