Fibre Channel drives
Before configuring your system to support an HP LTO Ultrium drive, ensure that the drive is visible to
the Sun system HBA by correctly zoning the fabric switch (if one is being used).
Configuring the device files
Before configuring FC-attached drives, ensure the operating system is updated with the latest
recommended patches. On Solaris 8 and 9 you also need to install the Sun/StorageTek StorEdge
SAN Foundation software from www.sun.com/download
(select the Storage Management link, then
StorageTek SAN x.x).
When SAN configuration is complete, verify that the drive is visible to the HBA by typing:
% cfgadm -al
This should produce an output similar to:
...
c3::50060b000xxxxxxx tape connected configured unknown
...
This indicates that the drive is configured and the device files built. In this example
c3::50060b000xxxxxxx is the attachment point identifier with 50060b000xxxxxxx being
the WWN of the drive port attached to the SAN and visible to the HBA.
If you do not see anything similar to the example above, recheck the SAN connections and the
zoning configuration to ensure that the HBA and drive ports are visible to each other.
If the tape device shows as unconfigured, type the following:
% cfgadm -c configure c3::50060b000xxxxxxx
This will build the necessary device file in the /dev/rmt directory.
To verify the particular devices associated with a specific WWN then use the following command.
% ls -al /dev/rmt | grep 50060b000xxx xxxx
Replace 50060b000xxxxxxx with the appropriate WWN for the drive.
SCSI drives
Determining the SCSI ID
Before you configure your system to support an HP LTO Ultrium drive, determine which SCSI ID to
use. IDs must be unique for each device on attached to the SCSI bus.
1. Use the modinfo command to identify SCSI controller drivers installed on the system:
# modinfo | grep "HBA Driver"
