Promise VTrak: Fourth SAS-connected Expansion Chassis Only: Xsan (Data Only) configuration script

This article contains a script used to configure Promise VTrak SAS-connected Expansion Chassis for Xsan. This script is used in the event that a Promise VTrak RAID Controller has already been configured for use with Xsan, and that an Expansion Chassis is being connected to the already-configured RAID Controller.

To create the configuration script, copy the text below beginning with the line "#Begin Copy" to the line "#End Copy" and paste the text into TextEdit, using these guidelines. Once you've created the script, follow the guidelines in this article to import the configuration script.
