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
“
Option 3: Connect cable to port on host SAS controller and replace existing SAS cable
31 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 as well as supported application software installed on the host?
