The tiers’ total and available capacities are shown under the “Capacity” and “Space Available”
columns respectively.
Disk Status shows the status of each disk on the tier as follows:
• A letter <ABCDEFGHPS> represents a healthy disk at that location.
• A space indicates that the disk is not present or detected.
• A period (.) denotes that the disk was failed by the system.
• The symbol “?” indicates that the disk has failed the diagnostic tests or is not configured
correctly.
• The character “r” indicates that the disk was failed by the system and replaced by a spare disk.
• The symbol “!” indicates that the disk is in the wrong location.
NOTE : The rate of rebuild and format operations can be adjusted with the commands, Tier Delay=x
and Tier Extent=x.

Use the tier config command to display the detailed disk configuration information for all of the tiers
( Figure 2-17).
