NAME

acec query - Display the copy status of synchronous high-speed copying

SYNOPSIS

acec query -g COPY-GROUP [-p PAIR] [-r] [-progress] [-xml]

DESCRIPTION

This command displays the status of the synchronous high-speed copy for the specified copy group or copy pair.

OPTIONS

-g COPY-GROUP

This option specifies the copy group name.

-p PAIR

This option specifies a copy pair.

NOTES

• Information such as Copy direction data and SID data may display as "???".

  It is possible that the access path is incorrect. Therefore, check it using the "A.2.4 acarray detail (ETERNUS disk storage systems detail information display command)". For details on how to correctly set the access path, refer to "2.2.4 Access Path Settings".
