sgscan will not find the device if there is no link in /dev/sg for that
device. Get the raw device path for the device from /dev/rmt:
# ls -l /dev/rmt/*cbn
/dev/rmt/0cbn -> ../../devices/pci@1e,600000/JNI,FCE@2/st@1,0:cbn
Then check to see if there is a link for it in /dev/sg
# ls -l /dev/sg | grep "/devices/pci@1e,600000/JNI,FCE@2/sg@1,0:"
/dev/sg/c0t1l0 -> ../../devices/pci@1e,600000/JNI,FCE@2/sg@1,0:raw
If there is no link then you need to get that built before you can use
sgscan.
If it is using targets other than 0-15 and luns 0-1 then you need to
change the parameters for sg.build to the targets and luns that your
devices are using.

Subject: [Veritas-bu] I have figured out how to do Zoning with a Brocade
3250, but cannot get sgscan to show the devices! :(
I figured out zoning on my Brocade 3250, but sgscan is being a royal
PIA.

Everything is there!
root@backup01-dev# sgscan
root@backup01-dev#
I have tried rebuilding the st/sg/etc files several times over, with no
success.
cd /usr/openv/volmgr/bin/driver
/usr/openv/volmgr/bin/sg.build all -mt 15 -ml 1
rem_drv sg
/usr/bin/rm -f /kernel/drv/sg.conf
/usr/openv/volmgr/bin/driver/sg.install
sgscan tape
Any ideas?
