right of an icon, the icon represents the parity group 1-3. If the text 1-3[1-4] appears on the right

of an icon, the icon represents two parity groups (that is, 1-3 and 1-4) that are connected together.

List: Information in the list differs depending on the item that you select in the tree.

When you select a class in the tree, the list displays information about parity groups in that class.

Figure 19 Information about Parity Groups

• PG indicates the parity group ID. The number before the hyphen (-) is the frame number. The

number after the hyphen is the group number.

The meaning of icons displayed here is the same as the icons in the tree.

Note:

If the indicated parity groups are the concatenated parity groups, this item only displays

the ID of the parity group at the top of the concatenated parity groups.

• HDD indicates the type of the hard disk drive.
• Ave. indicates the average usage rate for the parity group.

If an exclamation mark (!) is displayed, the reported usage rate is likely to be inaccurate,

because the configuration has changed (for example, volumes have been moved by Auto LUN

or changed by Virtual LVI or Open volume Management).

If a plus mark (+) is displayed before a usage rate 0, such as +0, the usage rate is not

completely 0 but less than 1.

• Max. indicates the maximum usage rate for the parity group.

If an exclamation mark (!) is displayed, the reported usage rate is likely to be inaccurate,

because the configuration has changed (for example, volumes have been moved by Auto LUN

or changed by Virtual LVI or Open Volume Management).

• Total indicates the total number of volumes in the parity group.
• Reserved indicates the number of reserved volumes.
• CLPR indicates the number and name of the CLPR corresponding to the parity group in the

format CLPR-number:CLPR-name. For details on CLPRs, see HP StorageWorks XP24000

Disk/Cache Partition User’s Guide.

When you select a parity group in the tree, the list displays information about volumes in that

parity group.

Figure 20 Information about Volumes in a Parity Group

• LDEV indicates the volume ID. The number on the left of the first colon (:) from the left is the

LDKC number. The number on the left of the second colon (:) from the left is the CU image

number. The number on the right of the second colon is the LDEV number.
