The script will setup SSH connectivity from the host datarac1.localdomain to all
the remote hosts. After the script is executed, the user can use SSH to run
commands on the remote hosts or copy files between this host datarac1.localdomain
and the remote hosts without being prompted for passwords or confirmations.
NOTE 1:
As part of the setup procedure, this script will use ssh and scp to copy
files between the local host and the remote hosts. Since the script does not
store passwords, you may be prompted for the passwords during the execution of
the script whenever ssh or scp is invoked.
NOTE 2:
AS PER SSH REQUIREMENTS, THIS SCRIPT WILL SECURE THE USER HOME DIRECTORY
AND THE .ssh DIRECTORY BY REVOKING GROUP AND WORLD WRITE PRIVILEGES TO THESE
directories.

------------------------------------------------------------------------
Verifying SSH setup
===================
The script will now run the date command on the remote nodes using ssh
to verify if ssh is setup correctly. IF THE SETUP IS CORRECTLY SETUP,
THERE SHOULD BE NO OUTPUT OTHER THAN THE DATE AND SSH SHOULD NOT ASK FOR
PASSWORDS. If you see any output other than date or are prompted for the
password, ssh is not setup correctly and you will need to resolve the
issue and set up ssh again.
The possible causes for failure could be:
1. The server settings in /etc/ssh/sshd_config file do not allow ssh
for user oracle.
2. The server may have disabled public key based authentication.
3. The client public key on the server may be outdated.
4. ~oracle or ~oracle/.ssh on the remote host may not be owned by oracle.
5. User may not have passed -shared option for shared remote users or
may be passing the -shared option for non-shared remote users.
6. If there is output in addition to the date, but no password is asked,
it may be a security alert shown as part of company policy. Append the
additional text to the <OMS HOME>/sysman/prov/resources/ignoreMessages.txt file.

USAGE:
runcluvfy.sh stage -pre nodeadd -n <node_list>
[-vip <vip_list>] [-fixup] [-fixupnoexec]
[-method sudo -user <user_name> [-location <dir_path>]|-method root] [-verbose]
[-json] [-html]
[-save [-savedir <save_dir>]]
<vip_list> is the comma-separated list of virtual IP addresses that will be applied to the comma-separated list of non-domain qualified node names entered.
-json Specifies that the user wants the detailed report to be output in a JSON format. If the -json option is missing, then the detailed report is output in text to standard output format.
-html Specifies that the user wants the detailed report to be output in html format. If a browser recognized by CVU is available on the system, the results will be reported using that browser. Otherwise, the user will have to use -save option to get a copy of the report in html format which can be viewed by the user using a browser of his or her choice. If -html option is missing, then the detailed report is output in text format.
-save Specifies that the user wants the validation reports to be saved for future reference. The reports named cvucheckreport_<timestamp>.(htm|txt|json) as requested are saved in the location of the user's choice if specified using the -savedir option. If the -savedir option has not been specified, then the reports are saved in the default location <CV-HOME>/cv/report.
<node_list> is the comma-separated list of non-domain qualified node names which will be added to the cluster.
-method is the privilege delegation method, 'sudo' or 'root', to be used for root user access.
<user_name> is the user name to access all the nodes with root privileges.
<dir_path> is the full file system path for the 'sudo' executable.
DESCRIPTION:
Performs the appropriate checks on the nodes to be added to the existing cluster, and verifies the integrity of the cluster before the nodes can be added. If '-fixup' option is specified, on verification failure, fix up operations are performed if feasible. If '-fixupnoexec' option is specified, on verification failure, the fix up data will be generated and the instruction for manual execution of the generated fix ups will be displayed.
