[-- Attachment #1 --] Hello list, Basically I'm experiencing the same problem as described here : https://forums.freebsd.org/showthread.php?t=9407 (linking for reference) Drives disconnections are not recognized instantly, and instead I get the following dmesg entries : mpt0: mpt_cam_event: 0x16 mpt0: mpt_cam_event: 0x16 (Sometimes I also get "mpt0: mpt_cam_event: 0x12" events) This is really crippling as this litterally paralyzes the ZFS pool until the controller finally comes to its senses (...or until a disk gets replugged in, which provokes a flush of all the buffered failed SCSI requests). Hardware is recognized as : mpt0@pci0:6:8:0: class=0x010000 card=0x1f041028 chip=0x00541000 rev=0x01 hdr=0x00 vendor = 'LSI Logic (Was: Symbios Logic, NCR)' device = 'SAS 3000 series, 8-port with 1068 -StorPort' class = mass storage subclass = SCSI Did anyone else experience this, or find a proper work-around ?
