Subject: qla2xxx: does not respond to SCSI_IOCTL_PROBE_HOST
Date: Wed, 24 Aug 2005 15:34:15 -0500 [thread overview]
Message-ID: <1124915655.13251.16.camel@localhost> (raw)
Hello, all.
Here's the situation. I am running a QLogic QLA2200 (32-bit mode; lspci
output follows), and when I issue an ioctl() to call
SCSI_IOCTL_PROBE_HOST to /dev/sg0 (example code follows as well), the
ioctl() returns 0, as if to imply that there is no host present, which
is obviously not possible since the drive is attached to the HBA. Using
an Adaptec 29160 adapter with a drive connected produces logical,
reasonable output, so I'm turning to the experts here. Is this by
design, a bug, or just something I've horribly missed? I have tried it
with a 2.6.11 and 2.6.12.5 kernel to no avail.
Thanks,
Drew Winstel
