ax4-5f and raid migrations

Are you referring this for whole AX4-5 or some particular LUNs or RAID Groups?

I have 4 raid groups each as 11 drive raid 5 arrays and I was windering the possibility of an inplace upgrade of those 4 raid groups to raid 6. Each raid group has 4 luns carved out of them.

Nope, not possible. Moreover, even if you take a back up and thinking to restore all the LUNs after resetting the Configuration to Factory please, be aware that total user capacity will be less than what you are getting in RAID 5.

If you have unused disks, you could create a new Raid 6 raid group, then use LUN Migration to move the LUNs to the new raid group, but you can not convert an existing raid group to a different Raid Type.

Also If I may point out, Ax4-5 array do not support RAID 6.

As RAID-6 is only supported with Flare Release 26 and above on Clariion systems.

Maximum FLARE code for AX series array is Flare Release 23.

sakshi_mathur, RAID 6 is supported on AX4/5 Series that are running 02.23.050.5.703.

Thanks Vipin for the correction.

Yes i see that on AX4-5 from Release 23 RAID 6 is supported.
