extending partitions

I have a RAID5 volume with 4 partitions (C: G: H: I)
C: is getting too small and want to extend it and get some space from G which too much free space.

Can I do that through HP Array configurationm Utility or windows Disk management or should I go for a third party?

thanks

Looks like you can replace the pair of 18GB disks that make up Disk 4 one at a time with bigger ones and let it rebuild checking in the ACU to see if it has finished, then extend the logical disk that it is on to take up the rest of the space. Then you'll need something like Partition Manager (www.paragon-software.com/hdm) to shove Y: to the end and then extend C:.

You will need third party, Partition magic , or Acronis DIsk director or similar.

There are also some free ones.

Lastly you can move temp file dir and page files to F: to free up space, as well as delete all the Windows update files and stuff in the Winnt DIr.

That should free up a few .GB

I hope this helps !

so Windows disk management or HP ACU would n't help?

No, since that is for the physical RAID volumes, not the logical partitions created on them.

What OS is this ?

WHat kind of partitions ( Basic, Dynamic etc ).

I hope this helps !

thiis is W2k3 server
and partitions are basic partitions.
If I am not wrong  the partitions are the logical partitions.

when yo have a RAID, you can create as many partition as you want. Correct?

Do you have 4 seperate logical disks or one logical disk split into four partitions? In other words how many disks do you see in disk manager?

I am not aware of the difference between Logical disk and partitions, I thought they are the same.
Let me relate the scenario that I want to happen.

We have RAID5 of 3 physical disks, each disk is 60 GB size, we want to replace them with 100GB for each disk.  I thought by replacing one disk at a time will rebuild a RAID5 of 3 Physical Disk of 100 GB each. After that I will go to disk management and extend the C: partition and make it bigger.

For Now: C: 4 GB , G:40Gb, H:40GB, I: 36GB Which makes 120GB
I want C:10 GB, G:34GB,H:40GB,I:36GB  which makes 120GB

Please tell me if my plan is correct or wrong.

Well you can replace each disk with a bigger one and either extend the last logical disk in the array or create a new one but extending C: is going to be a problem with the other disks or partitions on the way. If it's one logical disk then you can use a third party off-line partition tool to move the data from I: up a bit, then move the next volume up and so on until there is space to extend C: but if it is four seperate logical disks then you have a problem extending the first disk of four.

Now, tell us how many disks you see in disk manager, not how many partitions you have; there's a big difference.

I am not at work right now, but I believe in disk management I could see :
Disk 0= has C and G
Disk1= has H
Disk2 has I

You've expanded that a few time in the past by the looks of it. Moving the data from G: to a new Disk3 should be fairly simple, you can probably reassign the drive letter which makes moving stuff fairly easy. Then you can expand C: to cover all the space used by the current G: drive.

When you get back to work find out what uses G: at the moment, hopefully it's just swap space and source files.

I see

Disk4, Disk5, Disk6

On disk4 I see:
a partition that doesn't have a name it's 36MB size
C: partion with 3.95 GB
Cahe(Y):12.97 Gb

Disk5: Ican see 2 E: partions one 339.18GB and one 1057.80GB
Disk6 : I can see 2 D: partitions 195.32Gb and 48.93 GB


D and E partions are dynamic.
