Clean installation on desktop with SATA controller suddenly ends up with multipathing being active.
I don't even know what it is :-(
It's usually for storage area networks where a disk may be accessed via multiple different paths, for redundancy. It has no place in a default openSUSE install.
You mean a machine accessing a single machine via two different cables and two chipsets? Also the hard disk has two sata ports?
Typically either with fibre, FoE or iSCSI. One storage host has two fibre HBAs, each connected to a fibre switch. The client has two fibres, each connected to a switch. A disk (e.g. an LVM logical volume) is now available over two separate paths. If an HBA fails in the storage host, or one of the fibre switches fail or an HBA fails in the client, there will still be a working path.
Wow. Makes a lot of sense, but I have not seen it. Not in my pay grade
You can set this up at home. 2nd hand fibre equipment is very cheap, but it's also easily done with ethernet. (if you want to play with it).
What device does Linux see then, /dev/what?
You can assign aliases, but otherwise /dev/mapper/<wwid>. -- Per Jessen, Zürich (20.4°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
