To upgrade a redundant Release 22.6 or earlier NFM-P system

Description

The following steps describe how to upgrade a collocated or distributed Release 22.6 or earlier main database and main server in a redundant deployment. The steps include links to procedures for installing and upgrading optional NFM-P components.

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

Note: You require the following user privileges:

on each server station in the system — root, nsp
on each main database station — root

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$ —nsp user

Steps

Check pre-upgrade disk space

As part of the trial upgrade on a lab system in advance of a live upgrade, you must ensure that the available disk capacity on each NFM-P component remains within tolerance.

Note: If the disk usage on an NFM-P partition approaches or exceeds 80% after the trial upgrade, you may need to add disk capacity before you attempt the upgrade on a live system.

Perform the following steps on each of the following stations:

main server
auxiliary server
main database
NSP auxiliary database

Log in to the station as the root user.
Open a console window.
Enter the following:

# df -kh ↵

The usage information for each partition is displayed.
Record the information for each NFM-P partition; see the tables in Chapter 2, NSP disk setup and partitioning for the partition names and required capacities.

Stop and disable standby main server [Main2]

Open a GUI client to monitor the network during the upgrade.

Stop the standby main server.

Log in to the standby main server station as the nsp user.
Open a console window.
Enter the following:

bash$ cd /opt/nsp/nfmp/server/nms/bin ↵
Enter the following:

bash$ ./nmsserver.bash stop ↵
Enter the following:

bash$ ./nmsserver.bash appserver_status ↵

The server status is displayed; the server is fully stopped if the status is the following:

Application Server is stopped

If the server is not fully stopped, wait five minutes and then repeat this step. Do not perform the next step until the server is fully stopped.
Enter the following to switch to the root user:

bash$ su ↵

Disable the automatic main server startup so that the main server does not start in the event of a power disruption during the upgrade.

Enter the following:

# systemctl disable nspos-nspd.service ↵
Enter the following:

# systemctl disable nfmp-main-config.service ↵
Enter the following:

# systemctl disable nfmp-main.service ↵

Stop auxiliary servers [Aux2]

If the NFM-P system includes auxiliary servers, stop each appropriate auxiliary server [Aux2].

Log in to the auxiliary server station as the nsp user.
Open a console window.
Enter the following:

bash$ /opt/nsp/nfmp/auxserver/nms/bin/auxnmsserver.bash auxstop ↵

The auxiliary server stops.

Disable database redundancy

Disable the main database failover and switchover functions.

Log in to the primary main server station [Main1] as the nsp user.
Open a console window.
Enter the following to navigate to the main server configuration directory:

bash$ cd /opt/nsp/nfmp/server/nms/config ↵
Make a backup copy of the nms-server.xml file.
Open the nms-server.xml file with a plain-text editor, for example, vi.
Locate the section that begins with the following tag:

<db
Locate the following line in the section:

host="address"
Ensure that the address value in the line is the IP address of main database [DB1].
Locate the following line in the section:

database="instance_name"
Ensure that the instance_name value is the instance name of main database [DB1].
Edit the following line in the section that reads:

redundancyEnabled="true"

to read:

redundancyEnabled="false"
Save and close the nms-server.xml file.
Enter the following:

bash$ /opt/nsp/nfmp/server/nms/bin/nmsserver.bash read_config ↵

The main server puts the change into effect, and database redundancy is disabled.

Upgrade standby main database [DB2]

Note: After the upgrade, the station is the new primary main database station.

Open a console window.

Stop and disable the Oracle proxy and main database services.

Enter the following to stop the Oracle proxy:

# systemctl stop nfmp-oracle-proxy.service ↵
Enter the following to disable the automatic Oracle proxy startup:

# systemctl disable nfmp-oracle-proxy.service ↵
Enter the following to stop the main database:

# systemctl stop nfmp-main-db.service ↵
Enter the following to disable the automatic database startup:

# systemctl disable nfmp-main-db.service ↵

If analytics aggregations are enabled, perform the following steps to disable all aggregation rules.

Note: Disabling analytics aggregation during a redundant system upgrade prevents the duplication of aggregation data in the NFM-P database, but does not cause the loss of any aggregation data.

