Migrate RAID0 to RAID1 online with hpacucli
Can someone confirm me that following will work as expected without data loss, please?
I have the following Linux machine:
Linux server 2.6.9-89.ELsmp #1 SMP Mon Apr 20 10:33:05 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

I would like to add unassigned disk to Logical Drive 1 and migrate RAID 0 to RAID 1. I would like to do it with hpacucli with following commands:
# hpacucli ctrl slot=0 ld 1 add drives=allunassigned
# hpacucli ctrl slot=0 ld 1 modify raid=1
1.) Will it work (I have never tried) with hpacucli (and all documentation I have found describe it using ACU GUI)?
2.) Are the commands correct, is something else required?
3.) Can it performed online (BBWC is available, I guess), while system is running?
4.) How the system performance will be affected? Do you recommend me to lower the rebuild priority to low?
Thank you very much for the comments, if additional information are required, just give me a shout.

Re: Migrate RAID0 to RAID1 online with hpacucli
Just in case someone will be interested in. It works the way described.
In the end I decided to perform it with service interruption and high rebuild priority.
So actual sequence was:
Set rebuild priority to high:
# hpacucli ctrl slot=0 modify rebuildpriority=high
Assigning of unassigned disks to logical drive:
(this action invoked synchronization of RAID with default raid type (of RAID0) - there was only one disk before, right - it took about 1hr (146GB disks))
# hpacucli ctrl slot=0 ld 1 add drives=allunassigned
After synchronization finished, I migrate the RAID0 to RAID1:
(this action took about 5hrs)
# hpacucli ctrl slot=0 ld 1 modify raid=1
Actual answers to the questions in previous post are:
Ad1) yes
Ad2) yes, see the sequence above
Ad3) yes
Ad4) do not know, rather did it with service outage
Hope this helps some one.

Re: Migrate RAID0 to RAID1 online with hpacucli
Just a quick note:
You will need to have a battery cache (BBWC) - that is fully charged - for these commands to work.

Re: Migrate RAID0 to RAID1 online with hpacucli
Has anyone done this successfully in the following conditions?
1. OS Windows 2008
2. 4 300GB with over 500GB of free space?
Thanks,

Re: Migrate RAID0 to RAID1 online with hpacucli
It helped me right now, today! Thanks!
It looks like when I upgraded the P410i firmware from 5.14 to 5.70, along with the disk firmware, it must have dropped the mirror on the logicaldrive and turned it into a RAID-0. Maybe I forgot to power-cycle it, or something.

Re: Migrate RAID0 to RAID1 online with hpacucli
Would it work to first change the RAID type and assigning the spare unasigned hard drive afterwards?
1) hpacucli ctrl slot=0 ld 1 modify raid=1
2) hpacucli ctrl slot=0 ld 1 add drives=allunassigned
This way there is no need to wait until the HDs sync on RAID 0 or to convert two HDs from RAID 0 to 1.
