SYSTEM WILL NOT START TCP/IP DEAMONS

Question:

ENV:  AIX 3.2.5, hacmp 3.1

DESC:  Customer's network was down and cluster node is not starting up
TCP/IP.

ACT:  Had customer do the following:
      lssrc -a  === only syslog and infod were running.
      startsrc -s portmap and got the following error
     
       Addr family not supported by protocol  
       portmapper cannot create socket

      Cannot ping self or any machine on the network.

      'ifconfig lo0' returned error:
      ifconfig: socket: Addr family not supprtd by protocol

      lsdev -Cc if === lo0, en0, en1 and tr0 were in a defined state
      netstat -i === only lo0 listed.

      I suggested that he runs fsck on the system.  Customer did not
      have bootable media, so I walked him thru creating bosboot 
      diskettes.   Had customer boot the system from the bosboot 
      diskettes and ran 'fsck' on all rootvg filesystems.  We found 
      no error messages.  We rebooted the system again in normal 
      mode, but tcpip daemons would not started.  

      chdev -l lo0 -a state=up  

      df ==== nothing was full.
      ifconfig lo0  === up and running.
      startsrc -s portmap
      startsrc -g tcpip
      startsrc -g nfs

      lsdev -Cc if === en0, en1 and tr0 showed as defined
      ifconfig en0 up
      ifconfig en1 up
      ifconfig tr0 up
      lsdev -Cc if === showed en0, en1 and tr0 showed available

      We started hacmp and the share volume group vary'ed on.

      We then rebooted the system and everything went back to the
      beginning.  

This provided a temporary solution for now.

Response:

Act:  I discovered that the /etc/rc.net had the wrong permissions and
that id didn't have the appropriate HACMP entries.  I had the customer
do the following on each node to correct the problem.

 1. /usr/sbin/cluster/utilities/clchipat false
 2. /usr/sbin/cluster/utilities/clchipate true
 3. chmod 750 /etc/rc.net
 4. smitty clstart
    --> restart
    --> cllockd = False
    --> clinfo = True
 5. shutdown -Fr

This resolved the problem on both nodes.

Response:

Closing with Customer Approval
