Hi all,
I changed a bad disk (automaticly disabled from software raid1 and system for I/O error) in one of our servers and now have problem with adding new one to system without reboot. Does anybody have an experience with this? Or is it possible? :) We're using hotswap AXX6DRV3G for 6 SATA disks from Intel connected directly to MB (S5520HC from Intel too). There is AHCI as driver (enabled in bios), no HW raid. I found, something like that
echo "0 0 0" >/sys/class/scsi_host/host<n>/scan
but it found only sda disk which is already running.. Using CentOS 5.5, x86_64.
Thanks for your ideas and replies ... and excuse my english please :)

I use the following command to rescan all scsi devices
for f in /sys/class/scsi_host/host*; do echo "- - -" > $f/scan; done
You can also rescan the partitions on the devices with
partprobe -s /dev/sd?
