  1. Change the project to ibm-spectrum-fusion-ns.
    oc project ibm-spectrum-fusion-ns
  2. Run the following example command to fetch the switch up:
    oc get switch hspeed2-rackc -o yaml | grep switchIpadress
    Example output: 
    switchIpadress: fd8c:215d:178e:c0de:1e34:daff:feb2:eb00
  3. Run the following example command to get the switch credentials: 
    oc get secret | grep hspeed2-rackc
    hspeed2-rackc-licensesecret                                       Opaque                                1      31d
hspeed2-rackc-secret                     
    oc get secret hspeed2-rackc-secret -o yaml | grep SVNGVVNFUg==
  isfmgmtUserName: SVNGVVNFUg==
    oc get secret hspeed2-rackc-secret -o yaml | grep NEdTbGRwckxkNw==
  isfmgmtUserPasswrd: NEdTbGRwckxkNw==
  4. Decode the username and password that is obtained from the previous commands.
    echo <username/password> | base64 --decode
  5. Log in to the switch by using the following steps. Use username and password that you got from the previous step 3 after decoding.
    oc get nodes

  6. Log in to the other switch by using steps 1 to 3 and check whether the uplink interfaces are up.
    net show inter | egrep "swp31|swp32"
    UP     swp31          40G   9216   BondMember    e3f3h14-3132a (Ethernet1/5)        Master: rackclink(UP)
       rackclink                                                                    Bond Members: swp31(UP)
  7. Use the following command to set the interface up.
    nv set interface swp32 link state up 
nv config apply -y 

    applied [rev_id: 83]
    nv config save 
    saved [rev_id: applied]
  8. Check whether the interface is up after step 4. If it does not come up, run the following command: 
    sudo ifreload -a
    Check again using the step 4.
  9. If it does not come up, check the physical connection between the uplink port to your switch or else contact IBM Support.
