DLT 40/80 GB Drive Goes Offline

[Dan Valenti]

I had an issue today where my internal dlt 40/80 gb tape drive goes offline and the backups fail. I check the event viewer and seen error about failed to load qic117 becasue device does not exist. I dont know why this driver loads cause its disabled in the devices in the control panel. I updated the bios on the server , updated bios on the raid card and rebooted server. After rebooting the server everything seems fine but i see a new error in the event log stating this:
The following boot-start or system-start driver(s) failed to load:
cdlt8n4i

I dont knwow what this is and why it failed. I also would like to know if there is a way when a drive goes offline to bring it back on line without rebooting.

Any help will be appreciated.

Dan,
it's not recommended to connect tape devices to RAID controller. Please use HP recommended HBA from the list at http://www.hp.com/cposupport/information_storage/support_doc/lpg50063.html .
You also may download HP Library and Tape Tools from http://www.hp.com/cposupport/information_storage/support_doc/lpg50128.html and diagnose your drive
