Figure 32 FlashCopy Information Dialog Box

The FlashCopy Information dialog box has the following features:

• Total relationships displays the number of relationships that are already established by FlashCopy

Mirror V2 (on the left side of the slash ( / )), and the total number of relationships that can be

established by FlashCopy Mirror V2 (on the right side of the slash ( / )).

• Remaining relationship(s) displays the remaining number of relationships that can be established

by FlashCopy Mirror V2.

NOTE:

The number displayed in Remaining relationship(s) is the number which can be calculated by

subtracting the total number of FlashCopy Mirror V2 relationships and XP Snapshot pairs that are

already established or created from the total number of relationships that can be established.

• Total differential tables displays the number of differential tables that are already used by

FlashCopy Mirror V2 (on the left side of the slash ( / )), and the total number of differential tables

in the disk storage system (on the right side of the slash ( / )).

• Remaining differential table(s) displays the remaining number of differential tables in the disk

storage system.

NOTE:

InadditiontoFlashCopyMirrorV2,XPBusinessCopy,Siz,FlexCopyXP,XPSnapshot,andXPAuto

LUN use differential tables. Therefore, if Hitachi ShadowImage, Siz, XP Snapshot, and/or Flex Copy

XP pairs exist, or migration plans are being executed by XP Auto LUN, you may be able to establish

fewer numbers of relationships than the total number of relationships.

• Rela

tionship Expansion displays the status of the relationship expansion function which has been

set by FlashCopy Mirror V2: Enable or Disable.
