Archived - Promise VTrak: Replacement Controller Module configuration script
This article contains a script used to configure replacement Promise RAID Controller Modules.
If a Promise VTrak’s Controller Module is replaced, the replacement Controller Module’s default settings may not offer optimal performance and availability. To restore the settings that offer optimal performance and availability, create a script that will automatically configure the Controller Module’s settings.
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.
