rs6000下DVD刻录及如何使用呀？？？

要不要什么工具软件？？

seventh

我在linux下用过，和普通的文件系统使用差不多。
可以cp,mv,touch,rm....操作。想必AIX也该如此吧。

这样可以吗？？？

好像不是吧，还是弄个mkiosfs之类的东西看看。

Procedure: a system backup with  DVD-ram on aix 4.3.3

This document describes which parameters have to be chanced and which sofware is needed to make a system backup on  DVD-ram.

software:

rpm.rte
rpm-3.0.5-30.aix4.3.ppc.rpm
cdrecord-1.9-4.aix4.3.ppc.rpm
mkisofs-1.13-4.aix4.3.ppc.rpm

These packages are present on the AIX Toolbox for Linux Applications for POWER systems cd.
But its much better to get the latest versions from the internet.  
Put these in some install directory on your system.
The versions that i show in this document are the ones that i used at the beginning of 2003 .   


Procedure 1:
Install first the rpm.rte package with help from smit. This is needed because you need to use this program to install the rest of the software.
Below are the panels under smit that i used to install the rpm software:

1.

                                                   System Management

Move cursor to desired item and press Enter.

  Software Installation and Maintenance
  Software License Management
  Devices
  System Storage Management (Physical & Logical Storage)
  Security & Users
  Communications Applications and Services
  Print Spooling
  Problem Determination
  Performance & Resource Scheduling
  System Environments
  Processes & Subsystems
  Applications
  Using SMIT (information only)












2.   
                 Software Installation and Maintenance

Move cursor to desired item and press Enter.

  Install and Update Software
  List Software and Related Information
  Software Maintenance and Utilities
  Network Installation Management
  System Backup Manager

3.

Install and Update Software

Move cursor to desired item and press Enter.

  Install and Update from LATEST Available Software
  Update Installed Software to Latest Level (Update All)
  Install and Update Software by Package Name (includes devices and printers)
  Install Software Bundle (Easy Install)
  Update Software by Fix (APAR)
  Install and Update from ALL Available Software

4.
          Install and Update Software by Package Name (includes devices and printers)

Type or select a value for the entry field.
Press Enter AFTER making all desired changes.

                                                        [Entry Fields]
* INPUT device / directory for software              [installdir]                                           +


The rest is simple. After the enter a list appears of software thats located in your install directory.
Select  rpm and install it with the default options.



Procedure 2:

Don’t use smit anymore en use for the rest of the software installations the rpm command.
You can find the executable rpm command in the directory /usr/bin
Its recommended  to upgrade the rpm package first to the latest version. Use the following command:
rpm –Uvh rpm-3.0.5-30.aix4.3.ppc.rpm



Now its time to install the rest of the needed software.
Commands:
rpm –Uvh cdrecord-1.9-4.aix4.3.ppc.rpm
rpm –Uvh mkisofs-1.13-4.aix4.3.ppc.rpm

Note: I use almost always the update command of rpm.
Because is the software already installed it will be upgraded to the latest version and If its not on the system it will be installed anyway.

Procedure 3:

Making links: With a standard installation there will be a few sample cd and dvd scripts installed.  These scripts are found in the directory /usr/samples/oem_cdwriters/
Two of these scripts must be linked and renamed to the /usr/sbin directory with the following commands:
ln –s /usr/samples/oem_cdwriters/burn_cd_gnu_dvdram   /usr/sbin/burn_cd
ln –s /usr/samples/oem_cdwriters/ mkrr_fs_gnu  /usr/sbin/mkrr_fs

To make the scripts working properly you need two other links.
See the next commands:

ln –s /usr/bin/mkisofs /usr/local/bin/mkisofs
ln –s /usr/bin/readcd /usr/local/bin/readcd

note: You can also change the scripts instead of making the last two links.

Procedure 4:

Change the security limits file:

The command limit –a shows the settings for a particular user.
We need to change the settings for the root user, specially if you have made a default installation.  
The settings are found in the /etc/security/limits file. The file should be changed to the settings below:

default:
        fsize = 2097151
        core = 2097151
        cpu = -1
        data = 262144
        rss = 65536
        stack = 65536
        nofiles = 2000

root:
        fsize = -1
        core = 2097151
        cpu = -1
        data = -1
        rss = -1
        stack = -1
        nofiles = 2000
In my case after this procedure i need to restart the system cause otherwise the changed parameters are not recognized by the system.  Inspite of the fact that the command ulimit –a show the right parameters after i changed the file.

Procedure 5:

Make the system backup with the following command:
mkcd  –d  /dev/cd0  –L

Examples of faults/messages after the sys backup command:

If the system shows this you have no mkisofs link to /usr/bin/mkisofs in the   /usr/local/bin/ directory  or you didn’t install the mkisofs rpm and thats why the link is also missing because there is nothing to link to.
