Defect fixes

Restrictions and Known Problems

  • For AIX diskless nodes, the xcatmaster attribute in the database must be an ip address of the Service Node as known by the node. The current NIM creation of a diskless image builds the /etc/hosts file with only the long hostname of the service node, so putting a short hostname in the xcatmaster attribute will not resolve on the node. If there is no hierarchy, then the site table master attribute is used and that also must be the ip address of the Management Node as known by the nodes. This affects the setup of syslog and node to node passwordless ssh support on the AIX diskless nodes during install.
