Thank dms for your reply.
But i can't migrate from RAID 0 to RAID 5 because i just buy one HDD. And i can't creat Raid 5 with 2 HDD.
Can you help me migrate from Raid 0 to Rain 1 without data lose
Thank again !

If you currently have a hardware RAID 0 configured,simply add the 2nd disk to existing array and migrate to raid level 1.

But backup before doing that is always a good idea!
Hope this helps

And one more thing - do you a P400 Controller with BBWC upgrade?
You have those options only with the BBWC upgrade:

Management Features
Online array expansion (with BBWC upgrade)
Online logical drive extension (with BBWC upgrade)
Online RAID level migration (with BBWC upgrade)
Online strip size migration (with BBWC upgrade)

Sorry, you mean i can migrate Raid 0 to Raid 1 that without data lose. My data is safe when i migrate?

Only if you have BBWC installed and you need to back up all of your data anyway

hi Tran Hoang

what is your smart array controller? p400? e200?

yes if you already have a RAID 0 you can migrate to RAID 1, that document that dms added (mine by the way jejeje, I need to put my firm in those docs) explain the procedure, so it is the same RAID 0 -> 1 or RAID 0 -> 5

also what dms means is if you have e200 or p400 you will need to buy BBWC for your controller (now I assuming your controller), why because e200 and p400:
Online RAID Level Migration (with BBWC upgrade)
e200

p400
http://h18004.www1.hp.com/products/quickspecs/12400_na/12400_na.html

the point if you dont have BBWC you wont have the option Migrate in ACU like the picture in the document

anything else
just let us know

Hi Karlo
Thank for your reply!
My smart array controller is E200 and i also have a BBWC for my controller. Thus i can migrate from Raid 0 to Raid 1.
But my data in the HDD is very importance with me, and i have never migrate. I want to know my data is ok when i migrate?
My data is OK?
expect your reply, thank again
