[Bug 578212] [NEW] Supermicro AOC-SASLP-MV8 card errors when creating software RAID array

[Alex Harrington]

Public bug reported:

I have one of these cards - Marvell 88SE6480 chip I believe, BIOS
version is 3.1.0.15N.

I'm booting off a Lucid desktop usb boot drive. Also tried with rescue
mode on a Lucid 64 bit server usb key.

Machine boots off USB fine and I can partition 4 1TB SATA Hitachi drives
attached to the controller with a breakout cable.

After installing mdadm, (apt-get install mdadm) I create a new md device as follows:
mdadm --create /dev/md0 --raid-devices=2 --spare-devices=2 --level=1 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1

That normally completes fine but looking at /proc/mdstat the resync
quickly slows to a halt and then I get the following logged repeatedly
in dmesg:

[  591.992563] /build/buildd/linux-2.6.32/drivers/scsi/mvsas/mv_sas.c
1608:mvs_query_task:rc= 5

Eventually I start getting errors logged that imply the drives are
faulty. Which drive it chooses to say is faulty varies from boot to
boot. The drives came from a working machine and have about 6 months on
them. I'm confident there's no problem with them.

After it picks a drive to fail, I get the following in dmesg:

[  560.988051] sd 3:0:0:0: [sdb] Unhandled error code
[  560.988055] sd 3:0:0:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_TIMEOUT
[  560.988060] sd 3:0:0:0: [sdb] CDB: Read(10): 28 00 00 00 6a 3f 00 00 08 00
[  560.988076] end_request: I/O error, dev sdb, sector 27199

I've found several threads on the kernel mailing list about this - but
no resolution.

The server is currently waiting to go in to production, so I've got a
window where I can run any tests required to resolve.
