Figure 38 Information Dialog Box
The following information displays in the Information dialog box:
ShadowImage for Mainframe pair(s)
The number of SIz pairs displays in the format of XXXX / YYYY. XXXX indicates the number
of SIz pairs, and YYYY indicates the total number of SIz pair tables, and ShadowImage for
Mainframe pair tables.
The maximum number of pairs that can be created in one storage system is 16,384, including
migration plans and relationships. Therefore, if XP pairs, migration plans of XP Auto LUN,
and relationships of FlashCopy Mirroring and FlashCopy Mirroring V2 are created in the
same storage system, the maximum number of pairs that you can create may be less than
16,384 minus YYYY.
When the volume size is large, ShadowImage for Mainframe uses multiple pair tables per
one pair. Therefore, sometimes you cannot create 16,384 pairs. For information about the
number of pairs and the pair tables, see
