General Procedure
If a problem occurs, the first step is to try to establish whether the problem lies with the car tridge, 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 RA ID 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 co ntroller. If the problem
persists, you have probably disconnected a hard disk drive bay that was in use. See
“Option 2: Connect cable to p ort 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 por t 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 ag ainst the specified limits.
