[zfs-discuss] Eliminating double path with ZFS's volume manager
Hi, Since they have installed a second path to our Hitachi SAN, my Mac OS X Server 4.8 mounts every SAN disk twice. I asked everywhere, if there's a way, to correct that. And the only answer so far was, that I need a volume manager, that can be configured to consider two volumes as being identical. Now that Mac OS X Leopard supports ZFS, could using ZFS be the solution for this problem? If yes, how could I achieve this? Thanks for your help!

Go poke around in the multipath Xsan storage pool properties. Specifies how Xsan uses multiple Fibre Channel paths between clients and storage. This is the equiv of Veritas DMP or [whatever we now call] Solaris MPxIO You mean, I should find some configuration file? Well, I can't find one. Nothing like 'scsi_vhci.conf'.

I belive it's definitely possible to just correct your config under Mac OS without any need to use other fs or volume manager, however going to zfs could be a good idea anyway That implies that MacOS has some sort of native SCSI multipathing like Solaris Mpxio. Does such a beast exist? That's exactly the question. I'm not aware of any. The only such thing, could be in Xsan. But we don't have Xsan here; we have Hitachi. And this tool called 'Xsan Admin' is not freely available and the person at the Apple Support said, it wouldn't help in my case.

Looks like its got a half-way decent multipath design: http://docs.info.apple.com/article.html?path=Xsan/1.1/ en/c3xs12.html Great, but that is with Xsan. If I don't exchange our Hitachi with an Xsan, I don't have this 'cvadmin'.
