Oracle RAC upgrade test is performed in the test environment today. The original version is 11.2.0.3.0 and you want to upgrade it to 11.2.0.4.0, however, during the runinstaller process, [INS-06006] Passwordless SSH connectivity not set up between the following nodes (s): [rac01] is encountered.
Run ssh rac01 date and ssh rac02 date on both nodes;
Then the machine name in the/etc/hosts file is modified, and all the machine names are changed to lowercase letters. the problem persists;
Finally, Setup is selected in "SSH Connectivity" and can be installed normally, but the Test still has the same error.
For example:
Later, we found the (Doc ID 1597212.1) solution in MOS as follows:
Go to the Grid account and run the following command:
$ <OLD_GI_HOME>/oui/bin/runInstaller-updateNodelist ORACLE_HOME = <OLD_GI_HOME> "CLUSTER_NODES = {racnode1, racnode2}" CRS = true
For example, run the following command:
[Root @ rac01 ~] #Su-grid
[Grid @ rac01 grid] $Cd/u01/app/11.2.0/grid/oui/bin/
[Grid @ rac01 bin] $./RunInstaller-updateNodelist ORACLE_HOME =/u01/app/11.2.0/grid "CLUSTER_NODES = rac01, rac02" CRS = true

'Updatenodelist' was successful.
After the preceding command is executed, run [grid @ Oracle-LAB grid] $./runInstaller again.
Then, you will find that the Node Name is changed from uppercase to lowercase, and then "Next.
