Hi I have trouble with LSI Logic / Symbios Logic MegaRAID SAS 2008 controller.
Actually I am making a backup to an LTO drive connected with LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2. $ lspci | grep 2008 03:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2008 [Falcon] (rev 03) 04:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03) During the backup the disk controler often don't responds megasasctl : megasasctl -vvv 0 adapters, driver version 00000000 It is also impossible to see the SMART states of the disks. The disks and volumes seems to function correctly and the backup continues. On controller logs (when it responds) nothing special : 12/07/15 12:06:17: MfiCmdInitQueue[0]: FW now OPERATIONAL 12/07/15 12:06:17: q.flags.mfaIs64Bits=0, q.flags.contextIs64Bits=0 12/07/15 12:06:17: q.responseQueueEntries=1f, responseQueueStatr=cd05d000 12/07/15 12:06:17: q.producerIndexPtr=cd047000, q.consumerIndexPtr=cd046000 12/07/15 12:06:17: producerIndex=0 12/07/15 12:06:18: EVT#04149-12/07/15 12:06:18: 113=Unexpected sense: Encl PD 20 Path 5d81f060d4822a00, CDB: 1c 01 07 00 20 00, Sense: 5/24/00 12/07/15 12:06:18: Raw Sense for PD 20: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 12/07/15 12:06:18: EVT#04150-12/07/15 12:06:18: 113=Unexpected sense: Encl PD 20 Path 5d81f060d4822a00, CDB: 1c 01 07 00 20 00, Sense: 5/24/00 12/07/15 12:06:18: Raw Sense for PD 20: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 12/07/15 12:06:18: EVT#04151-12/07/15 12:06:18: 113=Unexpected sense: Encl PD 20 Path 5d81f060d4822a00, CDB: 1c 01 07 00 20 00, Sense: 5/24/00 12/07/15 12:06:18: Raw Sense for PD 20: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 12/07/15 12:06:18: EVT#04152-12/07/15 12:06:18: 113=Unexpected sense: Encl PD 20 Path 5d81f060d4822a00, CDB: 1c 01 07 00 20 00, Sense: 5/24/00 12/07/15 12:06:18: Raw Sense for PD 20: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 12/07/15 12:06:18: EVT#04153-12/07/15 12:06:18: 113=Unexpected sense: Encl PD 20 Path 5d81f060d4822a00, CDB: 1c 01 07 00 20 00, Sense: 5/24/00 12/07/15 12:06:18: Raw Sense for PD 20: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 12/07/15 12:07:21: EVT#04154-12/07/15 12:07:21: 113=Unexpected sense: Encl PD 20 Path 5d81f060d4822a00, CDB: 12 01 80 00 fe 00, Sense: 5/24/00 12/07/15 12:07:21: Raw Sense for PD 20: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 12/07/15 12:07:21: EVT#04155-12/07/15 12:07:21: 113=Unexpected sense: Encl PD 20 Path 5d81f060d4822a00, CDB: 12 01 80 00 fe 00, Sense: 5/24/00 12/07/15 12:07:21: Raw Sense for PD 20: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 12/07/15 13:33:21: EVT#04156-12/07/15 13:33:21: 113=Unexpected sense: Encl PD 20 Path 5d81f060d4822a00, CDB: 12 01 80 00 ff 00, Sense: 5/24/00 12/07/15 13:33:21: Raw Sense for PD 20: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 12/07/15 13:54:54: EVT#04157-12/07/15 13:54:54: 113=Unexpected sense: Encl PD 20 Path 5d81f060d4822a00, CDB: 12 01 80 00 ff 00, Sense: 5/24/00 12/07/15 13:54:54: Raw Sense for PD 20: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 12/12/15 5:00:01: prDiskStart: starting Patrol Read on PD=00 12/12/15 5:00:01: prDiskStart: starting Patrol Read on PD=01 12/12/15 5:00:01: prDiskStart: starting Patrol Read on PD=02 12/12/15 5:00:01: prDiskStart: starting Patrol Read on PD=03 12/12/15 5:00:01: prDiskStart: starting Patrol Read on PD=04 12/12/15 5:00:01: EVT#04158-12/12/15 5:00:01: 39=Patrol Read started 12/12/15 8:09:00: prCallback: PR completed for pd=04 12/12/15 8:11:33: prCallback: PR completed for pd=03 12/12/15 8:15:22: prCallback: PR completed for pd=00 12/14/15 0:06:14: prCallback: PR completed for pd=01 12/14/15 0:11:39: prCallback: PR completed for pd=02 12/14/15 0:11:39: PR cycle complete 12/14/15 0:11:39: EVT#04159-12/14/15 0:11:39: 35=Patrol Read complete 12/14/15 0:11:39: Next PR scheduled to start at 12/19/15 5:00:01 On /var/log/kern.log I get : Dec 16 10:53:51 theta1 kernel: [769640.032639] sdc: detected capacity change from 500103667712 to 0 Dec 16 11:18:17 theta1 kernel: [771106.162471] scsi 1:0:2:0: Sequential-Access HP Ultrium 5-SCSI Z5AD PQ: 0 ANSI: 6 Dec 16 11:18:17 theta1 kernel: [771106.162483] scsi 1:0:2:0: SSP: handle(0x0009), sas_addr(0x500110a0014c8dd0), phy(3), device_name(0xa0100150d28d4c01) Dec 16 11:18:17 theta1 kernel: [771106.162488] scsi 1:0:2:0: SSP: enclosure_logical_id(0x5141877047b73100), slot(4) Dec 16 11:18:17 theta1 kernel: [771106.162494] scsi 1:0:2:0: qdepth(254), tagged(1), simple(0), ordered(0), scsi_level(7), cmd_que(1) Dec 16 11:18:17 theta1 kernel: [771106.164855] scsi 1:0:2:0: TLR Enabled Dec 16 11:18:17 theta1 kernel: [771106.167348] st 1:0:2:0: Attached scsi tape st0 Dec 16 11:18:17 theta1 kernel: [771106.167354] st 1:0:2:0: st0: try direct i/o: yes (alignment 4 B) Dec 16 11:18:17 theta1 kernel: [771106.167585] st 1:0:2:0: Attached scsi generic sg5 type 1 Dec 16 11:29:28 theta1 kernel: [771777.767773] st0: Block limits 1 - 16777215 bytes.

The ST91000640NS are the drives in RAIDs (+ a spare). This lines have appaired when I have done a "echo "- - -" >/sys/class/scsi_host/host0/scan". Failure in mpt2sas has appeared after the problem begins mpt2sas is the driver of the SAS controller for the LTO drive, not the disks.
