Can someone help on below.

Primera A630

Existing is 16 x 1.92TB  drives .need upgrade  around 18TIB using 8 x3.84TB .

Below is summary after upgrde.

Does it support different raid set sizes.

Can we achieve 37 TIB usable capacity after upgrade with this config?

The best practice is to use equal Drive size, but mixing is possible.

By default, the new Disks will be added to the existing cpg, but you can create your own also.

Spare Space will be calculated using the biggest drive.

The sizer should display and calculate this correctly.

Hi Cali,

Thanks for the update.
Disk already added, but does not provide required capacity after upgrade.
Is there any guide for how to create new CPG.
Or do wee need hpe support for this?

Hi,

to create a new CPG based on the Disk Size, use these commands:

You could use a filter based on total chunklets per PD.

e.g.
Get the total chunklet size per PD
Cli% showpd -c

Based on the above output you may need to adjust the switches and chunklet numbers specified below.

Set CPG384 to only use Drive with chunklets >3574
Cli% setcpg -ha mag -sdgs 16g -p -tc_gt 3574 CPG384

Depending on when you installed the drives and set the filters you will probably need to run a tunesys to ensure any current LD's are constrained to the correct CPG's.
