Hi Guys,

I have an HP Proliant ML 270 Server. It already has 3 SCSI 36GB harddisks in Raid 5.

I want to add two more 36GB scsi harddisks and then i want to expand my D partition (i have two partitions C and D).

Is it possible then i could use the HP utility of some type (i'm a rookie in HP array and raid) to add the space of the two 36GB harddisks to the current raid 5 array?

You do not give the generation of ML370, however if it has 3 disks in RAID 5 then presumably it has a Smart Array controller in it. You physically add the disks, then open the Array Configuration Utility and select the array in the central pane, on the right hand pane it should have the options to add disks to array in the right hand pane. Once added and the configuration is saved you can select the logical disk in the ACU and expand appears in the right hand pane. When that finishes (it takes hours) you will see a bigger disk in disk manager (assuming Windows) and you can expand it with diskpart.

Note you should have the latest firmware, drivers and ACU before you start, drivers and ACU comw with the Proliant Support Pack. It's a good idea to make a backup but unless you have Windows 2000 dynamic disks there shouldn't be any corruption.


Thanx guys,

I have windows 2003 exchange server installed in this server. the 2nd partition is D and it is nearly full.

The current Harddisk is "basic" and not "dynamic".  

There is in the windows installed an "HP Array configuration utility" and "Setup hp array confihuration utility".

But the first one is not showing anything in the browser and the 2nd one starts some type of installation wizard.

Is that smart array controller coming when we restart the computer?

Setup ACU lets you put it into local or remote mode, you need it in local mode.

Also check that the SNMP service is running.


Yes andy  i opened this page       https://serverName:2381/     and all the information about all the hardware of HP server is coming. I have already shutdown the server and have put two scsi 36GB harddisks and have rebooted and ran ACU now.

Please tell me from where I shud go and use the disk space of my new drives to add to the existing partition by the name of D Drive.

There is a "login" written at the top right, is it the network administrator account login or does ACU have it's administrator account and it's own password?

right now i am logged in as anonymous.

do i have to login to make any changes in the ACU?
