MegaRAID Configuration Console (MCC) This chapter describes the MegaRAID Configuration Console (MCC) and contains these sections: 1.0 "Features and Architecture," 2.0 "Installation," 3.0 "Using the MCC Software Utility," MCC is a software utility that can be run using LSI Logic RAID-aware custom web server. Because of this, no third-party software is required, and the entire code is in JAVA, making MCC platform independent. 1.0 Features and Architecture You would typically configure and administer the arrays and drives using a configuration utility. MCC enables you to connect to a host system and perform the following operations: - Get information about the configuration. - Track the health of the arrays and physical drives. - Track S.M.A.R.T. (self-monitoring analysis and reporting technology) status of the physical drives to monitor drive performance and reliability. - Rebuild an array. - Perform a consistency check on an array. - Check the error log where all drive failures are reported. Note that you need to use the BIOS Configuration Utility to configure arrays, but you can use the MCC to monitor the configuration and perform rebuilds and other operations. A host system has a suite of software running that is controller- and host operating system-dependent. These are (starting from low level and going to high level) the firmware, the drivers, the RAID API, and finally the RAID Server. Any configuration utility resides above this stack of software. MCC is a web-enabled solution for RAID array and drive administration. A user with just a web browser and Internet connection can connect to a host system using LSI Logic custom RAID-aware WebServer or by a WebServer/JSP configuration. Multiple RAID systems can exist on a LAN. The WebServer can be a part of a LAN, which routes the user to the desired RAID system, though the system can work in a Standalone mode, also. Note: You must install Java Run-time Environment (JRE) before you install the MCC for Linux and Windows. The MCC package for Linux is based on JRE and cannot be launched without it. The link to the appropriate download for Java is http://java.sun.com/j2se/1.4/download.html. 1.1 Features The following is a list of the characteristics of MCC: - User-friendly and Web-accessible through an HTML-based graphic user interface (GUI) - Internet browser required (Internet Explorer 5 or higher recommended) - Operating system independent (Client side). - Client side works on all major Internet browsers. - RAID Server works on the following servers: Whistler, Windows NT, Windows 2000, and Linux. - Support for IDE MegaRAID - RAID configuration management - Standard RAID operation management - Alerts and notification management - Co-exists with and enhances existing management environment, such as Power Console Plus. - Dynamic screen updates - Remote adapter/disk firmware installation - Ability to run both in Network and in Standalone modes - Support for all the latest MegaRAID products - Depends on hardware. See the hardware user manual for more information. 1.2 Architecture 1.2.1 MegaRAID Console Server This server holds databases for all registered RAID servers and responds to Internet browser requests. MegaRAID Console server runs WEBRAID and REGSERV programs. 1.2.2 Registration Server (REGSERV) The Registration Server contains a database of all computers that have registered as users of the RAID Server. Before any computer running RAID Server can use the MCC, it must be registered in the Registration Server. This application runs on Red Hat Linux, Windows NT, and Windows 2000. 1.2.3 Registering the Host Machine in MegaRAID Console Server In order to manage several MegaRAID controllers in different machines on the network, the MegaRAID Console Server maintains an internal database of all MegaRAID locations. Each MegaRAID controller must register with the MegaRAID Console Server database. The MegaRAID Console Server internet protocol (IP) address is located in the following files: Windows: %Winbootdir%System32\Drivers\Etc\Regserv.dat Linux: /Etc/host Note: If MCC is running in Stand-alone mode, 'localhost' must be added to the file mentioned above. 1.2.4 Web Server This application runs on MegaRAID Console Server and responds to Internet browser requests. The browser connects directly to LSI Logic specialized RAID-aware Web Server that has the Java Bean built in. By default, installation sets the Web Server port number to 5555. Note: LSI Logic Web Server can co-exist with any other Web Server that you might currently have in your machine. LSI Logic Web Server can be configured to listen to any port you choose, helping to avoid any potential conflict. This solution does not need any third-party software and is totally platform independent. 1.2.5 RAID Server This is the system that has MegaRAID controllers and their monitoring applications, such as RaidServ. RaidServ (called RAID_SERV in Windows NT Service Manager) is a communication layer between MegaRAID Monitoring Console and the IDE software utility and driver. RaidServ is required in all IDE RAID configurations. For IDE, RAIDSERV communicates with the MCC and Spy software utilities to get data about RAID. The RAID Server software runs in any server that has at least one MegaRAID controller and is registered with the Registration Server. 2.0 Installation This section describes the following: - Items required for installation and supported operating systems - Installation procedures for Windows NT, 2000, XP, and Server 2003) - Installation procedures for Red Hat Linux The system must have the items listed in Table 1.

