SCSI Hot Swap Manager

This task was known as ″SCSI Device Identification and Removal″ or ″Identify and Remove Resources″ in previous releases. This task allows the user to identify, add, remove, and replace a SCSI device in a system unit that uses a SCSI Enclosure Services (SES) device. The following functions are available:

vList the SES Devices

vIdentify a Device Attached to an SES Device

vAttach a Device to an SES Device

vReplace/Remove a Device Attached to an SES Device

vConfigure Added/Replaced Devices

The List the SES Devices function lists all the SCSI hot-swap slots and their contents. Status information about each slot is also available. The status information available includes the slot number, device name, whether the slot is populated and configured, and location.

The Identify a Device Attached to an SES Device function is used to help identify the location of a device attached to a SES device. This function lists all the slots that support hot swap that are occupied or empty. When a slot is selected for identification, the visual indicator for the slot is set to the Identify state.

The Attach a Device to an SES Device function lists all empty hot-swap slots that are available for the insertion of a new device. After a slot is selected, the power is removed. If available, the visual indicator for the selected slot is set to the Remove state. After the device is added, the visual indicator for the selected slot is set to the Normal state, and power is restored.

The Replace/Remove a Device Attached to an SES Device function lists all populated hot-swap slots that are available for removal or replacement of the devices. After a slot is selected, the device populating that slot is Unconfigured; then the power is removed from that slot. If the Unconfigure operation fails, it is possible that the device is in use by another application. In this case, the customer or system administrator must be notified to quiesce the device. If the Unconfigure operation is successful, the visual indicator for the selected slot is set to the Remove state. After the device is removed or replaced, the visual indicator, if available for the selected slot, is set to the Normal state, and power is restored.

Note: Be sure that no other host is using the device before you remove it.

pSeries690 specifications

The IBM pSeries690, also known as the IBM eServer p690, is a high-performance server within IBM's line of Power Systems, designed primarily for enterprise-level workloads. Launched in the early 2000s, it distinguished itself as one of IBM's flagship offerings, aimed at delivering exceptional scalability, reliability, and processing power.

At the heart of the pSeries690 is the IBM POWER4 processor, a revolutionary architecture that significantly enhanced processing capabilities. The system supports multiple processor configurations, allowing businesses to customize performance based on their specific applications. Each pSeries690 can be configured with up to 32 POWER4 processors, providing a maximum processing power that is well-suited for demanding enterprise applications, complex databases, and large-scale transaction processing.

One of the standout features of the pSeries690 is its ability to handle massive amounts of memory — up to 1TB of total RAM. This is particularly advantageous for businesses that run memory-intensive applications or require high availability for critical tasks. The server’s advanced memory architecture contributes to faster data access and improved overall system performance.

Additionally, the IBM pSeries690 employs the innovative AIX operating system, which is tailored for high performance and reliability. AIX comes equipped with features such as dynamic logical partitioning (LPAR), allowing resources to be allocated flexibly and efficiently across different workloads. This technology supports virtualization, enabling multiple operating environments to run concurrently on a single physical server, optimizing resource utilization.

The pSeries690 also includes robust fault tolerance and reliability features. Redundant components, hot-swappable parts, and advanced error detection mechanisms ensure that the system remains operational even in the event of hardware failures. This reliability is crucial for mission-critical applications where downtime can lead to substantial financial losses.

Networking capabilities of the pSeries690 are enhanced by support for high-speed connections, including Gigabit Ethernet and the ability to integrate with various network topologies. This versatility facilitates seamless connectivity in complex IT environments.

In conclusion, the IBM pSeries690 remains a powerful and reliable choice for enterprises seeking to manage and optimize their most demanding workloads. Its combination of cutting-edge processing capabilities, expansive memory support, and robust virtualization features makes it a significant player in the realm of enterprise computing. As businesses continue to evolve, the core strengths of the pSeries690, especially in terms of scalability and reliability, ensure that it continues to meet the needs of demanding applications.