Upon startup, if a primary main server detects that the most recent aggregation data is not current, the server performs the interim aggregations. If aggregation is enabled during a redundant upgrade, the original primary main server creates aggregations while the standby main server is upgraded. In such a case, after the standby main server starts as the new primary main server, the server may perform aggregations that are duplicates of the aggregations performed by the original primary main server.

The required aggregation rules are automatically enabled on the new primary main server, so the server performs the interim aggregations upon startup. If aggregation is disabled at the start of a redundant upgrade, no aggregation duplication occurs.

Open an NFM-P GUI client.
Choose Tools→Analytics→Aggregation Manager from the NFM-P main menu. The Aggregation Manager form opens.
Click Search. The aggregation rules are listed.
Click on the Enable Aggregation column to sort the rules so that the rules that have aggregation enabled are at the top of the list.
Select all rules that have a check mark in the Enable Aggregation column.
Click Properties. The Aggregation Rule (multiple instances) [Edit] form opens.
Deselect Enable Aggregation.
Click OK. The Aggregation Rule (multiple instances) [Edit] form closes.
Click OK to save your changes and close the Aggregation Manager form.
Close the NFM-P GUI client.

Perform the following steps.

Open the /etc/fstab file using a plain-text editor such as vi.
Locate the tmpfs file system entry.
Remove the noexec option so that the entry reads as follows:

tmpfs /dev/shm tmpfs nodev 0 0
Save and close the /etc/fstab file.
Enter the following to remount the /dev/shm partition:

# mount -o remount /dev/shm ↵

If you are re-using the standby main database [DB2] station, recommission the station according to the platform specifications in this guide and in the NSP Planning Guide.

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

Note: After the upgrade, the station is the new primary main database station.

Perform one of the following.

If the main server and database are collocated on one station, perform the following steps.
1. Enter the following:

Enable Windows Active Directory access

If you intend to use Windows Active Directory, or AD, for single sign-on client access, you must configure LDAP remote authentication for AD; otherwise, go to Step 86.

Open the following file as a reference for use in subsequent steps:

/opt/nsp/os/install/examples/config.yml

Note: Consider the following.

The NFM-P does not assign a default user group to users of a remote authentication source that you define for Windows AD; the authentication source must provide the user group attributes.
Windows AD supports the following LDAP server types for remote authentication:

AD—The user group of an AD user is derived from the group_base_dn attribute in the server configuration; group search filters are not supported.

AUTHENTICATED—The server configuration must include bind credentials; group search filters are supported. After NFM-P initialization, you add the AD server bind credentials to the NSP password vault using the NSP Session Manager RESTCONF API.

Locate the section that begins with the following lines:

# ldap:

# enabled: true

# servers:

# - type: AUTHENTICATED/AD/ANONYMOUS

# url: ldaps://ldap.example.com:636

# security: SSL/STARTTLS/NONE

Open the following file using a plain-text editor such as vi:

/opt/nsp/os/install/config.json

Locate the section that begins with the following line:

"sso": {

The section has one subsection for each type of SSO access.

Note: You can enable multiple remote authentication methods such as LDAP and RADIUS in the config.json file, or by using the NFM-P GUI. Using the GUI also allows you to specify the order in which the methods are tried during login attempts; however, no ordering is applied to multiple methods enabled in the config.json file.

In the sso section, create an ldap subsection as shown below using the parameter names from the ldap section of config.yml and the required values for your configuration.

The following example shows the LDAP configuration for two AD servers:

    "ldap": {

      "enabled": true,

      "servers": [

          "type": "auth_type",

          "url": "ldaps://server1:port",

          "server1_parameter_1": "value",

          "server1_parameter_2": "value",

          "server1_parameter_n": "value",

},

          "type": "auth_type",

          "url": "ldaps://server2:port",

          "server2_parameter_1": "value",

          "server2_parameter_2": "value",

          "server2_parameter_n": "value",

},

}]

where auth_type is AD or AUTHENTICATED

Save and close the files.

Enter the following:

# samconfig -m main ↵

The following is displayed:

Start processing command line inputs...

