>Description:
ccdconfig gets ENXIO for BOTH unconfigured ccd device AND unconfigured
disks.  The errno and the way it is printed leads you to believe that
the ccd pseudo isn't available when actually it's the disk you're trying
to put in the ccd (I had name slippage when moving scsi disks around).
>How-To-Repeat:
# # ccd4 is MAKEDEVd but not in kernel:
# ccdconfig ccd4 128 0 /dev/sd3a
ccdconfig: open: /dev/ccd4c: Device not configured
# # ccd3 IS configured by sd3 is not
# ccdconfig ccd3 128 0 /dev/sd3a
ccdconfig: ioctl (CCDIOCSET): /dev/ccd3c: Device not configured

>Fix:
ccdconfig.c do_io should distinguish between the open fail and the ioctl
fail with ENXIO and make it clear what it applies to.
