RELATED IDEAS

add option for the tgtread status

See this idea on ideas.ibm.com

We are using CSM on open system to manage zOS LPAR. When we create replication, the option tgtread is at yes with CSM, which is not compatible with zOS.

Can you add a checkbox to manage this option?

    Hello.
    Thanks for your comment.
    We are in mainframe environnement, and tgtread should never be activated.
    I would add that for a better solution, CSM should detect CDK volumes and not activate this option in this case.

    Antony.

    We'll consider the request but is there a particular use case that requires the inhibit tgt read option? Would help with prioritization to understand as we haven't seen this request before.

    We do have a workaround that can be used for now however, as long as inhibit tgt read is for all pairs in the environment. If you create a file named "preventReadFromSecondary" in the following CSM install directory, then every time CSM does an establish of a PPRC pair, we will set the options on the pair to inhibit tgt reads. NOTE there's no file type in the name...CSM simply looks to see if the file exists.

    <csm_install>/liberty/wlp/usr/servers/csmServer/etc/preventReadFromSecondary
