Record node2 information

Contributors Download PDF of this page

Before you can shut down and retire node2, you need to record information about its cluster network, management, and FC ports as well as its NVRAM System ID. You need that information later in the procedure when you map node2 to node4 and reassign disks.

Steps
  1. Find the cluster network, node-management, intercluster, and cluster-management ports on node2:

    network interface show -curr-node <node_name> -role cluster,intercluster,nodemgmt,cluster-mgmt

    The system displays the LIFs for that node and other nodes in the cluster, as shown in the following example:

    cluster::> network interface show -curr-node node2 -role
    cluster,intercluster,node-mgmt,cluster-mgmt
             Logical     Status     Network            Current     Current Is
    Vserver  Interface   Admin/Oper Address/Mask       Node        Port    Home
    -------- ----------  ---------- ------------------ ----------  ------- ----
    node2
             intercluster up/up     192.168.1.202/24   node2       e0e     true
             clus1        up/up     169.254.xx.xx/24   node2       e0a     true
             clus2        up/up     169.254.xx.xx/24   node2       e0b     true
             mgmt1        up/up     192.168.0.xxx/24   node2       e0c     true
    4 entries were displayed.
    Note Your system might not have intercluster LIFs. You will have a cluster management LIF only on one node of a node pair. A cluster management LIF was displayed in the example output of Step 1 in Record node1 port information.
  2. Capture the information in the output to use in the section Map ports from node2 to node4.

    The output information is required to map the new controller ports to the old controller ports.

  3. Determine physical ports on node2:

    network port show -node <node_name> -type physical +

    node_name is the node which is being migrated.

    The system displays the physical ports on node2, as shown in the following example:

    cluster::> network port show -node node2 -type physical
    
                                                                 Speed (Mbps)
    Node   Port      IPspace      Broadcast Domain Link   MTU    Admin/Oper
    ------ --------- ------------ ---------------- ----- ------- -----------
    node2
           e0M       Default      IP_address       up       1500  auto/100
           e0a       Default      -                up       1500  auto/1000
           e0b       Default      -                up       1500  auto/1000
           e1a       Cluster      Cluster          up       9000  auto/10000
           e1b       Cluster      Cluster          up       9000  auto/10000
    5 entries were displayed.
  4. Record the ports and their broadcast domains.

    The broadcast domains will need to be mapped to the ports on the new controller later in the procedure.

  5. Determine the FC ports on node2:

    network fcp adapter show

    The system displays the FC ports on the node2, as shown in the following example:

    cluster::> network fcp adapter show -node node2
                         Connection  Host
    Node         Adapter Established Port Address
    ------------ ------- ----------- ------------
    node2
                 0a      ptp         11400
    node2
                 0c      ptp         11700
    node2
                 6a      loop        0
    node2
                 6b      loop        0
    4 entries were displayed.
  6. Record the ports.

    The output information is required to map the new FC ports on the new controller later in the procedure.

  7. If you have not done so earlier, check whether there are interface groups or VLANs configured on node2:

    ifgrp show

    vlan show

    You will use the information in the section Map ports from node2 to node4.

  8. Take one of the following actions:

    If you…​ Then…​

    Recorded NVRAM System ID number in Prepare the nodes for upgrade

    Go to Retire node2.

    Did not record the NVRAM System ID number in Prepare the nodes for upgrade

    Complete Step 9 and Step 10 and then go to the next section, Retire node2.

  9. Display the attributes of node 2:

    system node show -instance -node node2

    cluster::> system node show -instance -node node2
                                ...
                     NVRAM System ID: system_ID
                               ...
  10. Record the NVRAM System ID to use in the section Install and boot node4.
