● consistency-group set-detach-rule no-automatic-winner
● consistency-group set-detach-rule winner
Use the set command to modify the following properties of a consistency group:
● Visibility
● Storage-at-clusters
● Local-read-override
To display which attributes are modifiable (writable) using the set command and their valid inputs:
VPlexcli:/clusters/cluster-1/consistency-groups/TestCG> set
attribute input-description
-------------------
-----------------------------------------------------------------------------------------
--------
active-clusters Read-only.
cache-mode Read-only.
detach-rule Read-only.
name Takes a unique, non-empty and non-null name. A valid name starts
with a letter or '_'
and contains only letters, numbers, '-' and '_'.
operational-status Read-only.
passive-clusters Read-only.
read-only Takes one of '0', '1', 'f', 'false', 'n', 'no', 'off', 'on', 't',
'true', 'y', 'yes' (not case sensitive).
storage-at-clusters Takes a list with each element being a 'cluster' context or a
context pattern.
virtual-volumes Read-only.
visibility Takes a list with each element being a 'cluster' context or a
context pattern.
To display the current setting of a property:
VPlexcli:/> set /clusters/cluster-1/consistency-groups/TestCG::cache-mode
To display the default values for the target consistency group:
VPlexcli:/clusters/cluster-1/consistency-groups/TestCG> set --default
attribute default-value
-------------------- -----------------
active-clusters No default value.
cache-mode synchronous.
detach-rule No default value.
name No default value.
operational-status No default value.
passive-clusters No default value.
read-only No default value.
storage-at-clusters No default value.
virtual-volumes No default value.
visibility No default value.
Example of modify: set visibility
To change the visibility property from the target consistency group context:
About this task
VPlexcli:/clusters/cluster-1/consistency-groups/TestCG> set visibility
cluster-1,cluster-2
To change the visibility property from the consistency group context:
VPlexcli:/clusters/cluster-1/consistency-groups> set TestCG::visibility
cluster-1,cluster-2
