Paired CA volume status definitions

Each pair of CA volumes consists of a primary volume (P-VOL) and
secondary volume (S-VOL). Each pair has six possible paired statuses.

The major CA pair statuses are:

• SMPL

• PAIR

• COPY

• PSUS

• PSUE

• PFUS

The P-VOL controls the status for the pair, which is reflected in the status
of the S-VOL. When you issue a CA command, the status usually changes.
A read or write request from the host is allowed or rejected, depending on
the status of the paired volume, as shown in the figure on the next page.

Caution

The BC and CA Remote Console based GUI has different terminology and
functionality from the RM interface. For instance:

• The terms “suspend” and “split” may have opposite meanings

• S-VOL read/write options while suspended may differ

• The GUI allows you to choose/force a PSUE state
