1 disk RAID0 to 2 disk RAID1 in Openmanage - data loss?

Hi all,

I have a PERC 6i card which has an existing 1 disk RAID0 virtual disk configured on it.  I want to add a new physical disk to this virtual disk so that it runs as RAID1.

I'm going through the "reconfigure virtual disk" wizard in Openmanage, and it lets me add the second disk to the virtual disk.  It then asks me the RAID level, which I specify as RAID 1.  However there is no indication of whether, when I press the complete button, it will mirror the existing data onto the new disk, or whether it will wipe the original disk and start a mirror from scratch.

Before I do this I want to be sure there is no chance at all of me losing data - please could anyone confirm?

It will convert the existing RAID 0 to a RAID 1 by simply mirroring the first drive to the second.  This can easily be done without data loss.  There is always the one in a million what-if scenario, so have a backup, but it is a feature built-in to the PERC and is designed to be done on the fly and without data loss.

After the backup, you should convert the type to raid 1 first, I think it will then prompt you to insert the disk that will be the pair and that should define the existing drive as the source of information to which the new disk will be synchronized.

Not sure what controller the process you describe is for, but it is not applicable to converting a single-disk RAID 0 to a two-disk RAID 1 on a PERC 6 RAID controller.  Chris has already shown he is familiar with the correct steps for doing this on a PERC 6 using OMSA.
