Preparing the cluster for transition
Contributors Download PDF of this page
Before transition, you must prepare the cluster to communicate with the 7-Mode Transition Tool and prepare the SVMs for transition. You can transition to a target HA pair that has data aggregates.
The cluster must already be set up and the target cluster nodes must be joined to the cluster.
The SVMs must be created and assigned to an IPspace.
You can transition the 7-Mode disk shelves to a target HA pair that has preexisting data aggregates and volumes.
For a two-node cluster, you must have a data aggregate to host the root volumes of the target SVMs. For a cluster with four or more nodes, the root volumes of the SVMs can be hosted either on the target nodes of the transition or on other nodes in the cluster.
You should not upgrade the cluster to a different ONTAP version during transition.
|You can upgrade the cluster to a patch release of the same ONTAP version, if required.|
From an administration host, verify that the cluster is reachable by using the cluster-management LIF:
Enable SSLv3 or FIPS on the cluster:
If you want to enable… Enter…
system services web modify -sslv3-enabled true
FIPS 140-2 compliance
system services web modify -ssl-fips-enabled true
When FIPS 140-2 compliance is enabled, SSLv3 is disabled. ONTAP prevents you from enabling SSLv3 when FIPS 140-2 compliance is enabled. If you enable FIPS 140-2 and then subsequently disable it, SSLv3 remains disabled.
The best practice is to enable FIPS because of the security vulnerabilities in SSLv3.
Verify that HTTPS is allowed on the cluster management LIF:
View the firewall policy for the cluster management LIF:
network interface show -vserver svm_name -lif cluster_mgmt_lif -fields firewall-policy
cluster1::> network interface show -vserver cluster1 -lif cluster_mgmt -fields firewall-policy vserver lif firewall-policy ------- ------------ --------------- cluster1 cluster_mgmt mgmt
Verify that the firewall policy associated with the cluster management LIF allows HTTPS access:
system services firewall policy show -policy mgmt
cluster1::> system services firewall policy show -policy mgmt Policy Service Action IP-List ---------------- ---------- ------ -------------------- mgmt dns allow 0.0.0.0/0, ::/0 http allow 0.0.0.0/0, ::/0 https allow 0.0.0.0/0, ::/0 ndmp allow 0.0.0.0/0, ::/0 ntp allow 0.0.0.0/0, ::/0 rsh deny 0.0.0.0/0, ::/0 snmp allow 0.0.0.0/0, ::/0 ssh allow 0.0.0.0/0, ::/0 telnet deny 0.0.0.0/0, ::/0 9 entries were displayed.
