If there are security SSH or xCAT keys or certificates problems, proceed with the following
steps:
2. Verify whether
xdsh <node> date
runs without prompting for password.
3. Run the
updatenode -k
command to update the keys or certificates on the nodes as
shown in Example 4-3.
Example 4-3 To update the security keys for the node “
c250f06c10ap01
”
# updatenode c250f06c10ap01 -V -k
Enter the password for the userid: root on the node where the ssh keys
will be updated:

Running command on c250mgrs38-pvt: ifconfig -a| grep "inet" 2>&1
Running internal xCAT command: makeknownhosts ...
Running command on c250mgrs38-pvt: cat //.ssh/known_hosts >

Running command on c250mgrs38-pvt: cat /tmp/7013302 > //.ssh/known_hosts 2>&1
Running command on c250mgrs38-pvt: rm -f /tmp/7013302 2>&1
