SSA RAID Adapter Installation and User's Guide.

Array Problems

4.2 Array Problems

Many problems within an array are not seen by the users of the server. The RAID-1 and RAID-5 functions provide a continuing service to the users even when a member of an array has failed. However, unless the failure is corrected, a second failure within that array could cause the whole array to become unavailable. Therefore, it is very important that you check the error log for the adapter regularly. You could do this by making such a check part of the startup procedure for your operating system.

If you are using OS/2, a pop-up window appears when an error is logged for the adapter or the disk drives attached to it. Also, the pop-up window appears every hour while an error likely to affect the operation of the array remains on the log. The pop-up window recommends that you check the entries in the error log.

To check the error log:

1.Start the configuration utility by executing the following program:

￿For OS/2: ISSACFG

￿For Novell NetWare: load ISSACFG

￿For Windows NT: ISSACFG

￿For DOS: ISSACFG

or, if it is available, double click on the SSA Configurator icon.

2.From the Main Menu, select Event/Error Logger and then Analyze SSA Event Log.

The SRNs (service request numbers) describe the errors.

￿Some SRNs describe errors with the adapter card or with the SSA configuration. These SRNs are listed inAppendix B, "SSA RAID Adapter Service Request Numbers" in topic B.0 with a description of what you should do to solve the problem.

￿Some SRNs describe errors with the SSA disk drives or the units in which they are installed. For a complete description of these, see the Installation and User's Guide or the Maintenance Information for that unit.

If one of the following SRNs appears, you can correct the problem by exchanging a disk drive for a new one:

Any SRN whose first character is '1' 60210

D0100

D0300

The following section describes what you need to do with the array configuration utility while changing a disk drive.

32H3816 specifications

The IBM 32H3816 is a notable component in the landscape of computing hardware, particularly designed for high-performance applications within IBM's extensive lineup of server and storage solutions. This specific model serves as a memory module, contributing significantly to the operational efficiency and performance capacity of various IBM systems.

One of the main features of the IBM 32H3816 is its substantial memory capacity, typically offering up to 16GB of RAM. This amount of memory is crucial for handling large datasets and running multiple applications simultaneously, making it ideal for enterprise-level servers, databases, and virtualization environments. The module's capacity supports the growing demands for resource-intensive applications, setting a foundation for better multitasking and system responsiveness.

Another key characteristic is its memory type, which is DDR3 SDRAM. This technology provides faster data transfer rates compared to its predecessors, ensuring a smoother and more reliable performance. DDR3 allows for improved bandwidth, enabling quicker access to data stored in memory. Its lower power consumption is also a significant advantage, making the IBM 32H3816 a cost-effective choice for businesses looking to optimize energy usage while maintaining high performance.

The memory module is designed with advanced reliability features, such as ECC (Error-Correcting Code) capability. ECC ensures that data integrity is maintained by detecting and correcting common types of internal data corruption. This feature is particularly important for mission-critical applications where data accuracy is paramount. Users can expect enhanced stability and reduced risk of system crashes that could lead to data loss.

IBM has engineered the 32H3816 with temperature and voltage tolerance in mind, which makes it suitable for use in various server configurations. These characteristics ensure that the module functions optimally even in challenging environments, thus prolonging its lifespan. The compatibility with multiple IBM server models also adds to its versatility, enabling businesses to upgrade existing systems seamlessly.

In conclusion, the IBM 32H3816 memory module stands out for its robust capacity, advanced technologies, and reliability features.
