令人失望的笔记本:Dell Inspiron 710m

2006年3月19日 2 条评论

首先

宽屏

这个东东以前总在宣传里看好像是很高档的样子

(电影、高档电视机大多是宽屏的)

戴尔的这款本本(Inspiron 710m)也是宽屏的

用了一下

感觉四个字:

华而不实

用本本上网的话

如今有哪个网站的设计是为宽屏设计的?

一般都是假设用户的分辨率是1024×168设计的

所以宽屏在看网页来讲

纯属鸡肋

然而

最奇怪的是

这款本本居然没有不支持红外!

如今红外都已经是本本的标配了

这款号称最时尚的本本居然都不支持!

虽然红外用得少

但在没有蓝牙的时候

红外还是很有用的

比如:跟手机通讯

综上所述,此笔记本有两点不爽

1,宽屏华而不实,纯属概念炒作

2,不但没有蓝牙,连红外都没有,真是败笔

升级sun fire v20z的sp的firmware的情况

2006年2月16日 没有评论

按照文档一步一步走
ssh登上这台sun fire v20z的sp
sp update flash all -i 192.168.111.111
此时在192.168.111.111这台update server上看到升级已经开始的log
但是到log显示传升级的image到正在升级的sp上了的时候
发现原来连到运行升级的程序的sp的session居然断了
按照以往的经验
感觉这次升级是失败了
于是停掉update server
又试了n回
都是这样
于是开始怀疑文档:)
终于有一次
当session断掉后
我没有停掉update server
突然某一刻我看update server上的log显示升级过程居然还在继续!!
于是我知道有戏了
果然
再过几分钟
升级完毕
再连上去
系统软件已经是新的版本了

sun fire v20z机器的远程管理

2006年2月15日 没有评论

公司机房有2台巨强的sun fire v20z的机器

这个机器也有远程管理口

一直以来也不知道怎么用的

直到今天出了点事情

如果有远程管理的话就可以不去机房

但是……

所以痛定思痛

我翻了下文档把远程管理配上了

这里是文档,文档来自http://www.sun.com/products-n-solutions/hardware/docs/html/817-5246-16/chap2.html#pgfId-999743

Configuring the Service Processor

The Sun Fire V20z and Sun Fire V40z servers include a dedicated SP for complete server independence and maximum availability of server management. The SP is an embedded PowerPC that provides the following functions:

  • Environmental monitoring of the platform (such as temperatures, voltages, fan speeds and panel switches)

     

  • Alert messages when problems occur

     

  • Remote control of server operations (boot, shutdown and reboot of the server’s operating system, turning the server’s power on and off, stopping the server’s boot process in BIOS, and upgrading BIOS)

     

After supplying AC power to the server, you are ready to begin configuring the SP by setting an IP address and associated network settings for the SP. You can configure the SP network settings by using DHCP or by using a static IP address.

Defining SP Network Settings

This section contains two alternate methods you can use to define SP network settings:

Assigning SP Network Settings Using DHCP

The following procedure describes how to set the SP network settings using DHCP from the Operator Panel. If your network does not use DHCP, or you want to assign a static IP address to the SP, follow the instructions in Assigning Static SP Network Settings.

1. Press any operator panel button on the server front panel (see FIGURE 2-1).

The LCD panel displays the first menu option:

Menu:
Server Menu

FIGURE 2-1 Operator Panel Buttons

2. Press the Forward button until you reach the SP menu:

Menu:
SP menu

3. Press the Select button to display the SP menu options.

SP Menu:
Set SP IP info?

4. Press the Select button.

The following prompt appears with the default response:

SP use DHCP?
No

5. Press the Forward button to change to Yes, then press the Select button.

6. Press the Select button at the confirmation prompt.

SP use DHCP:
Yes?

The server attempts to contact a DHCP server for an IP address. When the server receives a DHCP response, the LCD panel displays the DHCP-assigned SP IP addresses. The SP address is configured and the server is ready for use.

7. Continue with Creating the Initial Manager Account for instructions on creating the initial manager account.

Assigning Static SP Network Settings

From the operator panel, follow these steps to set the SP network settings using a static IP address. You must specify a subnet mask and default gateway. This example uses the following sample settings:

IP Address: 10.10.30.5
Subnet Mask: 255.255.255.0
Default Gateway: 10.10.30.254

1. Press any operator panel button on the server front panel (see FIGURE 2-1).

The LCD panel displays the first menu option:

Menu:
Server Menu

2. Press the Forward operator panel button until you reach the SP menu:

Menu:
SP menu

3. Press the Select operator panel button to display the SP menu options.

SP Menu:
Set SP IP info?

4. Press the Select operator panel button. The following prompt displays with the default response:

SP use DHCP?
No

5. Press the Select operator panel button.

The LCD displays as follows:

SP IP Address:
0.0.0.0

6. With the cursor in the first field, increase or decrease the value using the Back or Forward operator panel button.

This field can hold a value between 0 and 255.

