We have a couple windows cluster currently residing on AMS2500 and would like to do a live migration over to the VSP. Could someone tell me what method can be use to do this?
Hello Calvin Do
How much downtime can you afford to;
Is it VSP or VSP G1000
What are the Mounts (DATA or Boot)?
Is there a connectivity between VSPXXX and AMS?
Its a VSP and I have about 3 hrs downtime. All it is are SQL databases attached to host via mountpoints. Currently I have 2 ports from AMS direct connect to VSP. Can also move those ports to san fabric if needed.
thanks for responding!
You need to perform the following steps:
1. Create Host Groups with the WWN of the servers on the VSP.
2. Shutdown the servers.
3. Remove the LUNs from Host Group in AMS and assign to VSP hostgroup. Delete the old server host group on AMS and zoning in the switch so that the server cannot see previous connections.
4. Discover the LUNs in the VSP and assign it in the same host lun number order as in the AMS.
5. Switch on the server.
Fist, you need to download last PDL for VSP and found pdf docimentation, that is related to External Storage (key words - External Storage, Universal Volume Mnagare, UVM), Volume Migration and Hitachi Storage Tiered Manager.
Your actions will be lokks like:
- shutdown your cluster
- virtualize AMS Lun through VSP and map this virtualized volume from VSP to your hosts. Also you need to shure , your system will recognoze the same Luns but with other ProdustID,VendorID and Serial Number/Lun WWN
- migrate data online by Hitachi Storage Tiered Manager using Volume Migration
Of cource, it is desirable to execute test before real works to estmate real downtime you need to activity, and also you will need to generate temporary or emergency license for Hitachi Tiered Storage Manager and Volume Migration V2 because begining from USP V you need HCS to use Volume Migration.
