General Procedure
If a problem occurs, the fi rst 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 con fi guration?
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
“ Option 2: Connect cable to port on host SAS controller and replace existing SAS cable ” on page 28
for more 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 speci fi ed 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:
