This documents the basic procedure for upgrading zCenter if high availability (HA) is not configured. If you need to update a zCenter with High Availability (HA) configured, use the "zCenter Upgrade Procedure with High Availabilty (HA) Configuration via zCLI" document.

Requirements

• Access to the zCenter admin portal as Service Admin 

• zCLI Access

• The upgrade package must be hosted and accessible by the zCenter server (https/sftp/scp)

Procedure

1. Login to zCenter portal

   • Verify Service domain name and version (verify version is lower than upgrade version

     • Bring up the Service Overview by navigating to Advanced Management, then click on the logo in the upper left

   • Notify any users who are currently logged in. You may view the logged-in users through the following pages:

     • Advanced Management --> Project Management --> Current CoIP User Login Sessions

2. Login to zCLI on zCenter server

   • SSH to the zCenter with username ztu (requires password)

   • zCLI@{server name}> enable (requires zcli enable password)

   • zCLI@{server name}# service

   • zCLI@{server name}(service)# controller

   • zCLI@{server name}(service-zgw)# show swversion (verify is older version than upgrade version)

     Network Switch Version: {ZNS switch version}
     Web Portal Version: {ZGW current version}
     zCLI Version: {zCLI current version}

   • zCLI@{server name}(service-zgw)# service status

     keepalived is inactive and dead...
     Checking MySQL... Running
     Checking ZGW service... Running
     Checking zns ... Running

3. Upgrade Zentera software

   • zCLI@{server name}(service-zgw)# upgrade download <ZGW upgrade download location> (see notes.1 below if zCenter cannot directly access Zentera provided public URL.)

   • zCLI@{server name}(service-zgw)# upgrade download <zCLI upgrade download location> (if upgrading)

   • zCLI@{server name}(service-zgw)# upgrade list (verify upgrade version and copy file name)

   • zCLI@{server name}(service-zgw)# upgrade deploy gw <ZGW upgrade file name>

     Check response for errors
     And follow instructions on the screen to re-enter the enable mode

   • Check the upgrade log for any errors.

   • zCLI@{server name}(service-zgw)# upgrade deploy cli <zCLI upgrade file name> (if upgrading)

     Check response for errors

   • zCLI@{server name}(service-zgw)# show swversion (verify upgrade version as expected)

     Switch Version: {switch version}
     Web Portal Version: {ZGW upgrade version}
     zCLI Version: {zCLI upgrade version}

   • zCLI@{server name}(service-zgw)# service status

     keepalived is inactive and dead...
     Checking MySQL... Running
     Checking ZGW service... Running
     Checking zns ... Running

4. Verify service status of server

   • zCLI@{server name}(service-zgw)# service status

     keepalived is inactive and dead...
     Checking MySQL... Running
     Checking ZGW service... Running
     Checking zns ... Running

5. Repeat step 2 to verify all services are up and operational with upgraded version

6. Repeat step 1 to verify zCenter is up and operational with upgraded version

Notes

1. Options for retrieving the downloadable upgrade package

   • This step may be customized to 2 sub-steps if zCenter cannot directly reach Zentera provided public URL where zCenter is hosted in a LAN that does not allow traffic to go to Internet:

     1. Download the package to a local drive and transport it to a place that allows https or scp from where zCenter is located.

     2. If the place is a web server with https capability, place the package to the server with an accessible URL like https://<web-ip>/path/package by zCenter, then issue the command below:
        

        zCLI@{server name}(service-zgw)# upgrade download https://<web-ip>/path/package

        If the place is a storage server with scp capability, place the package to the server where a user can access after login like /homepath/package, then issue the command below:

        zCLI@{server name}(service-zgw)# upgrade download user@<server-ip>:/homepath/package
        Password: ********
