Hi -

Is that a 2.4 solution?

I was starting to work on a hotplug interface to get and store scsi wwid's
or serial numbers for use with 2.6.

We need a method that would (ideally) work for all users, so we: don't
hang broken devices, can use other pages (0x80), can use vendor
specific methods, and works for udev or multipath config tools.

We need a black/white list (or config file) for the broken or special
devices.

Have you seen the libsysfs/udev code? We can use libsysfs for common
interfaces to get/set a scsi serial number, and for other common uses of
sysfs such as getting the bus_id, or figuring out if we have a scsi
device.
