HP XP P9000 Continuous Access Synchronous for Mainframe Systems User Guide

Example 1: more initial copies than previously specified
In this example, four initial copies are being created in the same operation, but Maximum Initial
Copy Activities is set at 2. In this scenario, the Priority field in the Add Pair (Synchronous) dialog
box would be set as shown in the following table.
Value set for PriorityP-VOL
2LDEV 00
3LDEV 01
1LDEV 02
4LDEV 03
The order for the initial copy and the Priority for the P-VOLs are shown in the following table.
Value set for PriorityP-VOLOrder for initial copy
1LDEV 021
2LDEV 002
3LDEV 013
4LDEV 034
In this case, because the value of Maximum Initial Copy Activities is 2, initial copy operations for
LDEV 02 and LDEV 00 are started. If either one of the initial copy operations for LDEV 02 and
LDEV 00 is completed, the initial copy for LDEV 01 is started.
Example 2: initial copy started, new pairs added
The following table shows the Priority value when the initial copy is already begun and then two
new pairs are added. The P-VOLs are for the new pairs
Value set for PriorityP-VOL
2LDEV 10
1LDEV 11
If initial copy is already started, and if a new initial copy is added, the additional initial copy is
started after the previously performed initial copy is completed. The priority of all the initial copy
operations being performed is shown in the following table.
