How to wipe a power edge t420, 4 array SCSI drive set

Hello All,

 

I recently obtained a power edge from eBay, I have a perc H710 adapter.

 

 

I was wondering the best way of wiping all 4 drives.

Hello rosmersc,

 

RAID5 with 4 drives (the capacity of one drive is reserved for parity),  you can only use the capacity of each drive equivalent to the smallest drive in the array.

146x3=438G

 

If you use just the three 600G drives then you should get near 1.2TB on a RAID5

Hi @rosmersc,

 

There is no preferred way of wiping data. When you create RAID on the PERC, it will prompt if you need to initialize the new RAID creation, just check it and when the process of creation is finished, the PERC will wipe all data on the disk.

I’ve tried to initialize the disks.

 

 

I created a RAID-0, and put four disks in together. I did a slow-init.

It still isn’t wiping it, when I try to create a new virtual disk. It only creates a 500GB disk when it’s suppose to be creating a 1TB disk. This is raid-5, its only creating a 500GB instead of the 1TB is had when I got the machine

Hello rosmersc,

 

What is the capacity of the individual hard drives?

Are they all the same SAS or SATA? You cannot mix those in the same array.

 

Did you use all four drives in the RAID 0 and what size was the array capacity then? 2TB?  (if they are 500G drives)

After you created RAID0 and slow init; Did you delete the array?

When you create RAID5 do you use all four drives?  The resulting size should be 1.5TB (if they are 500G drives)

 

Try this in order:

In the controller Delete array.

Shut down, remove all drives

Boot into controller and reset configuration

Shut down and insert drives

Boot into controller and create RAID5

I have not as I’m at work, I was asking how do I clear the current configuration?

Hi @rosmersc,

 

You can refer to page 48 on how to clear configuration (Deleting Virtual Disks)  https://dell.to/3lKzrzd but make sure the data in the VD is not needed.

They’re SAS-SCSI.

 

 

*3 600 GB Drives

1 146GB drive

 

 

when i try to create a raid 0 or 5 it limits the max size I can make the VD to 500GB.
