1. COPY status during initial copy.
2. COPY status during resynchronization.
3. After executing the pairsplit command on the FS or SS pair, you must confirm that all pairs in the FS or SS consistency
group are in PSUS status before performing the BC operation. This ensures that all snapshot data is consistent with P-VOL
data, and therefore is ready to use in the BC operation.
4. When the host accesses the FS or SS S-VOL, FS or SS P-VOL data may be used. Therefore you cannot perform a Quick Restore
to swap the BC P-VOL and S-VOLs.
Sharing the FS or SS primary volume with the BC secondary volume
The following table shows the pair operations that are supported when the BC S-VOL is shared
with an FS or SS P-VOL.

Data Retention
Access attributes and Business Copy operations
You can create BC pairs using volumes for which you set access attributes with Data Retention.
However, depending on the access attribute, BC pair operations and reserve attribute change
operations cannot be performed. The following tables show whether BC pair operations and reserve
attribute change operations can be performed for volumes for which access attributes are set with
Data Retention.
