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

Procedure

  1. 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.

    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
    
  2. 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.

    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.
