7. Install the Mokum Oracle VM Diagnostic Utilities

Applicable to all Oracle VM 3.x Releases. 
The Mokum Oracle VM Server Diagnostic Utilities are a collection of diagnostic, and operations scripts for Oracle VM Server 3.x.. To install, simply unzip the file on your Oracle VM server in /root, chmod 755 -R mokum_oracle_vm_server_diagnostic_utilities7-21-2014, and run the scripts from the mokum_oracle_vm_server_diagnostic_utilities-7-21-2014 directory.
For exmaple, first unzip the file as show in the example below:
# unzip
chmod 755 -R mokum_oracle_vm_server_diagnostic_utilities7-21-2014
This will create a subdirectory mokum_oracle_vm_server_diagnostic_utilities-7-21-2014 which contains 8 scripts.
# cd mokum_oracle_vm_server_diagnostic_utilities7-21-2014
# ll
To run any of the scripts, as root, type ./script_name, i.e. ./ would print a list to stdout of all of the virtual machines, templates and assemblies within a server pool.
Note: If a previous version of Mokum Oracle VM server Diagnostic Utilities already is installed, it is highly recommended to remove this rm -rf mokum_oracle_vm_server_diagnostic_utilities-DATE prior to installing the new version.
When opening a Virtual Machine console using Oracle VM Manager, if the VNC console opens with “Status: Connected to Server” and no VNC console, run blank_vnc_console_fix to remove the broken ovm-consoled pid and start the ovm-consoled service. 
To be able to reuse an Oracle VM Server in a new or existing server pool, run clean_cluster to wipe the Oracle VM Server's berkeley DB and cluster data before discovering in Oracle VM Manager.
To troubleshoot berkeley DB and cluster issues run cluster_health to generate a status report named  hostname-date-cluster_health.out.
To troubleshoot Fibre Channel HBA issues run fcscan_details to generate a status report on multipath and HBA details named hostname-date-san-details.out.
list_vms will print a list to stdout of all of the virtual machines, templates and assemblies within a server pool.
uuid_to_vm generates xm list output with uuid to simple name mappings to stdout.
local_bench will run a simple dd test in the /tmp directory on local disk and output to hostname-date-local_bench.out.
ocfs2_bench will run a simple dd test for Oracle VM repositories (LUNS) and outputs to local_bench.out. Note: It is necessary to edit/change the path to dd test each desired repository.
