Fibre Channel Connections/SAS Connections

This section provides notes on using a Fibre Channel connection or SAS connection to connect the LT260.
(1) Checking the devices
Perform the following procedure to check whether the devices (tape drives) are correctly connected to the
server.
Procedure
1
Log in to the server with the root privilege.
2
Execute the "cat /proc/scsi/scsi" command to display a list of the connected devices.
-
From the above contents, check whether the LT260 controller and drives are recognized in correct
paths and whether the values of the recognized target ID and LUN match those of the LT260 drives.
(2) Setting fixed device file names
When a Fibre Channel connection or SAS connection is used to connect the LT260, the device file name
that is assigned to a device must be associated with a physical device. This association is a fixed setting.
Note that this setting is not required when the device that is being used can be associated by the backup
software, such as NetBackup, NetVault, or IBM Spectrum Protect. For information on whether the backup
software supports associations and for version information, contact the person in charge of the backup
software.
