HP Z800 w/ 2.2TB

[Brown, David (Test Dept)]

Matthew,

To see a storage device >2TB it must be initialized using the GUID partition table (GPT) scheme and not the MBR (Master Book Record) scheme.

You cannot use fdisk to partition the disk as it sometimes creates misaligned partitions. Boot with a Linux CD or USB and run (where X is what device your disk was recognized. This example creates an XFS partition but you can use mkfs.ext3, mkfs.ext4, mkfs.ntfs or whatever):

sudo parted
(parted) select /dev/sdX
(parted) mklabel gpt
(parted) mkpart primary 0% 100%
(parted) quit
sudo mkfs.xfs /dev/sdX1

Now you should have a 4 TB XFS file system on /dev/sdX1 to install your OS.

Subject: HP Z800 w/ 2.2TB

I bought a HP Z800 for home use, including NAS, VM's, sandbox, etc. To my chagrin, I have discovered that it will only recognize a max HDD size of 2.2TB. I've gathered that it is used by too-old firmware. However, a member of the HP forum board successfully installed a 3TB drive under Windows, so it seems technically feasible. He recommended updating the Intel controller driver, but HP does not offer a controller driver for Linux derivatives. I'm loathe to make unnecessary changes because I don't want to make anything worse.

Sooooo...does anyone know how to overcome the 2.2TB threshold?

FWIW, HP sold this workstation as RHEL-ready, so it is compatible with Linux.

This is virgin territory for me, so please use monosyllabic words and type slowly.

System Specs: Z800, dual-Xeons, 24GB ram, Ubuntu 16.04 from a USB drive (persistent) and one 3TB WD Red
