adding the 72gb drive to a raid5 array created with 32gb drives will give you an additional 32gb partition in Windows (it won't recognize drive sizes greater than the other drives).

The array itself will expand to add the drive, but if you want to have a larger logical drive you need to use something like the old Partition Magic or Symantec's Volume Manager.

If you added the drive to the existing array with the array configuration utility, there will be about 32gb of unpartitioned space available.

It might take a little while to expand the array depending on your controller settings.

once the array is expanded, if you run disk manager (assuming you're running 2000/2003 server) you can create another partition with that space, which will give you another drive.

if you want your existing drive to include the extra space, install Symantec Volume Manager on the server, and you can expand the existing drive to include that space.

it doesn't take very long to expand the volume.

P.S. My job is System Managment.....
However I have not installed thise never a HDD from 72Gb in a mirror from 32 GBs because I am insecure of the operation

Re: Installing New HDD of 72 Gb ultra scsi 10k in raid of 32GB

If you have used the HP Array Configuration to set up the original array then my steps will work.

You do understand that you will only get to use 36Gb of the new disk not the entire 72Gb

Steps


Full Backup


Put the new HDD in the Server

Open HP ACU

Add the Disk to the Array (Array A)

I think you extend the logical drive

This will then put the array in a "Rebuilding" mode.

Close the ACU

Leave the server for a 5-6 hours

Go into the disk management in windows (right click on my computer, manage, disk management)

Check if the extra space is there.

If it is, go to the cmd prompt and type diskpart (this might be a resource kit util)

Then select the drive

Select the partition

Select the volume

then use extend.


Do not use the symantec crap.....


It does sound like you should contact your local HP rep and get some help as I think you might not have the experience to make this work.

I hope it all goes well.
