关于FASTT200的动态扩容的问题,请高手多多指教!

[size=5][size=5][size=6][b][/b][b]我有一台FASTT200的机器,本身有3块73G硬盘在做RAID5,现在想再加2块73G硬盘,在不破坏原来的系统及数据的前提下,在线扩容到原来的RAID阵列里,怎么做?[/b][/size][/size][/size]

新的DS4000是可以的，FastT200就不太清楚了，属于老古董的东西了，有可能firmware不支持

3块盘的RAID5，也真有想象力。。。

在STORAGE MANAGER力，选动态扩展RAID

[size=4]各位老大能不能说的详细一些啊,加我QQ:157157313,万分感谢![/size]

进去一看就知道了，还有啥好说的。。。

一提到动态扩展RAID，心里就怕怕。

3块73G硬盘怎么做RAID5啊，天才了

3块盘为什么不能做RAID5啊

3块盘做RAID5没问题啊，但性能和容量都不好

先备份数据，再进行动态扩容。

DS4000 Best Practices and Performance Tuning Guide sg246363.pdf第362页

Increase DS4000 LUN size in AIX step by step.
This illustration assumes the following configuration:
 Two different logical drives (Kanaga_Lun0 and Kanaga_Lun1)in two separate RAID
arrays on the DS4000.
 The logical drives are seen as two separate hdisk devices (hdisk3 and hdisk4) in AIX.
 In AIX LVM, we have defined one volume group (DS4000vg) with one logical volume
(lvDS4000_1) striped on the two hdisks.
We show how to increase the size of the logical volume (lvDS4000-1), by increasing the size
of hdisk3 and hdisk4 (thus without creating new disks).
Using the SMclient, we increase the size of the DS4000 logical drives by about 20 GB each
(see Figure 11-21 and Figure 11-22).
Figure 11-21 Increase the size - Kanaga)_lun0
Figure 11-22 Increase the size - Kanaga_lun1
You can verify the size of the corresponding hdisk in AIX, by typing the following command:
# bootinfo -s hdisk3
Chapter 11. DS4000 with AIX and HACMP 363
The output of the command gives the size of disk in megabyte, 61440 (that is 60 GB).
Now, stop the application, unmount all filesystems on the volume group, and varyoff the
volume group.
varyoffvg DS4000vg
Modify the volume group to use the new space, with the following command:
chvg -g DS4000vg
Next, varyon the volume group (AIX informs you about the increased disk size).
varyonvg DS4000vg
0516-1434 varyonvg: Following physical volumes appear to be grown in size.
Run chvg command to activate the new space.
hdisk3 hdisk4
Finally, mount all filesystems and restart the application.
You can verify the available new space for the volume group with the command lsvg
DS4000vg. You can now enlarge the logical volumes (Figure 11-23).
