To upgrade a geo-redundant Release 25.11 or earlier auxiliary database
Description
Note: This procedure is performed as part of the NSP or NFM-P upgrade pathway.
The following procedure describes how to upgrade a geo-redundant NSP auxiliary database from Release 25.11 or later.
The auxiliary database upgrade requires an OS upgrade from RHEL 8 to RHEL 9. The procedure outlines steps to migrate from RHEL 8 to RHEL 9, which requires reinstallation of the RHEL 9 OS. In-place upgrade from RHEL 8 to RHEL 9 is also supported.
Note: A geo-redundant auxiliary database is composed of two clusters, one primary (active mode) and the other in standby mode at the time the upgrade begins. In order to reduce the overall system downtime during upgrade, the auxiliary database cluster that is in standby mode at the beginning of the upgrade process is upgraded first while the second cluster continues to operate. When the first cluster is upgraded it is activated (becomes the primary cluster) and the second cluster is then upgraded.
Note: You require the following user privileges on each auxiliary database station:
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
Steps
Obtain software | |||
1 |
Download the following installation files: where R.r.p is the NSP release identifier, in the form MAJOR.minor.patch v is a version number | ||
2 |
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 | |||
3 |
Before upgrading the auxiliary database, 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 the My First NSP API Client 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: { "auxdb-agent": { "name": "nspos-auxdb-agent", "application-mode": "ACTIVE", "copy-cluster": { "source-cluster": "cluster_2", "target-cluster": "cluster_1", "time-started": "timestamp", "status": "SUCCESS" } } } | ||
Back up database | |||
4 |
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. Before upgrading the first auxiliary database cluster (typically 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. | ||
Enable maintenance mode on auxiliary database agent | |||
5 |
Before upgrading the auxiliary database, perform the following steps.
| ||
Stop database proxies | |||
6 |
Perform the following to stop the auxiliary database proxy services.
| ||
Stop auxiliary database | |||
7 |
Log in as the root user on a station in the auxiliary database cluster that you are upgrading. | ||
8 |
Open a console window. | ||
9 |
Enter the following: # cd /opt/nsp/nfmp/auxdb/install/bin ↵ | ||
10 |
Enter the following to block external access to the auxiliary database ports: # ./auxdbAdmin.sh shieldsUp ↵ | ||
11 |
Enter the following to stop the auxiliary database: # ./auxdbAdmin.sh stop ↵ The following prompt is displayed: Please enter auxiliary database dba password [if you are doing initial setup for auxiliary database, press enter]: | ||
12 |
Enter the dba password. Information like the following is displayed: Database samdb stopped successfully Database status Node | Host | State | Version | DB ------------+---------------+-------+---------+------- node_1 | internal_IP_1 | STATE | version | db_name node_2 | internal_IP_2 | STATE | version | db_name ... node_n | internal_IP_n | STATE | version | db_name Output captured in log_file Note: If the inital stop does not succeed, force_stop is attempted automatically until the auxiliary database is stopped. If the database does not stop, do not proceed to the next step and contact Nokia support for further assistance. | ||
Prepare each station for upgrade | |||
13 |
Perform the following steps on each existing auxiliary database station in the cluster. Log in as the root user on the station. | ||
