      cp /home/omuser/crl.pem /opt/product/snas/etc/cert/alarm/crl.pem

    5. Run ssh omuser@10.99.1.2 and enter the omuser user password to go to the node.
    6. Run su - root and enter the password of root to switch to the user root.
    7. Run following commands to replace the certificate of non management node.

      cp /home/omuser/cacert.pem /opt/product/snas/etc/cert/alarm/cacert.pem

      cp /home/omuser/crl.pem /opt/product/snas/etc/cert/alarm/crl.pem

  3. Optional: Replace the communication certificate between admin user password retrieve mail server and OceanStor 9000.
    1. Use Filezilla to upload the certificate to the /home/omuser directory of the node where the management IP address resides.

    2. Start PUTTY and enter the management IP address to log in as account omuser to the cluster. The default password is Omuser@storage. run following commands.

      scp cacert.pem omuser@10.99.1.2:/home/omuser/

      scp crl.pem omuser@10.99.1.2:/home/omuser

    3. Run su - root and enter the password of root to switch to the user root.
    4. Run following commands to replace the certificate of management node.

      cp /home/omuser/cacert.pem /opt/product/snas/etc/cert/password/cacert.pem

      cp /home/omuser/crl.pem /opt/product/snas/etc/cert/password/crl.pem

    5. Run ssh omuser@10.99.1.2 and enter the omuser user password to go to the node.
    6. Run su - root and enter the password of root to switch to the user root.
    7. Run following commands to replace the certificate of non management node.

      cp /home/omuser/cacert.pem /opt/product/snas/etc/cert/password/cacert.pem
