Wats would be the best way to disable link based IPMP on the fly without loosing network connectivity ?
use "ipmp_adm" to disable the unwanted connection... (don't remenber if this is the right command... but it was something like this!)
i just checked on my virtual solaris. the command is "if_mpadm".
There is no command ipmp_adm and if_mpadm is for attaching and detaching the interface to test if IPMP is working fine or not .. not for disabling it 
# ifconfig interface-name group ""
will remove interface from IPMP group
Yep got it thanx .. and do i need to kill in.mpath daemon ?
the if_mpadm command with option -d disables a nic which is in an ipmp group. i can't find in your post that you were trying to unconfigure your group! be more specific and the answers will be more specific ;).
Sorry for the confusion but i 'm just trying to remove the IPMP configured on my system without restarting network services or reboot of the system
