The SSDs in question worked fine throughout, but I admit to not having fully propagated multiple backplanes with expanders full of SATA 3 SSDs.
I mentioned my experiences WRT drives that are 4k sectors with 512b emulation behaving much better with ashift=12 prior, and I also cite the standard [1][2] posts by gdamore regarding SAS expanders misbehaving when drive resets are triggered. - Rich [1] - http://gdamore.blogspot.com/2010/08/why-sas-sata-is-not-such-great-idea.html [2] - http://gdamore.blogspot.com/2010/12/update-on-sata-expanders.html On Tue, Aug 30, 2011 at 1:10 PM, Roy Sigurd Karlsbakk <r...@karlsbakk.net> wrote: >> Not only that, but I've found that the Seagate ST3500413AS (500 GB >> SATA 6Gb/s) won't work on my Intel SASUC8I HBA (basically an LSI >> SAS3081E-R, which uses the mpt driver).
