Move disks to different StorEdge, keeping RAID

Well, but my question rather relates to the time before mapping something to a host machine 
Problem: Disks are in "new" SE3310. How to tell StorEdge, that those "new" disks (which it correctly identifies and displays as "USED DRV") make up a RAID5, which I could then map to a host (better: which I could then assign a LUN, after having "created" a RAID5 Logical Drive)?

I'm not sure if it's going to recognize the RAID and Data on it or not, because if you attempt to create new RAID array, it will initialize and wipe out your data.
Best bet is, backup your data before you do this movement, and also backup the current storage configuration file .xml
this way, you can restore your configuration and data.

One of the four IBM disks (73.4 GB 10k FRU 06P5760) has become faulty. The system is still up and running OK because of the RAID. In that same EXP300... (3 Replies)

ATARAID(4) BSD Kernel Interfaces Manual ATARAID(4) NAME
ataraid -- software BIOS RAID SYNOPSIS
pseudo-device ataraid ld* at ataraid? vendtype ? unit ? DESCRIPTION
The ataraid driver provides support for BIOS-based software RAID controllers. These are devices which have some simple support for several basic RAID levels (often RAID 0 and RAID 1), but which require software support to actually perform the RAID function. The BIOS support is largely just to create and recognize the array so that it may be a boot device. The driver currently supports RAID formats from: o Adaptec HostRAID (found in Intel 6300ESB) o Intel MatrixRAID o JMicron RAID o nVidia MediaShield o Promise FastTrak o Via V-RAID (found in many VIA-based motherboards) Status of the logical disk as well as the disks associated with it, can be viewed through the bioctl(8) utility. SEE ALSO
ld(4), bioctl(8) HISTORY
The ataraid driver first appeared in NetBSD 2.0. AUTHORS
The ataraid driver was originally adapted from FreeBSD by Jason Thorpe <thorpej@NetBSD.org>. BUGS
Not all features of the software RAID are currently recognized or supported. For example, the Adaptec support doesn't recognize when a RAID 1 should be in a ``building'' state, and it does not do the right thing. At least part of the reason for this is that the publically-available information on these formats is quite limited. BSD
