Re: Swapping 72GB Drives for 300GB Drives within EVA 5000
So, this means that you should keep protection level to none until you group at least 2 300 GB disks. You should add and group disks in pairs of two. Leveling will take a long time, so, when more disks you add at a time, better.
You have to ungroup the disks you want to replace, and then remove the disk using the remove button.
Don't forget to check the controllers and disks firmware.

The EVA might also change the mirror setup for worse when disk drives fail and get replaced - there is no control over this behavior.
I suggest you use a separate disk group, even if this means you lose 600GB for another single sparing.

Re: Swapping 72GB Drives for 300GB Drives within EVA 5000
If you are on >=VCS4.001 or >=VCS3.028 you are ok.
Nevertheless try to upgrade to the latest versions 4.100 or 3.110
Cheers

Re: Swapping 72GB Drives for 300GB Drives within EVA 5000
You find some info about mixed capacities in this EVA3/5000 whitepaper
http://h71028.www7.hp.com/ERC/downloads/4AA1-5215ENW.pdf
Then, to calculate your net capacities I recommend using the HP StorageWorks Sizer from http://h30144.www3.hp.com/SWDSizerWeb/
Install it on your desktop computer then set your preferences.
Use Representation 1k = 1024 bytes in order to get real capacity values!!
On the welcome screen select option 4: Size and ...
Then select Launch EVA ...
Choose array type: EVA5000
Then you can build your array and check out what happens if you change something!!
Cheers
Pete
