Symptoms

Errors below are shown in the PowerFlex Manager UI:

  • Invalid credentials request, old credentials, and new credentials are the same or unchanged. (VXFM00685)
  • Could not be connected through SSH due to an unexpected SSH connection error. (VXFM00445)

Deployment job logs show error:

  • Error discovering, jobId=<job-ID>
  • Discovery by IP range failed for device: serviceTag *** cannot be discovered because Puppet module scaleio was not available or failed to return the device information.

 

Cause

Changing the password in the existing OS Admin credential does not update the node root password on the node. PowerFlex manager still needs this credential to match the existing root password in order to connect to the node to run the password change command.

 

Resolution

Follow the PowerFlex Administration guide Updating passwords for nodes section to modify the password for the supported method.

Updating passwords for nodes

Note: Do not edit the old credentials having the correct password instead, create a new one with the new password, PFMP must have both the old correct password and the new password, each in a separate credential entry.
