Hi folks, I'm running a new server with FreeBSD 7.0-RELEASE and am seeing timeouts and other messages with mpt0 These include: mpt_cam_event: 0x16, 0x12 & 0x60 More importantly these: Dec 28 16:33:30 ted kernel: mpt0: request 0xc68db554:44729 timed out for ccb 0xc691f000 (req->ccb 0xc691f000) Dec 28 16:33:30 ted kernel: mpt0: request 0xc68d8bc4:44730 timed out for ccb 0xc6ac1c00 (req->ccb 0xc6ac1c00) Dec 28 16:33:30 ted kernel: mpt0: attempting to abort req 0xc68db554:44729 function 0 Dec 28 16:33:30 ted kernel: mpt0: request 0xc68d8328:44731 timed out for ccb 0xc68df800 (req->ccb 0xc68df800) Dec 28 16:33:30 ted kernel: mpt0: mpt_recover_commands: IOC Status 0x4a. Resetting controller. Dec 28 16:33:30 ted kernel: mpt0: completing timedout/aborted req 0xc68db554:44729 Dec 28 16:33:30 ted kernel: mpt0: completing timedout/aborted req 0xc68d8bc4:44730 Dec 28 16:33:30 ted kernel: mpt0: completing timedout/aborted req 0xc68d8328:44731 Dec 28 16:33:30 ted kernel: mpt0: request 0xc68d5ac8:0 timed out for ccb 0xc6af4000 (req->ccb 0) I have raised this with my provider and they have said "it is working fine without any problem you can simply ignore this message". Now I'm no expert on the megaraid controller but I'm fairly certain that frequent timeouts are not something that I want to be seeing. I looked around and saw other people asking the same but no answers posted publicly. I was also wondering as to whether linux emulation could be used to run the LSI Megaraid storage manager or whether attempting to do so is a very bad idea.. Thanks, Colin Southport Computers.
