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.
