failed to configure DD tape library (VTL ) in netbackup
Dear All,
We are failed to configure DD tape library in netbackup below are the details
DD is published & configured as VTL tape library on master server & it also a robotic host for the same
the same tape drives are zoned to one of media server named as hydt5440-nbmed1 but here i could not configure this library either through wizard or command line
Wizard error
Unable to determine robot type.
Drive is standalone or in unknown robot.
The robot drive number for this drive is unknown.
tpcommand logs are attached with verbosity 5
What i came to know about zoning w.r.t. DD as VTL is only changer is enough to publish all tape drives on destination server. no need to zone robotic path as it used to be in physical tape library
Still confused about this theory on DD
Currently everything is working on master which is robotic host please suggest
Master serer - Solaris / 7.5.0.6 ( robotic host for that VTL library )
Media serer - Solaris / 7.5.0.6
devfsadm sgbuild & everything is performed on media serer
On the + side, scan works so in theory, NBU will configure drives now via the device wizard (be sure to select both the media serevr vand the robot control host at the same time).
On the negative side, 102 tape drives will be interesting ... Things might not even work correctly with that number.
That will put an unnecessary load on N NBU (it has to monitor all these drives) and as Revaroo says, you can't use 102 drives at once, max should be around 10 (though you can probably only write to less than that at the same time at full speed, due to the limits of the OS/ H/ware of the media server).
