Disks substitution on EVA6000

Hi, I have a Disk Group with 48 disks of 146 Gb.
I bought 10 disks of 300 Gb.
I have only 6 free slot.

How can I reduce first Disk Group to 44 disk? I would create another disk group with 10 disk of 300...
My EVA 6000 is in production.
(Sorry for my english)
Thanks.

Re: Disks substitution on EVA6000

Assuming you have enough free capacity - you would ungroup 4 of your 48 146 GB drives. Once the ungroup operation has completed (this could take many hours), you can safely remove those 4 drives. Then simply insert the new 300 GB drives and form a new disk group.

I'n not sure though how you can have 48 disks with 6 free slots in an EVA. There's 14 slots per shelf so if you had 4 shelves and 48 disks that would be (14 x 4) - 48 = 8 free slots.

Because I have other 2 disk group.
One with 40 disks of 250 Gb and another with 18 disks of 500 Gb.

How can I copy my data from one to another disk group very fast?
I need to move my data after new disk group creation...

Re: Disks substitution on EVA6000

The fastest option would be to create a virtual disk snapclone, but you need business copy licenses.

"The fastest option would be to create a virtual disk snapclone, but you need business copy licenses."

You can get a 60 day demo BC license.

Can someone help me for this?
Where can I create this clone? In Command View?
Thanks

Re: Disks substitution on EVA6000

Hi,
Yes the option is in command view but you will ONLY be able to do this if you have the BC license.
To perform a snapclone:
In command view select the drive you wish to copy. Look at the top of the pane and you should see the "snapclone" tab. Click on this and select what you require.
Snapclones can be created from a different disk group, just select your new group, assuming that you have created it first.
Something important o bear in mind BEFORE you start the snapclone. Snapclones are a "point in time copy" so if files change while the snapclone is in progress then the updated file WILL NOT be copied when it is modified. The file will be copied as it was when the snapclone was started. To do this the EVA does a copy before write. You might also wish to stop all access to the virtual drive before you begin the snapclone as well for the same reason as you may well have open files.

Re: Disks substitution on EVA6000

Hi again,
Forgot to ask:
what version of XCS code are you using?
With XCS 6 and Command View V6.0.2 you can do a mirrorclone.
This is what it says it is, a mirror of the virtual disk you wish to copy. Use command view as I stated above & select the mirrorclone tab instaead. Select options as required.
The difference is:
Once the mirrorclone has completed you can "fracture" [HP term] by selecting the fracture tab. You will now have a complete upto date copy of your parent disk up to the point of the fracture. Remember to close files etc before you do the fracture bit.
Now you can mount it elsewhere for a backup, new disk, etc. If you wish you can also join it back to the original disk, but from your question this is not what you require.