MCC Features and Requirements Feature Requirement -------------------------------------------------------------------------- MegaRAID The TCP stack must be running for the Web Server to Web Server function. There is no requirement for installing Web Server. Web Server is installed in the /opt/LSI directory. There are no RPMs required. The.jar files and directories are simply copied to the /opt/LSI directory. MegaRAID The TCP stack must be running for the Registration Server to Registration function. There is no requirement for installing Server Registration Server. It is installed in /usr/sbin. RegSvr-x.y-z.i386.rpm IDE RAID IDE RAID can be installed only if the "megaraid" driver is detected by the system as loaded. The system checks whether the directory /proc/megaraid exists and is readable. RAID Server: RAID Server can be installed only if the "megaraid" driver is detected by the system as loaded. RSLinux-x.y-z.i386.rpm Spy-rh- x.y-z.i386.rpm Simple network management protocol (SNMP): SNMP can be installed only if the "megaraid" driver is detected by the system as loaded. Spy-rh- x.y-z.i386.rpm exsnmp- x.y-z.i386.rpm Note: See Section 2.6, "How to Install and Extend snmp Agent," for further detail on this feature. 2.2.1 Installing JRE in Linux Systems Perform the following steps to install JRE in Red Hat Linux: Note: Linux is case sensitive, so type all commands exactly as shown. Step 1. Place the CD-ROM into the CD-ROM drive. Step 2. If the CD-ROM is not already mounted, mount it by typing: eject Then place the CD-ROM into the CD drive and type: mount /mnt/cdrom Step 3. If the CD-ROM is already mounted, type: umount /mnt/cdrom Then place the CD-ROM into the CD drive, and type: mount /mnt/cdrom The files on the CD-ROM must be copied to a directory on the hard drive. You can copy these files to an existing directory or create a new directory. Step 4. To create a new directory, type: cd / Then type: mkdir , for example, mkdir java. Step 5. Perform the following steps to switch directories to the CDROM drive, and then copy the files to the directory on the hard drive you want to install into. (Perform these steps in order). a. To switch to the CD-ROM drive, type: mount /mnt/cdrom b. To display a list of the files on the CD, type: ls c. To copy the files from your CD to your hard drive, type: cp * / where destination is the directory on the hard drive you are copying to. For example, cp * /root would copy all the files on the CD-ROM to the directory /root. Step 6. Change to the directory you just copied the files into, and then look at the files in the directory Step 7. Type: cd / Step 8. Type: ls In the directory, you should see a file that ends with ".bin". This is the installation package that you want to run. Step 9. To run the installation package, which creates an RPM file, type: / for example, ./j2re-1_4_0_02-linux-i586-rpm.bin. This creates a file with a similar name with an RPM extension. For example, ./j2re-1_4_0_02-linux-i586-rpm.bin creates a file named j2re-1_4_0_02-fcs-linux-i586-rpm. Step 10. To get a list of files, type: ls Next, you install the RPM package. Step 11. In the directory in which the RMP package was created, type: rpm -ivh for example, rpm -ivh j2re-1_4_0_02-fcs-linux-i586-rpm Step 12. Open .bash_profile to add Java to the path. Step 13. Choose either PICO or VI as your text editor. Step 14. To edit the .bash_profile using PICO, type: cd /root then type: pico .bash_profile Step 15. To edit .bash_profile using VI, type: cd /root then type: vi .bash_profile The following displays on the screen, regardless of the text editor you use: # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin BASH_ENV=$HOME/.bashrc USERNAME="root" export USERNAME BASH_ENV PATH Step 16. Move the cursor to the line that starts with PATH=. Step 17. After PATH=, type: /usr/java/j2re1.4.0_02/bin: This changes PATH=$PATH:$HOME/bin to PATH=/usr/java/j2re1.4.0_02/bin:$PATH:$HOME/bin. Step 18. Save the file and exit. a. If using PICO, press to save the file. When prompted to save the file with changes, click Yes, then press to save as .bash_profile. b. If using VI, type the following to save the file: :wq Step 19. Close the terminal window and reboot. Step 20. During reboot, log on to Linux. The Java installation is complete. 