About Reliability, Availability, and Serviceability Features

Reliability, availability, and serviceability (RAS) are aspects of a system’s design that affect its ability to operate continuously and to minimize the time necessary to service the system.

Reliability refers to a system’s ability to operate continuously without failures and to maintain data integrity. System availability refers to the percentage of time that a system remains accessible and usable. Serviceability relates to the time it takes to restore a system to service following a system failure. Together, reliability, availability, and serviceability features provide for near continuous system operation.

To deliver high levels of reliability, availability and serviceability, the Sun Fire X4500 Server system offers the following features:

■ Hot-pluggable disk drives

■ Redundant, hot-swappable power supplies

■ Environmental monitoring and fault protection

■ Integrated Lights Out Management (ILOM) Sun’s remote management capability

■ Support for disk and network multipathing with automatic failover capability

■ Error correction and parity checking for improved data integrity

■ Easy access to all internal replaceable components

■ Full in-rack serviceability by extending the slides

Hot-Pluggable and Hot-Swappable Components

Sun Fire X4540 Server hardware is designed to support hot-pluggable and hot-swappable components. Hot plugging and hot swapping are cost-effective solutions that provides increased system availability and continuous serviceability for business-critical computing environments, by providing the ability to:

■ Remove or replace a failed or failing component while the system is operating

without service disruption.

■ Increase storage capacity dynamically to handle larger work loads and improve

system performance.

Chapter 1 Introduction to the Sun Fire X4500 Server 9

Hot Pluggable Components Overview

The Sun Fire X4500 server hot-plug technology allows a component to be added, upgraded, or replaced while the system is running without affecting hardware integrity.

Hot-plugging provides the ability to physically add, remove, or replace a hard disk drive while the system is running, and other hard disks in the system provide continuous service. Before a hot-pluggable component is removed from the Sun Fire X4500 server, the component must be taken offline from the operating system first, but does not require that the server be powered off.

On the Sun Fire X4500 server, you can hot-plug the following components:

TABLE 1-4 Sun Fire X4500 Hot-Pluggable Devices (Partial List)

Component Part Number

250 GB SATA 3.5 Hard Disk Drive 541-1467

500 GB SATA 3.5 Hard Disk Drive 541-1468

For instructions on hot-plugging components, see the following:

■ cfgadm Command in Chaper 3.

■ cfgadm(1M) (See the cfgadm(1M) man page for more information.)

Hot Swappable Components Overview

A hot swappable component is a component that can be removed or replaced without affecting software integrity. This means that when a component is removed it does not need to be taken offline from the operating system first.

On the Sun Fire X4500 server, you can hot-swap the following components:

CHAPTER

Software and Operating Environment

The Sun Fire X4500 server supports Solaris 32-bit and 64-bit operating systems. The system is shipped with Integrated Lights Out Manager (ILOM) and Solaris 10 6/06 operating system which includes the newly designed Zettabyte File System (ZFS).

This chapter includes the following topics:

■ “Using the Zettabyte File System (ZFS)” on page 11

■ “Administering ZFS File Systems” on page 12

■ “Integrated Lights Out Manager ILOM” on page 13

■ “Intelligent Platform Management (IPMI)” on page 13

Using the Zettabyte File System (ZFS)

This section provides information about using Zettabyte File Systems (ZFS) on the Sun Fire X4500 server. Concepts such as hierarchical file system layout, property inheritance, and automatic mount point management and share interactions are included in the ZFS Administration Guide, (819-5461). For information on best practices for ZFS go to:

http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide

The Solaris Zettabyte File System (ZFS), is available in the Solaris 10 11/06 OS and delivers file system management capabilities by automating common administrative tasks, protecting data from corruption and providing virtually unlimited scalability. ZFS uses virtual storage pools to make it easy to expand or contract file systems simply by adding more drives.

A Zettabyte File System is a lightweight POSIX file system that is built on top of a storage pool. File systems can be dynamically created and destroyed without requiring you to allocate or format any underlying space. Because file systems are so lightweight and because they are the central point of administration in ZFS, you are likely to create many of them.

About ZFS

ZFS is a 128-bit file system that provides 16 billion times the capacity of 32-bit or even 64-bit file systems. With ZFS, data is protected by 64-bit checksums to provide error detection and correction functionally. It constantly reads and checks data to ensure that it is correct. If it detects an error in a mirrored pool, the technology automatically repairs the corrupted data.

Historically, file systems have been constrained to one device so that the file systems themselves have been constrained to the size of the device. Creating and re-creating traditional file systems because of size constraints are time-consuming and sometimes difficult. Traditional volume management products helped manage this process.

