4.3.2.5 How to configure wide port checker
This feature is applicable for SAS drives instead of SATA drives. If there is no
connection with any active SAS initiator by checking all wide ports, AIC Expander
Controller stops all attached SAS drives to save power consumption of SAS drives.
Otherwise, AIC Expander Controller starts all attached SAS drives to provide drive
access service to any active SAS initiator. The same setting should be applied to HUB
and EGDE.
( A ) Get the current state of wide port checker
cmd> check_wide_port

( B ) Enable checking wide port. The new setting will take effect after
reset.
cmd> check_wide_port on
cmd> reset
( C ) Disable checking wide port. The new setting will take effect after
reset.
