Wrong driver for SAS controller?

Hi,

I have an AVAGO MegaRaid 3316 SAS controller on FreeBSD 12.2 and get problems with it every some weeks like this:

Code:
(sa0:mrsas0:1:25:0): LOAD UNLOAD. CDB: 1b 00 00 00 00 00                       
(sa0:mrsas0:1:25:0): CAM status: SCSI Status Error                             
(sa0:mrsas0:1:25:0): SCSI status: OK                                           
(sa0:mrsas0:1:25:0): REWIND. CDB: 01 00 00 00 00 00                             
(sa0:mrsas0:1:25:0): CAM status: SCSI Status Error                             
(sa0:mrsas0:1:25:0): SCSI status: OK

and no more actions are possible regarding the tape library connected to it.

When looking for possible problems, I saw that the supported driver for the SAS 3316 is the mpr driver, but here the mrsas driver is used?

So, I wonder if I can switch to the mpr driver?

Thanks for any info on this.

mpr(4) is a different LSI/Avago/Broadcom chipset. You can only switch between mfi(4) and mrsas(4).

I'd take a look at pciconf -lv because it's probably a different model card than you think it is.

This is what pciconf -lv says:

Code:
mrsas0@pci0:65:0:0:     class=0x010700 card=0x9a901000 chip=0x00ce1000 rev=0x01 hdr=0x00
    vendor     = 'Broadcom / LSI'
    device     = 'MegaRAID SAS-3 3316 [Intruder]'
    class      = mass storage
    subclass   = SAS

Just some update: I aborted a test with Ubuntu, as I wasn't able to get the LTO-8 drive to stream (> 120 MB/sec).

Anyway, as a reboot of the server never helped, it's probably NOT a driver issue.

More likely it's a problem with too high temperature of the SAS Controller. Now testing with more fans in full speed mode. I will report in some months, if the problem reoccurs.

Yeah, these types of cards can get really hot. Most of them are passively cooled too, so you need to make sure there's enough airflow over them.
