Server 2012 on HP Proliant : Can't add new disks to existing partition

New Contributor

Hi everybody,

 

because space begins to run low on our main file server (Windows Server 2012 R2), i added 3 more disks (3x 1TB) to the HP Proliant DL380p Gen8 machine.

 

- I used the "HP Smart Storage Administrator" to configure the new disks

- After Rebuild (Raid-5), the Logical Drive in question has now 3 more TB, diagnostics are ok.

 

- In Windows' Disk Manager the new Space appears as "Unallocated" right besides the existing partition.

Unfortunately all options to use the new space, "Extend volume", "New Volume" are greyed-out.

 

How can i use the new space in Windows ?

 

Regards,

G.

Can't tell for sure from here but this looks like maybe an underlying hardware raid with a spanned storage space on top? If so this seems a difficult and complex situation. May have been better off to add the disks to the underlying hardware raid both for simplicity and performance.
