Problems with HPUX Virtual Machine and IBM SDD SW. No More Than 24LUNs are Configured

www.unixbabuforum.inWe are working in the install of a rx6600 with HPUX Virtual Machine in order to config two guest servers running HPUX 11.31v3. Since Virtual Machine runs HPUX 11.23v2 and our SAN is based on an IBM SVC we have installed latest available version of IBM SDD SW and havce assigned 36 LUNs to the VM host. 
Not able to configure more than 24 LUNs. When running datapath query devices: 

bmhpvm01:/tmp> datapath query device | more 

Total Devices : 24 

Dev#: 0 Device

www.unixbabuforum.inIt's a problem with HPUX 11.23v2 that uses SCSI-2 to address up to 8 LUN ids (from 0 to 7). This issue is fixed in HPUX 11.32v3 but due to HPVM runs on top of 11.23 solution was to modify the host in the IBM SVC config and set it as an HPUX host (i didn't know that) and that's it. Now i can see my 16 LUNs assigned (or 32 devices with datapath commands).
