i have a V480 running sol8 with latest patches running sun SAN4.4
its connected thru 2 qlogic 2300 hbas to a sun 6320 san.
it has 4 luns from the 6320 san, each is 50gb
i have mpxio enabled.

when i boot up i see 3 of my disks are "online" and the fourth is "standby"

can anyone tell me why this might of happened and how to fix it?

i think it can be fixed using "luxadm failover" command but im not sure.

also with the luxadm failover command effect my many other hosts connected
to the 6320 san? i dont want the other hosts to lose disk connectivity.

here is the message i see in /var/adm/messages:
