You can use the SnapMirror options to specify different SnapMirror options for a system.
system_A> options snapmirror.enable snapmirror.enable on
You can use the options snapmirror command to view the values for the SnapMirror options.
Similarly, you can use the options replication command to view the values for the replication options.
The following table lists the SnapMirror options that you can use, along with their corresponding functions:
Option | Function | Default value |
---|---|---|
snapmirror.enable {on|off} | Specifies whether
SnapMirror is enabled for the system Alternatively, you can use the snapmirror on and snapmirror off commands. Attention: After changing the
snapmirror.enable option to
off, you should wait for at least 60 seconds before changing the option back to
on. This ensures that all subsequent
SnapMirror transfers work.
|
off |
snapmirror.access host=list list is a comma-separated list of the host names of allowed systems. |
Specifies the
SnapMirror destinations that are allowed to copy from the system You can also use the /etc/snapmirror.allow file to specify the allowed destinations. However, using the snapmirror.access option is the preferred method. When the option is set to legacy, access is controlled by the /etc/snapmirror.allow file. Note: If both the
snapmirror.access option and the
/etc/snapmirror.allow file are used, the
snapmirror.access option takes precedence. This can affect the initialization of
SnapMirror relationships.
|
legacy |
snapmirror.log.enable {on|off} | Specifies whether SnapMirror activity is logged in the /etc/log/snapmirror.x files | on |
replication.volume. use_auto_resync {on|off} |
Specifies automatic resynchronization for synchronous SnapMirror relationships | off |
replication.volume. reserved_transfers n |
Specifies the number of reserved transfers for
SnapMirror volumes
n is a variable number, and depends on the system model. |
0 |
replication.logical. reserved_transfers n |
Specifies the number of reserved transfers for
SnapVault and
SnapMirror qtrees n is a variable number, and depends on the system model. |
0 |
snapmirror.volume.local_nwk_bypass.enable | Specifies whether local Snapmirror transfer optimization is enabled Note: If this option is set to
on, the
replication.throttle.enable option and the
snapmirror throttle
option settings will not have an impact on SnapMirror transfers within the same system.