Because ZFS file systems are not constrained to specific devices, they can be created easily and quickly, similar to the way directories are created. ZFS file systems grow automatically within the space allocated to the storage pool.

Instead of creating one file system, such as /export/home, to manage many user subdirectories, you can create one file system per user. In addition, ZFS provides a file system hierarchy so that you can easily set up and manage many file systems by applying properties that can be inherited by file systems contained within the hierarchy.

Administering ZFS File Systems

You administer ZFS file systems by using the zfs command. This command provides a set of subcommands that perform specific operations on file systems. You can also manage snapshots, volumes, and clones by using this command, but these features are covered only briefly in this chapter.

With ZFS you can perform the following administrative functions:

■ Manage Devices

■ Create File Systems

■ Create and Manage Storage Pools

12 Sun Fire X4500/ X4540 Servers Administration Guide • October 2008

■ Create and Manage Volumes

■ Take a Snapshot of a File System or Volume

For more information about ZFS, and for an example of creating a file system, refer to the ZFS Administration Guide, (819-5461).

Integrated Lights Out Manager ILOM

Integrated Lights Out Manager (ILOM) is an Intelligent Platform Management Interface (IPMI) 2.0-compliant Baseboard Management Controller (BMC) that implements Lights Out Management (LOM), including Remote Keyboard, Video, Mouse, and Storage (RKVMS); a Web management interface; a command line interface (CLI); and Simple Network Management Protocol (SNMP).

The ILOM software includes the following:

■ Embedded, hardened Linux OS

■ IPMI 2.0 BMC

■ Platform Control agents diagnostics software

■ RKVMS

Lights Out Management is performed on the Sun Fire X4500 server through IPMItool, a command-line utility for controlling IPMI-enabled devices. For more information about Integrated Lights Out Manager (ILOM, refer to the Integrated Lights Out Manager (ILOM) Administration Guide, (819-1160).

Intelligent Platform Management (IPMI)

Intelligent Platform Management (IPMI) refers to the autonomous monitoring, logging, recovery, and inventory control features implemented in hardware and firmware. There are two major components of platform management: the Service Processor (or BMC) and System Management Software (SMS). Platform status information can be obtained and recovery actions initiated under situations in which system management software and normal in-band management mechanisms are unavailable.

SNMP (Simple Network Management Protocol) is a network management protocol used almost exclusively in TCP/IP networks. It provides remote access by SNMP-compliant entities to monitor and control network devices and to manage configurations, statistics collection, performance, and security on a network

Chapter 2 Software and Operating Environment 13

IPMI messages can be used to communicate with the BMC over serial and LAN interfaces, so software designed for in-band (local) management can be re-used for out-of-band (remote) management simply by changing the low-level communications layer.

The IPMItool is a simple command-line interface to systems that support the IPMI v2.0 specification. IPMItool provides the ability to read the sensor data repository and print sensor values, display the contents of the system event log, and SNMP.

Identifying and Configuring Components

This chapter introduces the tools that let you administer the server and explains how the diagnostic tools fit together.

Topics in this chapter include:

■ “Solaris System Commands” on page 15

■ “Component Configuration Information” on page 22

The Sun Fire X4500 server and its accompanying software contain tools and features that help you:

■ Isolate problems when there is a failure of a field-replaceable component

■ Monitor the status of a functioning system

■ Exercise the system to disclose an intermittent or incipient problem

For detailed instructions on diagnosing the server, refer to the Sun Fire X4500 Server Diagnostics Guide (819-4363) and the Sun Fire X4500 Server Service Manual (819-4359).

Solaris System Commands

Some Solaris commands display data that you can use when assessing the condition of a Sun Fire X4500 server. This section discusses superuser commands that assist in troubleshooting problems with the Sun Fire X4500 server. These commands include:

■ “prtconf Command” on page 16

■ “prtdiag Command” on page 17

■ “psrinfo Command” on page 18

■ “cfgadm Command” on page 19

This section describes the information these commands give you. For additional information about these commands, see the command man pages.

prtconf Command

The prtconf command displays the Solaris device tree. This tree includes all the devices probed by the firmware, as well as additional devices, like individual disks, that only the operating environment software can detect. The output of prtconf also includes the total amount of system memory.

CODE EXAMPLE 3-1 prtconf Command Output

# prtconf -p System Configuration: Sun Microsystems i86pc Memory size: 8096 Megabytes System Peripherals (PROM Nodes):

The prtconf command’s -p option produces output similar to the show-devs command. The show-devs command lists only those devices compiled by the system firmware.
