next in thread | raw e-mail | index | archive | help
I have some systems which I plan to upgrade from 8.4 to 10.3 once 10.3
is released. In the meantime, I'm testing 10.3-BETA2 and have found what
appears to be a regression in the MPT driver.
The system is a Dell PowerEdge R300 with a Dell SAS6 controller:
mpt0@pci0:5:0:0: class=0x010000 card=0x1f0e1028 chip=0x00581000 rev=0x08 hdr=0x00
vendor = 'LSI Logic / Symbios Logic'
device = 'SAS1068E PCI-Express Fusion-MPT SAS'
class = mass storage
subclass = SCSI
Both the system BIOS and the SAS6 firmware are at the latest revisions
from Dell (which haven't changed in years).
On the 8.4 system, "grep mpt /var/run/dmesg.boot" reports:
mpt0: <LSILogic SAS/SATA Adapter> port 0xec00-0xecff mem 0xdfcec000-0xdfceffff,0xdfcf0000-0xdfcfffff irq 16 at device 0.0 on pci5

[I'm not sure what that ILLEGAL REQUEST is about.]
On the same system, running 10.3-BETA2 r295785, I see:

I can try to narrow down when this regression was introduced, but I fig-
ured I'd report it in case somebody has an "ah-hah" moment from seeing it.
Also, there has always been an issue with passthru on these controllers -
as you can see above, there are 2 physical disks attached to the controller,
used as a mirror volume. But only one of the members appears as a passN de-
vice, which means that the other one can't be monitored with smartmontools.
If I'm remembering correctly, a volume with more than 2 drives creates a
passN device for all but one of the drives.
