Is there any procedure to remove this down node from the Cluster without making it up.

Hello Jeet No Need to bring up the Down-Node in order to remove it from Cluster. Please refer the below Public document which have the steps to "Permanently remove a node from service in a cluster" https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c01058926 Hope this helps Br, PrakashPS

I am getting errors. will post the error soon.

Please find error and details. We have 4 node cluster and we need to remove one node from the existing cluster ( rsfo11i – node is a failover node and currently this node is down and unable to bring it back any more). I did create a new ascii file – “clconfig.ascii” without this (rsfo1i) node. Even I did create a new package conf file for all package and comment the line for node “rsfo11i. When I am trying to do checkconf and applyconf, getting below error. Please check and suggest what would be the next action plan to resolve the issue. NOTE : - on this 4 node, 6 packges running and all package is having failover to node “rsfo11i” – which need to have remove from the cluster. root # cmviewcl Warning: Unable to determine an IP address for rsfo11i: 2.

I would try to cmapplyconf the package configs "-P pkg_file.conf" first without also specifying the "-C <cluster_file.conf>" on the same command line. I see only two package config files on your cmcheckconf command line, are you sure you have reconfigured every package listed in the error output?

Thanks Mike for your reply..

Please find the bellow details ##

Here all package configuation files has been re- configured with excluding the down node which should be removed from cluster configuration file .

only two packages have the failover  node mentioed as rsfo11i.  for rest of the packages its not a failover node or someting but we have edited the configuration file to exculde this down node (rsfo11i).

As per your suggestion we tried but are  still getting the errors. Please do suggest.
