Upgrading the VTS server
If you are upgrading from 6.03.x, you must upgrade to 6.04.01 before upgrading to 6.04.04.
Refer to the 6.04.01 Virtual TapeServer Operations and Administration Guide for information
about upgrading to 6.04.01. This guide can be found at
http://docs.hp.com/; search for “Virtual
Tape Server 6.04 Operations and Administration Guide”. Refer to the Upgrading VTS
appendix and be sure to review checklist of items to consider before beginning the upgrade
process. If necessary, contact your authorized service and support representative for
assistance.
Note If you have multiple VTS servers in your environment, it is recommended that you
upgrade all VTS servers.
During the upgrade, a backup of /usr/local/tape/ is created and upgrade and new operating
system RPMs are installed. After the upgrade completes, you can view the upgrade logs from
the Supervisory Functions page of the web interface.
