Table 6-3 Detailed Information Display Items for RANK
Displays icons and numbers of RANKs. Display format of the icon is the same as that of the
Configuration Display Area.
Displays the Busy Ratio of RANKs. For the RANK that does not have valid Busy Ratio information,
an asterisk (***) is displayed.
Note: When a logical disk in the RANK is moved, Busy Ratio information which has been
accumulated is no longer related with Busy Ratio information which is to be accumulated after
the movement. Therefore, immediately after a logical disk has been moved, there is no valid
Busy Ratio information for the RANK. This state will be cancelled when Busy Ratio
information is accumulated at the next interval.
Displays the time when the transfer of the last logical disk in the RANK has been completed. When
logical disks are not moved, "Un-carrying" is displayed.
Displays the RAID type of the RANK.
Ready ....... Indicates that the RANK is in the normal state.
Attn ....... Indicates that an event (reduce, formatting, etc.) is occurring in the RANK and
attention is necessary.
Fault ....... Indicates that a fault is occurring in the RANK. When "fault" is displayed, logical
disks in the RANK cannot be moved.
