HP XP P9000 RAID Manager Reference Guide (T1610-96061, January 2014)

1 Overview of commands
This chapter provides an overview of the RAID Manager (RAID Manager) commands.
Summary of commands
RAID Manager is command-line interface (CLI) software that enables you to perform operations
on Hitachi RAID storage systems. RAID Manager can be used from attached hosts and from Storage
Navigator computers.
This document describes and provides the specifications for the RAID Manager commands. There
are four types of RAID Manager commands:
• “Data management commands” (page 14)
• “Configuration setting commands” (page 15)
• “Command tools” (page 18)
• “Subcommands” (page 18)
Data management commands
Data management operations include data replication and data protection operations. Table 1 (page
14) lists the RAID Manager data management commands in alphabetical order and provides a
brief description of each command.
Table 1 Data management commands
DescriptionCommand
Used for both maintenance and troubleshooting on RAID Manager. The horcctl command
allows you to change and display the internal trace control parameters (for example, level,
horcctl
type, buffer size) of the HORC Manager and/or RAID Manager commands. If a new value
is not specified to a parameter, the trace control parameter that is specified currently is
displayed.
Script for stopping HORCM.horcmshutdown
Script that starts HORCM. This script can also set the environment variables for HORCM
as needed (for example, HORCM_CONF, HORCM_LOG, HORCM_LOGS).
horcmstart
Scripted command for executing multiple HORC operation commands combined. It checks
the volume attribute (optionally specified) and decides a takeover action. The horctakeoff
horctakeoff
operation is defined to change from 3DC multi-target to 3DC multi-hop with the state of
running APP, after that the horctakeover command can configure 3DC multi-target on the
remote site without stopping the application. The granularity of either a logical volume or
volume group can be specified with this command.
Scripted command for executing multiple Continuous Access Synchronous takeover
operations. It checks the specified volume's or group's attributes (paircurchk), decides the
horctakeover
takeover function based on the attributes, executes the chosen takeover function, and returns
the result.
Creates a new volume pair from two unpaired volumes.paircreate
Checks the current status of the Continuous Access Synchronous secondary volume(s) by
evaluating the data consistency based on pair status and fence level.
paircurchk
Displays the pair status allowing you to verify completion of pair operations (for example,
paircreate, pairresync). The pairdisplay command is also used to confirm the configuration
of the pair volume connection path (the physical link of paired volumes and servers).
pairdisplay
Waits for completion of pair creation and pair resynchronization and confirms the status
of pair operations
