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 it´s 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. HTH Etti DoD #2503 |

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. David |

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

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