Summary

If a network configuration is not properly configured for a vServer, this will cause errors when you add a STORAGE_CTL node to the DPX Enterprise.

 

 

Symptoms

 

 

An “IO Exception” error message displays when a STORAGE_CTL node is added to the DPX Enterprise.

 

 

 

Resolution

 

 

  1. Check to see that SVM's option, SSL Server Authentication Enabled, is set to true and that an SSL Certificate is assigned.

 

 

              a. ssl show -vserver svm-name
              b. security certificate show -instance -vserver svm-name
              c. Example common to enable: security ssl modify -vserver svm-name -ca name.cert -serial 5A5A5A5A -server-enabled tru

  1. Check if any aggregate is assigned to the vServer.
    1. Run “vserver show –vserver <NameOfVserver> –fields aggr-list” to check if any aggregate is assigned.
    2. If not, run “vserver modify –vserver <NameOfVserver> -aggr_list <NamesOfAggregatesSeparatedByComma>” to add aggregate(s).
  2. Check if iSCSI is enabled.
    1. Run “vserver iscsi interface show” to check if an interface is enabled for iSCSI on the vserver.
    2. Run “vserver iscsi show” to check if iSCSI service is enabled.
  3. Check firewall policies.
    1. By default, a firewall policy for http and https on a data vserver is enabled. In order to add a vserver to DPX enterprise, a firewall policy for http and https should be enabled.
    2. Run “system services firewall policy show” to see what policies disable firewall for http and https.
    3. Run “network interface show –firewall-policy <PolicyName>” to check what policy is assigned for the vserver. This step has to be repeated for each of firewall policies.
    4. You can create a new firewall policy which allows http or https, or assign an existing policy to a LIF on the vserver. The existing policy should allow http and https. If you decide to create a new policy, refer to the NetApp Clustered Data ONTAP System Administration Guide for Cluster Administrators.
    5. If necessary, run “network interface modify -vserver <VserverName> -lif <NameOfLIF> -firewall-policy <nameOfPolicy>” to assign a new policy to the LIF.
