Hi,

I am using Kernel 2.6.7 and I want to use the Large Block Device for the 
3.5TB Infortrend FC-Sata RAID.

My H/W is QLA2300, Infortrend A16F-G1A2 FC-SATA RAID, and a Intel Xeon SMP 
box.

I also turned on the "LBD support" in the kernel config.

But the kernel recognize only 1.5TB out of 3.5TB, even though it is one 
volume with 3.5TB.

qla2300 0000:03:09.0: Found an ISP2300, irq 27, iobase 0xf8c5c000

Do I need to do something about qla2300 driver or else, in order to make the 
kernel recognize 3.5TB?

Please help me. Any help will be appreciated.

Thanks in advance.

LVM is not an option for  me, because I will not do volume management for 
this 3.5TB.

Thanks.

I have confirmed on 2.4.20 that the maximum size for a lun is 2 TB.  
Maybe a limitation of the driver's addressing scheme ? Has anyone
tried this with 2.6.x ?  It seems that for 2.4, LVM or MD driver
are your only options.

The drive itself replied with that capacity, which is incorrect.  It's
supposed to reply with the largest possible capacity (0xffffffff) and we
use that as a signal to retry with READ_CAPACITY_16.

Could you contact the support line of the array and make sure of two
things:

1) It does actually support single LUNs with a capacity of >2TB (lots of
arrays don't)
2) And if 1) is true, why is it not responding correctly to the READ
CAPACITY(10)? The spec (spc-2 Rev 8, 5.2.11) says "If the number of
logical blocks exceeds the maximum value[...]the device server shall
transfer FFFFFFFFh in the RETURNED LOGICAL BLOCK ADDRESS field"

Is this true of both 2.4 and 2.6 ?

No, only 2.6 has the correct LBD support.

I have sent the those 2 questions to the Infortrend. When I get the answer, 
I will get back to you.

Thank you very much.

Looking at an FC trace on an Infortrend controller I have, shows that
for a LUN 3586680 MB in size, the LBA is B5D3BFFF in the "RETURNED
LOGICAL BLOCK ADDRESS FIELD" 
and with in the "BLOCK LENGTH IN BYTES FIELD" field is 200h , ( B5D3BFFF
* 200h =  approx. 1.6 TB). Seems that infortrend does NOT respond
properly to READ_CAPACITY_10, at least in my case. 
James, this may be a dumb question, please excuse my ignorance of the
internals of the scsi subsystem, 
but is there a plan to implement LBD support in the 2.4 tree ?

Well 3586680 MB == 0x1b5d3bfff * 0x200

so I think you can see where the returned figure is coming from...

Infortrends should be made aware of the problem so they can do a bios
upgrade.  I suspect that even if the array returned the correct capacity
it would be unable to process the READ/WRITE(16) commands necessary to
reach it anyway, so their "fix" may be to tell you that no individual
luns can be configured beyond 2TB.

The problem is not just in SCSI, it permeates the block layer.  I don't
think there's much point backporting LBD to 2.4, although many vendor
trees have it.

James,You guessed right, I sent a read capacity 16 cdb to the controller
and recieved a 
check condition back: sense 05 illegal request and additional qualifiers
2000 = invalid 
command operation. Seems as though controller was not architected to
support luns greater
than 2 .1 TB. The size of any lun > than 2 .1 TB will be set as a modulo
2.1 TB
