    Hi,

    We have 2 node AIX hacmp cluster in our environment(hacmp v 6.1).

    The resource group is Active on one node and passive on other node. The RG have one concurrent VG which is varied on in Active mode on active node and varied on in passive mode on passive node.

    The VG is made up of 1 LUN. We have already increased the size of LUN at VIO level and rna cfgmgr on AIX server. On AIX disk size is now updated but I haven't run chvg -g on concurrent VG yet.

    My question is how do I increase size of concurrent VG without bringing down the cluster? Please provide all steps necessary to carry out this.

    If cluster has to be brought down please let me know all steps necessary to do this change.

    Thanks in advance.
