    With HACMP, when using disk heartbeat, is it a pre-requisite to be in vg concurrent mode?

    Or we can use heartbeat disk with a share vg too?

    Hi -

    to do disk heartbeating, HACMP requires the VG to be an "enhanced concurrent vg" with concurrency turned off. This is the only way to do disk heartbeating.

    For reference see the "Planning Guide" for your version of HACMP at:

    See http://publib.boulder.ibm.com/infocenter/clresctr/vxrx/topic/com.ibm.cluster.hacmp.doc/hacmpbooks.html
    Thanks,

    Where exactly did you find that we need to turned off the concurrency?
    I don't find it in the HACMP Guide....
