Setting load-balance="round-robin" will cause each path to the device 2N/A# to be used in turn. 2N/A# Automatic failback configuration 2N/A# possible values are auto-failback="enable" or auto-failback="disable" 2N/A#BEGIN: FAILOVER_MODULE_BLOCK (DO NOT MOVE OR DELETE) 2N/A# Declare scsi_vhci failover module paths with 'ddi-forceload' so that 2N/A# they get loaded early enough to be available for scsi_vhci root use. 2N/A# NOTE: Correct operation depends on the value of 'ddi-forceload', this 2N/A# value should not be changed. The ordering of entries is from 2N/A# most-specific failover modules (with a "probe" implementation that is 2N/A# completely VID/PID table based), to most generic (failover modules that 2N/A# are based on T10 standards like TPGS). By convention the last part of a 2N/A# failover module path, after "/scsi_vhci_", is called the 2N/A# "failover-module-name", which begins with "f_" (like "f_asym_sun"). The 2N/A# "failover-module-name" is also used in the override mechanism below. 2N/A# For a device that has a GUID, discovered on a pHCI with mpxio enabled, vHCI 2N/A# access also depends on one of the scsi_vhci failover modules accepting the 2N/A# device. The default way this occurs is by a failover module's "probe" 2N/A# implementation (sfo_device_probe) indicating the device is supported under 2N/A# scsi_vhci. To override this default probe-oriented configuration in 2N/A# 1) establish support for a device not currently accepted under scsi_vhci 2N/A# or 2) override the module selected by "probe" 2N/A# or 3) disable scsi_vhci support for a device 2N/A# you can add a 'scsi-vhci-failover-override' tuple, as documented in 2N/A# scsi_get_device_type_string(9F). For each tuple, the first part provides 2N/A# basic device identity information (vid/pid) and the second part selects 2N/A# the failover module by "failover-module-name". If you want to disable 2N/A# scsi_vhci support for a device, use the special failover-module-name "NONE". 2N/A# Currently, for each failover-module-name in 'scsi-vhci-failover-override' 2N/A# (except "NONE") there needs to be a 2N/A# "012345670123456789012345", "failover-module-name" or "NONE" 2N/A# "|-VID--||-----PID------|", 2N/A# scsi-vhci-failover-override = 2N/A# "STK FLEXLINE 400", "f_asym_lsi", 2N/A# "SUN T4", "f_tpgs", 2N/A# "CME XIRTEMMYS", "NONE"; 2N/A#END: FAILOVER_MODULE_BLOCK (DO NOT MOVE OR DELETE)
