Pinned topic V7000 data migration from cluster

‏2014-05-29T18:05:07Z |

Hello

We have a HP P6300 storage where a MS Windows cluster (with SAP) is running. We have a brand new V7000,that we want to use to do some virtualization of some of the LUNs from the P6300 and Data Migration from other set of LUNs

Searching through the redbooks and papers, seems there is a limitation with the Data Migration Wizard, that you can´t used it to migrate clusters

 

Is this a limitation from the wizard ? I mean can I move that data from the cli?

Any experience on this?

 

Thank you

    I can confirm I have used the data migration feature to migrate both physical Windows 2003 and 2008 clusters and virtual machines with MSCS 2003 and 2008R2 clusters running on VMWare with pRDM's with no problems at all.

    As Chris says, its all about the wizard is not "cluster/multi-host" aware.

     

    So as long as you know what you are doing, there is no problems with it.

    I *think* the limitation of the GUI wizard is because clustered host systems will require volumes to be mapped to the multiple hosts with the same SCSI LUN#, and all hosts will need to be migrated at the same time.   I think the expectation is that, because it's a more involved process, the user should go through the stages of procedure using either the GUI or CLI step by step.

    Thank you for your answer Anders, it was very helpful

    Can I ask you for some tips or things I should look before doing this migration? Since this is a productive SAP, disruptiom has to be minimal

    Thank you chris

    Can you point me where to find CLI procedures/commands to do this?
