NIS Address Resolution Hangs and Causes Failure to Fail Over (6257112)

Problem Summary: In the Solaris 10 OS, the /etc/nsswitch.conf file has been modified to include NIS in the ipnodes entry.

ipnodes:    files nis [NOTFOUND=return]

This causes the address resolution to hang if NIS becomes inaccessible, either due to a NIS problem or due to failure of all public network adapters. This problem eventually causes failover resources or shared address resources to fail to fail over.

Workaround: Complete the following before you create logical host or shared address resources:

1. Change the ipnodes entry in the /etc/nsswitch.conf file from [NOTFOUND=return] to [TRYAGAIN=0].

   ipnodes: files nis [TRYAGAIN=0]

2. Ensure that all IP addresses for logical hosts and shared addresses are added to the /etc/inet/ipnodes file, in addition to the /etc/inet/hosts file.
