To check the operating system version:

eclipse:root:/# oslevel -s 7100-00-03-1115

To check the UniVerse version:

eclipse:root:/# cd /u2/uv
eclipse:root:/u2/uv# uvregen -z
UniVerse Ver.: 11.1.4
Serial#......: 12345678
Expiry Date..: 1/1/2500
Max Logins...: 100
Device Licn..: Disabled
Conn per Dev.: 0

To get rid of the message, you can try running:

vgscan

Opening a Double-Take Support Case

If you are experiencing a problem with Double-Take, please follow this procedure to open a case with Double-Take Support:

First, gather the server logs and configuration details from both the source and destination servers. To do so, log in as root and run:

DTInfo.sh -f

This utility will gather your system information and create a compressed archive under /var/run/DT. Transfer this .tar.gz file to your workstation using your method of preference (i.e. FTP, SCP, samba, etc.).

Attach the file(s) to an email describing your problem to support@doubletake.com. You will receive an auto-response with a case number, and an engineer will respond shortly.
