Hi, people, I'm trying to launch a nice server on IBM Blade, and encountered =20 serious problem with multipath via Qlogic/ISP driver. I have IBM blade with two fibre channel adapters: isp0, isp1: <Qlogic ISP 2422 PCI FC-AL Adapter> Also i have storage IBM DS3400 with 2 FC-RAID controllers. Each =20 adapter has link to each FC-RAID. On the storage, I've created two logical disks (big disk 10G and small =20 one 6G), assigned to my blade, and sucessfully installed freebsd-8.0-amd64 on device da0. As expected, camcontrol shows da0-da7 devices (2 logical disks with 4 =20 pathes to each one). camcontrol readcap reports da0, da2, da4, da6 - belongs to 10G drive and da1, da3, da5, da7 - has 6G. Then I tried to build multipath volume on da1,da3,da5,da7. End here =20 problem starts: camcontrol inquiry da0 -S reports SX80801049 (which is actually serial =20 number of raid controller at DS3400, not an ID of 10G volume) camcontrol inquiry da1 -S also reports SX80801049... camcontrol inquiry da2 -S reports serial of second RAID (instead of =20 the same ID as da0)... and so on... camcontrol inquiry da4 -S reports first RAID serial (fine, this one =20 through isp1). In logs a lot of "ILLEGAL REQUEST asc:94,1" regarding da1, da2, da5, da6. As you can see, it allows me to have only one logical storage per RAID =20 controller :)) Help please. Thanks in advance. -- best regards, Andriy Kopystyansky ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.
