Removing system disks from a RAID group (cx300)?
I have a raid group that includes every disk my DPE2.
I want to remove the system disks (0-4) from this RAID group.
From what I read I should i put them in their own RAID group and avoid storage user data on them if possible.
Will destroying this RAID group blow out the data on these disc? Would that mean I'd have to re-install FLARE?
No Events found!

Short answer - no. The FLARE OS code resides on a Private area reserved on the Vault drives. You can provision space from the Vault drives, but not the OS area. You can remove LUNs provisioned from the User area on the Vault drives without destroying the FLARE OS region.
Let us know if that helps!

So I can pretty much treat those drives like any other drives (add them to RGs, create luns with them) and I don't have to worry about mangling data in the "private area" of the them were FLARE is stored?
How is this private area designed in the device? Does the cx300 just format the vault drives differently?

The Private area on the disks is a series of small LUNs that are not exposed to the user provisioning tools. Basically, when you add a Vault disk to a RAID Group, the CX "ignores" the private area on the Vault. Think of it like LVM, which allows you to add logical partitions (LUNs on physical disks) to build up larger logical partitions for filesystems. Does that help?
Thanks!
