It was my understanding from a recent discussion with Sun that you can't multipath to SATA drives. Multipathing is specific to SAS and there's no support in SATA for this.

The J4400 has two SIM's, and we've connected each SIM's port-0 to a separate port on the HBA. Software is Solaris-10U7_x86, patched current as of yesterday, and we've got all firmware up-to-date as well (including that from CAM-6.4.1.5, for SIM's and disks). Solaris-10_x86 driver: MPT HBA driver v1.85 LSI 1068E p/n: 375-3487-04 LSI 1068E BIOS: 6.26.00.00 (2008.10.14) LSI 1068E f/w: 1.26.00.00-IT SIM firmware: 3R21 drives: SEAGATE ST35000N-3AZY So, all should be compatible with mpt's multipathing, and mpt.conf has the mpxio-disable="no" and disable-sata-mpxio="no" settings. We've let "smtsboot -e" do its thing, but multipathing is not working -- the system continues to see 48 drives. And yes, it's clear that drive 0 is identical to drive 24, etc. The GUID's from "raidctl -l -g 0.0.0 0" and "raidctl -l -g 0.24.0 0" are identical. So, what magic might we be missing?
