Generating the volume_inventory.html file requires you to log into NRM, and click on reports, then the volume you want to see the report on. Once there you can see a report of the current inventory. This however is unwieldy if you have more than just a few servers to run inventory on.
The report will generate by going to the following url:
You will need to authenticate as a server admin. This can be added in a script through wget.
wget https://yourserver:8009/VolumeStatus/[volume]/INVENTORY2--no-check-certificate --http-user=[server admin] --http-password=[password] --delete-after
replace [volume], [server admin], and [password] with appropriate values eg:
wget https://fakecompany.com:8009/VolumeStatus/SYS/INVENTORY2--no-check-certificate --http-user=.admin.fake --http-password=fakepassword --delete-after
This was done on a NetWare 6.5 sp5. wget can be run from many different types of OS’ including NetWare.
