Removal and Replacement

Shutting Down nPartitions and Powering Off Hardware Components

For example, the shutdown -h 240 command will shut down and halt HP-UX on the nPartition after waiting for a grace period of four minutes (240 seconds).

To reboot the nPartition after it is halted, use the MP Command menu’s RS command to restart the nPartition. (This allows the nPartition to reset and boot to its BCH interface; if auto-boot is configured it also boots HP-UX.)

Powering Off Hardware Components

This procedure is for powering off and powering on components that are to be removed and replaced.

Step

1.

Login to the server’s service processor (MP).

Step

2.

If the component you will power off is assigned to an nPartition, then use the Virtual Front Panel

 

 

(VFP) to view the current boot state of the nPartition.

 

 

HP-UX on the nPartition must be shut down before you power off any of the hardware assigned to

 

 

the nPartition.

 

 

Once you are certain the nPartition is not running HP-UX, you can power off components that

 

 

belong to the nPartition.

 

 

Refer to the procedure Shutting Down an nPartition for details on determining the nPartition boot

 

 

state and shutting down HP-UX.

Step

3.

Access the MP Command menu.

 

 

From the MP Main menu enter CM to access the Command menu.

Step

4.

Use the MP Command menu’s PS command to check details about the hardware component you

 

 

plan to power off.

 

 

The PS command enables you to check the status of the cabinet, system backplane, MP Core I/O,

 

 

PCI power domains — or bricks — in the I/O card cage, and cells.

Step

5.

Use the MP Command menu’s PE command to power off the hardware component.

 

 

Using the PE command you can power on or off the cabinet (including all cells and I/O in the

 

 

cabinet), individual cells, or PCI power domains (bricks).

 

 

Using the Command menu’s PE command to manage cabinet power is equivalent to using the front

 

 

panel power switch.

Step

6.

If you need to disable all power in the entire cabinet, you also must disconnect all power cords in

 

 

order to disable all housekeeping power.

 

 

 

 

 

 

NOTE

Ensure that all power cords are labeled to indicate which receptacle each cord plugs

 

 

 

into. Because of power redundancy capabilities it is important that each power cord

 

 

 

plugs into its proper receptacle.

 

 

 

Also, ensure that the cabinet power has been turned off before disconnecting any

 

 

 

power cords.

 

 

 

Step

7.

Perform the hardware removal and replacement procedure for the powered off component.

Step

8.

If needed, reconnect all power cords to the receptacles where they belong.

This architecture is designed to provide continuous uptime, which is crucial for businesses dependent on uninterrupted access to their data and applications. The RP7405 supports up to 4 processors, while the RP7410 can accommodate up to 8 processors, allowing for enhanced compute power and the ability to handle increasingly demanding workloads.

In terms of memory, the RP7405 and RP7410 support significant RAM configurations, making them capable of handling large memory-intensive applications. They are equipped with advanced memory management technology, including ECC (Error-Correcting Code) memory, which helps to detect and correct data corruption, thereby enhancing system reliability.

The servers employ HP's Virtual Partition (vPars) technology, which allows for efficient server consolidation by enabling multiple virtual servers to operate on a single physical machine. This capability enhances resource utilization and simplifies management, thus reducing IT costs while maximizing performance.

HP's Serviceguard clustering software is integrated into both servers, offering enhanced availability through active-active clustering and failover capabilities. This software ensures that workloads can be seamlessly transitioned between servers in the event of hardware failures or maintenance, further minimizing downtime.

Security is also a paramount consideration with the HP RP7405 and RP7410. The servers come equipped with advanced security features, including secure boot, encryption, and an array of compliance certifications, ensuring that sensitive data is protected against unauthorized access.

Additionally, the servers support a wide range of operating systems, including HP-UX, which is optimized for the Itanium architecture. This flexibility allows organizations to choose the operating environment that best suits their application needs.

In conclusion, the HP RP7405 and RP7410 are powerful servers designed for high-performance applications in enterprise environments. With their advanced architecture, extensive memory support, virtualization capabilities, and robust security features, these servers stand out as reliable solutions for organizations seeking to enhance their IT infrastructure while ensuring high availability and performance.
