Chapter 1: Introduction Promise Array Management (PAM) is a utility application designed specifically for monitoring and managing Promise Technology RAID products. PAM runs over a local area network and makes possible RAID monitoring and management from any computer on the network and even over Internet. This allows your IT manager to watch your RAIDs and take care of them over the network. PAM Components There are three components to PAM.
Promise Array Management How They Work Together The Promise Array Management (PAM) utility provides an easy way to set up, monitor, modify and repair your RAID. PAM works with the Promise FastTrak card, SuperTrak card and UltraTrak RAID subsystem. PAM watches the RAID and when significant events happen, or it discovers a problem, the Message Agent sends a warning to the Message Server. The Message Server passes the warning along to all PCs running the Monitoring Utility.
Chapter 1: Introduction PAM Installation Options Following are some examples of ways you can incorporate PAM into your network and RAID systems.
Promise Array Management and also on remote PCs connecting to the company network through the Internet. With this arrangement, you can monitor RAID condition and activity from offsite, such as a hotel room or home office.

Chapter 2: Installation To install Promise Array Management (PAM) is an uncomplicated procedure, once you understand your systems and how you want to use PAM. The purpose of this Chapter is to help you plan and carry out your installation of PAM. By way of review, PAM consists of three components: • Monitoring Utility • Message Server • Message Agent These were described in the previous chapter. Before proceeding with the installation, you must know which component goes where.
Promise Array Management If your company has networked RAIDs and Internet access, you may choose to install the Monitoring Utility on a laptop or home-based PC for dial-in remote access. Limit your installation to the computers of RAID users and your IT administrator. PAM features password protection to further limit access and provide security of your data.
Chapter 2: Installation Message Server The Message Server installs onto the RAID PC if your installation does not involve a network. If you want run PAM over a network, install the Message Server on one of your networked computers including a file server, a networked PC or the RAID PC. Only one installation of the Message Server is required for PAM to work over a network.
Promise Array Management Operating System Support PAM is a utility designed to run on top of previously installed Promise controller card and RAID products. Generally, if your PC runs the Promise card or RAID properly, it will run PAM also. Promise Technology recommends Windows NT 4.0, 2000 and XP Professional to take full advantage of all the features of PAM. In some cases, you can run PAM on other Windows operating systems.
Chapter 2: Installation Installation Procedure Before you start… If you are installing PAM to run over a network, determine the computers and servers onto which you will install PAM. Obtain the IP addresses of all RAID PCs where PAM will be installed. UltraTrak Users The UltraTrak is an external enclosure and must be online during PAM installation. Follow these steps before you install PAM: 1.

Promise Array Manager Controller The Controller deals with creating new Arrays, reading events from the memory buffer, setting cache and performance options. Array creation is covered in the Arrays section of this chapter. Memory Buffer Events The Controller’s Memory Buffer records all the events that happen on the RAID, classified as Errors, Warnings and Information. These are very useful for diagnosing and solving problems on your system.
Chapter 5: Monitoring and Maintenance Controller Options The Controller has system information and settings for disk cache and performance features. Click on the Controller icon in Tree View to see the Options in Information View. SuperTrak Options Figure 5-13. Controller Options for SuperTrak.
Promise Array Manager Rebuild Setting High priority (box checked) assigns most of the system resources to rebuilding. Rebuilding goes faster, restoring redundancy sooner but read/write requests are handled slower. Low priority assigns most of the system resources to handling read/write requests. Read/write requests are handled at nearly normal speed while the rebuild takes longer. See Rebuild an Array later in this chapter for more information on the rebuilding process.
Chapter 5: Monitoring and Maintenance FastTrak Options Figure 5-14. Controller Options for FastTrak. System Information This information is not intended for the user. It may be useful for troubleshooting as directed by Promise Technical Support. Disk Parameters: Enable Hard Disk’s Write Cache Increases hard disk performance by writing data to the cache first and later to the disk. Caution You can lose data if a power failure occurs while data is still in the drive’s cache.
Promise Array Manager Disk Parameters: SMART Check SMART, an acronym for Self-Monitoring Analysis and Reporting Technology, is a feature of the disk drive software. It monitors the internal performance of the drive and reports to the PC when it finds a potential failure. SMART warns you of a developing drive failure so you can replace the drive before it actually fails.

When the Array Status field shows Functional (right), reboot your computer. Note You cannot read or write to a newly created array until it is done synchronizing and you have rebooted your computer.
Chapter 5: Monitoring and Maintenance Scheduled Array Synchronization Promise uses the term synchronization to mean an automated process of checking and correcting data and parity. It applies to RAIDs 1, 0+1, 3 and 5. Synchronizing takes place when an array is first created and then, optionally, on a regularly scheduled basis to maintain content integrity. Scheduling Schedule a time for synchronization when the RAID is least busy reading and writing data.
Promise Array Manager On-Demand Array Synchronization To synchronize an Array immediately, do the following: 1. In Tree View, right-click on the icon you want to synchronize. of the array 2. Select Synchronize from the popup menu. OR click the Synchronize Array button Toolbar. in the While the Array is synchronizing, it is still available to read and write data. If the beeper is enabled, it will beep slowly during this process.
Chapter 5: Monitoring and Maintenance Figure 5-13. An Array in Critical condition (left) and restored to Functional condition (right). Normally, the rebuild process begins automatically when you repair or replace the faulty disk drive. The Array recognizes the drive and begins the process a few moments later. If your RAID has a hot spare, the rebuild begins without waiting for a replacement drive. Be sure to replace the faulty drive as soon as possible.
Promise Array Manager Tree View and Information View display the progress. Figure 5-21. Rebuilding in Progress (left) and completed (right). When the rebuild is complete Tree View returns to normal and Information View displays Functional. The following popup appears: Figure 5-22. Rebuild Successful.

Promise Array Manager There are two options you can specify for an Array: Automatic Sequential / Random Access Detection This option is only available for SuperTrak SX6000. When enabled (checked) the read-ahead cache determines if a sequential or random input/output event is occurring and optimizes itself accordingly. Optimizing results in better array performance. Enable Write Back Cache Write back cache accepts write data from the CPU and holds it briefly in cache memory.
Appendix IP Address In order for PAM to be configured over a network, you must know the IP (network) address of every component. The Message Server uses IP addresses to communicate with the Message Agent on the RAID PCs and the Monitoring Utility on the network PCs. Windows XP To find the IP network address, go to Start > Control Panel > Network Connections > Local Area Connection > Support tab. Figure A-1. Local Area Connection Status dialog box and Support tab.
Promise Array Manager Earlier Windows Systems This procedure also works on Windows XP. To find the IP network address, go to Start > Programs > Accessories > Command Prompt. Type IPConfig and press Enter. Figure A-2. Use the Command Prompt to find your PC’s IP address. Locate and record the IP addresses of all PCs and Servers on your network that will work with PAM. This document will help you recall individual PCs when it is time to specify their connections.
Appendix DHCP Issues Referring to Figure A-1 above, note that it says Address Type: Assigned by DHCP. This means that a DHCP server gave this IP address to this PC when the PC connected to the network. DHCP stands for Dynamic Host Configuration Protocol and refers to software that allows a file server to assign IP addresses to computers on the network. DHCP is very helpful in reducing the number of IP address a company or organization requires.
Promise Array Manager Operating System Support Promise Technology recommends Windows NT 4.0, 2000 and XP Professional to take full advantage of all the features of PAM. The table below shows which versions of Windows work with specific Promise products and PAM components.
