Obtain software

Download the following installation files:

• nspos-auxdb-R.r.p-rel.v.rpm

• VerticaSw_PreInstall.sh

• nspos-jre-R.r.p-rel.v.rpm

• vertica-R.r.p-rel.tar

where

R.r.p is the NSP release identifier, in the form MAJOR.minor.patch

v is a version number

For each auxiliary database cluster, transfer the downloaded files to a station that is reachable by each station in the cluster.

Verify auxiliary database synchronization

If you are upgrading the standby auxiliary database cluster, you must verify the success of the most recent copy-cluster operation, which synchronizes the database data between the clusters.

Note: You must not proceed to the next step until the operation is complete and successful.

Issue the following RESTCONF API call periodically to check the copy-cluster status:

Note: In order to issue a RESTCONF API call, you require a token; see this tutorial on the Network Developer Portal for information.

GET https://address/RESTCONF/data/auxdb:/auxdb-agent

where address is the advertised address of the primary NSP cluster

The call returns a status of SUCCESS, as shown below, for a successfully completed copy-cluster operation:

<HashMap>

      <auxdb-agent>

         <name>nspos-auxdb-agent</name>

         <application-mode>ACTIVE</application-mode>

         <copy-cluster>

            <source-cluster>cluster_M</source-cluster>

            <target-cluster>cluster_N</target-cluster>

            <time-started>timestamp</time-started>

            <status>SUCCESS</status>

         </copy-cluster>

      </auxdb-agent>

</HashMap>

Stop and disable auxiliary database proxies

If you are upgrading the standby auxiliary database cluster, stop and disable the database proxy on each station in each auxiliary database cluster.

1. Enter the following sequence of commands as the root user on each station in the standby auxiliary database cluster:

   systemctl stop nfmp-auxdbproxy.service

   systemctl disable nfmp-auxdbproxy.service

   The proxy stops, and is disabled.

2. Enter the following sequence of commands as the root user on each station in the primary auxiliary database cluster:

   systemctl stop nfmp-auxdbproxy.service

   systemctl disable nfmp-auxdbproxy.service

   The proxy stops, and is disabled.

Enable maintenance mode on auxiliary database agent

If you are upgrading the standby auxiliary database cluster, enable nspos-auxdb-agent maintenance mode.

1. Log in as the root user on the NSP cluster host in the primary data center.

2. Enter the following to set the nspos-auxdb-agent mode to maintenance:

   # kubectl patch configmap/nspos-auxdb-agent-overrides -n namespace --type=merge -p '{"data":{"nspos-auxdb-agent-overrides.json":"{\"auxDbAgent\":{\"config\":{\"maintenance-mode\":true}}}"}}' ↵

   where namespace is the nspos-auxdb-agent namespace

3. Enter the following to restart the nspos-auxdb-agent pod:

   # kubectl delete -n namespace pod `kubectl describe -n namespace pods | grep -P ^^Name: | grep -oP nspos-auxdb-agent[-a-zA-Z0-9]+` ↵

4. Issue the following RESTCONF API call against the primary NSP cluster to verify that the agent is in maintenance mode:

   NOTE: In order to issue a RESTCONF API call, you require a token; see this tutorial on the Network Developer Portal for information.

   GET https://address/RESTCONF/data/auxdb:/auxdb-agent

   where address is the advertised address of the primary NSP cluster

   The call returns information like the following:

   {

       "auxdb-agent": {

           "name": "nspos-auxdb-agent",

           "application-mode": "MAINTENANCE",

           "copy-cluster": {

               "source-cluster": "cluster_2",

               "target-cluster": "cluster_1",

               "time-started": "timestamp",

               "status": "SUCCESS"

           }

       }

   }

   The agent is in maintenance mode if the application-mode is MAINTENANCE, as shown in the example.

5. Log in as the root user on the NSP cluster host in the standby data center.

6. Enter the following to set the nspos-auxdb-agent mode to maintenance:

   # kubectl patch configmap/nspos-auxdb-agent-overrides -n namespace --type=merge -p '{"data":{"nspos-auxdb-agent-overrides.json":"{\"auxDbAgent\":{\"config\":{\"maintenance-mode\":true}}}"}}' ↵

Stop and disable auxiliary database proxies

If you are upgrading the standby auxiliary database cluster, stop and disable the database proxy on each station in each auxiliary database cluster.

1. Enter the following sequence of commands as the root user on each station in the standby auxiliary database cluster:

   systemctl stop nfmp-auxdbproxy.service

   systemctl disable nfmp-auxdbproxy.service

   The proxy stops, and is disabled.

2. Enter the following sequence of commands as the root user on each station in the primary auxiliary database cluster:

   systemctl stop nfmp-auxdbproxy.service

   systemctl disable nfmp-auxdbproxy.service

   The proxy stops, and is disabled.

Commission new stations, if required

If you are deploying the auxiliary database on one or more new stations, perform the following steps.

For information about deploying the RHEL OS using an NSP OEM disk image, see NSP disk-image deployment.

Note: The IP addresses on the interfaces of a new auxiliary database station must match the addresses on the station that it replaces.

1. Commission each station according to the platform specifications in this guide and in the NSP Planning Guide.

2. Perform To apply the RHEL 8 swappiness workaround on the station.

Back up database

CAUTION Data Loss

If you specify a backup location on the database data partition, data loss or corruption may occur.

The auxiliary database backup location must be an absolute path on a partition other than the database data partition.

If you are upgrading the standby cluster, back up the auxiliary database as described in the NSP System Administrator Guide for the installed release.

Note: The backup location requires 20% more space than the database data consumes.

Note: If the backup location is remote, a 1 Gb/s link to the location is required; if achievable, a higher-capacity link is recommended.

Stop cluster

Log in as the root user on a station in the auxiliary database cluster that you are upgrading.

Open a console window.

Enter the following:

# cd /opt/nsp/nfmp/auxdb/install/bin ↵

Enter the following to stop the auxiliary database:

# ./auxdbAdmin.sh stop ↵

Enter the following to display the auxiliary database status:

# ./auxdbAdmin.sh status ↵

Go to Step 34.

Prepare individual station for upgrade

Log in as the root user on the station.

Open a console window.

systemctl stop nfmp-auxdb.service

systemctl stop vertica_agent.service

systemctl stop verticad.service

Enter the following sequence of commands to disable the database services:

systemctl disable nfmp-auxdb.service

systemctl disable vertica_agent.service

systemctl disable verticad.service

Transfer the downloaded installation files to an empty directory on the station.

Note: You must ensure that the directory is empty.

Note: In subsequent steps, the directory is called the NSP software directory.

   node_1 = [internal_IP_1]:backup_path

   node_2 = [internal_IP_2]:backup_path

   node_3 = [internal_IP_3]:backup_path

8. Save and close the file.

You must back up the auxiliary database data and configuration information to prepare for the migration to the new OS version.

Note: The operation may take considerable time.

Perform the following steps.
