hi, we regulary once a day got such messages in the log file. during this period (about 40 sec) the whole system hangs and it seems nothing is working on the server. we already try replace the sate cables update the firmware but nothing helps. there are 6 sata disk in the server and the strange thing that different disk fail (so it's not the problem with the disk itself, we already run test on disk too). the same system runs without problem with rhel 4, this only happened after upgrading to rhel 5. anybody has any tip? ------------------------------------------------- Jul 17 13:31:58 piros kernel: ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen Jul 17 13:31:58 piros kernel: ata4.00: tag 0 cmd 0xea Emask 0x4 stat 0x40 err 0x0 (timeout) Jul 17 13:31:59 piros kernel: ata4: soft resetting port Jul 17 13:32:01 piros kernel: ata4: softreset failed (1st FIS failed) Jul 17 13:32:01 piros kernel: ata4: softreset failed, retrying in 5 secs Jul 17 13:32:06 piros kernel: ata4: hard resetting port Jul 17 13:32:14 piros kernel: ata4: port is slow to respond, this delay is known to occur on vacant SATA ports Jul 17 13:32:37 piros kernel: ata4: port failed to respond (30 secs) Jul 17 13:32:37 piros kernel: ata4: COMRESET failed (device not ready) Jul 17 13:32:37 piros kernel: ata4: hardreset failed, retrying in 5 secs Jul 17 13:32:42 piros kernel: ata4: hard resetting port Jul 17 13:32:42 piros kernel: ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Jul 17 13:32:42 piros kernel: ata4.00: configured for UDMA/133 Jul 17 13:32:42 piros kernel: ata4: EH complete Jul 17 13:32:42 piros kernel: SCSI device sdd: 488397168 512-byte hdwr sectors (250059 MB) Jul 17 13:32:42 piros kernel: sdd: Write Protect is off Jul 17 13:32:42 piros kernel: SCSI device sdd: drive cache: write back ------------------------------------------------- -- Levente "Si vis pacem para bellum!" _______________________________________________ Redhat-devel-list mailing list Redhat-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/redhat-devel-list
