The option in NV 9.x that was previously displayed when doing a 'Configure' on a drive as "Time between polling empty drive [0=never] (mins)" is no longer available via the NV 10 WebUI's tape drive configuration options.
Workaround:
Open the NV 10 drive template file located at:
'..\NetVault Backup\devices\drives\drives.tpl'
There is a stanza in that 'drives.tpl' config file showing:
-------------------
[Device:Poll Empty Drive]
Tab Name = Configuration
Label = Time between polling empty drive [0 = never] (mins)
Type = Range
Range = 0,1440
Width = 5
Value = 1
-------------------
This is where the *default* setting for the polling would be set when adding any *new* drives.
To change the polling time for a tape drive, modify the 'drives.tpl' config file's Poll Empty Drive "Value = 1" variable to the number of minutes to the desired number, which would be to '0' if the preference would be to 'never' poll, then save the modified file.
Then 'Remove' each of the existing drives from Manage Devices and re-add them again so that the updated poll value is applied to those newly re-added drives.
