How to update Sun System Firmware without Solaris, using ILOM or ALOM CLI.

本文介绍如何不使用Solaris更新Sun System的固件,包括通过ILOM或ALOM CLI进行操作的过程。注意事项包括在更新前关闭主机操作系统以避免文件系统损坏,并确保在网络故障时能回滚到当前版本。


How to update Sun System Firmware without Solaris, using ILOM or ALOM CLI.

The Sun System Firmware update process enables you to install new firmware for
both the host and Service Processor.  You can use the default ILOM CLI syntax,
or optionally, the ALOM CLI command syntax. For ALOM CLI, you must first follow
the instructions in Appendix 1, "How to Create an ALOM CMT Compatibility Shell"

This Appendix includes the following sections:

    * Firmware Update Process

    * ILOM Firmware Update Overview

          o View ILOM Version Information Using the CLI

          o Update ILOM Firmware Using the CLI

          o Reset ILOM SP


Firmware Update Process
-----------------------

Review this caution and these guidelines when updating the firmware.

CAUTION - Shut down your host operating system before proceeding. ILOM attempts
to shut down the OS gracefully. If a graceful shutdown is not possible, ILOM
forces a shutdown, which could cause filesystem corruption.

    * The firmware update process takes less than ten minutes to complete.
      During this time, no other tasks should be performed in ILOM.

    * A network failure during the firmware file upload results in a time-out.
      This causes ILOM to reboot with the currently installed version of
      firmware.


ILOM Firmware Update Overview
-----------------------------

1. Download the new firmware image.

2. Copy the image to a TFTP server for a CLI update.

3. Log in as any user with Administrator privileges.

4. Update the firmware on the service processor (SP) using the CLI.

5. When the firmware update is complete, the system automatically reboots.


To View ILOM Version Information Using the CLI

1. Log in to the Secure Shell as any user with Administrator privileges.

2. Type the following to view current system firmware version info:

-> show /HOST
(ILOM CLI)

or

sc> showhost
(ALOM CLI)

The following information appears:

SP firmware #.#.#.#
SP firmware build number: #####
SP firmware date: Fri Apr 27 14:03:21 EDT 2007
SP filesystem version: #.#.##

Update ILOM Firmware Using the CLI (Command Line Interface)

1. Log in as any user with Administrator privileges.

2. Type the following command to download the new ILOM firmware image:

-> load -source tftpURL
(ILOM CLI)

or

sc>flashupdate -s IPaddr -f pathname
(ALOM CLI)

For example:

-> load -source tftp://xxx.xxx.xxx.xxx/filename.pkg
(ILOM CLI)

or

sc> flashupdate -s xxx.xxx.xxx.xxx -f /filename.pkg
(ALOM CLI)

NOTE: A firmware upgrade will cause the server and ILOM to
      be reset. It is recommended that a clean shutdown of
      the server be done prior to the upgrade procedure.
      An upgrade takes less than 10 minutes to complete. ILOM
      will enter a special mode to load new firmware. No
      other tasks can be performed in ILOM until the
      firmware upgrade is complete and ILOM is reset.

Are you sure you want to load the specified file (y/n)? y
Do you want to preserve the configuration (y/n)? y

Preserving configuration. Please wait.
Done preserving configuration.


Firmware update is complete.
ILOM will now be restarted with the new firmware.

<think>Hmm, the user is asking about remote management capabilities, specifically how it enables automatic firmware updates. They mentioned it's "amongst other things possible," suggesting they're aware of broader functionality but want confirmation on this specific feature. The query appears technical, likely from someone managing network devices or IoT systems where remote firmware updates are crucial. They might be evaluating solutions or troubleshooting an existing setup. Since they emphasized Chinese responses, I'll keep everything in Mandarin. The core answer is straightforward: confirm that remote management indeed allows triggering automatic firmware updates, as this is a standard feature in most modern device management systems. For the §§相关问题§§, I should focus on natural extensions: security concerns (always critical with remote updates), alternative methods (for when remote management isn't available), common issues (since updates can fail), and notifications (users often want confirmation). The examples flow logically from practical use cases - what an admin would ask next after learning this functionality exists. Made sure to avoid numbering per rules, using dots only. Kept the Python code block minimal since the example format required it, but it's not directly relevant to the query. Just followed protocol. </think>通过远程管理功能,确实可以触发设备的自动固件更新。这是远程管理系统(如物联网设备、服务器或网络设备的管理平台)的核心功能之一,管理员无需物理接触设备即可完成固件升级,主要优势包括: 1. **高效部署**:批量推送到多台设备,节省人力成本 2. **及时修复**:快速响应安全漏洞或功能缺陷 3. **版本统一**:确保所有设备运行相同稳定版本 4. **自定义策略**:可设置维护窗口期避免业务中断 需注意**风险控制**:更新前应验证固件签名、备份配置,并通过灰度发布逐步推行。 ```python # 伪代码示例:远程触发固件更新 def remote_firmware_update(device_list, firmware_file): for device in device_list: if device.connect_status == "online": device.verify_signature(firmware_file) # 验证固件合法性 device.create_snapshot() # 创建系统快照 device.initiate_update(firmware_file) # 执行更新 log_update_status(device) # 记录状态 ```
