(Apologies if I've misunderstood the purpose of superuser and posted this in the wrong place, but this seems the most likely place I'm going to get ahead with my issue.)
I purchased a Lacie Big Disk Quadra (with two bays) that was completely original minus the hard drives, so was essentially an enclosure. I repopulated the bays with 2x 1TB drives to bring it back to it's original configuration. Once initialised, the volumes are striped and appear as a single 2TB volume by default.
My goal is simple: I wish to amend this configuration so that the two volumes are in a RAID 1 configuration, and therefore acts as a 1TB (mirrored) volume.
My understanding is that since this device operates via the hardware's RAID controller, the only way to configure the device setup characteristics (to either RAID 1 directly, or into JBOD mode which I can then use to create a software RAID in OS X) would be with Lacie's utility. Here's my issue: after many attempts, trial and error etc, I cannot get the device to show up in the Lacie RAID Manager.
I have done the following:
- checked the firmware is up to date (using Lacie's firmware checker, which would only work in Snow Leopard), which it is
- tried the device with two Macs, booting natively between Snow Leopard and El Capitan on both
- on each system, cycled between each I/O on the device (eSATA, FW, USB)
- tried using v1 of the Lacie RAID manager (the one that runs from an internet browser) that I found on an archived version of LACIE's website
Basically, does anyone have any suggestions on how I can configure this device into RAID 1? I have a working (but not advanced) understanding of RAID in general; so whilst I don't think this would be the case, are there any other methods of configuring RAID device controllers at the hardware level?
Many thanks for any help that can be given - I've been tearing my hair out over this for over 48 hours!
