Hi,

Not sure why there is a difference between the  mulitipath -ll & multiapth -v3 ouput ,for  IO queuing features disply,

i.e 
multipath  -v3 
asm1: pgfailback = -2 (controller setting) 
asm1: pgpolicy = multibus (controller setting) 
asm1: selector = round-robin 0 (internal default) 
asm1: features = 0 (internal default) 
asm1: hwhandler = 0 (internal default) 
asm1: rr_weight = 2 (config file default) 
asm1: minio = 100 (config file default) 
asm1: no_path_retry = 5 (config file default) 
pg_timeout = NONE (internal default) 
asm1: set ACT_NOTHING (map unchanged)

 
multiapth -ll 

asm1 (1HITACHI_770100720007) dm-9 HITACHI,DF600F 
[size=65G][features=1 queue_if_no_path][hwhandler=0] 
\_ round-robin 0 [prio=0][active] 
 \_ 0:0:0:7 sdh 8:112 [active][ready] 
 \_ 1:0:0:7 sdp 8:240 [active][ready]


So if we look at the features part , v3 output displays the correct info since in the config file  I have disabled queuing, but where as in -ll ouput it says queuing is enabled !!

Can some one provide more info on this ....
