Hello, I hope to be in the right list. my question is the following. I can''t seem to get multipathing configure on XCP 1.6. In XenCenter I was able to enable "Multipath" however, in the LUN under general tab I see " multipath 1 of 1 active", the the CLI I do the following command xe --m node session it list only one session. Can someone help me please? Thanks in

Hello, I have IBM Storwize V3700 storage, connected to 2 IBM x3550 M4 servers via fiber channel. The servers are with QLogic ISP2532-based 8Gb Fibre Channel to PCI Express HBA cards and run Centos 5.10 When I export a volume to the servers, each of them sees the volume twice, i.e /dev/sdb and /dev/sdc, with the same size. Previously I have installed many systems with IBM DS3500 series of
