Installation Problems
Problems encountered during the installation of the library are usually caused by
improper SCSI bus configuration, application software configuration errors, or an
incorrectly configured operating system. If the application software that you are
using is not communicating with the library after installation, check the following:
v
Accessor Ship Lock Key:
Ensure that the Accessor Ship Lock Key on the top cover has been removed
before
powering on the library. Refer to “Removing and Storing the Shipping
v
Drive SCSI or Loop ID:
Ensure that the SCSI ID of the Drive (or Fibre Channel Loop ID) is correct and
not the same as other devices that may be on the same bus or loop. To
determine the SCSI or Loop ID for each SCSI or Fibre Channel drive in your
library, navigate to:
– Operator Control Panel: Monitor > Drive > Identity
– Web User Interface: Monitor Library > Drive Identity
To change a drive's ID, navigate to:
– Operator Control Panel: Configure > Drive > Drive Interface
– Web User Interface: Configure Library > Drives
v
Host Bus Adapter (HBA) Compatibility:
Ensure that the library is compatible with the HBA. For best performance, the
HBA used for this library should be SCSI-3 LVDS. Pay particular attention to
any steps describing settings of various jumpers and/or switches.
v
HBA LUN 0/1 Support:
A single ID will address both drive and library since the drive is LUN 0 and the
library is LUN 1. These models require an HBA that supports LUN scanning
which must be enabled at the HBA. Refer to “Logical Unit Number (LUN)
Scanning” on page 3-7.
v
Cable Connections:
Ensure that there are no bent pins on cables and that all connections are securely
fastened.
v
Fibre Channel Tape Support:
Ensure that Fibre Channel Tape Support is enabled on the HBA if you are
installing a library with a Fibre Channel drive.
v
SCSI Cable Length:
Ensure that the maximum cable length is not over 25 meters (82 ft.) for a single
device on the bus or 12 meters (40 ft.) for multiple devices. Internal SCSI length
within the library accounts for 2 ft.
v
SCSI Termination:
Verify proper termination on both ends of the SCSI bus. Refer to “Connecting
the Host Interface Cable” on page 4-16.
v
SAS Cables
Ensure that SAS Cables are properly attached. Refer to “Connecting the Host
Interface Cable” on page 4-16.
v
Backup Application Installation:
Refer to the documentation included with your backup application software for
instructions on how to verify proper installation.
v
Device Driver Installation:
