Analyzing the cause of VMware issues
If VMware is causing problems on the VCS host, you are initially recommended to collect logs from the host
for analysis:
for analysis:
1. Using the vSphere client (or the vCenter Server managing this ESXi host) connect to the ESXi host on
which the VCS is running.
2. Go to
File > Export > Export System logs
, choose the appropriate ESXi host and go with the default
settings.
After you have downloaded the logs analyze them, or have them analyzed to determine the issue.
More information on exporting logs can be found at

Restoring default configuration (factory reset)
Very rarely, it may become necessary to run the “factory-reset” script on your system. This reinstalls the
software image and resets the configuration to the functional minimum.
software image and resets the configuration to the functional minimum.
Prerequisite files
The factory-reset procedure described below rebuilds the system based on the most recent
successfully-installed software image. The files that are used for this reinstallation are stored in the
/mnt/harddisk/factory-reset/ folder on the system. These files are:

A text file containing just the 16-character Release Key, named rk

A file containing the software image in tar.gz format, named tandberg-image.tar.gz
In some cases (most commonly a fresh VM installation that has not been upgraded), these files will not be

Performing a reset to default configuration
The following procedure must be performed from the serial console or via a direct connection to the appliance
with a keyboard and monitor. This is because the network settings will be rewritten, so any SSH session
used to initiate the reset would be dropped and the output of the procedure would not be seen. The process
takes approximately 20 minutes.
