Drive Firmware Mismatch
Use the instructions in your User Guide or in the
Spectra T-Series Libraries Drive Firmware Upgrade Instructions to compare the
firmware level of the new drive to the currently recommended level and
update the firmware if necessary.
Connecting the Cables
Connect the cables according to the guidelines in this section.
Drive Connectivity
The drives in the library can have either a Fibre Channel interface or a SCSI
bus interface.
Note:
SCSI interface drives are not compatible with the T-Finity library.
Fibre Channel drives connect directly to the host using a Fibre Channel
arbitrated loop or fabric, as described in
Partitions Using Direct-
Attached Fibre Channel Drives (all libraries) on page 22
.
SCSI drives are connected using a QIP to provide the Fibre Channel
connectivity, as described in
Partitions Using QIP-Attached SCSI Drives
(T200, T380, T680, and T950 libraries) on page 23
. The QIP acts as a
bridge to connect SCSI drives in the DBA to a Fibre Channel fabric or
arbitrated loop. The terminator for each SCSI bus in the DBA is
installed on the drive’s external LVD SCSI connector.
Keep in mind that all of the drives on an arbitrated loop or SCSI bus must
share the data transfer capacity (bandwidth) of the interface. Having
multiple devices on the same loop can negatively impact the performance
of all the devices.
Important
Always make sure that you have the most current firmware for your drives. Check
the Drive Firmware tab on the Software, Firmware and Drivers page of the
Technical Support portal for the latest supported firmware, as well as important
notifications.
Important
Always download drive firmware from the Spectra Logic website to ensure that the
latest firmware posted by the drive manufacturer has been qualified by Spectra Logic.
