SnapDrive on HPUX fails


I’m trying to get snapdrive working a HPUX  11.31 Itanium.  I using  running SnapDrive 4.1.1 and fcp host utilities 4.3.   I have other luns on this host to the  same filer  not though SnapDrive working  working fine.   I am using ALUA as the multipathing and I did  enable it ALUA on the igroup.

I also sent the multipathing in the SnapDrive.conf as PVLINKS is this correct?

uxwpeng8:/opt/NetApp/snapdrive# snapdrive storage create -lun -lunsize 10m

Add the filer systemname to the /etc/hosts file, i believe the sanlun returns the system name and SDU is not able to map the IP with the system name.
