Windows - go into Disk Administrator and hit rescan

ESX - use vSphere go to ESX server, configuration tab, add storage

AIX - cfgmgr

John,

can't remember from the top but they are all documented in Host Connectivity guides for each platform

LUN ID has always been a 2 byte hex value. 00-ff, for a total of 256.
For LUN ID used 2 byte hex value,  LUN ID may be from 0 to 255, total 256, but LUN ID 0 used for controller.
It correct for all OS. For vSphere you can read vSphere Configuration Maximums.

hi

If we mapped & Masked to a LPAR in VIO servers ( we use NPIV WWPN) we have to run vxdctl -enable.

Thanks

why would you run vxdctl -enable unless you run Veritas LVM ?
