Hi All, We are thinking of attempting a non-destructive change of NSD server node names in a Lenovo DSS cluster (DSS level 1.2a, which has Scale 4.2.3.5). For a non-GNR cluster, changing a node name for an NSD server isn't a huge deal if you can have a backup server serve up disks; one can mmdelnode then mmaddnode, for instance.
Has anyone tried to rename the NSD servers in a GNR cluster, however? I am not sure if it's as easy as failing over the recovery group, and deleting/adding the NSD server. It's easy enough to modify xcat. Perhaps mmchrecoverygroup can be used to change the RG names (since they are named after the NSD servers), but that might not be necessary. Or, it might not work - does anyone know if there is a special process to change NSD server names in an E( or D or G)SS cluster that does not run afoul of GNR or upgrade scripts? Best regards, Keith
