backup from different storages ..

[v.saravanan_1]

Hi ,
I was paln to upgrade my storage subsystem from RA8000 to EVA8000 , and we have one seperate RA3000 storage for other application. My question is how to take a full data backup from RA8000 to EVA8000 , what are all the precautions i have take before upgrading the storage.Is there any study meterial and tools available for this ?.And one more thing i was not upgrading the RA3000 , is there any way to take a backup from one stoarage (RA3000) to other different storage (EVA8000) through network. Because EVA8000 have more diskspace so i was paln to keep some of the important data to EVA8000.

This very much depends on the OS and Volume Manger you are using.
If for example you have Tru64 with LSM you can install the EVA, configure the LUNs and set up software mirroring to do the task of mirroring the RA to the EVA. Then you can deinstall the RA.

If you want to be on the safe side I would ask HP to do this as a service for you! HP has lots of experience.

YOu can use the cp -r or dd or cpio command , to transfer the data , though it will take quite sometime and depending on the data volume.

Btw , which OS are u using.

Then it is rather easy!
Before connecting the new EVA make sure that you meet the minimum requirements like HBA HW and FW, patch level, switch FW etc.
Use the SAN Design Referece Guide and the respective EVA OS Guide as base. Find them here

After connecting the EVA, create LUNs that match the sizes of the ones on the old storage.

Then use the OS based mirroring function (LSM on Tru64, do not know the name on VMS) and mirror all LUNs.
When all LUNs are in mirror state you can split the old LUNs off and disconnet the old arrays!

If in doubt ask HP for support

Hi Peter ,

Is there any tool available for take the backup from different storage (RA8000 to EVA8000)..

[Peter Mattei]

Yes sure there is.
The HP backup software is called Data Protector and can backup and restore any storage on most operating systems.

Saying that; are you not doing any backups yet?
