A.3 Featured Highlights This section explains in greater detail the important features of Altos RAIDWatch. A.3.1 Graphical User Interface Altos RAIDWatch’s graphical interface is designed for ease-of-use.
Altos RAIDWatch User Guide The enclosure window also includes Logical view as a sub-function. The Logical view displays the logical relationship among member drives of a logical configuration. Drives belonging to the same logical unit will be displayed in the same color for ease of identification. A.3.3 Powerful Event Notification Function Altos RAIDWatch can notify system administrators of event occurrences and status changes in the disk array system.
Introduction A.4 Conceptual Foundation In order for Altos RAIDWatch to function properly, different software modules must be correctly installed on different servers and stations in a given LAN or WAN. Assuming that a given network has multiple RAID systems, one RAID connected server will need to be chosen as the main server. This point is particularly important if Altos RAIDWatch will be operated via web browsers as the main server will need to be a web server.
Altos RAIDWatch User Guide Notes 1 OS drivers are required for Solaris servers. 2 OS patches are required to run JRE on Solaris, AIX and Linux servers. 3 Browser preferences must be edited for browsers running under Windows systems. The requirements for installing Event Monitor are exactly the same as those for Altos RAIDWatch Manager.

The NPC Chapter 11 The Notification Processing Center The Notification Processing Center (NPC) is a notification application that enables users to configure notifications that are transmitted when various disk array events occur. The NPC makes it possible to manage (or monitor) the disk array system even when the administrator is away from the manager station. When properly configured, this function can notify the administrator of event occurrences in a RAID array instantly.
Altos RAIDWatch User Guide 11.1 Before You Begin 11.1.1 About NPC Altos RAIDWatch NPC provides five methods of sending notifications: • • • • • Fax Pager E-mail Broadcast SNMP Traps You can use any or all of the notification methods mentioned above. In order to use a particular method, you must have the proper hardware (like a modem for pager notification) and software (like Windows NT with the window messaging subsystem for e-mail message notification) installed in your system. 11.1.
The NPC 11.3 Redundant NPC Modules Figure 11–1 Redundant NPC Modules The NPC and Primary Agent should be, as shown in Figure 11–1, installed redundantly on two different servers in case the Primary Agent or NPC module should fail. If the Primary Agent or NPC should fail, the Primary Agent and NPC installed on another server will continue event notification.

However, it is recommended to log in as an Administrator. For normal users to send faxes, you may check your write access in the registry key: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Print/Printers/Fax/.
The NPC Figure 11–5 4 : FAX Topology Add Fax Mail Transport and Internet Mail as the active services to Windows Messaging profile. Figure 11–6 Add Fax Mail Transport and Internet Mail Since NPC depends largely on the fax service installed to the MAPI of Windows NT for the delivery of fax messages, most fax notification parameters are configured through this software package.
Altos RAIDWatch User Guide • Initializing String: is a standard AT command set initialization command string. The default is &F1X0M0 and should be appropriate for most modems. If you need to change it, consult your modem manual for the correct AT command string. The Initializing String is applied for fax and pager service on Unix-based systems. When you have finished, click Add to have NPC send event notifications to this fax machine.
The NPC Note Under some circumstances, software component necessary for running NPC under RedHat "rpc.rwalld" - may be absent from system.

Event Monitor Chapter 12 Event Monitor This chapter discusses how to configure and use the Event Monitor. Topics include the following: • Summary of the Event Monitor features, 12.1. • Before you begin, 12.2. • Sharing the Event Monitor, 12.3. • Exiting the Event Monitor, 12.4. • Connecting and disconnecting from a disk array, 12.5. • Using the Event Monitor, 12.6. • Severity levels, . The Event Monitor is designed to run as an all-time monitor of the events reported from multiple RAID systems.
Altos RAIDWatch User Guide 12.1 Event Monitor Features 12.1.1 Feature Summary The list below summarizes Event Monitor: • Concurrent monitoring of multiple arrays • RAID controller real-time event notices provide information about various event occurrences, including the time when an event occurs, event severity, and event description • Displaying record of up to1024 events per connection to a controller.
Event Monitor 12.2 Before You Begin • Event Monitor must be installed with Altos RAIDWatch Manager. Executing the program does not require running Altos RAIDWatch Manager program. However, RAID agents are necessary to be running as the communication bridges between controller and RAID servers. • Event Monitor can be running locally or remotely via browser. • When running remotely via browser, Java Applet will be started. Connection to an http server providing "GREM.htm" is necessary.
Altos RAIDWatch User Guide • Event Monitor requires at least one disk array to be operating normally and Altos RAIDWatch Primary and Secondary agents installed on a main management server. Other requirements for running Event Monitor are identical to those required for Altos RAIDWatch Manager. 12.3 Starting Event Monitor 12.3.1 Starting Agents and NPC Agents must be started before running the program. The Event Monitor is unable to display system events when agents are not running. 12.3.1.
Event Monitor 12.3.2 Running the Program: The program can be started in two different ways: 1 executing browser accessible HTML file (GREM.HTM); or, 2 running locally as an executable Java program (GREM.jar). Any computer with a Java Virtual Machine can run this program. 12.3.2.1 Remote: as Java Applet An applet is a program written in the Java programming language that can be included in an HTML file. Start your browser to view the GREM.HTM that should be available on the Primary Agent host.

