Tom and Jon, thanks for the great replies. I'm just getting back to this
project again.
I've tried this
amtapetype -f -b 524288 -t IBM-ULTRIUM-TD5 /dev/sg2 2>&1 | tee
tapetype-ultrium-512k-block
and get this
amtapetype: Error writing label 'amtapetype-1614155207': File /dev/sg2 is
not a tape device at /usr/sbin/amtapetype line 93.
I figure I need to define a tape device that includes /dev/sg2? I've added
the changer definition to amanda.conf:
define changer scalar_i500 {
tpchanger "chg-robot:/dev/sg2"
property "tape-device" "0=tape:/dev/sg2"
}
tpchanger "scalar_i500"
But am getting the same error. I've also tried
amtapetype -f -b 524288 -t IBM-ULTRIUM-TD5 scalar_i500
and get
amtapetype: Error writing label 'amtapetype-1739790301': Can't open tape
device scalar_i500: No such file or directory at /usr/sbin/amtapetype line
93.
mtx works fine on /dev/sg2. Any suggestions? Thanks.
