We have bad experience with > 510 in the past I tried with Intel X25-M 160 and 80 GB and a X25-E 64 GB (only because that was what I had in my drawer). I am not sure which one of them that made it lock up, maybe it was all of them. Since the head is a X4150 with 8 slots and a plain LSI SAS HBA, I put them in there instead and went ahead. > Yes, "logical-block" make it faster in MPxIO setup. > > If you are using 9205-8E, you don't need to use "stmsboot -e" > By default, mpt_sas driver for 9205-8E is already MPxIO enable. > "stmsboot-e" is useful to enable old 3G HBA MPxIO feature. Ok, thanks for the information, good! So it just changes the mpxio-disable="yes"/"no" in the <driver>.conf files? > With MPxIO like the following setup, you can protect HBA, cable, JBOD SAS IO > module failure > > http://dataonstorage.com/dataon-solutions/125-unified-storage-system.html That is almost what I do, except that I only have one HBA. We haven't seen many HBAs fail during the years, none actually, so we thought it was overkill to double those too. But maybe we are wrong? > the slot 0 issue is related to their SES mapping in JBOD FW.

I will try to update the firmware in the chassis and see what that gives. I really hesitate to use HP HBAs - if they have changed anything from the OEM firmware it is hard to tell how compatible they are. /ragge _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
