Qlogic FC Multipath and engenio
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Dear List,
I have recently bought my first set of FC devices, and am having a
little trouble
configuring them to run correctly.
I have a multipath setup between my 2 port hba on each of my servers,
and my two
raid systems have 2 ports as well, all connected over 2 qlogic
switches (not connected
to each other). The raid systems are StorageTek boxes with then
engenio software - 9.15
This means, that each server see each disk twice.
I have just compiled a 2.6.15.2 kernel for this setup.
What do I need to do to run multipath? Does the qlogic (qla2xxx)
driver in the
vanilla kernel support multipath? If so, do I need to do something to
enable it?
Or do I need to use the one on the qlogic download pages?
Can I use udev to sort out my device names for me? or do I have to
use lvm2?
I don't need any of the other lvm features...
Engenio provides a 'RDAC' driver to do the multipath support - Do I
need this?
Can't the qla2xxx driver do this automagically? - and use udev to do
the mapping?
Hoping someone can shed a bit of light on this,
Thanks
Andrew
