HP DL380 Gen8 GPT / MBR problem

[MJIT]

Hello all,

a customer of us has the following problem / situation

1. HP DL 380 with 8 drives, RAID 5, 1 Array, 1 logical volume maximum size
2. Partition divided into 2 (3) volumes : 1 TB system, 1 TB data, no 2 TB not adressed because of MBR partition style

Normally we would use a tool to convert this into GPT style, but afaik this is not possible as HP servers do not support UEFI  / boot from GPT. Is this correct?

Do you see any possibilities to use these not addressed 2 TB?

Thanks for any help, Many regards, Marcus

IIRC windows can do GPT beginning from vista/2003 for non boot drives.

[MJIT]

Yes, thanks for that. Problem is that the whole disk is MBR, please see attached picture.

Now I see ...

It was maybe a bad decision to create a single logical drive, better create multiple logical drives with SSA, so windows can see each logical drive as a individual disk. Such non-boot data disk can use GPT, so you would need a logical small drive for boot and a large drive for data.

[MJIT]

Ok, so that means we have no chance to get around the problem without reinstalling the whole system?

best would be to backup/restore.

However, if your controller supports it, you can shrink the array (logical drive) and create a new drive in the remaining space.
