OK, here is the dmesg from last reboot, only things that are of importance to this case: SCSI subsystem initialized Fusion MPT base driver 3.04.07 Copyright (c) 1999-2008 LSI Corporation Fusion MPT SAS Host driver 3.04.07 ACPI: PCI Interrupt 0000:07:00.0[A] -> GSI 17 (level, low) -> IRQ 17 mptbase: ioc0: Initiating bringup ... mptbase: ioc1: Initiating bringup ioc1: LSISAS1068E B3: Capabilities={Initiator} PCI: Setting latency timer of device 0000:09:00.0 to 64 scsi1 : ioc1: LSISAS1068E B3, FwRev=011704dbh, Ports=1, MaxQ=829, IRQ=22 Vendor: SUN Model: LCSM100_S Rev: 0735 Type: Direct-Access ANSI SCSI revision: 05 SCSI device sdb: 204800 512-byte hdwr sectors (105 MB) sdb: Write Protect is off sdb: Mode Sense: 77 00 10 08 SCSI device sdb: drive cache: write back w/ FUA SCSI device sdb: 204800 512-byte hdwr sectors (105 MB) sdb: Write Protect is off sdb: Mode Sense: 77 00 10 08 SCSI device sdb: drive cache: write back w/ FUA sdb:end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 Dev sdb: unable to read RDB block 0 end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 unable to read partition table sd 1:0:0:0: Attached scsi disk sdb Vendor: SUN Model: LCSM100_S Rev: 0735 Type: Direct-Access ANSI SCSI revision: 05 SCSI device sdc: 241172480 512-byte hdwr sectors (123480 MB) sdc: Write Protect is off sdc: Mode Sense: 77 00 10 08 SCSI device sdc: drive cache: write back w/ FUA SCSI device sdc: 241172480 512-byte hdwr sectors (123480 MB) sdc: Write Protect is off sdc: Mode Sense: 77 00 10 08 SCSI device sdc: drive cache: write back w/ FUA sdc:end_request: I/O error, dev sdc, sector 0 Buffer I/O error on device sdc, logical block 0 end_request: I/O error, dev sdc, sector 0 Buffer I/O error on device sdc, logical block 0 end_request: I/O error, dev sdc, sector 0 end_request: I/O error, dev sdc, sector 0 end_request: I/O error, dev sdc, sector 0 end_request: I/O error, dev sdc, sector 0 end_request: I/O error, dev sdc, sector 0 Dev sdc: unable to read RDB block 0 end_request: I/O error, dev sdc, sector 0 end_request: I/O error, dev sdc, sector 0 unable to read partition table sd 1:0:0:1: Attached scsi disk sdc Vendor: SUN Model: LCSM100_S Rev: 0735 Type: Direct-Access ANSI SCSI revision: 05 SCSI device sdd: 43274240 512-byte hdwr sectors (22156 MB) sdd: Write Protect is off sdd: Mode Sense: 77 00 10 08 SCSI device sdd: drive cache: write back w/ FUA SCSI device sdd: 43274240 512-byte hdwr sectors (22156 MB) sdd: Write Protect is off sdd: Mode Sense: 77 00 10 08 SCSI device sdd: drive cache: write back w/ FUA sdd: unknown partition table sd 1:0:0:2: Attached scsi disk sdd Vendor: SUN Model: LCSM100_S Rev: 0735 Type: Direct-Access ANSI SCSI revision: 05 SCSI device sde: 204800 512-byte hdwr sectors (105 MB) sde: Write Protect is off sde: Mode Sense: 77 00 10 08 SCSI device sde: drive cache: write back w/ FUA SCSI device sde: 204800 512-byte hdwr sectors (105 MB) sde: Write Protect is off sde: Mode Sense: 77 00 10 08 SCSI device sde: drive cache: write back w/ FUA sde:end_request: I/O error, dev sde, sector 0 end_request: I/O error, dev sde, sector 0 printk: 8 messages suppressed.
