Converting a RAID10 ADM array into RAID10

[muzza9999]

Hi I have a  Apollo XL170r that has a six drive RAID10 ADM array - I wish to convert this to a RAID10 Array, retrieving two HDD, for another task. Can this be done online without destroying the data?  I do not want to reconfigure or add drives to the Apollo R2800 chassis.

I will only attempt this if I am 100% sure that the scenario will work.

End game is four disks in a RAID10 array - two disks in a RAID1 array.

You can use shrink feature of the smart array controller which will allow you to remove the drive,

In this case you can remove two drives:

Syntax

<target> remove drives=[#:]#:#-[#:]#:# where <target>is an array, and the specified physical drives are being

removed to shrink the array

e.g.

array a remove drives=1e:1:12-1e:1:14
