Hi,
when trying to do a rescan on (1) sata_nv/2.6.18 (2) sym53c83xx/2.6.21,
I get:
11:40 sun:~ # cd /sys/class/scsi_host/host0/
11:40 sun:../scsi_host/host0 # ls
can_queue device proc_name sg_tablesize subsystem
unchecked_isa_dma
cmd_per_lun host_busy scan state uevent unique_id
11:40 sun:../scsi_host/host0 # echo 1 >scan
-bash: echo: write error: Invalid argument
What is the proper way to trigger a rescan, if it comes to be necessary?
thanks,
Jan

This doesn't appear to work either (2.6.22, sata_nv).
