I have a machine with FreeBSD (4.3-R) and Mylex RAID controller: mly0: mem 0xfc000000-0xfc001fff irq 5 at device 4.1 on pci2 mly0: AcceleRAID 352 , 2 channels, firmware 6.00-1-00 (20000426), 32MB RAM It is configured as RAID 5 with 4 HDDs (hotswappable) Recently one of the HDDs' indicator turned red. The drive was taken out, and then put back. Some time later the red light went away. Here is what I see in the logs: Mar 31 23:22:52 host /kernel: mly0: physical device 1:3 command timeout Mar 31 23:22:52 host /kernel: mly0: logical device 0 (da0) critical Apr 1 16:38:40 host /kernel: mly0: physical device 1:3 device cannot be accessed Apr 1 16:40:00 host /kernel: mly0: physical device 1:3 found Apr 1 16:40:00 host /kernel: mly0: physical device 1:3 automatic rebuild started Apr 1 17:22:58 host /kernel: mly0: logical device 0 (da0) automatic rebuild started Apr 1 17:22:58 host /kernel: mly0: logical device 0 (da0) rebuild completed Apr 1 17:22:58 host /kernel: mly0: physical device 1:3 rebuild completed Apr 1 17:22:58 host /kernel: mly0: physical device 1:3 online Apr 1 17:22:58 host /kernel: mly0: logical device 0 (da0) online My questions: 0. What has probably happened here ? 1. Does this mean that the HDD is alright, or it needs to be replaced ? 2. Is there any way to test this (HDD and RAID integrity) from within FreeBSD ? Is there an utility or something else for that ? 3. If I need/decide to replace the HDD - can I do that while the computer is running ? Would the controller take proper care of the new HDD upon inserting the new HDD, or I need to do manual configuration/formating ? Thanks. Igor PS. Please keep my address in Cc:
