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 :)

same mobo (Intel S5520HC) here, and also BIOS configured such that the AHCI driver is being used. I noted the same as you: hotswap does not seem to work - detecting a new disk appears to need a cold start. (I did not try to play with something like echo "0 0 0"
/sys/class/scsi_host/host<n>/scan )
Hotswap does work on all my non-S5520HC mobos that have AHCI, though.
HTH, Kay
