    I haven't work on a 4.0g system in awhile and then when I did they were
    mostly scsi based so excuses me if this sounds like a dumb question.

    Does 4.0g support multibus fail over?

    I have a standalone ES40 with two KGPSA-CA's connected to two Compaq
    Storagework 16 EL's connected to an dual controller HSG80. The HSG80 is set
    up as transparent failover and not multibus.

    I have one emx controller going to one switch and the other emx controller
    going to the other switch just like I have set up before on 5.1b systems. I
    started running a disk exerciser and then pulled emx0, but the disk
    exerciser failed rather than failing over. Is this normal for 4.0g? Could it
    be because I don't have my HSG80's set up in multibus failover?

    I haven't installed any patches yet so if that will fix this I'll try it.

    It looks like emx1 is a separate bus from emx0 so to me it looks like 4.0g
    doesn't support failover, but I'm just trying to confirm.
