You can display detailed data about unreadable sectors detected on the drives in your storage array.

The unreadable sectors log shows the most recent unreadable sector first. The log contains the following information about the volumes that contain the unreadable sectors. The fields are sortable.

Field Description

Affected Volume

Shows the label of the volume. If a missing volume contains unreadable sectors, the World Wide Identifier appears for the missing volume.

Logical Unit Number (LUN)

Shows the LUN for the volume. If the volume does not have a LUN, the dialog box shows NA.

Assigned To

Shows the hosts or host clusters that have access to the volume. If the volume is not accessible by a host, host cluster, or even a Default Cluster, the dialog box shows NA.
