VTrak M310p, M210p Product Manual

Logical Drive PDM

Predictive Data Migration (PDM) is the migration of data from the suspect disk drive to a spare disk drive, similar to Rebuilding a Logical Drive. But unlike Rebuilding, PDM constantly monitors your disk drives, and automatically copies your data to a spare disk drive before the disk drive fails and your Logical Drive goes Critical. See “Predictive Data Migration (PDM)” on page 199.

To run PDM:

1.Click the Subsystem icon in Tree View.

2.Click on the Background Activities tab in Management View.

3.From the Background Activities dropdown menu, select Start PDM.

4.From the Source Physical Drive dropdown menu, select a Source disk array.

5.From the Target Physical Drive dropdown menu, select a Target physical drive.

6.Click on the Submit button.

A PDM link appears on the Background Activities tab and the percent completed displays.

To set PDM priority, see “Change Background Settings” on page 50.

Logical Drive Check Table

The Logical Drive–Check Table tab enables you to view error tables. Use this information to evaluate the integrity of the logical drive and to determine whether corrective action is needed. To View the tables:

1.Click the Subsystem icon in Tree View.

2.Click on the Disk Arrays icon.

3.Click on the Disk Array icon.

4.Click on the Logical Drives icon

5.Click on the Logical Drive icon.

6.Click the Check Table tab in Management view.

7.Click the option for the table you want to see. The default is All tables.

If there are entries, they are listed as follows:

•Entry Number – A number assigned to each block of entry.

•Table Type – Read Check, Write Check or Inconsistent Block (see below).

•Start Logical Block Address – LBA of the first block for this entry.
