如果用GUI的话，在把virtual volume加到storage view给主机时，应该可以手动配置LUN ID的吧。
In regards to the "Manually set LUNs for added Virtual Volumes" option, our VPLEX is at v5.0.1 and if we try to use this option, the LUN # which is specified is passed to the background command as "undefined" so we can't use this option. However, the error dialog box shows the actual VPLEXCLI command which is used and so we do it like this, from VPLEXCLI instead:
export storage-view addvirtualvolume --view /clusters/cluster-1/exports/storage-views/%storage view name% --virtual-volumes (%HLU#%,%virtual volume name%) --force
export storage-view addvirtualvolume --view /clusters/cluster-1/exports/storage-views/UCS_STJ_Production --virtual-volumes (5,device_VNX0038_LUN2002_1_vol) --force
We present both native VNX LUNs and VPLEX virtual volumes to the same ESXi clusters, so controlling the HLU (Host LUN ID #) is vital for us since we have room for error by accidentally presenting 2 of the same HLU to the hosts (nightmare! in VMware ESXi).
