Solution

For E25K System Controllers running System Management Services (SMS) 1.6 requires the JASS packages and patches installed on Solaris 10.

As we know the JASS script disables most of services for security reasons, so make sure to change the following in /etc/system and /etc/hosts.allow file to fix this problem:

1. Remove "set nfssrv:nfs_portmon=1" parameter from /etc/system
2. Add the line "rpcbind: all" in /etc/hosts.allow file

Also make sure the NFS 4 version is disabled on the System Controller running Solaris 10. Disabling NFS 4 version can be done by setting the NFS_SERVER_VERSMAX=3 in /etc/default/nfs file. After these changes reboot the System controller where the Solaris jumpstart server is setup.

Additional Information
It is possible to disable NFS 4 during installation of Solaris 10. There will be a question at the end of Solaris 10 installation

"Do you want to enable NFS version 4 ? "

Answer "no" to this question.
