srdev<br />

is the real device number of the volume that was the secondary volume of the<br />

duplex pair.<br />

userid<br />

is the ID of the user who issued the comm<strong>and</strong>.<br />

XXXXXX<br />

is volume identification label.<br />

Response 5:<br />

srdev Changing of volume label has failed.<br />

This response is displayed when the DUPLEX ON or DUPLEX OFF comm<strong>and</strong><br />

cannot specify a new volume identification label for the former secondary volume of<br />

the duplex pair.<br />

where:<br />

srdev<br />

is the real device number of the volume that was the secondary volume of the<br />

duplex pair.<br />

Response 6:<br />

Duplex pair (prdev,srdev) - not established<br />

because cache <strong>and</strong>/or non-volatile storage is not available.<br />

This response is generated when DUPLEX ON is issued <strong>and</strong> cache <strong>and</strong>/or NVS<br />

was not available to the subsystem.<br />

where:<br />

prdev<br />

is the real device number of the volume specified as the primary volume of the<br />

duplex pair.<br />

srdev<br />

is the real device number of the volume specified as the secondary volume of<br />

the duplex pair.<br />

Response 7:<br />
