Solaris 11 in Maintenence mode: nfs mount: : RPC: Rpcbind failure - RPC: Unable to receive

There is an issue with Solaris 11 machine and it boots automatically to the single user mode.We can see the error message "**nfs mount: : RPC: Rpcbind failure - RPC: Unable to receive"**. The machine is a LDom . I booted through OS Image and found that there was an entry in vfstab corresponding to the same. It was removed and tried to start the server again but still the same. I cross checked and there was no entries in dfstab.As in attached image we can see that the network milestone is maintenance mode. Kindly guide me what further investigation and action need to be taken as this is an critical server and need to solve the issue asap. Kindly let me know if any further info required.
