Overview

This chapter describes the overview of the Universal RAID Utility.

What is Universal RAID Utility?

The Universal RAID Utility enables RAID Systems in a computer to be managed.

The Universal RAID Utility is characterized as follows.

1. Allowing a variety of RAID Systems to be managed

Conventionally, a specific management utility must be used for each RAID System. On the other hand, only the Universal RAID Utility can manage more than one RAID System. For the RAID Systems which the Universal RAID Utility can manage, refer to the documentation on computers and RAID Systems.

2. Operating in either Standard or Advanced Mode

The Universal RAID Utility can operate in two running modes, which are Standard Mode and Advanced Modes. The Standard Mode provides the Universal RAID Utility with standard management functions of RAID Systems. The Advanced Mode provides the Universal RAID Utility with advanced management and maintenance functions of RAID Systems. Using the two running modes appropriately depending on users and jobs allows the usability of the Universal RAID Utility to be improved and malfunctions to be avoided.

3. Configuring RAID Systems easily

Using the Universal RAID Utility, you can configure a RAID System easily without expert knowledge of the RAID System. The Universal RAID Utility provides the "simple Logical Drive create function" allowing a Logical Drive to be created by selecting only two selection items according to the guide of the Universal RAID Utility and the "Easy Configuration" allowing a RAID System to be configured only by defining uses of unused Physical Devices.

4. Supporting general functions required for configurations, operations and maintenances of RAID Systems

The Universal RAID Utility supports general functions for configuring a RAID System (including creating Logical Drive and making Hot Spare), general operation functions (including log recording, Patrol Read and Consistency Check), and general functions required for maintenance (including Rebuild and Locate functions).

5. Troubleshooting RAID Systems

The Universal RAID Utility can detect failures occurred in RAID Systems by using various functions. The RAID Viewer, the GUI of the Universal RAID Utility, indicates the configurations and status of RAID Systems comprehensibly with trees and icons. The raidcmd, the CLI of the Universal RAID Utility, indicates the same information too. In addition, the Universal RAID Utility registers failures occurred in RAID Systems not only to the dedicated log but also the OS log. Further, the Universal RAID Utility can send alerts to the NEC ESMPRO Manager normally attached to NEC Express series systems.

Structure of Universal RAID Utility

The Universal RAID Utility consists of the following modules:

 raidsrv service

The raidsrv service always operates in the computer to manage RAID Systems. Receiving a processing request from the RAID Viewer or raidcmd, the raidsrv service provides proper information on a RAID System or performs an appropriate operation for the RAID System. In addition, the raidsrv service manages events occurred in RAID Systems, notifies the RAID Viewer of the events and/or registers them to several logs.

 RAID Viewer

The RAID Viewer is the Windows application managing and monitoring the RAID system by GUI. The RAID Viewer displays the configuration and status of a RAID System graphically or provides configuration and operation for a RAID System.

 Log Viewer

The Log Viewer is the Windows application viewing the event of RAID system. The Log Viewer allows you to see the RAID Log in which events occurred in RAID Systems are registered.

 raidcmd

The raidcmd is the application managing and monitoring the RAID system by CLI. The raidcmd is the command that indicates the configuration and status of a RAID System or operates on a console providing configurations and operations.

1. Addition of hardware for management

 "Promise RAID Controller" is added to the RAID Controller for management

 SSD(Solid State Drive) is supported

HDD and SSD can be distinguished by the item of the device type in the property of a Physical Device. See "Referring to Property of Physical Device". HDD and SSD cannot exist together in the same Logical Drive. Be careful when creates a Logical Drive or create the Hot Spare.

 Physical Devices other than HDD(SSD is included) are managed

The tape device, the CD drive, and the DVD drive connected with the RAID controller can be referred to in the tree view and property. However, the state monitoring functions of a physical device other than HDD (SSD is included) are not supported.

2. Configuration

 The condition that a logical drive can be deleted is changed

You are not able to delete a Logical Drive with boot partition until Ver 1.4. The condition of the Logical Drive that was able to be deleted was changed in Ver 2.0. For detail, see "Deleting Logical Drive".

3. Operation

 The initialization execution condition of a logical drive is changed

You are not able to initialize a Logical Drive with boot partition until Ver1.4. The condition of the Logical Drive that was able to be initialized was changed in Ver2.0. For detail, see "Initializing Logical Drive".

 Timing in which the Patrol Read is executed is changed

The Patrol Read was executed always continuously until Ver1.4. The timing in which the Patrol Read is executed is changed in Ver2.0. For detail, see "Providing Patrol Read for Physical Devices".

 The way of turn off the lamp for checking location of Physical Device is changed

To turn off the lamp for checking location of Physical Device, always use the RAID Viewer or raidcmd until Ver1.40. When the fixed time had passed since the lamp was turned on, the function to turn off the lamp was added in Ver2.0.

4. Display of information

 The tree view of the RAID viewer is changed

The Disk Array and the Battery were newly displayed as a node, and the entire tree composition was changed. For detail, see "Tree View".

 The design of the icon used by the RAID viewer is changed

 Use the omission mark in the RAID Viewer and raidcmd. The Logical Drive is displayed as "LD" and

Physical Device is displayed as "PD".

 "Queued" and "Paused" is added to the status of operation

 The update function about information of RAID system is added

Supports "Rescan" of RAID Viewer and "rescan" command of raidcmd as the function which updates the managed information in the Universal RAID Utility in Ver 2.0. Deleted the old "Rescan" function of RAID Viewer of Ver1.4.

5. Log/Event

Starting or Stopping Universal RAID Utility

This chapter describes the procedure of starting or stopping each module in the Universal RAID Utility.

raidsrv service

The raidsrv service is started automatically when your computer is booted and stopped automatically when your computer is shut down. Without operation of the raidsrv service, the Universal RAID Utility cannot operate normally. Neither make the raidsrv service be not started nor stop the raidsrv service.

In case of the operating system is Linux or VMware ESX Server, if the raidsrv service terminates abnormally due to occurrence of an error or a process of the raidsrv service is terminated forcibly, the lock file for avoiding double starts is left. If the state remains, the raidsrv service may not be started.

If this occurs, delete the following file before restarting the raidsrv service: /var/lock/subsys/raidsrv

Starting Universal RAID Utility in Single User Mode

The Universal RAID Utility uses network functions. Accordingly, the Universal RAID Utility cannot be used in the single user mode of Linux and VMware ESX Server without network functions. To use the Universal RAID Utility in the single user mode, first enable the network functions in the following procedure and start the raidsrv service.

Step 1

Step 2 Start the raidsrv service.

Step 3 Check that the raidsrv service is started normally.

If a process ID appears, the raidsrv service is started normally.

Start the network service.
