Installation Overview

Installation Overview

This chapter describes the terms and restrictions involved when the eSight Veritas hot-standby high availability (HA) system is installed on the SUSE Linux operating system.

Terms

Terms in this document are described as follows:

  • Server: A server can refer to the hardware and/or software. In the browser/server structure, a server refers to the server program. The term refers to hardware when it is used in reference to a computer where a server program runs.
  • Workstation and host: A workstation functions the same as a host. Generally, a workstation or host refers to the computer where services run in the SUSE Linux operating system.
  • Primary (secondary) server: The primary (secondary) server refers to the physical primary (secondary) server in an HA system. Whether a server is a primary server or a secondary server is specified during installation, and the server role remains unchanged when an active/standby switchover occurs. In most time, the primary server is in the active state while the secondary server is in the standby state to serve as a backup of the primary server.
  • Active (standby) server: An active (standby) server refers to the server in the active (standby) state in an HA system. The server in the standby state serves as a backup of the server in the active state.
  • Active (standby) state: The active (standby) state refers to the working (backup) state in an HA system. For example, if all relevant applications on a server run normally, the server is in the active state.

Restrictions

The following restrictions must be followed when the eSight HA system is installed.

Table 1-1 Installation restrictions

Item

Restriction

Server

The active and standby servers must use a secure networking scheme, for example, virtual private network (VPN) with encrypted links, to ensure data transmission security.

To prevent program conflict, it is recommended that other unnecessary software not be installed on the eSight server.

Only one eSight can be installed on a server.

The language of eSight on the active node must be the same as that on the standby node.

During eSight installation or startup, only one user can perform operations on the server. If multiple users perform operations on the server simultaneously, the installation or startup will fail.

Operating system

The eSight software can be installed on the operating system supporting simplified Chinese or English.

Do not modify the system configurations (such as environment variables and host names) except for the operations described in this document. Otherwise, eSight may become abnormal.

If eSight is deployed on the SUSE Linux operating system, antivirus software cannot be installed.

  • A local HA system (SUSE Linux) consists of the active server and the standby server. Each server is composed of one workstation.
  • In a four-NIC solution, heartbeat lines are reused as replication lines and bond needs to be configured; system lines are reused as application lines and bond and floating IP addresses need to be configured.
  • After restart, the two-node cluster system needs to be manually restarted by the administrator because it cannot automatically restart.
  • If eSight is deployed on the SUSE Linux operating system, antivirus software cannot be installed.
