Running OI151a on a Supermicro X8DTH-6F board, which has an LSI 2008 8-Port 6Gbps SAS controller, with 8 SAS internal drives, plus an SSD for the boot disk. I am running the mpt_sas driver. The server became unresponsive to any commands (couldn't even do a remote reboot). I did a hard reset on server, which seems to have resolved the issues (scrub showed no errors and iostat is OK).
My question, any ideas why this happened and if there is something I can do to avoid this issue in the future. some errors in the /var/adm/messages: Jan 9 09:58:50 ml-oi1 scsi: [ID 107833 kern.warning] WARNING: /pci@0,0/pci8086,3410@9/pci15d9,400@0 (mpt_sas0): Jan 9 09:58:50 ml-oi1 Disconnected command timeout for Target 16 iostat -En showed lots of different errors (mostly "No Device"). c4t0d0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: ATA Product: INTEL SSDSA2CT04 Revision: 0362 Serial No: CVPR136307X1040 Size: 40.02GB <40020664320 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 10 Predictive Failure Analysis: 0 c4t2d0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: ASUS Product: DRW-24B1ST a Revision: 1.04 Serial No: Size: 0.00GB <0 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 2 Predictive Failure Analysis: 0 c2t5000C50033F5BF9Fd0 Soft Errors: 0 Hard Errors: 5 Transport Errors: 0 Vendor: SEAGATE Product: ST1000NM0001 Revision: 0001 Serial No: Z1N00DS70000S12 Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 5 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c2t5000C50033F5BD7Fd0 Soft Errors: 0 Hard Errors: 4 Transport Errors: 0 Vendor: SEAGATE Product: ST1000NM0001 Revision: 0001 Serial No: Z1N00DSE0000S11 Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 4 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c2t5000C50033F5BFFBd0 Soft Errors: 0 Hard Errors: 4 Transport Errors: 0 Vendor: SEAGATE Product: ST1000NM0001 Revision: 0001 Serial No: Z1N00J5Z0000S12 Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 4 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c2t5000C50033F5BE3Bd0 Soft Errors: 0 Hard Errors: 6 Transport Errors: 0 Vendor: SEAGATE Product: ST1000NM0001 Revision: 0001 Serial No: Z1N00DRT0000S12 Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 6 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c2t5000C50033F5C5E7d0 Soft Errors: 0 Hard Errors: 5 Transport Errors: 0 Vendor: SEAGATE Product: ST1000NM0001 Revision: 0001 Serial No: Z1N00J680000S12 Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 5 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c2t5000C50033F5D607d0 Soft Errors: 0 Hard Errors: 10 Transport Errors: 0 Vendor: SEAGATE Product: ST1000NM0001 Revision: 0001 Serial No: Z1N00E2W0000S12 Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 10 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c2t5000C50033F5C16Fd0 Soft Errors: 0 Hard Errors: 2 Transport Errors: 0 Vendor: SEAGATE Product: ST1000NM0001 Revision: 0001 Serial No: Z1N00DTC0000S12 Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 2 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c2t5000C50033F5BFBBd0 Soft Errors: 0 Hard Errors: 597 Transport Errors: 0 Vendor: SEAGATE Product: ST1000NM0001 Revision: 0001 Serial No: Z1N00J310000S12 Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 597 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 Here is an example from an fmdump -eV: Jan 09 2012 10:04:31.334477741 ereport.io.scsi.cmd.disk.dev.rqs.derr nvlist version: 0 class = ereport.io.scsi.cmd.disk.dev.rqs.derr ena = 0xc3ca9ccb73e00c01 detector = (embedded nvlist) nvlist version: 0 version = 0x0 scheme = dev device-path = /pci@0,0/pci8086,3410@9/pci15d9,400@0/iport@80/disk@w5000c50033f5bfb9,0 devid = id1,sd@n5000c50033f5bfbb (end detector) devid = id1,sd@n5000c50033f5bfbb driver-assessment = retry op-code = 0x28 cdb = 0x28 0x0 0x11 0x5d 0x75 0xf9 0x0 0x1 0x0 0x0 pkt-reason = 0x0 pkt-state = 0x37 pkt-stats = 0x0 stat-code = 0x2 key = 0x6 asc = 0x29 ascq = 0x2 sense-data = 0x70 0x0 0x6 0x0 0x0 0x0 0x0 0xa 0x0 0x0 0x0 0x0 0x29 0x2 0x2 0x0 0x0 0x0 0xdd 0xba __ttl = 0x1 __tod = 0x4f0b2c2f 0x13efb9ad thanks, Geoff _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
