I am having a strange issue with a HP Ultrium 3000 LTO drive connected to a LSI MegaRAID SAS 9280-24i4e controller. It appears to write ok to tape, but on rewind it fails. If I eject the tape and reinsert it reads ok. It appears that the rewind times out with the following kernel warnings Jun 7 15:44:22 aleph kernel: mfi0: 4304 (423900863s/0x0002/info) - Inserted: PD 29(e0xff/s0) Jun 7 15:44:22 aleph kernel: mfi0: 4305 (423900863s/0x0002/info) - Inserted: PD 29(e0xff/s0) Info: enclPd=ffff, scsiType=1, portMap=00, sasAddr=500110a001535d9c,0000000000000000 Jun 7 15:46:38 aleph kernel: mfi0: 4306 (423900999s/0x0002/WARN) - PD 29(e0xff/s0) Path 500110a001535d9c reset (Type 03) Jun 7 15:46:51 aleph kernel: mfi0: 4307 (423901012s/0x0002/WARN) - PD 29(e0xff/s0) Path 500110a001535d9c reset (Type 03) Jun 7 15:47:04 aleph kernel: mfi0: 4308 (423901025s/0x0002/WARN) - PD 29(e0xff/s0) Path 500110a001535d9c reset (Type 03) Jun 7 15:47:17 aleph kernel: mfi0: 4309 (423901038s/0x0002/WARN) - PD 29(e0xff/s0) Path 500110a001535d9c reset (Type 03) Jun 7 15:47:30 aleph kernel: mfi0: 4310 (423901051s/0x0002/WARN) - PD 29(e0xff/s0) Path 500110a001535d9c reset (Type 03) Jun 7 15:47:43 aleph kernel: mfi0: COMMAND 0xffffff80005a32a8 TIMEOUT AFTER 39 SECONDS Jun 7 15:47:43 aleph kernel: mfi0: 4311 (423901064s/0x0002/WARN) - PD 29(e0xff/s0) Path 500110a001535d9c reset (Type 03) Jun 7 15:47:56 aleph kernel: mfi0: 4312 (423901077s/0x0002/WARN) - PD 29(e0xff/s0) Path 500110a001535d9c reset (Type 03) Jun 7 15:48:09 aleph kernel: mfi0: 4313 (423901090s/0x0002/WARN) - PD 29(e0xff/s0) Path 500110a001535d9c reset (Type 03) Jun 7 15:48:22 aleph kernel: mfi0: 4314 (423901103s/0x0002/WARN) - PD 29(e0xff/s0) Path 500110a001535d9c reset (Type 03) Jun 7 15:48:35 aleph kernel: mfi0: 4315 (423901116s/0x0002/WARN) - PD 29(e0xff/s0) Path 500110a001535d9c reset (Type 03) Eventually after a couple of minutes of the tape running back and forth I get an I/O error.
