26.11.6 Pause Global Mirror session
Use the pausegmir command to pause Global Mirror processing. This allows you to
temporarily suspend Global Mirror processing attempts to form consistency groups, for the
specified session. The syntax of the pausegmir command is as follows:
dscli pausegmir -lss <Master LSS ID> -session <session_ID> -cfg <Master device
configuration file>
<Master_Control_Path_LSS_ID>:<Subordinate_Control_Path_LSS_ID> ...
One reason you would pause a Global Mirror session is to make modifications to the Global
Mirror tuning parameters, because these parameters can be modified when you resume the
session. See 26.11.7, “Resume Global Mirror session” on page 399.
Example 26-64 shows the result of pausing the Global Mirror session 01. This session
consisted only of a Master (no Subordinates), which was running in LSS 65 on the storage
image at site 1.
Example 26-64 pausegmir with Master only
dscli pausegmir -lss 65 -session 01 -cfg $DSCLI/profile/DS-01.profile

To visualize the paused Global Mirror session, use the command showgmir as discussed in

Example 26-62 and Example 26-63 on page 398.
26.11.7 Resume Global Mirror session
The resumegmir command resumes Global Mirror processing for a specified session. If you
have issued a pausegmir command to pause Global Mirror processing, issue the resumegmir
command to continue Global Mirror processing. The syntax of the resumegmir command is
as follows:
