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
Terminology and functionality differ somewhat between the RM CLI
interface and the RC GUI 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
