Re: EVA 8100 adding new disk
Once you have all the disks inserted into the enclosures...
1. add all the disks to the existing disk group.
2. Wait for the leveling to complete. (This wil spread out all the data to ALL of the disks in the group)
3. Remove the 146GB disks, one at a time from the disk group.
4. Reuse the 146GB disks for something else.
5. Go home happy cause you saved yourself a lot of time.
6. Make sure you back up your data first.

Re: EVA 8100 adding new disk
are your Vdisks RAID5, do you want to convert these to VR1?
if so you have two optons, obtain a temp BC licence if CU dont have, and after adding the 300GB drives (to the same or new group, makes no sense at that point, new group may be easier) shutdown the Database, create a snapclone with new raid level you want, after snapcloneing started, unpresent all VR5 drives and present new VR1 drives with exactly same LUN numbers,
you can need some operations on the os side also, to tell the os that disks are changed, but data didnot.
after the disk cloneing has finished you can split the clone and delete the VR5 ones, at that point you can delete the 146 GB if you did not create new DG, and when deletion finished, you can create a new DG with 146GB drives for application or what

Re: EVA 8100 adding new disk
it can be done within the OS side.
you create new DG with 300GB drives and VR1 LUNs as of CU request, then present them to the hosts, at that point OS of your host is the question. if it is HPUX, then you can extend the Volume Groups with new disks, move all the data to the new disks with simple pvmove command and reduce the old disks and unpresent them. if not HPUX, say windows then you need to copy them or backup and restore.

Re: EVA 8100 adding new disk
Go back to your customer and ask them why they want to have the 16 new drives in a new disk group.
If the customer is talking about RAID 1+0 then they probably don't understand how the EVA works.
You don't mention the existing configuration, however as it's an EVA8100 I'll assume that the Disk Group with the 146GB disks has more than 16 disks. If so, then moving to a group with only 16 disks could actually reduce performance...

Rob

Re: EVA 8100 adding new disk
thanks all.
right now the have two disk group. one they r using for backup copy another one for DB and application.
now they want to make another diskgroup separate db from application means new diskgroup for application.
then they will copy all data from existing diskgroup to new diskgroup ( DB and APP) for test.
os is HP-UX 11iv1.so i have to create mount point for nw disk group.
if ok .then they will separate db and app.
this is cluster environment.
now advice.
