Pairs in the same consistency group must be in PAIR/Duplex status when you begin the split operation in order to maintain consistency. Otherwise, when the operation completes, pair status will be inconsistent.
This is shown in the following table, in which font angle indicates the following:
- Italics font: Pair status before the split operation on the consistency group
- Regular font: Status after the split operation
For CCI
