22 Auto LUN XP for the XP128/XP1024
NOTE: If a host bus adapter’s WWN is displayed in red in the tree, the host bus adapter is connected to
two or more ports, but Performance Control does not control traffic between the HBA and some ports. For
information about controlling the traffic between the HBA and all connected ports, see ”Troubleshooting
Auto LUN XP” on page 36.
Port-LUN tab
This tab displays ports. The tree view displays the following icons.
NOTE: High-speed (2 port) mode is available only if the XP disk array has firmware version 21.06.22 or
later installed.
LDEV tab
This tab displays parity groups. Box folders appear below the Subsystem folder. The number at the end of
a Box folder name indicates the number at the beginning of the parity group ID. For example, if you
double-click the Box 1 folder, the tree view displays a list of parity groups that have IDs beginning with 1
(such as 1-1 and 1-2).
If you double-click a parity group, the logical volumes in the parity group appear in the table. If a parity
group ID starts with the letter E, the logical volumes in the parity group are external LUs.
The parity group icon ( ) represents a single parity group or two or more connected parity groups. If two
or more parity groups are connected, logical volumes can be striped across two or more drives. Therefore,
connected parity groups provide faster access (particularly faster sequential access) to data.
If the parity group icon represents a single parity group 1-3, the text 1-3 is displayed on the right of the
icon. If the parity group icon represents two or more connected parity groups, all connected parity groups
are displayed to the right of the icon. For example, if parity group 1-3 is connected with parity group 1-4,
