Solaris Multipathing (MPxIO/scsi_vhci) continues to send I/O on paths where command timeouts have occurred.
The following enhancement requests introduced the concept of least desired path for Solaris Multipathing (MPxIO/scsi_vhci) with Sun Common SCSI Architecture version 3 (SCSAv3) compliant drivers:
BUG 15638923 - SUNBT6947062 - PSARC/2011/029 Least Desired pkt_path_instance
BUG 15735699 - SUNBT7079597 - PSARC/2013/196 MPxIO: least desired path instance phase II
Fix delivered in Oracle Solaris 126.96.36.199.0 (or greater), Solaris 10 SPARC Patch ID 150400-14 (or greater), Solaris 10 x86 Patch ID 150401-14 (or greater).
Unfortunately, the Solaris Fibre Channel drivers are not SCSAv3 compliant, and due to complexity, the risks are considered too substantial for redesign at this time.
