Hi Ken,

Thanks for the advise.

Actually, the problem was a bad terminator which caused SCSI bus which was
connecting Library Controller to FibreChannel bridge to malfunction, so
actual controller was not visible on FibreChannel.

Now I`ve fixed problem and here is how correctly connected Library looks
like:

ch0 at isp0 bus 0 target 129 lun 0
ch0: <HP C7200 1720> Removable Changer SCSI-3 device
ch0: 100.000MB/s transfers
ch0: 19 slots, 1 drive, 1 picker, 1 portal
sa0 at isp0 bus 0 target 129 lun 1
sa0: <HP Ultrium 1-SCSI E32L> Removable Sequential Access SCSI-3 device
sa0: 100.000MB/s transfers
pass2 at isp0 bus 0 target 129 lun 2
pass2: <HP C7200 FC Interface 009t> Fixed Storage Array SCSI-0 device
pass2: 100.000MB/s transfers

<HP C7200 FC Interface 009t>       at scbus0 target 129 lun 2 (pass2)
