USCSICMD ioctl calls for Fibre Channel(FC) devices on Solaris 10?

Hi ,

I have wrtitten a C program that issues USCSICMD ioctl call to the tape devices attached on solaris sparc 10. I was able to get the required information from all SCSI tape devices attached using the utility. But, whenever it is run on FC attached tape drives , the program returns an error saying "Inappropriate ioctl for device".

bash-2.05# inquiry /devices/pci@1f,4000/fibre-channel@2/fp@0,0:devctl
inquiry: /devices/pci@1f,4000/fibre-channel@2/fp@0,0:devctl: scsi inquiry failed: Inappropriate ioctl for device

Is it possible to make an USCSICMD ioctl on FC attached tape devices ?. Can someone please provide an example if possible.

Thanks,
Naveen

NAME
jfca - JNI Fibre Channel Adapter (FCA) Driver SYNOPSIS
SUNW,jfca@pci-slot DESCRIPTION
The jfca host bus adapter driver is a Sun Fibre Channel transport layer-compliant nexus driver for the JNI FCX-6562-L and FCX2-6562-L adapters. These adapters support Fibre Channel SCSI and IP Protocols, FC-AL public loop profile, point-to-point, and fabric connection and Fibre Channel service classes two and three. The jfca driver interfaces with the Sun Fibre Channel transport layer to support the standard functions provided by the SCSA interface. It supports auto request sense and tagged queueing by default. The driver requires that all devices have unique hard addresses in private loop configurations. FILES
