Configurations with Business Copy S-VOLs

P-VOL. This configuration requires that the Business Copy pair is split before the Continuous Access
Synchronous pair is created.

Status reporting, data currency

The following table indicates whose pair status is reported under different combinations of shared
volumes.
Continuous Access Synchronous pair status is reported to the host if you query the Continuous
Access Synchronous P-VOL or S-VOL. To obtain the Business Copy pair status, query the
Business Copy P-VOL pair.
Business Copy supports multiple S-VOLs for each of its P-VOLs, but when you issue a pair
status query, the status is returned only for the pair whose S-VOL has the lowest LUN. To check
pair status for the other S-VOLs, direct a host query to the specific S-VOL using the S-VOL's
LUN in the host command.
Remote Web Console displays the status of all S-VOLs associated with a Business Copy P-VOL.
