Figure 12 History tab
Pane contents
This pane contains the following items:
• Monitoring Term: Displays the monitoring period specified in the Auto LUN pane, analyzes disk usage
information collected by Auto LUN XP during the monitoring period, and calculates estimated usage
rates of the source and target parity groups after a proposed volume migration.
• Gathering Time: Displays the time specified in the Auto LUN XP Monitoring Options pane. The disk
array collects usage statistics about resources (such as hard disk drives) at the specified gathering time.
Auto LUN XP uses the collected usage statistics to estimate usage rates of parity groups after a
proposed volume migration.
• Auto Migration History: Displays log information, showing the creation and execution of auto migration
plans. The Erase button erases the information.
• Migration History: Displays a log of volume migration events and a log or migration plan executed by
programs other than Auto LUN XP. The table displays the following information:
• Date: Event date
• Time: Event time
• Action: Description of migration operation or event
• Source[Parity PR.]: Source volume and parity group
• Destination: Target volume and parity group
• Owner: Program that reserved the volume. If Auto LUN XP reserved this volume, USP is displayed. If
another program reserved this volume, Other[XX] is displayed, where [XX] is the program ID.
