Phillipe (et. al)... The Linux drivers for ATA-RAID do not support the hot-swap and hot-rebuild feature of the Promise SuperSwap line of ATA drive trays -- only the Promise provided drivers can do that (see http://www.promise.com/support/download/download2_eng.asp?productId=88&categ ory=driver&os=3 ) The problem with these drivers is that they are generally tied to the original kernel release of the RHL kernels. However, there is a way to force-load the driver with later kernel releases (see the HOWTO here: http://www.tldp.org/HOWTO/Linux-Promise-RAID1-HOWTO/modinstall.html ) Also note that the Linux kernel raid cannot be mixed with the Promise drivers... so some care is necessary (I think it is nicely covered in the above howto) I use the Promise driver over the kernel driver for precisely the reason you have inquired -- the hot rebuild capability. Good luck with your use of this information!!!

Sorry to disturb you. I have found this mail address when searching for information on experience with the promise superswap 1000 ide hot swap enclosure on linux. We have superswap 1000 enclosure here with fasttrak tx 2000 pci card, and I would like to use that with the software raid system of linux. My users request hot-swap capability, with no human intervention to initiate reconstruction. We need raid1 (mirroring). How can that be achieved ? I already tried myself, but we have several problems : - if we power up the computer with only one disk, linux will not see the second disk when it is inserted. - if we power up with two disks, and then replace one disk, the replaced disk is not initialized correctly (slow transfer e.g.) and mdadm does not see that the disk is back. We must manually issue the following script to initiate a reconstruction : mdadm -r /dev/md1 /dev/hdg2 mdadm -r /dev/md0 /dev/hdg1 sfdisk -d /dev/hde > /tmp/partitions.hdg hdparm -w /dev/hdg hdparm -d 1 /dev/hdg hdparm -m 16 /dev/hdg sfdisk /dev/hdg < /tmp/partitions.hdg mdadm -a /dev/md0 /dev/hdg1 mdadm -a /dev/md1 /dev/hdg2 - the leds are not handled the way they are with the proprietary promise driver. We currently use linux-2.4.21. Thanks in advance.
