    This means the SRL usage is 0 - if rlink was behind then it would say SRL has X bytes outstanding and give percentage - you can test this by downing network.  

    Note also, that vxrlink status will also show you if rlink is using DCM (if SRL overflows, or in autosync, or after running a takeover)

    To watch rlink catching up, then a good command to run is:
    vxrlink -i 5 status 

    so you can see how much the SRL or DCM is draining every 5 seconds.

    Have you had a look at 'vxrlink status' ?

    It also shows SRL status.

    Extract from VVR Admin Guide:

    Syntax for vxrlink status command

     

    vxrlink [-g <diskgroup>] [-r <rvg>] [-i <interval>] \[-t <timestamp>] [-T] status <rlink>
     
    Example:
    vxrlink -i1 -t 10 -T status rlink_sec_host
    The output resembles:
    4/6/2005 11:38:21 AM
    RLINK is up to date.
    RLINK is up to date.
    RLINK has 47 outstanding writes, occupying less than 1%
    (2994 Kbytes) of the
    Replicator Log.

    RLINK has 101 outstanding writes, occupying less than 1%
    (6371 Kbytes) of the
    Replicator Log.
    RLINK rlink_sec_host is behind by 0 hrs 0 mins 15 secs

    Good idea to keep small cmd window open so that the command (with -i <sec>) can keep on running.
    (Similar to 'ping -t'  that we use to keep on pinging another machine.) 

    As you can see the sample output in the manual (with -i <sec> also gives 2 cycles of :
    RLINK is up to date.
    and then shows     outstanding writes in the next cycle  (meaning some activity occurred at this point in time).

    But unfortunately that command should be run on Primary Node unlike Linux we can run the repstatus command on any Site Active Node

    The fact that "vradmin repstatus" is not available in Windows is a pain and I don't know why this is the case.
