Table 1 describes the status of a volume.
| Volume pair status . . . | Description . . . |
|---|---|
| COPY | A volume pair that XRC is currently synchronizing. Volume pairs in COPY status are not part of the XRC session and, are therefore, not eligible for recovery. XRC does not consider copy volume pairs during ERRORLEVEL processing, nor does it include them during XRECOVER and XADVANCE processing. |
| DUPLEX | A volume pair for which volume synchronization or resynchronization has completed and that has been successfully recovered, or that was established with the NOCOPY option. The pair is active, and is neither SUSPENDED, PENDING, nor in COPY status. The volume pair is consistent up to the session-specified timestamp reported in message ANTQ8231I. |
| PENDING | A volume pair that XRC has not yet synchronized or resynchronized. Volume pairs in PENDING status are not part of the XRC session and, are therefore, not eligible for recovery. XRC does not consider a volume pair in PENDING status during ERRORLEVEL processing, nor does it include the volume pair during XRECOVER and XADVANCE command processing. |
| SEQCHECK | A volume pair that contains nontimestamped writes. This temporary condition indicates that data consistency is uncertain, for this volume pair, in the event of a disaster recovery. The pair automatically returns to the DUPLEX status when XRC successfully writes a timestamped update to the secondary volume. |
| SUSPENDED | An established volume pair in an XRC session where XRC is no longer copying data from the primary volume to the secondary volume. The volume pair remains in the XRC session. |
