HP XP Racks - Manual (Page 22)

The following are examples of when you can perform a CG pair-split based on status of the BC
pairs in the CG:
•
Example 1
The are six BC pairs in a CG. Two of the pairs are paired (“PAIR” status), two are in
“COPY(PD)/COPY” status, and two are in “PSUS” status. In this case, you can perform a CG
pair-split, and doing so changes the status of all of the pairs in the CG to “PSUS”.
•
Example 2
There are two BC pairs in a CG and one is paired (“PAIR” status) and the other is in the
process of being resynchronized (“COPY(RS)/COPY” status). In this case, you cannot perform
a CG pair-split.
•
Example 3
The are six BC pairs in a CG. Two of the pairs are paired (“PAIR” status), two are in the
process of Quick Split (“PSUS(SP)/PSUS” status), and two are in “PSUE” status. In this case,
the CG pair-split ends abnormally and the status of all of the pairs in the CG remains the
same.
