Adding disks for storage on HP ML350 G5

Hi everybody,


We have an HP PROLIANT ML350 G5 running Win sbs2003 sp2 and Array Configuration Utility V. / Firmware V.1.86


The actual disks configuration is:


#2 72GB disks in RAID 1 (OS) (bay 1-2)

#3 146GB disks in RAID 5 (for storage) (bay 3-4-5)


Due to lack of space we decided to add two more disks (bay 6-7) of 146 GB in RAID 1 configuration for storage purposes.

(this update of a few gb is justified by the fact that the server will be fully replaced soon)


The questions are 2:
Disks should be added when the server is off and then configured by BIOS? (or can i hot swap them an then configure trough ACU?)

If yes what is the procedure to follow? 


Other suggestions? (I.e adding space to the current raid 5?)
Attached is the screenshot of the actual situation.




Re: Adding disks for storage on HP ML350 G5

You have several options. And you can do it all on-line.


Ensure that you have a good backup, better safe than sorry.


Do the "upgrade" out of office hours.


Insert the disks.


Open ACU

Now you will have to choose, what you want to do.

Option 1. You can create a new array, with a new logical drive (Riad 1 (1+0)).

Option 2. Expand the Array ( Add the disks to Array B), then create a new logical drive on the new space.

Option 3. Expand the Array, then extend the logical drive (You will get a bigger drive).


Now you will need to open Disk manager in windows.

If you choose option 1 or 2, you will get an extra disk in disk manager. You can choose to span them if you like.

If you choose option 3 you will have unused space on you disk. For win2003 you will need to run diskpart from a command prompt, to extend the disk.


Beware, if you want to extend or span disks, it must be dynamic disks.

Great gregersenj!

Thanks for your kind reply!

So, no need to enter into the Array configuration during the server startup.

I think i will choose the first solution without touching other files or settings at all in the other disks Array.
