Solution 2282051.1 : Exalogic Virtual: Receiving "Switch Status Has Switched To FAULTED" for the Management Switch After Installing the April 2017 PSU 2.0.6.2.170418

Applies to:

Oracle Exalogic Elastic Cloud Software - Version 2.0.6.2.170418 to 2.0.6.2.170418
Exalogic Elastic Cloud X3-2 Quarter Rack - Version X3 to X3 [Release X3]
Linux x86-64
Oracle Virtual Server x86-64

Symptoms

After updating Exalogic Virtual rack to the April 2017 PSU, EMOC is throwing alert, "Switch status has switched to FAULTED", despite no errors shown on the Cisco switch. After acknowledgement/removal, the alert recurs.

Changes

Passwords for the Management switch are not default.

Cause

This issue is caused due to having incorrect credentials in EMOC for Cisco Management Switch.

NOTE: Cause for incorrect credentials in EMOC might have happened because of manual updates to the credentials with incorrect passwords (or) the passwords on the Cisco Management Switch were updated, but the same were not updated in EMOC level.

Proper credential can be verified by running following scripts on the EMOC vserver:

/usr/bin/expect /opt/sun/n1gc/bin/cisco_check_ssh.expect -cred /tmp/creds -host <cisco_ip>

echo $?
3 <===== looking for status of 3

/usr/bin/expect /opt/sun/n1gc/bin/cisco_config_comm.expect -cred /tmp/creds -host <cisco_ip>

In above example /tmp/creds file content will be in this format:

admin
<admin_password>
<enable_password>
public

Solution

To resolve this issue create a new credentials for the Cisco Management Switch component in EMOC using following steps

Login to EMOC BUI console as root user
Go to Assets accordion on the left and expand Exalogic rack -> Switches and Click on Cisco Management Switch.
On the right hand side click on "Update Management Credentials". Following is the screenshot of EMOC page which highlights Cisco Switch Asset, its description and "Update Management Credentials" option.
Click on "Create a new set of credentials" and provide credentials.
