Adding tape drive in Solaris

Verify wether the array controller drives can be seen
# cd /dev/rmt
# ls
0 0cbn 0hn 0m 0u 0b 0cn 0l 0mb 0ub 0bn 0h 0lb 0mbn 0ubn 0c 0hb 0lbn 0mn 0un 0cb 0hbn 0ln 0n

using this command, you can see some drives being specified as 0, 0*, 0** and 0***

Note: * is recognized as some character.

FTP the SAN driver SAN_4.4.9_install_it.tar.Z
# uncompress SAN_4.4.9_install_it.tar.Z
# tar xvf SAN_4.4.9_install_it.tar
# cd SAN_4.4.9_install_it
# ./install_it

After finish installing the SAN driver then reboot the server using this command
# reboot -- -r

The array controller and media changer can be seen after rebooting the server

# cfgadm -al
Ap_Id Type Receptacle Occupant Condition
c0 scsi-bus connected unconfigured unknown
c0::dsk/c0t0d0 disk connected unconfigured unknown
c0::dsk/c0t1d0 disk connected unconfigured unknown
c1 scsi-bus connected unconfigured unknown
c1::dsk/c1t4d0 CD-ROM connected unconfigured unknown
c1::rmt/0 tape connected unconfigured unknown
c2 fc-fabric connected unconfigured unknown
c2::50001fe1500c7cd9 array-ctrl connected unconfigured unknown
c2::50001fe1500c7cdd array-ctrl connected unconfigured unknown
c3 fc-fabric connected unconfigured unknown
c3::100000e00223a9d1 med-changer connected unconfigured unknown
c3::50001fe1500c7cd8 array-ctrl connected unconfigured unknown
c3::50001fe1500c7cdc array-ctrl connected unconfigured unknown

The channel 2 & 3 can be seen as unconfigured. The next step is to configure it
# cfgadm -c configure c2
#cfgadm -c configure c3

Reboot the server to apply the changes
#reboot -- -r

Load the driver in the system and attach to SAN device instances
# devfsadm -c tape

The array controller and the media changer are configured now
# cfgadm -al

Insert the tape into the slot and test wether it can work
# mt -f /dev/rmt/1 stat
