General Procedure

If a problem occurs, the first step is to try to establish whether the problem lies with the cartridge,
the drive, the host computer and connections, or the way the system is being operated.
Has the system just been installed?
There could be an installation problem:
1. Check through the information in the relevant installation chapter of this guide.
2. Has the system booted? If not, check that all hard disks are correctly seated in the hard disk
bay and then check the cabling between the disks and the SAS controller.
3. Does an error appear during the boot sequence about a change to the RAID configuration?
This error only appears if you have used the supplied cable to replace an existing SAS cable.
Check the cabling between the disks and the SAS controller. If the problem persists, you
have probably disconnected a hard disk drive bay that was in use. See
cable to port on host SAS controller and replace existing SAS cable (page 20)
information.
4. Has the system booted but the operating system has not seen the tape drive? Check that
the drive has power, the READY light should be illuminated. If it is not, check that the power
cord is connected correctly to the tape drive. If READY is illuminated, check the cabling
between the tape drive and the SAS controller. Ensure that the HBA port to which the drive
is connected is enabled. If an external drive was powered on after the server, power cycle
the server.
5. Are appropriate Tape drivers and HBA drivers as well as supported application software
installed on the host?
6. Check the environmental conditions against the specified limits.

Are you using new cartridges or a different brand of cartridge? Have you been using the
particular cartridge for a very long time?
The problem could lie with the cartridge:
1. Check through the media information in
2. Check that you are using an Ultrium cartridge. Compatible media can be recognized by the
Ultrium logo, which is the same as the logo on the front of your drive.
