Wang, That didn't seem to work! (though it might have been because i already removed all references to that image from the tables) [root@xcat ~]# rmvm vmmaster1 -p Error: Invalid nodes and/or groups in noderange: vmmaster1 [root@xcat ~]#
So i tried doing it for another master image i had created and...this is what happens: [root@xcat moab]# tabdump vmmaster #name,os,arch,profile,storage,storagemodel,nics,vintage,originator,comments,disable "vmmaster02","centos5.5","x86_64","compute","nfs://xcat.core.cloud/vms/shared",,"eth0","Sun Jul 24 12:10:49 2011","root",, [root@xcat moab]# tabdump vm #node,host,migrationdest,storage,storagemodel,cfgstore,memory,cpus,nics,nicmodel,bootorder,clockoffset,virtflags,master,vncport,textconsole,powerstate,beacon,datacenter,guestostype,othersettings,vidmodel,vidproto,comments,disable "clonevm01","blade03",,"nfs://xcat.core.cloud/vms/shared",,"nfs://xcat.core.cloud/vms/shared","2048","2","eth0",,,,,"vmmaster02",,,,,"vlan5",,,,,"VM cloned from vm10", [root@xcat moab]# rmvm vmmaster02 -p Error: Invalid nodes and/or groups in noderange: vmmaster02 [root@xcat moab]# Any thoughts on how i should remove it?? I also tried with "rmnimimage" (as someone had suggested in this mailing list) but still no luck: [root@xcat moab]# rmnimimage vmmaster02 Error: 'vmmaster02' is not a valid xCAT image name. Error: Return=1. [root@xcat moab]# What is the correct approach to remove a master image?
