You'll have to virtualize the USP-V behind the VSP. Here's a basic summary of the process.
1) If the DP volumes are mapped to hosts, un-map them.
2) Configure 2 External ports on the VSP
3) Zone 2 USP-V Target ports to 2 VSP External ports
4) Map DP volumes from USP-V to VSP
5) On VSP, virtualize the volumes
6) Use Tiered Storage Manager to migrate virtualized volumes to internal storage
I recommend requesting assistance from HDS if you aren't familiar with the process.
Hi Dang Luong
First I would like to thank you for the valuable answer.
I am just a beginner in hitachi , so I dont have much information about migration.
I have few doubts regarding the steps you mentioned.
1. Step 2 - choosing external port in VSP means the port which is not used ?
2 . Step 3 - Can you elaborate it more.
3 . Step 5- how to virtualize volumes.
I'll try to clarify the points.
Dang: "External" is a port type. It is only used for virtualization. The other port types are Target, MCU, and RCU. Target ports are used to present volumes to servers. MCU & RCU are used for array replication.
Dang: from the USP-V's perspective, the VSP is just another host. I'm assuming your storage arrays and hosts are connected to FC switches. In order for the USP-V and VSP to see each other, their ports must be zoned together. I typically create 2 zones: Zone A with USP-V Target Port 1 to VSP External Port 1 and Zone B with USP-V Target Port 2 to VSP External Port 2.
Dang: once the USP-V volumes have been presented to the VSP, the VSP now has to discover them. This is typically done in Storage Navigator. I recommend going through the manual Universal Volume Manager which the virtualization process in details.
Regarding Step 3 :-
I am giving you the senario of my environment. We are doing wwn zoning based by following the naming convention as :-
Say the server needs to zoned to VSP we are naming it mssj190_TOM-VSP1-CPU2_CL5A ( TOM is Tomteboda name of location where VSP is kept in Sweden and mssj190 be the server name).
My point is that you mentioned USP and VSP ports must be zoned together , this means that I should add one port of VSP and one port of USP for the server together ? May be you are saying me to map the particular server from both USP target port and VSP external port.
Its little confusing for me to understand how to zone target port of USP and external port of VSP together.
When the VSP port is configured to be an External port, it becomes like an initiator port (similar to FC ports from a regular server).
If you want I can share a document, send me ur email id , which I used for USP-V virtualization with AMS , maybe you would understand the process looking at the screenshots. This is the step 5 in Dang's reply.
From what I understood, The step 3 in Dang Luong is basically creating the path between two Storage Arrays just like you do for replication ports between the two Arrays for TC data flow. But in this path creation, the USP-V acts like a windows host for the VSP when you zone them and create the external paths. Through these paths , the data flows to & from VSP & USP-V.
I hope I didn't complicate it for you
My mail id is email@example.com, Could you please sennd me the document.
This is Velu,
Could you please share that same document to me also.Please
Email id : firstname.lastname@example.org
I am planning to do migration from heterogeneous storage to Hitachi VSP.
Could you please share me procedure manual documents .
Can you send me that document on email@example.com.
Wish to receive some more information from your side.
You can zone something similar to this.
Where Z_REP=Replicaton zone ( you can use a different naming here)
MUNBROREP01/02 are switch name, this can be your VSP and USPV
Create alias beforehand for each VSP and USPV ports to zone such as
MUNHUSVM_23XXXX_CL1A =Systemname + serial number +portname
This will zone one Target ( USPV)+one externamal ( VSP) to suite your implementation.
Please modify the naming to suite your enviroment.
Hope that help
Can you pls share that migration document, my email id firstname.lastname@example.org
Thanks for your help.
