AIX真J8烂，一大堆命令不支持，麻烦死了

原来的帖子锁了，就是这个

摆渡 ksh for 搜出来的，看了不舒服，挖出来拍两砖

我所见，这个帖，回帖的 风气/人品/技术 真差！
你特么会改个默认脚本解释器有啥了不起的，贴一堆的J8图显摆，就是不说怎么回事，故弄玄虚；
剩下就是一堆跟着讽刺挖苦的，别人是有困难才来的，你们一帮敝帚自珍的大爷作风
那几个出seq主意的同学，态度还是值得表扬和肯定的，但是就没考虑过性能问题么 5个可以这样搞，for 后面 10万个能行么？

回到纠纷的主体，AIX 比 Linux 难用一万倍！
别拿你们管理员怎么牛B可以优化设置说事儿！你们干得那点活搁 Linux 那就一失业的份。
用户只关心体验如何，别找什么借口。

个人觉得这只是关于ksh和bash开发，使用风格和习惯不同所造成的，并不是操作系统本身的问题。AIX上支持绝大多数的shell, 只是由于默认的是KSH, 你可以通过下载你熟悉的shell包，通过修改默认shell配置来使用你熟悉的shell。其实不必牵涉到其他东西。
每个人总有很多不懂得东西，碰到问题学习就是了。共勉

看了那个帖子，说的应该是我吧。09年的事情，还真是怀念~~~
那个时候我记得Linux认个新磁盘，比如SAN LUN都要重启，不知道现在是否有长进了......

我了个去诶，两个楼主还真像嘿
作为一名菜鸟～我表示见到二位楼主的神贴以及贴内回复，我现在更有信心学好AIX了～

AIX是IBM的操作系统，是自成一家的unix，不像linux是开放的，当然会有很多区别。说AIX很烂，只能说明你还对aix还不熟悉。

认盘要重启可以说业余么，不过确实麻烦倒是真的～～
AIX什么都好，比Linux/SOLARIS都要简单，就KSH真他妈蛋疼，换个BASH这样功能强点shell会死啊。

1. Issue
   
2.         * How to remove or add scsi devices online?
   
3.         * Added Three Additional SCSI Devices to System - OS Doesn't Recognize
   
4. 
   
5. Environment
   
6.         * Red Hat Enterprise Linux 5 update 4
   
7. 
   
8. Resolution1. Add new SCSI disk on the server.
   
9. 2. Run the command below as root:
   
10. # echo "scsi add-single-device x y z u" > /proc/scsi/scsi
    
11. 
    
12. x : The HOST of SCSI controller which controls the disk ("N" of scsiN)
    
13. y : SCSI Channel of disk (the value is 0 when it's a single channel; If there are multi-channels, the value is determined by which channel the disk belongs to)
    
14. z : SCSI ID of the disk (the value can be determined by which socket the disk pludged in)
    
15. u : LUN ID of the disk (the value is 0 by default)
    
16. 
    
17. If the values of "x", "y", "z" are not right, the system can not add the disk successfully.
    
18. Check the file /proc/scsi/scsi and determine whether the disk can be added successfully. If added successfully, the content of file /proc/scsi/scsi may contain the information of the new disk. The file /proc/scsi/scsi contains the information of every device which system can recognize. The information includes vendor, model type, media type and so on.
    
19. 
    
20. For example, I add the third disk in my server, and run the command below:
    
21. # echo "scsi add-single-device 0 0 2 0" > /proc/scsi/scsi
    
22. 
    
23. Then check the file /proc/partition, the new disk is recognized. And you can make partitions, format, and use it normally.
    
24. 
    
25. If you want remove a disk online, take the steps below:
    
26. 1. Run the command below:
    
27. # echo "scsi remove-single-device x y z u" > /proc/scsi/scsi
    
28. The meanings of "x", "y", "z" and "u" are the same as mentioned above.
    
29. 
    
30. 2. Remove the disk physically.
    
31. 
    
32. For example, I have a SCSI disk and a SCSI CD-ROM which are both on the motherboard. After booting my computer, the contents of file /proc/scsi/scsi are as follows by default:
    
33. # cat /proc/scsi/scsi
    
34. Attached devices:Host: scsi2 Channel: 00 Id: 00 Lun: 00  Vendor: ATA      Model: Hitachi HTS54168 Rev: SB2O  Type:   Direct-Access                    ANSI  SCSI revision: 05Host: scsi0 Channel: 00 Id: 00 Lun: 00  Vendor: HL-DT-ST Model: CDRW/DVD GCCT10N Rev: A100  Type:   CD-ROM                           ANSI  SCSI revision: 05
    
35. 
    
36. Then I try to remove SCSI CD-ROM:
    
37. # echo "scsi remove-single-device 0 0 0 0" > /proc/scsi/scsi
    
38. Check the file /proc/scsi/scsi again, notice only SCSI disk remained.
    
39. 
    
40. Then add the SCSI CD-ROM back again:
    
41. # echo "scsi add-single-device 0 0 0 0" > /proc/scsi/scsi
    
42. 
    
43. Then I try to remove the only SCSI disk of my computer, as expectation, the system is kernel panic.
    
44. # echo "scsi remove-single-device 2 0 0 0" > /proc/scsi/scsi
    
45. 
    
46. After rebooting, everything is all right.

SA在AIX上装个bash包会死啊？

我觉得KSH很好呀，不能这么说AIX。。。

Aix 比 Linux 难用？

楼主说的是哪款 Linux 啊……
