To upgrade a geo-redundant Release 22.9 or later auxiliary database

Description

The following procedure describes how to upgrade a geo-redundant NSP auxiliary database from Release 22.9 or later.

Note: You require the following user privileges on each auxiliary database station:

  • root

  • samauxdb

Note: Ensure that you record the information that you specify, for example, directory names, passwords, and IP addresses.

Note: The following RHEL CLI prompts in command lines denote the active user, and are not to be included in typed commands

  • # —root user

  • bash$ —samauxdb user

Steps
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>


Back up database
 
CAUTION 

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 and disable standby database proxies
 

If you are upgrading the standby auxiliary database cluster, perform one of the following to stop the auxiliary database services:

  1. If you are upgrading from Release 23.11, enter the following:

    systemctl disable nspos-auxdbproxy.service ↵

  2. If you are upgrading from Release 23.8 or earlier, enter the following sequence of commands:

    systemctl disable nfmp-auxdbproxy.service ↵


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 standby auxiliary database services
 

If you are upgrading the standby auxiliary database cluster, perform one of the following to disable the database services:

  1. If you are upgrading from Release 23.11, enter the following sequence of commands

    systemctl disable nspos-auxdb.service

    systemctl disable vertica_agent.service

    systemctl disable verticad.service

  2. If you are upgrading from Release 23.8 or earlier, enter the following sequence of commands:
