vendor "Symbios Logic", unknown product 0x007e (class mass storage
subclass SAS, rev 0x03) at pci19 dev 0 function 0 not configured
Such devices can be found on SPARC T4 machines, they are eMLC flash
accelerator cards.
After looking into mpii(4) and jmatthew guessing that attaching them
might just work, here's a diff to do so:

It exports four disks of which all look identical except for existing
labels/filesystems:
# disklabel sd2
# /dev/rsd2c:
type: SCSI
disk: SCSI disk
label: ATA-2E256-TU2-51
duid: 0000000000000000
flags: vendor
bytes/sector: 512
sectors/track: 56
tracks/cylinder: 224
sectors/cylinder: 12544
cylinders: 31138
total sectors: 390625001
boundstart: 0
boundend: 390625001
drivedata: 0
16 partitions:
# size offset fstype [fsize bsize cpg]
a: 263424 0 4.2BSD 2048 16384 16

c: 390625001 0 unused
g: 390068224 526848 4.2BSD 2048 16384 16
I can successfully create labels on the disk and write with decent speed:
# dd if=/dev/zero of=/mnt/10G bs=1m count=$((10*1024)) conv=fsync
10240+0 records in
10240+0 records out
10737418240 bytes transferred in 23.696 secs (453123305 bytes/sec)
Is that product name appropiate or rather too long? Other models such
as the F40 feature 400G for example.
OK?
