To change the VMkernel interface ip I use this code snippet (tested on esx 3.0.x):

     /usr/bin/vimsh -n -e "hostsvc/net/vnic_remove $(/usr/bin/vimsh -n -e "hostsvc/net/vnic_info"|grep device|awk '{print $3}'|sed s/\"//g|sed s/\,//g)"
     /usr/bin/vimsh -n -e "hostsvc/net/vnic_add --ip-address=$vmkernelip --ip-subnet=$vmkernelsubnet VMkernel"
     /usr/bin/vimsh -n -e "hostsvc/vmotion/vnic_set $(/usr/bin/vimsh -n -e "hostsvc/net/vnic_info"|grep device|awk '{print $3}'|sed s/\"//g|sed s/\,//g)"

The variables $vmkernelip and $vmkernelsubnet have to be defined earlier in your script!

Today I tried to rename the local datastore on some esx 3.0.2 systems. Because I need a script to do this on many servers, I'm looking for a command on the cli (bash). I've some commands:

• vimsh -n -e "/hostsvc/datastore/rename oldname newname"

• ln -sf /vmfs/volumes/target /vmfs/volumes/newname && rm /vmfs/volumes/oldname

• mv /vmfs/volumes/oldname /vmfs/volumes/newname

vimsh produces no error, but nothing really happens. The same for ln. Calling mv to rename the link, I've got a message saying "... Function not implemented".

Any suggestions?

Annotation:I tried everything as root, no virtual machines were running and the server was in maintenance mode. To rename the datastore with vi-client was possible.
