Nexus 1000v Error – “Operation could not be completed due to connection failure”

Cisco Nexus 1000v, network No Responses »

Rather non descriptive and annoying error when setting up a 1000v for the first time. You can also see the “HTTP/1.1 400 Bad Request” along with the error message.

Cause:

Incorrect port

You are connecting to a ESX server and no the vCenter server.

Resolution:

Change the port in vCenter to port 80.

‘Administration -> vCenter Server Settings -> Ports’

Point it to the correct vCenter server.

EMC UIM Web Interface – Authentication Error

UIM, Vblock No Responses »

If you receive an ‘authentication’ error when trying to log in as ‘sysadmin’ when trying to log in to the UIM web interface, then this is due to the sysadmin account being locked. This can be caused by entering an incorrect password more than 5 times although I have seen this happen off a straight reboot.

To resolve this issue:

Log in to the UIM server.
Open browser (assuming you have this available).
navigate to http://uim.local:8880/jmx-console.
In the filter box enter VC and click search.
Select service=SecurityService
Locate Void resetMasterAdminUser() and click invoke.

This will unlock the sysadmin user. It may also be worth restarting the vcmaster service to ensure that UIM picks up the unlocked account.
