Hi, We have found that some 1TB (ST31000340AS model) and 750GB hard drives are not getting detected after reboot of NAS system. If I remove and insert it again, sometimes it get detected. Overall, its stochastic behaviour of the detection. This happens only in case of seagate drives and that too with 1TB and 750GB. Here is the log message Jan 14 05:21:07 NAS0018f8056ec9 kernel: scsi1 : sata_promise Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: SRST failed (status 0xFF) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: SRST failed (err_mask=0x100) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: softreset failed, retrying in 5 secs Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: port is slow to respond, please be patient Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2.00: ATA-8, max UDMA/133, 0 sectors: LBA48 NCQ (depth 0/32) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2.00: failed to set xfermode (err_mask=0x1) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2.00: limiting speed to UDMA/100 Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: failed to recover some devices, retrying in 5 secs Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: port is slow to respond, please be patient Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: port failed to respond (30 secs) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: COMRESET failed (device not ready) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: hardreset failed, retrying in 5 secs Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: port is slow to respond, please be patient Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: port failed to respond (30 secs) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: COMRESET failed (device not ready) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: hardreset failed, retrying in 5 secs Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: port is slow to respond, please be patient Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: port failed to respond (30 secs) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: COMRESET failed (device not ready) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: hardreset failed, retrying in 5 secs Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: port is slow to respond, please be patient Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: port failed to respond (30 secs) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: COMRESET failed (device not ready) Jan 14 05:21:07 NAS0018f8056ec9 kernel: ata2: hardreset failed, retrying in 5 secs Same issue is seen on silicon image 3114 with 4 drive controller.But surprisingly this is not observed on 3512, 2 bay controller. We are using 2.6.18 kernel and on MIPS architecture. Any pointers?
