rescanning FC LUNs ( RH ES Linux 2.1, qlogic)
Hi
I hope therea are any FC-linux experts her
I run some boxes with qlogic fibrechannel hostbus adapters (HBAs ), and they seem to work well, except I can't find a way to find new
devices without rebooting.
I've tried the trick about poking into proc, but to no avail :
echo "scsi add-single-device 0 1 2 3" >/proc/scsi/scsi
with the numbers replaced accordingly. ( host, channel Id, lun)
This did work in roughly the same environment on an cpqfc HBA , but qla2300 refuses to see anything new until after a reboot ( rmmod and modprobe might have done the trick also, but at the moment I don´t have the opurtunity to run it as a module.
I´ll gladly provide more info, if that can help.
Best Regards,
Morten
