Greetings.

I've got three (3) Seagate U160 10,000rpm ST173404LCV drives (80-pin
LVD's w/ 68-80 converters) that hook up well and run off the embedded
Adaptec 7899W controller just fine.

However, I've just decided to go RAID and picked up a LSI MegaRAID Elite
1600 to use for the intended RAID 5 setup. Obviously the jumpering and
drive IDs were okay as proved on the Adaptec, but I cannot get the LSI
controller to recognize the physical drives at all. I've tried many
things...of course, narrowing it down to just one drive even. I've
poured through the extensive LSI manual and Seagate configuration guide
and trying several combinations of jumpering and BIOS settings along the
way.

Does anyone here have any suggestions that I may have overlooked?

Thanks!!

Resolved. Here's the scoop:

Perhaps the 80-68 pin converters are not as good as they say on them
(Claim to be U320 compliant). Anyway, backed the MegaRAID Elite 1600
from the default U160 to UltraII and drives were recognized.

Therefore, the converters, terminator, and/or cable are not what they
claim to be and are hurting performance and not letting the drives be
recognized at U160 speeds.

Your logic is astounding.

Care to explain how the ASC-39160 compatible controller had no pro-
blems with the same configuration?

After talking with LSI they think the Adaptec is able to get a glimpse

of the drives faster and automatically fallback to a slower speed
whereas thier controller was unable to. Pure speculation at this point.

I don't think there is any difference in negotiation startup for drives of lower
than Ultra160 and for Ultra160 and up, so any negotiation for speed would be
async and narrow. No need to fallback since there is nothing to fall back from.

Doesn't mean it can't at least show what device it is.
Ultra160 has Domain Validation (SureLink in LSI speak). It is either
automatic or it can be enabled/disabled. If the latter then enable it.

So either way there is no reason for the LSI to not see devices.

No, the Adaptec shows you what busspeed was negotiated so you don't need to
speculate at all.

There was simply no way it would work without slowing the bus speed down.

LSI Tech Support suggested the 80-to-68 pin converters didn't keep the

electrical path clean enough to run at U160

I don't know for sure. The "Sync" speed the Adaptec BIOS showed was 80,

but is that just plain 80 (UltraII) or 80 dual-clock (U160)?
I don't know for certain if the Adaptec will say 160 or not instead as I
have not U160 68-pin drives to try now. I do, however, have some
different 68-pin cables and terminators on the way [to disperse drive
across the empty channels] and will try them and see if that resolves
the slowdown.

Did you check Sure Link?

What does it say in CTRL-A Setup for that? Wouldn't it just follow that
what it says in CTRL-A Setup , SCSI device configuration, "Sync Transfer
Rate (MB/Sec)" is also what is displayed during POST device scan?

I have no idea what Sure Links or Domain Validation is.

The clustering option is turned off as I don't need it.

I imagine its automatic? I've seen no mention of this in the manuals.

That would likley be an 80 sync speed on the Adaptec as well.

I ran into the same problem last week when I upgraded to an LSI Elit
1600 and 4 "ebay special" ST173404LCV drives. It seems that th
drives have an OEM bios on them and won't respond to anything highe
then 80mb. However, I have found a ST173404LC bios that will allo
160MB transfer rate. I've been using this for a week and afte
loading over 150GB haven't ran into any problems. The drives repor
as an LC instead of LCV but the full cache of 16MB is shown. Emai
me if you need the fix
