Applying scanner policies in MetroCluster configurations

A scanner policy determines whether a scanner pool is active. You must apply a scanner policy to the primary and secondary scanner pools on each cluster in a MetroCluster configuration.

About this task

You can apply only one scanner policy to a scanner pool.
If you created a scanner pool for all of the SVMs in a cluster, you must apply a scanner policy on each SVM individually.

Apply a scanner policy: vserver vscan scanner-pool apply-policy -vserver data_SVM -scanner-pool scanner_pool -scanner-policy primary|secondary|idle -cluster cluster_to_apply_policy_on
A scanner policy can have one of the following values:
- Primary specifies that the scanner pool is active.
- Secondary specifies that the scanner pool is active only if none of the Vscan servers in the primary scanner pool is connected.
- Idle specifies that the scanner pool is inactive.
Important
You must apply all scanner policies from the cluster containing the primary SVM.
Example
The following commands apply scanner policies to the primary and secondary scanner pools on each cluster in a MetroCluster configuration:
cluster1::>vserver vscan scanner-pool apply-policy -vserver cifssvm1 -scanner-pool pool1_for_site1 -scanner-policy primary -cluster cluster1 cluster1::>vserver vscan scanner-pool apply-policy -vserver cifssvm1 -scanner-pool pool2_for_site1 -scanner-policy secondary -cluster cluster1 cluster1::>vserver vscan scanner-pool apply-policy -vserver cifssvm1 -scanner-pool pool1_for_site2 -scanner-policy secondary -cluster cluster2 cluster1::>vserver vscan scanner-pool apply-policy -vserver cifssvm1 -scanner-pool pool2_for_site2 -scanner-policy primary -cluster cluster2

Verify that the scanner pool is active: vserver vscan scanner-pool show -vserver data_SVM|cluster_admin_SVM -scanner-pool scanner_pool

For a complete list of options, see the man page for the command.

Example

The following command displays the details for the scanner pool pool1 :

cluster1::> vserver vscan scanner-pool show -vserver cifssvm1 -scanner-pool pool1_for_site1

                                    Vserver: cifssvm1
                               Scanner Pool: pool1_for_site1
                             Applied Policy: primary
                             Current Status: on
         Cluster on Which Policy Is Applied: cluster1
                  Scanner Pool Config Owner: vserver
       List of IPs of Allowed Vscan Servers: 
List of Host Names of Allowed Vscan Servers: scan1
                   List of Privileged Users: cifs\u1,cifs\u2

You can use the vserver vscan scanner-pool show-active command to view the active scanner pools on an SVM. For complete command syntax, see the man page for the command.
