Re: RE pm8001 bug - pcieport error when loading 'pm8001' driver / no backplane drives seen

Thank you for a quick reply - but I'm not sure I understand correctly...

The 'esas2hba' driver wasn't even installed - I downloaded and compiled
it later, after I couldn't get pm8001 to 'see' drives on the backplane.

If I use a MiniSAS to 4x SATA cable, the pm8001 driver works perfectly
with the ATTO - even with the 'pcieport' error. It's only when the
drives are in the enclosure / backplane. that the pm8001 driver doesn't
'see' them.

You are right - all of my drives are SATA, connected to a SAS backplane,
which is connected to the HBA via a SAS expander / midplane (at least as
far as I understand).

I don't quite understand what you mean by 'affiliations with esas2hba'
(especially since there was no 'esas2hba' driver in the beginning)?

I'm quite new to SAS and especially to 'expanders', so maybe I'm missing
something obvious...
