Mirror existing disk into raid1 inside hpacucli

Hi,

I recently installed another disk in the server and want to mirror my existing drive into a raid1 mirror from inside the hpacucli. It is important that i not lose data on the existing disk.

Please see the configuration below.

=> ctrl all show config

Smart Array P400i in Slot 0 (Embedded) (sn: PH88MP2374 )

array A (SAS, Unused Space: 0 MB)


logicaldrive 1 (33.9 GB, RAID 0, OK)

physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 36 GB, OK)

unassigned

physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 36 GB, OK)

I don't think it is possible.

You cannot split an array if it contains logical drives in RAID 0, RAID 5, or RAID ADG configurations.

There is a option in ACU-> Splitting a mirrored array-> This task splits an array that consists of one or more RAID 1+0 logical drives into two identical new arrays consisting of RAID 0 logical drives. This feature is useful when you want to replicate a configuration or when you want to build a backup before performing a risky operation.

May be others can have some idea on this.

I think you want to take a look at this document:

Don't get confused that the SmartArray ecosystem calls a single disk drive a "RAID-0". That's just incorrect terminology, but life isn't perfect ;-)

I cant find any information regarding my question in that document :(

Thanks for your answers though.

Looks like you cannot do it with the CLI.

On top of page 7 it says:
""You must split or re-mirror arrays when the server is offline and operating in the standard configuration mode of ACU.""
