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
- 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
- Check if any aggregate is assigned to the vServer.
- Run “vserver show –vserver <NameOfVserver> –fields aggr-list” to check if any aggregate is assigned.
- If not, run “vserver modify –vserver <NameOfVserver> -aggr_list <NamesOfAggregatesSeparatedByComma>” to add aggregate(s).
- Check if iSCSI is enabled.
- Run “vserver iscsi interface show” to check if an interface is enabled for iSCSI on the vserver.
- Run “vserver iscsi show” to check if iSCSI service is enabled.
- Check firewall policies.
- 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.
- Run “system services firewall policy show” to see what policies disable firewall for http and https.
- 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.
- 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.
- If necessary, run “network interface modify -vserver <VserverName> -lif <NameOfLIF> -firewall-policy <nameOfPolicy>” to assign a new policy to the LIF.