If you are running Event Monitor at the Primary Agent host machine (i.e.
Altos RAIDWatch User Guide 12.5 Connecting and Disconnecting from a Disk Array One benefit of Event Monitor is that the program can be installed as a permanent window on array status. Before system monitoring can be performed on a particular disk array system, you need to first establish the connection between your management station and the Primary Agent host. Once the connection is established successfully, system events can be displayed.
Event Monitor Figure 12–2 3 Select the IP Address The connection is successful when the list of events shown in Figure 12–3, appears and the Physical view and logical unit subtrees appear in the Navigation Panel. Figure 12–3 Event Monitor Window 12.5.2 Connecting to a RAID System from a Distant Host 1 From the Connect menu, select Open. Repeat this process to select all the Primary Agent hosts.

Altos RAIDWatch User Guide Figure 12–10 Event List There are two sorting methods that can be used to arrange the data in a preferred order. The first is by selecting the relevant button at the top of the event list. If you wish to sort your events into their categories, or according to their dates, select the appropriate button and the event list will automatically be rearranged.
Event Monitor • The Interval drop-down list allows you to confine event display by the date and time of occurrence. Select All, From, Until, or Interval. The time frame of event occurrence can be defined in the scroll lists From and To below. • You may want to compare system events between two controllers. Press and hold down the Ctlr key and select both controllers by mouse clicks. Events of the two disk arrays will be listed in an ascending order. 12.6.

It includes the following topics: • Common oversights, B.1 on page 177. • Error codes, B.2 on page 178. • Error messages, B.3 on page 179. B.1 Common Oversights Check the following first before you run Altos RAIDWatch or if you are having trouble. 1 Check Platform Requirements Review section 2.
Altos RAIDWatch User Guide 3 Check the Primary and Secondary agents #ps -eaf|grep primary #ps -eaf |grep secondary If either program is not running, please open a terminal session and run it manually. IP Settings: Each RAID host server must have a unique IP address assigned. Check the IP address of each RAID host. Also, each Secondary agent IP and TCP port setting must be listed under the Primary agent’s configuration.
Troubleshooting What You Can Do: Check your network environment to determine whether or not the Primary agent is available. Use a “ping” utility to see if the server exists on the network. Code: RC=2 • Meaning: The Primary agent did not understand the last Altos RAIDWatch Manager command. What You Can Do: Please check the firmware version of controller to see if it is compatible with your version of Altos RAIDWatch. Altos RAIDWatch currently only works with firmware versions 2.23 or 3.11 and higher.
Altos RAIDWatch User Guide Explanation: Please assign one PID to each drive channel. • Message: Channel settings failed! Explanation: Please check the channel settings. • Message: Drive channel can only have one ID! Please remove ID from PID list first, and then add. Explanation: Please remove the current ID from the PID list first, then add the new one. B.3.
Troubleshooting • Message: Setup redundant controller failed! Explanation: Check the redundant controller configuration. See if the PID and SID of drive and host channels are all correct and if the logical drives (volumes) are correctly assigned. All other Altos RAIDWatch Manager error messages should be fairly self-explanatory.

RAID Levels Appendix C RAID Levels This appendix provides a functional description of Redundant Array of Independent Disks (RAID). This includes information about RAID and available RAID levels. C.1 RAID Description Redundant Array of Independent Disks (RAID) is a storage technology used to improve the processing capability of storage systems. This technology is designed to provide reliability in disk array systems and to take advantage of the performance gains multiple disks can offer.
Altos RAIDWatch User Guide 2 GB Hard drive 3 GB Hard drive 1 GB Hard drive 2 GB Hard drive 2 + 3 + 1 + 2 = 8 GB Logical Drive C.3 RAID 0 RAID 0 implements block striping where data is broken into logical blocks and striped across several drives. Although called RAID 0, this is not a true implementation of RAID because there is no facility for redundancy. In the event of a disk failure, data is lost.
RAID Levels In disk mirroring, the total disk capacity is equivalent to half the sum of the capacities of all SCSI drives in the combination. Thus, combining four 250GB SATA drives, for example, would create a single logical drive with a total disk capacity of 1TB. This combination of drives appears to the system as a single logical drive. RAID 1 is simple and easy to implement; however, it is more expensive as it doubles the investment required for a non-redundant disk array implementation.
Altos RAIDWatch User Guide C.6 RAID 3 RAID 3 implements block striping with dedicated parity. This RAID level breaks data into logical blocks, the size of a SCSI disk block, and then stripes these blocks across several drives. One drive is dedicated to parity. In the event a disk fails, the original data can be reconstructed from the parity information. In RAID 3, the total disk capacity is equivalent to the sum of the capacities of all SCSI drives in the combination, excluding the parity drive.

Glossary Glossary Fibre (Also known as “fibre channel.”) . A device (in the case of RAID, a data storage device) protocol capable of high data transfer rates. Fibre channel simplifies data bus sharing and supports not only greater speed, but also more devices on the same bus. Fibre channel can be used over both copper wire and optical cable. Fiber . An optical network data transmission cable type which is unrelated to fibre channel (above). HBA Host-Bus Adapter .
Altos RAIDWatch User Guide Parity . Parity checking is used to detect errors in binary-coded data. The fact that all numbers have parity is commonly used in data communications to ensure the validity of data. This is called parity checking. Primary Agent . The Altos RAIDWatch module which manages secondary agents and supports both NPC and Altos RAIDWatch Manager. RAID Redundant Arrays of Independent Disks (Originally “Redundant Arrays of Inexpensive Disks”).
Glossary Write-back Cache . Many modern disk controllers have several megabytes of cache on board. Inboard cache gives the controller greater freedom in scheduling reads and writes to disks attached to the controller. In write-back mode, the controller reports a write operation as complete as soon as the data is in the cache. This sequence improves write performance at the expense of reliability. Power failures or system crashes can result in lost data in the cache, possibly corrupting the file system.
