NEED INFORMATION ABOUT ACU

[taher_1]

Hi,
I am new to HP stuff. Could anybody please give the Documentation or user guide on how to use ACU. Including installing and configuring on RedHat Enterprise Linux 4. I am on HP proliant ML370/ML350 server.

I want to study mainly on INCREASING THE space of RAID1 array as it is almost full.

And all the links to download ACU as i dont have SmartStart CD.

THANX

Hi vivek,
thanx for the links. I want to see how the web pages of ACU looke like as i am completely unaware of this ACU. My operating system is RHEL4. And i just want some tutorial on setting up RAID1 USING ACU. Well this machine is at client and its already configured in RAID1. I need to increase the space by adding two more hard disks in RAID1 to already existing array in RAID1.

Any notes on adding 2 x 148GB hard disks to existing array( of RAID1 2 x 148GB) or links will be appreciated.

Regards
taher

Just to confirm :- Which one did you use? servername or IP address of the host?

I didnt use the Linux version of ACU yet. But the interface should be the same for all.

You can add the drives to RAID one.

http://docs.hp.com/en/9320/acu.pdf. Please see the doc and the steps below:

Login to the ACU.
Expand Array
NOTE: The Expand Array task is listed only if there is an unassigned
physical drive on the controller. The unassigned drive must also have a
capacity no less than that of a drive in an existing array. If these
conditions are not fulfilled, install at least one suitable drive on the
controller, and then click Refresh.
This task increases the storage capacity of an existing array. You can use the
additional storage space to:
â ¢ Create new logical drives ("Create a Logical Drive" in page 46 ).
â ¢ Migrate the RAID level or stripe size of existing logical drives ("Migrate a
Logical Drive" on page 55).
â ¢ Extend existing logical drives on the array ("Extend Logical Drive" on page
50)
IMPORTANT: An array expansion, logical drive extension, or logical
drive migration takes about 15 minutes per gigabyte, or considerably
longer if the controller does not have a battery-backed cache. While this
process is occurring, no other expansion, extension, or migration can
occur simultaneously on the same controller.
1. Click Controller Settings, and verify that the Expand Priority setting is
acceptable.
2. Back up all data on the array. Although array expansion is unlikely to cause
data loss, observing this precaution provides additional data protection.
3. Click Expand array, and then click Begin.
4. Choose the array that you want to expand, and then click Next.
5. Select the physical drives that you want to add to the array, and then click
Next.
6. Click Finish to accept the changes.
At this point (before clicking Save in the next step), you can create logical
drives on the unused space created by the expansion. You can also arrange to
expand another array on the same controller by repeating the previous steps.
However, the controller can expand only one array at a time. Remaining
array expansions are queued.
7. Click Save.
The controller now rearranges (re-stripes) the existing logical drives and their
data so that they extend over all the physical drives in the enlarged array.
To check the progress of an array expansion, click the icon for that array in the
Configuration View panel. A More Information pop-up window opens that
describes the array status
