# Load balancing global configuration: setting load-balance="none" will cause
# all I/O to a given device (which supports multipath I/O) to occur via one
# path. Setting load-balance="round-robin" will cause each path to the device
# to be used in turn.

load-balance="round-robin";

# For enabling MPxIO support for 3rd party symmetric device need an
# entry similar to following in this file. Just replace the "SUN SENA"
# part with the Vendor ID/Product ID for the device, exactly as reported by
# Inquiry cmd.

# device-type-scsi-options-list =
# "SUN SENA", "symmetric-option";
