So i was tracking down why i can't do a 'camcontrol inq'
on aac.
When i do:
camcontrol inq 0:2 -v
I get:
pass1: <IBM IC35L146UCDY10-0 S27E> Fixed unknown SCSI-3 device
CAM status is 0x12
[long pause, ~30s?]
camcontrol: error getting transfer settings
CAM status is 0x6
camcontrol cmd pass1 -v -c "12 01 00 00 01 00" -i 1 "b3 b5"
0 31
----------
According to the docs, the second of these numbers should be 0, unless
the LUN (pass1) is not present, in which case 31 is correct, but then
the first number should be 3. Maybe this is what the RAID is botching,
and what "camcontrol inquiry" can't handle to get the serial number.
Byte | Bit

0 | Peripheral Device Type | Peripheral Qualifier
"Peripheral Qualifier is set to zero to indicate that the LUN
specified in the IDENTIFY Message is currently supported. Peripheral
Qualifier is set to 011b when the LUN specified in the IDENTIFY
Message is not present.
Peripheral Device Type is set to zero to indicate that the device is
a Direct-Access. Peripheral Device Type is set to 1Fh when the LUN
specified in the IDENTIFY Message is not present."
