HP StorageWorks Continuous Track XP HP Continuous Track XP is a program in the system that detects and reports problems even before they are noticed by operators and users. HP Continuous Track XP "phones home" to the HP Storage Technology Center (STC), providing: • Periodic "well" checkups This checkup records the health of the disk array on a day-to-day basis. Every 24 hours, HP Continuous Track XP calls STC (your HP support representative sets the time of the call). When a successful connection is made, status information is transferred from the disk array to STC. If any configuration changes have been made, configuration information is also sent. • Incidental "sick" calls When an error occurs, a service information message (SIM) is generated, stored in the disk array for use by your HP support representative, and reported to STC.
