Multibus Failover, Linux and HBA |
|
|
Hallo...
is there an HBA capable of doing automatic failover in Linux over a multibus
failover configuration (multipath) in order to avoid use of
securepath,veritas devicemapper software?
thank you |

No, because itīs not the HBA who does the fail-over but an
application/driver above. AFAIK there is no MPIO-Feature from a Linux
distribution like the Windows MPIO-feature. Tru64 and OVMS have the feature
embedded in the OS.

Qlogic has MPIO drivers and software that you can download that works
with their FC HBAs only. There is no load balancing capability, but
it most definately provides path failover. I believe Emulex also
now has such drivers.
YOu can also configure the LINUX md device driver to do MPIO, but I've
seen info from people saying it really doesn't work unless you run 2.6
kernel.

I'm writing them just now!

Umh... are you sure you are not speaking about "dm" (device mapper) instead
of md ?
thanks...

We utilize SecurePath software from HP. This software provide
automated failover for the HBA.
