Delete from File uses the exact same .csv file that Import From File use.
Ensure that you export device information to a CSV file. The CSV file with the inventory data is saved at the following location: NMSROOT/files/inventory (in case of Windows) and /opt/CSCOpx/files/inventory (in case of UNIX). Edit the CSV file, so that it contains the devices you want to delete from your network.
Either use the GUI or the CLI script:
NMSROOT/bin/perl deleteDevice.pl -[option] filename -u username - p password
Where option:
s Suspend the devices
d Delete the devices
Where:
filename Valid CSV filename that contains the list of devices to be deleted. Only CSV file is supported.
username CiscoWorks server username.
password CiscoWorks server password.
