134 Changing Asynchronous Mirroring Settings
Changing
Asynchronous
Mirroring
Settings The
set asyncMirrorGroup
command enables you to change the property
settings for an asynchronous mirrored pair. Use this command to change these
property settings:

Synchronization interval – The length of time between automatically sending
updates of modified data from the local storage array to the remote storage array.

Synchronization warning threshold – The length of time to wait until a warning is
triggered when the synchronization of volumes takes longer than the defined
time.

Recovery warning threshold – The length of time to wait until a warning is
triggered when the automatic data update for the point-in-time image on the
remote storage array is older than a defined time.

Warning threshold percent – The percent of capacity of the mirror repository
volume at which a warning is sent if the mirror repository volume is nearing full.

User label – A new name for the asynchronous mirror group.

Automatic resynchronization – A setting to enable or disable automatic
resynchronization between the primary volume and the secondary volume.

Volume – A repository volume for which you want to increase the capacity.

Repository volume – An unused repository volume that you want to add to
another repository volume to increase capacity.

Role – A setting to change the role, primary or secondary, of the volumes in an
asynchronous mirror group.

Force – The setting to force a role change on the local storage array if the link
between the local storage array and the remote storage array is not available.

No synchronization – A setting to force synchronization before a role change.
This example shows how to use the
set asyncMirrorGroup
command to
increase the capacity of a repository volume:
c:\...\sm X \client>smcli 123.45.67.88 123.45.67.89

-c “set asyncMirrorGroup \"amg_001\"

volume="\repos_006\" increaseRepositoryCapacity

repositoryVolumes=("\repos_0020\" "\repos_0021\");”
This example shows how to use the command in a script file:
set asyncMirrorGroup "amg_001"

volume="repos_006" increaseRepositoryCapacity

repositoryVolumes=("repos_0020" "repos_0021");