SP IP Address:
10.0.0.0

7. After reaching your desired value, press the Select operator panel button to advance the cursor to the next field.

SP IP Address:
10.0.0.0

8. Repeat Step 6 and Step 7 for each field until the desired IP address is displayed, then use the Enter button combination to save the IP Address.

The process continues to the next network setting, the Subnet Mask. The LCD displays as follows:

SP netmask:
255.255.255.0

9. Edit the subnet mask setting in the same manner as you did for the IP address. When finished, use the Enter button combination to save the subnet mask.

The process continues to the next network setting, the default gateway. The LCD displays as follows:

SP IP Gateway
10.10.30.1

10. Edit the default gateway setting in the same manner as you did for the IP address and the subnet mask. When finished, use the Enter button combination to save the default gateway.

The LCD displays the following confirmation prompt:

Use new IP data:
Yes?

11. Press the Select operator panel button to use the new data, or use the Cancel button combination to disregard.

The SP address is now configured and the server is ready for use.

12. Continue with Creating the Initial Manager Account.

Creating the Initial Manager Account

After you install the server and configure the SP’s network settings, you must create the initial manager account. You can then perform initial configuration of the server and create additional user accounts. Only the administrator who does the initial system configuration can create the initial manager account.

A setup account is included with each server. This setup account has no password. When you log in to the SP the first time using the setup account, you are prompted to define the initial manager account with a password and an optional public key.

Usernames and passwords are strings that consist of any alphanumeric character, underscore, hyphen, or period.

  • Usernames must be unique and must begin with an alphabetic character.

     

  • Passwords can contain any printable character and are case-sensitive.

     

  • A username or a password is limited to 32 characters and cannot be a null or an empty string.

     

There are two methods you can use to create the initial manager account:

Creating the Initial Account From a Command Line

Log in to the setup account and create the initial manager account by following this procedure:

1. Using an SSHv1 or SSHv2 client, connect to the IP address of the SP.

2. Authenticate as the user setup with no password required:

# ssh sp_ip_address -l setup

3. Follow the on-screen prompts to create the initial manager account.

After you create the initial manager account, the setup account is deleted and you are logged out of the server. You can then log in using the new initial manager account, from which you can create other user accounts.

After you create the initial manager account, continue with Defining a Name for the Server or Server Management and Platform Software.

Creating the Initial Account From the SM Console

To create the initial manager account from the SM Console:

1. Enter the SP name or IP address as the URL or address in a browser, to enter the SM Console.

2. At the Create Initial Manager-Level User ID screen, enter a user ID for this account.

3. Enter a password for the account.

4. Re-enter the password to confirm.

5. Click the check mark button.

6. Use the SM Console to select initial configuration options.

After you create the initial manager-level user, the Initial Configuration Checklist screen displays in the SM Console. This enables you to determine the options you want for the initial setup of the SP.

The Initial Configuration Checklist is a table that lists the SM Console menu options and the commands you use to configure each option. It also includes links to the online help that provides instructions for each option.

After you create the initial manager account, continue with Defining a Name for the Server or Server Management and Platform Software.

Defining a Name for the Server

If desired, you can define a name for the server that will be displayed in the operator-panel LCD when the SP is idle. After you define a name, the name and the IP address of the SP alternate every few seconds in the LCD.

1. When the server is in background state, press any operator-panel button (see FIGURE 2-1).

After you press a button, the LCD panel displays the first menu option:

Menu:
Server Menu

2. Press the Forward button until you reach the Panel menu:

Menu:
Panel menu

3. Press the Select button to display the Panel menu options.

4. Press the Forward button until the Name for LCD menu option displays:

Panel Menu:
Name for LCD?

5. Press the Select button to enable data entry.

6. Enter an alphanumeric string to display on the first line of the LCD.

You can enter letters A through Z, digits 0 through 9, hyphen and space.

a. Use the Forward and Back buttons to locate the character you wish to enter in each field.

b. Press the Select button when you locate the character you want.

c. Repeat this process until the entire name is complete.

7. Use the Enter button combination (Forward plus Select) to save your entry.

hp dl380G4的机器安装Fedora Core 3启动不了系统的问题

2005年9月21日 没有评论

公司进了一批hp dl380G4的机器
产品那边非要linux 2.6的kernel不可
那会儿想不出什么版本的Linux有2.6的kernel的发布
而且还比较好一些 就先入为主的用了redhat的Fedora Core 3
没想到安装完成后启动不了机器 去找hp的人
回答是问我们为什么不用as3
我们说我们要2.6的kernel的
hp的人说redhat发布的as3里虽然还是2.4的kernel
但是已经被redhat的人加了好些2.6的特性进去
并说Fedora不在hp dl380G4的支持范围之内
而且还巨罗嗦 知道我们忍无可忍
以这个会影响到我们公司下单为由
他们才老实一些 ^_^
 看来只有靠自己弄咯 去网上搜,发现: http://www.fedoraforum.org/forum/archive/index.php/t-26594.html

按照提示
装的时候用lilo取代grub就解决问题了
