Hi All,
I have been having intermittant issues with the QLGC,isp driver
(qlogicpti.c) not finding any attached devices on my sun4c. Having now
moved on to Linux-2.6.22 this problem is now also affecting the ESP SCSI
driver and is nolonger intermittant.
My test setup uses an NFS root so it is currently independent of the SCSI
drivers/subsystem. I am hoping to change this in the near future so that
my sun4c boots into linux by default.
What kernel options can I use to try to work out why the drivers are
ignoring disks (there are no other types of attached device at present).
Are any special options needed to force the scsi subsystem to spin the
disk up and wait untill they become ready (The disk [target 0:0:3] on the
ESP auto-spins down if it is idle for too long and now that booting takes
longer ...) ?
Is there a way to get a NON-moduler scsi driver to re-scan its SCSI bus
from shell prompt (writing to a sysfs/procfs file)?
From my point of view, it looks like the command timeout is very much too
short. Is there a simple way of testing this theory on the ESP driver?
Regards
Mark Fortescue.
