Re: Create a new RAID 1 with existing hard drive without losing data
Per HPE Smart Array P204i-b Controller Overview, the controller supports Migrate RAID/Stripe Size, A RAID migration allows you to convert a RAID-Ready system into a RAID 0, 1, 5, or 10 configuration, or from a RAID 0, 1, or 10 volume to a RAID 5 volume.
https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-a00020050en_us
For more information on RAID migration, please refer HPE Smart Storage Administrator User Guide
https://support.hpe.com/hpesc/public/docDisplay?docId=c03909334
IMPORTANT: An array expansion, logical drive extension, or logical drive migration takes about 15 minutes per gigabyte. While this process is occurring, no other expansion, extension, or migration can occur simultaneously on the same controller. Controllers that do not support battery-backed write cache do not support this process. As a best practice always take data backup before performing RAID migration.
Steps to migrate RAID 0 to RAIDX (where X is RAID level)
1. Access HPE Smart Storage Administrator.
2. In HPE Smart Storage Administrator, Select the controller, the Logical Devices on the left, the “Logical Drive 1” from “Array A” and then “Migrate RAID/Strip Size”
3.. The below image show what options you have – RAID 5 could be migrated to RAID 0 and RAID 5 Level

Re: Create a new RAID 1 with existing hard drive without losing data
The problem is obviously, the data is on a non-RAID drive (HBA mode).
Hence the suggestion to clone to a RAID0 drive, then migrate RAID 0 to RAID 1.
Hope this helps!
Regards
Torsten.