<main>

Enter the following:

<main> apply ↵

The AD LDAP configuration is applied.

Enter the following:

<main> exit ↵

The samconfig utility closes.

Integrate NFM-P and NSP cluster

100

If you are upgrading an NFM-P system that is not currently integrated with an NSP cluster, perform procedure To add an independent NFM-P to an existing NSP deployment.

Note: Performing the procedure also starts the main server.

Start new primary main server [Main2]

101

CAUTION

Service Disruption

The new primary database [DB2] must be upgraded and running before you start the new primary main server [Main2], or the main server initialization may fail.

If you perform the new primary main server and database upgrades concurrently, do not perform this step until the database upgrade is complete.

CAUTION

Service Disruption

An NFM-P system upgrade is not complete until each main server performs crucial post-upgrade tasks during initialization.

Before you attempt an operation that requires a server shutdown, you must ensure that each main server is completely initialized, or the operation fails.

Start the new primary main server [Main2].

Note: You cannot start a main server unless the main server configuration includes a current and valid license. You can use samconfig to specify the license file, or import a license, as described in the NSP System Administrator Guide.

Log in as the nsp user on the new primary main server station [Main2].
Enter the following:

bash$ cd /opt/nsp/nfmp/server/nms/bin ↵
Enter the following:

bash$ ./nmsserver.bash start ↵
Enter the following:

bash$ ./nmsserver.bash appserver_status ↵

The server status is displayed; the server is fully initialized if the status is the following:

Application Server process is running. See nms_status for more detail.

If the server is not fully initialized, wait five minutes and then repeat this step. Do not perform the next step until the server is fully initialized.

Note: This marks the end of the network management outage.

102

If you have enabled Windows Active Directory access using the AUTHENTICATED type of LDAP server, use the NSP Session Manager RESTCONF API to add the LDAP server bind credentials; see the Network Developer Portal for information.

103

Specify the memory requirement for GUI clients based on the type of network that the NFM-P is to manage.

Enter the following:

bash$ ./nmsdeploytool.bash clientmem -option ↵

where option is one of the following:
- m—medium, for management of limited-scale network
- l—large, for a network of 15 000 or more NEs
Record the setting, which is not preserved through an upgrade, for future use.
Enter the following to commit the configuration change:

bash$ ./nmsdeploytool.bash deploy ↵

Start auxiliary servers [Aux2]

104

If the NFM-P system includes auxiliary servers, start each appropriate auxiliary server [Aux2].

Log in to the auxiliary server station as the nsp user.
Open a console window.
Enter the following:

bash$ cd /opt/nsp/nfmp/auxserver/nms/bin ↵
Enter the following:

bash$ ./auxnmsserver.bash auxstart ↵

The auxiliary server starts.

Activate upgraded former standby auxiliary database cluster

105

If the system includes an auxiliary database, issue the following RESTCONF API call to activate the former standby auxiliary database cluster, after which the cluster assumes the primary role:

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

POST https://address/restconf/data/auxdb:/clusters/cluster=cluster_N/activate

where

address is the advertised address of the primary NSP cluster

N is the auxiliary database cluster number

The following is the request body:

{

"auxdb:input" : {

"force": true

}

The cluster is activated.

Perform NSP analytics server migration to NSP cluster

106

If the system includes one or more NSP analytics servers, move the analytics-server functions to the NSP cluster, as described in NSP analytics server migration from Release 22.6 or earlier.

Enable GUI client

107

You require an NFM-P GUI client to complete the procedure; see the following for information:

Note: A client delegate server installation typically takes more time than the other options. A single-user client or client delegate server upgrade is recommended if your maintenance period is limited.

Test upgraded system using GUI client

108

When the new primary main server [Main2] is started, use a newly installed or upgraded GUI client to perform sanity testing of the new primary main server and database.

Note: To back out of the upgrade and return the original primary main server [Main1] and database [DB1] to service, you can do so by stopping the new primary main server [Main2] and database [DB2] and restarting the original primary main server [Main1] and database [DB1].

Uninstall original primary database [DB1]

109

Enter the following to uninstall the original primary main database:

# yum remove nsp-nfmp-main-db nsp-nfmp-oracle ↵
