Hi guys, We've just been delivered a system that I'm testing, consisting of: - SuperMicro CSE-847E16-R1400LPB (4U, PSU 2x1400W (1+1), SAS2 expander) - SuperMicro X8DTL-iF LGA1366 Single - Intel Xeon E5620 2,4GHz, 12MB cache TRAY - 3x Hynix RAM 4 GB DDR3 1333 Reg. ECC - LSI SAS3081E-R, 8-port int. SAS - kit (CIe x8, 8-port SAS/SATA, 0, 1, 1E, JBOD) - 3ware ML SFF-8087 til ML SFF-8087 0,6m (SAS cable, connect SFF-8087 Controller) - 36x Samsung 2TB SATAII/5400 HD203WI (8.9ms, 32MB Cache, EcoGreen F2) The system will be a backup server running ZFS on FreeBSD 8.1, and I'm more concerned with stability and volume size pr dollar than I am about performance, hence the 2TB SATA drives. Now, I've installed FreeBSD and set the disks up to 6x raidz1 with six disks in each raidz1. Not necessarily the best configuration, but that's not the issue for this discussion. The problem is that when I pull a disk out (thus simulating it failing), the entire disk array stops, and I cannot even do a 'reboot now', I have to cold boot the machine to get it back online again. This is me removing the disk that should be da0 while it's running: mpt0: mpt_cam_event: 0x16 mpt0: mpt_cam_event: 0x12 mpt0: mpt_cam_event: 0x16 mpt0: mpt_cam_event: 0x16 mpt0: mpt_cam_event: 0x12

way when I pull out a disk that is meant to be hot-swappable? Is it something in the driver? Something in the hardware? Somthing known? Something that I've misunderstood about being able to replace disks? Cheers Nik
