Hello I'm having some problems with a the LSI SAS controller in a Sun x4200 machine. I can't get the hotplugging of disks to work. When I boot the machine with all the disks in place on kernel 2.6.16.16 it find them all right. But when I remove a drive and reinsert it, this happens: May 23 16:40:02 localhost kernel: mptsas: remove event for non-existant PHY. May 23 16:42:22 localhost kernel: mptsas: add event for non-existant PHY. When the drive is removed, the device disappears, but when it's reinserted I just the "add event for non-existant PHY." message and no device appears. I tried it with kernel 2.6.17-rc4 too, booting the machine and then inserting the drive. Nothing happens, noting at all. Drives attached when the machine is booted works great on both kernels. I've been fooling around with scsiadd too, with no results. But my understanding is that this shouldn't be needed with SAS? Are there any known issues with this controller? I haven't been able to find anything online. This is what /proc/scsi/mptsas/0 says about the controller: ioc0: LSISAS1064, FwRev=01040000h, Ports=1, MaxQ=511 Distro is Debian Stable, with our own kernel.
