route: socket: Host is down , set ndd parameter

[subodhbagade]

Hello Experts , 

Need your valuable inputs,

I have HP-UX 11iv3 running on RX6600 , facing some NFS issue , NFS FS gets hanged at server

Due to NFS issue multiple production client system gets impacted we able unmount on 11.31 forcefully but not able to unmount NFS on 11.11 ?  umount -f does not work

So we rebooted this NFS server to get rid of NFS issues but it get stuck at nfs.core during system startup so rebooted system into single user mode changed the nfs_core , ngs_client ,, nfs_server to 0 and able to boot .

But now it is not coming up on network 

sockfd error: : Host is down
ERROR: Failed to set ndd tunable parameters
ERROR: lan1 interface: ifconfig: socket: Host is down
ERROR: lan7 interface: ifconfig: socket: Host is down
ERROR: route: socket: Host is down

Also continueously getting pop up 

INIT: Command is respawning too rapidly.
Will try again in 5 minutes.
Check for possible errors.

Checked the rc.log  ,getting below error

#ndd -get  /dev/tcp ? |grep rex

No o/p 

I have other system it shows 

#ndd -get  /dev/tcp ? |grep rex

tcp_rexmit_interval_max (read and write)
tcp_rexmit_interval_min (read and write)
tcp_rexmit_interval_initial (read and write)
tcp_rexmit_interval_initial_lnp(read and write)

How to bring it on network ? Production is highly impacted 

Thanks in advance
