Command View XP or XP Remote Web Console window.
Physical tab
This tab displays parity groups, CHAs, DKAs, and other related items. 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.
In short range, if I/O workloads between hosts and the disk array become heavy, the disk array gives
higher priority to I/O processing than monitoring processing; therefore, some monitoring data might be
missing. If monitoring data is missing frequently, use the Gathering Interval option in the Monitoring
Options pane to increase the collection interval.

”Reserving target volumes” on page 31.
