Hi, Whilst kernel.org is in recovery, does anyone have a copy of this page? http://ata.wiki.kernel.org/index.php/Libata_error_messages Background: linux-3.0. We have a SiI3124 SATA controller connected to 4 SiI3826 PMPs, with 5 disks each on each of the 1st 3 PMPs. We've been performing a moderate write load to the 1st and 3rd PMPs (loading up data over the network). The 2nd PMP has been unused (disks not mounted). However we had a number of errors reported on the last disk of the unused 2nd PMP: $ grep -A1 'exception Emask' /var/log/kern.log Oct 23 17:03:54 b2 kernel: [174268.531357] ata2.04: exception Emask 0x10 SAct 0x0 SErr 0x4010000 action 0xf Oct 23 17:03:54 b2 kernel: [174268.533946] ata2.04: SError: { PHYRdyChg DevExch } -- Oct 23 17:19:17 b2 kernel: [175192.489591] ata2.04: exception Emask 0x10 SAct 0x0 SErr 0x4010000 action 0xf Oct 23 17:19:17 b2 kernel: [175192.492189] ata2.04: SError: { PHYRdyChg DevExch } -- Oct 23 17:39:35 b2 kernel: [176410.375953] ata2.04: exception Emask 0x10 SAct 0x0 SErr 0x4010000 action 0xf Oct 23 17:39:35 b2 kernel: [176410.378545] ata2.04: SError: { PHYRdyChg DevExch } -- Oct 23 17:54:40 b2 kernel: [177315.299991] ata2.04: exception Emask 0x10 SAct 0x0 SErr 0x4010000 action 0xf Oct 23 17:54:40 b2 kernel: [177315.302595] ata2.04: SError: { PHYRdyChg DevExch } After the last one that port dropped out altogether: Oct 23 17:54:58 b2 kernel: [177332.952204] ata2.04: PHY status changed but maxed out on retries, giving up Oct 23 17:54:58 b2 kernel: [177332.954696] ata2.04: Manully issue scan to resume this link Cheers, Chris -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
