Recovery Kit for JP1/AJS Administration Guide

Overview

The Recovery Kit for JP1/AJS provides fault-tolerant protection for the integrated system management software “JP1” developed by Hitachi, Ltd. If a failure occurs in the protected JP1 software, LifeKeeper first attempts recovery on its primary server. If the recovery fails, it executes a failover to the standby server. The following resources used by JP1 software are protected by the appropriate Recovery Kit (RK).

The JP1 products that the Recovery Kit for JP1/AJS can protect are as follows:

• JP1/Base
• JP1/Automatic Job Management System 3 Manager（JP1/AJS3 – Manager）
• JP1/Automatic Job Management System 3 Agent（JP1/AJS3 – Agent）

The resource hierarchy for protecting JP1/AJS3 – Manager is as follows (Subresources under File System Resource have been omitted.):

JP1/AJS3-Manager Resource
    + JP1/Base Resource
        + IP Address Resource
        + File System Resource

The resource hierarchy for protecting JP1/AJS3 – Agent is as follows (Subresources under File System Resource have been omitted.):

JP1/AJS3-Agent Resource
    + JP1/Base Resource
        + IP Address Resource
        + File System Resource

This document describes the operation of the Recovery Kit for JP1/AJS. For general LifeKeeper terminology and usage, refer to LifeKeeper for Linux Technical Documentation. For information about JP1, refer to the JP1 manual .

Prerequisites

• You must have an IP Address resource, a File System Resource hierarchy (including any child resources required by the File System Resource). Create these resources before creating the JP1/AJS resource. However, for LifeKeeper Single Server Protection, they may not be required depending on the configuration.
• Configurations using Network Attached Storage (NAS) Resources as the base of the File System Resource hierarchy are not supported.
• When using DataKeeper or DRBD as the base of the File System Resource hierarchy, configure it for synchronous replication.
• Do not install JP1/Base within a File System protected by a File System Resource.
• The logical hostname specified during JP1 setup must be 32 bytes or less, as this is required when configuring JP1 in a cluster.
