redundancy tab not visible

[Cees_3]

Hi,
I am setting up several Proliants with QLA2340 HBA's and one MSA1000. Each server gets its own LUN, but with a double FC connection. I have configured the LUN's, used SSP to connect the LUN's to one server and I see the disks apear in Diskmanagement (2x the same lun off course). Now I need Multipath to make one redundant connection, so I installed HP MPIO basic DSM for MSA1000/MSA1500 active-passive disk arrays, version 1.40. After the reboot I see the Multipath 'adapter' apear under SCSI devices in device manager, but the disks have disappeared in diskmanagement. Searching the install guides, I now have to install the HP Proliant Smart Array Device manager extension for Windows 2000/2003, but with the last Smartpack 7.70A installation this was already done. So, I should have now a Redundacy tab on my HBA to configure Multipath. But there isn't one. Am I missing something? I hope someone can help, because I think it is only one tiny little thing...

Thanks!
Cees
