Hello,
I was using removable hot plug discs on a O2 running Irix 6.3.
On this system, devices, once created, stay under /dev/dsk /dev/rdsk and
/dev/scsi.
With this kind of behavior, I was able through macros to mount, export
and umont removable disks with simple command. The removable box provide
a slot and a scsi id for each disc but contrary of Jaz/Zip/Syquest
systems, if no disc is in, no id is visible on the controller. This box
is a "Kingston like" technology.
Today, with 6.5 (6.5.3 to be precise), we have the same dynamic behavior
than O200, devices are cleaned or created at bootstart. So, I can’t
start anymore my discs with the old fashioned way. Thus, even if 6.5
brought the scsiadminswap command, O2′s scsi controller claimed "This
scsi controller does not support quiescing bus". So, it’s not even
possible to dynamically change the /dev…
Does anyone know a procedure to dynamically create coherent disk devices
so they can be mounted/unmounted WITHOUT REBOOTING system? (Of course!)
Thanx for ping back.
