rdev<br />

rdev1-rdev2<br />

Privilege Class: B<br />

Use the QUERY DUPLEX comm<strong>and</strong> to display the status of duplex pairs of devices<br />

attached to the 3990-3 <strong>and</strong> 3990-6 storage subsystem.<br />

rdev<br />

rdev1-rdev2<br />

is the real device number, a list of real device numbers, or a range of real<br />

device numbers of the primary or secondary volumes in the established duplex<br />

pairs.<br />

1. The device number of either the primary or secondary volume in a duplex pair<br />

may be specified on this comm<strong>and</strong>.<br />

2. This comm<strong>and</strong> may be issued to offline devices.<br />

3. If both the primary <strong>and</strong> secondary of a duplex pair are included in the device list<br />

or device range, two identical responses will be displayed.<br />

Response 1:<br />

Duplex pair (prdev,srdev) - active<br />

This response is displayed for each duplex pair that is not in suspended duplex<br />

state <strong>and</strong> for which synchronization is not in progress.<br />

When <strong>CP</strong> is running in a guest virtual machine, hyphens (----) will appear in the<br />

srdev position if the secondary volume is not in the guest’s <strong>CP</strong> I/O configuration.<br />

prdev<br />

is the real device number of the primary volume in the duplex pair.<br />

srdev<br />

is the real device number of the secondary volume in the duplex pair.<br />

Response 2:<br />

Duplex pair (prdev,srdev) - copy operation<br />

is in progress.<br />

QUERY DUPLEX<br />

This response is displayed for each duplex pair that is in the process of being<br />

synchronized.<br />
