Managing 2/20 in San with LINUX

[Marino Meloni_1]

I have a problem with a library 2/20 conected in fc throught a brocade to a netserver running Linux RH 7.1
the library is discovered but the pisker cannot be managed,
start UMA interface
we can manage the drive with tar and rewind drive

run command /usr/omni/bin/uma -ioctl /dev/picker and we can see the slot free and one drive loaded with
catridge

we cannot load or unload catridge or move picker with uma command >>movemediumfailed: [2] no such file
or directory
any idea ? seens config problem

Try using the mc command to see if the problem is with the uma command or if there is something else wrong. Some of the mc commands are to check out the library are:

To display status of drives and slots:
# mc -p /dev/picker -r DS

To move tape from slot to drive:
# mc -p /dev/picker -s S# -d D#
where # = drive/slot number

To move tape from drive to slot:
# mc -p /dev/picker -s D# -d S#
where # = drive/slot number

To display vendor, product and revision info:
# mc -p /dev/picker -q

hi Curtis,
are these command available also if library is conected througt Fibrer Channel, or only with direct connect on the scsi bus?
