Thanks A. Bellinger.
Which kernel version does it support NodeACLs + MappedLUNs logic function? How to configure this function? Any reference documents?

Shuo

The NodeACLs + MappedLUNs logic as-is allow for different initiators to see different LUN masking views on the same storage endpoint.
Eg, a single FC WWPN and it's default LUN layout under configfs /sys/kernel/config/target/qla2xxx/$WWPN/$TPGT/lun/$LUN_ID/ can appear to each $HOST_WWPN with any arbitrary mapping under /sys/kernel/config/target/qla2xxx/$WWPN/$TPGT/acls/$HOST_WWPN/$LUN_ID/
