About

The SevOne NMS software is loaded on your appliance. If you provide the IP address of the appliance to your SevOne Sales Engineer this has been entered for you.

This document describes what you must do to get the appliance up and running from the moment you open the box until you are ready to log on to the application. Please refer to SevOne NMS Implementation Guide for how to log on, how to build a SevOne cluster, and how to begin your SevOne implementation.

Terminology usage...

In this guide if there is,

  • [any reference to master] OR

  • [[if a CLI command contains master] AND/OR

  • [its output contains master]],
    it means leader.

And, if there is any reference to slave, it means follower.

Multi-Peer and Hot Standby Appliance Implementations

The Cluster Manager provides an Integration tab to enable you to build your cluster and to add new appliances as peers into an existing cluster. Please refer to SevOne NMS Implementation Guide for details.

When your new appliance is a Hot Standby Appliance, perform the steps in chapter 2 to rack up and define the Configuration Menu settings then contact SevOne Support to ensure that the Hot Standby Appliance is appropriately implemented.

Hardware Requirements

Recommendation

In a cluster that contains mixed sized appliances, the largest hardware capacity appliance should be the Cluster Leader. There is RAM overhead exerted on the Cluster Leader based on its additional responsibilities. Due to this, SevOne strongly advises you to implement this recommendation.

The average disk Input / Output Operations Per Second (IOPS) requirement for all appliance types is 19,000KBs.

The minimum NIC speed is 1Gbps or higher.

RAID controller requires legacy boot (non-UEFI) with 512 byte block size in RAID6 (recommended).

IMPORTANT

SevOne NMS 6.8.0 and above allows user to bring their own hardware for physical deployments. The minimum resource requirements in the table below must be met based on the appliance model being deployed. The hardware must be compatible with Red Hat Enterprise Linux (RHEL) 8.

For details on advanced Network Configurations such as configuring Virtual IP (CentOS) or peer communication over NAT, please refer to SevOne NMS Advanced Network Configuration Guide for details.

OS-level User Names and Passwords

You will need to change the default passwords for the admin, root, and support user accounts. This is important for security reasons.

Failure to change the default passwords presents a significant security risk. This publication includes default passwords and this document has probably been made available to the public.

Change Admin Password

The admin user is not used by any SevOne utilities. It exists for administrators/customers. This password should be changed on all peers. Perform the following steps to change the password for admin.

  1. SSH into your SevOne NMS appliance and log in as admin.

  2. At the Password prompt, enter adminuser.

    images/download/attachments/174598664/commandLine_adminAcct-version-1-modificationdate-1706554418601-api-v2.png

  3. You will be prompted and required to change the admin user password. Enter a new password when prompted.

  4. Exit the session when you are done.

Change Root Password

Change Root Password Before Peering

You must change the root password for new appliances when you SSH into the system. You will be prompted for the default password and will be required to change the password. This must be completed before incorporating the new peer into a cluster. Security concerns prevent incorporation of peers that use the default password.

SevOne NMS uses the root account for everything. This password should be changed on all peers. Perform the following steps to change the password for root.

  1. SSH into your SevOne NMS appliance and log in as root.

  2. At the Password prompt, enter dRum&5853.

    images/download/attachments/174598664/commandLine_rootAcct_forceChange-version-1-modificationdate-1706554418933-api-v2.png

  3. You will be prompted and required to change the root user password. Enter a new password when prompted.

  4. Exit the session when you are done.

Change Support Password

The support user is used by configshell. Configshell does not store the password for this account anywhere. You will need the password you specify here when logging in to configshell. This password should be changed on all peers. Perform the following steps to change the password for support.

  1. SSH into your SevOne NMS appliance and log in as support.

  2. At the Password prompt, enter supportuser.

    images/download/attachments/174598664/commandLine_supportAcct-version-1-modificationdate-1706554418931-api-v2.png

  3. You will be prompted and required to change the support user password. Enter a new password when prompted.

  4. Exit the session when you are done.


Change IP Address, Configure Network Bonding

For details on how to change the IP address on a SevOne appliance or how to configure networking bonding, please refer to the respective sections in SevOne NMS Advanced Network Configuration Guide.

Enable Firewall

Firewall can be enabled / disabled at cluster-level or on a selected peer.

at Cluster-level

By default, firewall service is disabled for the cluster. Please refer to SevOne NMS System Administration Guide > section Cluster Manager > Cluster Settings tab > Firewall subtab for details.

at Peer-level

By default, Override Cluster Settings is disabled. To override cluster-level firewall settings with firewall settings at the selected peer-level, enable Override Cluster Settings. Once Override Cluster Settings field is enabled, field Enable Firewall becomes available. By default, Enable Firewall is disabled. Please refer to SevOne NMS System Administration Guide > section Cluster Manager > select a peer > click Peer Settings tab > Firewall subtab for details.

Shut Down and Reboot SevOne NMS

SevOne NMS can run for extended periods of time. Occasionally it is necessary to shutdown or reboot an appliance. SevOne NMS stores data in cache and writes to the disk on a regular basis. The following shell commands back up the memory ring tables to the database on the disk to ensure that you do not lose data.

  • To shutdown SevOne NMS.

    $ SevOne-shutdown shutdown

  • To reboot SevOne NMS.

    $ SevOne-shutdown reboot
