Are your 3590s really FCP scsi drives to the world or are they also accessed by an A20 tape controller? The newest 3590s come as FCP scsi drives, but are attached to an A20 tape controller which presents them as FICON/ESCON drives to the attached systems. You can't access them as native FCP drives, only as channel attached drives through the controller.
If your drives are really stand alone FCP drives then you can probably have them reconfigured to Point to Point mode. The zfcp driver does not support arbitrated loop mode. It only supports point to point switched fabric mode.

We have never been able to get Linux to report the existence of the tape drives in /proc/scsi/scsi. The SAN switch is reporting that the tape drives are using the arbitrated loop topology. The manuals shipped with the drives indicate that arbitrated loop is the default topology. Do we or our field engineers need to do something to reconfigure the drives for the switched fabric topology? ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
