How to fix BOOTP ERROR: TFTP of first block failed, ABORT

I was attempting booting a NIM client from a new NIM master. The following message was displayed on the console while attempting to tftp the client info file:

Client LPAR

While checking on the nimserver notice that tftp daemons are inoperative.

root@nimserver(/)# lssrc -a |grep tftp

 tftpd            tcpip                         inoperative

root@nimserver(/)#

root@nimserver(/)# stopsrc -s tftpd

0513-004 The Subsystem or Group, tftpd, is currently inoperative.

root@nimserver(/)#

root@nimserver(/)# startsrc -s tftpd

0513-059 The tftpd Subsystem has been started. Subsystem PID is 82108.

root@nimserver(/)#

root@nimserver(/)# lssrc -a |grep tftp

 tftpd            tcpip            82108        active

root@nimserver(/)#

This fix the problem, when an attempt made again to boot from nimserver and this time it is successful.
