hi,

the SAN HBA should be supported by the HP-UX,

Hitachi = HDLM

EMC = Powerpath

HP = SecurePath

HPUX 11.31 = have a new implementation of multipath software inside the OS.

Each vendor have ovn SW for multipathig.

Using ioscan -funC disk shows all the paths for all the disks. You can use sam to build vg and vgdisplay can show all the paths for each lv.

If you are using HP secure path

try

swlist |grep -i "secure" and look for secure path

secure path display

for emc
swlist |grep -i power and look for power path

powermt display dev=all

if using only hp alternate links
vgdiplay -v vg01 |grep -i "alternate links"
