[Symptom1]

The pre_upgrade_check fails on a specific node cn27(192.168.4.14):

[06/21/2019 14:15:42 2583513] ERROR (upgrade_utils:1062) [Password Check] FAILED: The check failed on cn.
Failed to verify Compute Node host password on 192.168.4.14.

[06/21/2019 14:17:11 2583513] ERROR (upgrade_utils:1062) [OS Check] FAILED: The check failed on the following nodes: ['ovcacn27r1'].
Unable to contact compute node: ovcacn27r1.

But verify_pw.py shows password matches:

| system-root : |

| : ovcacn27r1 ip 192.168.4.14 exists |
| : connect as user root to 192.168.4.14 |
| : 192.168.4.14 password matches |

Issue happened on only cn27, other CN nodes all passed password checks.

Also "wallet -b /nfs/shared_storage/wallet/user -q system-root" shows correct password which could be used for ssh login.

The pre_upgrade_check fails on PCA internal Cisco switches with "Authentication failure"

But manually ssh login PCA internal Cisco switches succeed without any issue.
