Hi. Having a F400 system. I have connected a vmwarecluster with 8 hosts and a Exchange 2007 CCR cluster. I have problems with path in Windows enviroment. In ESX hosts i see all 8 path to LUN. But in W2K8 i only see 4 path to LUN. The zooning is exactly the same for ESX as Windows. The persona for Win is 2 (customer runs Win2k8 NOT R2). Why the h*** do we not see all 8 path to LUN? And another thing is. On the 2 Exc2007 nodes we see the disks from each other Exc2007 in diskman (we set the volumes offline in diskmanager. We have 2 Exc2007 Nodes in 3Par and present 3 LUNS to each CCR node. CCRNODE1=3 LUNS CCRNODE2=3 LUNS And in zooning the are separeted....... Does anybody seen this Im realy confused /Bjorn |

Persona 2 enables ALUA, I use Persona 1 for all my 2003/2008 servers and clusters. To be honest, I've never had the need for ALUA so I don't know a whole lot about it. Make sure your Windows 2008 nodes have the MPIO role installed and configured for 3PAR.

question for 3PAR MPIO for ubuntu 12 I have ubuntu 12 server and need to hook up with a F400, is there any issue if i use the ubuntu native MPIO since there is no MPIO provide by 3PAR for ubuntu. Is there any concern on using the native MPIO? |

Disclaimer: I am no linux expert. While I believe it is possible for you to compile MPIO into your ubuntu... I believe the preferred method for multipathing in linux is "Device Mapper" and should already be part of the distro, no compiling required. https://help.ubuntu.com/12.04/servergui ... p-overview |

Richard is right - you should just need the bundled "multipathd" in Linux. The command "multipath -l" should show you the device, and the devices it uses as the different paths. |
