Renaming a Disk Group and Volume Name in Cluster Volume Manager

Groups

mcogdg --- > mco1dg

Volume

mcog ----> mco1

While Running a Command, I was getting error that command needs to be executed on the master server

Three host:

test0031

test0030

test0029

test0029# vxdctl -c mode

mode: enabled: cluster active - SLAVE

master: test0031

So all command needs to run on the Master Server test0031

·         First, Stop the Access of user to the filesystem

·         Unmount the file system

·         Rename the volume

test0031# vxvol -g mcogdg stop mcog

VxVM vxvol ERROR V-5-1-1218 Volume mcog is already stopped

test0031# vxprint -htv mcog
