Creating multipath device with FC Disks
Hello,

I am trying to setup a storage server with salvaged equipments:
QSSC-S4R server, with QLogic 2562 FC HBA's
Clariion KTN-STL4 4GB FC Enclosures
Disks Salvaged from EMC Vmax

Disks are 520B sector size so i converted to 512B in linux environment and create multipath successfully. But in solaris, it doesnt create any multipath devices

Code:
root@replica:~# mpathadm list lu
root@replica:~# 

root@replica:~# luxadm probe

Any way to create multipath device manually?

Thanks.