2.2.2 Installing MCC in Linux Systems Perform the following steps to install MCC in Red Hat Linux: Note: Linux is case sensitive, so type all commands exactly as shown. You must install Java Run-time Environment (JRE) before you install the MCC for Linux systems. The MCC installation for Linux systems installs only in the Xterminal screen and does not execute properly in full screen shell (CTRL-ALT-F1). Make sure you install the from the GUI Xterminal screen only. Step 1. Place the CD-ROM into the CD-ROM drive. Step 2. If the CD-ROM is not already mounted, mount it by typing: eject then place the CD-ROM into the CD drive, and type: mount /mnt/cdrom Step 3. If the CD-ROM is already mounted, type: umount /mnt/cdrom then place the CD-ROM into the CD drive, and type: mount /mnt/cdrom The files on the CD-ROM must be copied to a directory on the hard drive. You can copy these files to an existing directory or create a new directory. Step 4. To create a new directory, type: cd / then type: mkdir , for example, mkdir java. Step 5. Perform the following steps to switch directories to the CDROM drive, and then copy the files to the directory on the hard drive. (Perform these steps in order). a. To switch to the CD-ROM drive, type: mount /mnt/cdrom b. To see a listing of files on the CD, type: ls c. To copy the files from your CD to your hard drive, type: cp * / where destination is the directory on the hard drive you are copying to. For example, cp * /root would copy all the files on the CD-ROM to the directory /root. Step 6. Change to the directory you just copied the files into, then look at the files in the directory. Step 7. Type: cd / Step 8. Type: ls In the directory, you should see a file that ends with "jar.zip", for example, a file such as MCCLinux_1.28-7.jar.zip. You need to rename this package so that it only ends with .jar. For example, MCCLinux_1.28-7.jar.zip becomes MCCLinux_1.28-7.jar. Step 9. To change the filename, type: mv For example, mv MCCLinux_1.28-7.jar.zip MCCLinux_1.28-7.jar. Step 10. Install the .JAR package by typing: java -jar <.JAR package name> For example, java -jar MCCLinux_1.28-7.jar Step 11. Go to the Xterminal window or console, and type: SetPass (with the letters "S" and "P" capitalized). Step 12. Enter a password. This is your MMC full access password. This is a case sensitive password, as are all passwords and commands in Linux. Step 13. Close the Xterminal Window. Step 14. Go to the Main Menu/Gnome Menu (the button on the bottom left). Next, if you are using Linux Red Hat 7.2 and 7.3, go to Programs > Start MegaRAID Web Server. If using Linux Red Hat 8.0, go to Extras > Other > Start MegaRAID Server. The MCC displays the version number and which port the console is listening on (it should be port 3570). Leave this program running. Step 15. Open up Netscape Communicator (or Mozilla if you are using Red Hat 8.0). Step 16. Go to URL http://localhost:3570. Your MegaRAID configuration screen displays. The installation procedure is complete. 2.2.3 Uninstalling MCC in Linux Systems Perform the following steps to uninstall MCC in Linux: Step 1. Switch to a graphical user interface (GUI). Access the directory /opt/LSI/_uninst Step 2. At the shell prompt, type: java -jar uninstall.jar Note: MCC installation does not support component updates. You can uninstall a feature and reinstall it. 2.2.4 Configuring Web Server and RAID Servers There are two ways to run MCC. The first is locally, where all the components are in a single machine. The second is in the network, with multiple systems running RAID servers. The following description applies to both. - The Web server is unaware of the registration server. It knows only about RAID servers. - RAID servers are unaware of the Web server. They know only about the Registration server. - Registration server is unaware of both - Web server and RAID servers. There must be only one Registration Server running in the network. It can co-exist with either Web Server or any RAID Server. Of course, in the LOCAL setup, all the components run on a same machine. Perform the following steps to configure Web Server and RAID Servers. Step 1. Registration Server must be running before the RAID Servers are started. Start Registration Server by typing the following at the prompt: /usr/sbin/RegSvr (/usr/sbin/RegSvr -stop to stop) Step 2. Next, make a RAID Server aware of the Registration Server. To do this perform the following steps: a. Open /etc/regserv.dat b. Type either the Internet Protocol (IP) address or the name of the server running the Registration Server. c. If you are using the name instead of the IP address, make sure the name is resolvable. (Try pinging the server using name.) d. If the name is not resolved, you can add the name to "hosts" file. (/etc/hosts) e. If everything is running locally, you can type "localhost" or 127.0.0.1 in the first line of /etc/regserv.dat. The steps above must be done in each machine where RAID Server is running. After that is done, all RAID Servers can be started. Step 3. To start a RAID Server, type the following at the prompt: /user/sbin/RSLinux (Type /usr/sbin/StopServer to stop a RAID Server) Step 4. Web Server must now be made to point at any of the RAID Servers. Perform the following steps to point Web Server to a RAID Server. a. Open the file /opt/LSI/mcc.properties This file contains many NAME=VALUE pairs. b. Locate the name "RAID_SERVER_NAME" c. Type either the name or IP of a RAID Server. d. If you are using the name, make sure it is resolvable. (Try pinging the machine using the name). If the name is not resolved, you can add the name to "hosts" file. (/etc/hosts) e. If everything is running locally, you may type RAID_SERVER_NAME=localhost Step To start WebServer, run: /opt/LSI/startup.sh 2.3 How to Set and Modify the Full Access Password The password must be set on every machine that runs RAID Server (RSLinux). Perform the following steps to set the password for the first time. Step 1. Type /usr/sbin/SetPass at the shell prompt. The SetPass utility prompts you to enter a new password and confirm it. Length of the password must not be more than 40 characters. Step 2. If a password has already been set, you can use SetPass to modify it. The password is maintained in the file /etc/raidpass.val Note: The password needs to be set every time you uninstall and install MCC. 2.4 Log File Information Log files log messages whose severity value is equal or more than the value set in the file /etc/rslinux.cfg. The log files, RSMessages.log and PollMessages.log, are created in the directory /var/log. The file /usr/sbin/RSLinux -ver prints version information. 2.5 Limiting the Size of Log Files MCC contains a feature to limit the size of log files. Perform the following steps to use this feature. Step 1. Open the file /etc/rslinux.cfg. This is basically an INF type of file with parameters in the form of NAME=VALUE. Step 2. Set the maximum size (in bytes) that the log file can be, using the NAME "max_log" field. RAID Server periodically examines the file size and reduces the file to half the maximum size set. For example, if the maximum size is 2 Mbytes, then when the file exceeds 2 Mbytes, it is truncated to roughly 1Mbyte in size. The default value is 1 Mbyte. Step 3. Use the NAME "trim_interval" field to specify the length of time until the next check of the log size. This check is to determine whether the log file needs to be reduced in size. The default value is 120 minutes. The oldest messages are deleted first. 2.6 How to Install and Extend snmp Agent To install and extend the snmp (simple network management protocol) agent, perform the following steps: Step 1. Get the source code of standard snmp and copy it in your machine. a. Download the file 'ucd-snmp-4.2.1.tar.gz' from the download section on the site 'http://netsnmp. sourceforge.net/'. b. Copy the file under '/usr' directory. c. Uncompress it using 'tar -zxvf'. This creates a directory 'ucd-snmp-4.2.1' Step 2. Compile the source and install the standard snmp agent. a. Go to the directory '/usr/ ucd-snmp-4.2.1'. b. Run configuration using './configure' (you may need to press enter 4-5 times). c. Run 'make' to build the agent. d. Run 'make install' to install it Note: The step2 installs the snmp agent (i.e. snmpd) under '/usr/local/sbin/'. In Linux you may have another snmp agent (i.e. snmpd) under '/usr/sbin/' with standard distribution. Don't confuse it with this. Step 3. Extend the snmp agent for 'Spy' support. Install the rpm file exsnmp-2.0-9.i386.rpm using "rpm -i exsnmp-2.0-9.i386.rpm" which will do the following: a. Copy the file 'MegaRaid.so', which is a dynamic link library to communicate with spy, under /lib b. Copy a proper snmp configuration file spysnmpd.conf under /etc/snmp/. The file spysnmpd.conf contains an entry "dlmod MegaRaid /lib/MegaRaid.so" (at the very last line). You can use this to obtain IDERAID information can through the 'Spy' daemon. Step 4. Run the extended snmp agent Note: If the snmp agent is already installed in the machine (e.g. in Red Hat Linux you may have it already) then step 1-2 is not required. a. Make sure 'Spy' is running before starting the snmpd agent. Then stop and start the agent using '/etc/rc.d/init.d/snmpd -c /etc/snmp/ spysnmpd.conf' b. You can test the agent using: 'snmpwalk localhostpublic.iso.org.dod.internet .private.enterprises.3582.1' 5.3 Using the MCC Software Utility This section describes the MCC software utility. You can use the software utilities that come with MCC to perform the following actions: - Get information about the configuration. - Track the health of the arrays and physical drives. - Track S.M.A.R.T. status of the physical drives. - Rebuild an array. - Perform a consistency check on array. - Check error log where all drive failures are reported. To log onto the RAID Server, enter the Internet address in the Internet browser. The MCC screen displays. Click the server name to select the RAID Server you want to configure. Continue the log-on procedure by selecting View Only or Full Access. Table 3 describes the access options. Table 3.
