Failure During Switch-Version: ERROR: Acquiring lock failed

Do you really want to switch between versions ?

Enter (yes/no)? yes
Switching Version and Restarting the Appliance …

Switch version duration can vary depending on the database size
and platform configuration. Please continue to monitor the
switchover process from here.
Waiting ……………………………………

Operation failed

ERROR: Acquiring lock failed

Easily solved with a simple reboot, then retry on the switch-version.

If this does fail, next steps would be:

  • Switch-version using Recovery CD
  • TAC case with Remote Account, and TAC to edit GRUB configuration file

VMware Tools 10.0 Update Failures Creates Outage – CSCux90747, CSCva09767, CSCuy84075

A friend hit this delightful defect this week:

 

 

There are several workarounds, but ultimately there’s a COP file for this – ciscocm.VMwareTools2016c.cop.sgn.  The attached defects cover several initial install and help-me-its-dead scenarios.

 

It’s a bit of a horror.  Watch out for those VMWare tools updates!

Accessing the jabber-config.xml Jabber Configuration File

Often when working on Cisco Jabber installations, you will be required to edit an existing jabber-config.xml file to change client parameters or support new functionality, or simply as part of an audit or system assessment want to have a look at what customization is being used for Jabber already.

There are several ways to access the jabber-config.xml file from your CUCM/TFTP server or Jabber client PC.

When troubleshooting, it is often helpful to know the methods to view from both the TFTP server and the Jabber client PC.  Discrepancies can be a good starting point for troubleshooting.

Method 1 – CUOS

From CUOS, run the following command:

admin:file view tftp jabber-config.xml

 

Method 2 – Browser

From your browser, enter the following:

http://X.X.X.X:6970/jabber-config.xml

where X.X.X.X is the CUCM (i.e. TFTP Server) IP Address

 

Method 3 – TFTP Client

Use a TFTP Client such as Windows TFTP client or TFTPD32 and GET the jabber-config.xml file.

 

Method 4 – Windows Client PC

Fetch this from the following path:

%USERPROFILE%\AppData\Roaming\Cisco\Unified Communications\Jabber\CSF\Config

You may need to enable showing of hidden files on the Windows desktop to reach this.

 

If you know of more, please let me know!
