Steps to follow migrating storage from IBM DS8000 to IBM SVC in image mode Step 1: Identify the controller (IBM DS8000 series) that is to be migrated to the IBM SVC

Step 2: Check and make sure that IBM DS8000 and IBM SVC are plugged into same SAN fabrics

Step 3: Make sure that the IBM DS8000 plugged into both SAN fabrics

Step 4: Create zoning between IBM DS8000 and the IBM SVC.

Step 5: Make sure that every SVC node port zoned with DS HA port.

Step 6: Please note that the maximum number of DS HA ports that can be zoned with IBM SVC are 16.

Step 7: Define IBM SVC as a host on the DS 8000. Make sure that all IBM SVC node ports are defined

on the IBM DS.

Step 8: Create and add all SVC host connections to one volume group.

Step 9: Identify the hosts that are to be migrated.

Step10: Collect the output of “datapath query device”, “datapath query adapter”, “datapath query

wwpn” and “datapath query version”

Step11: Check for the compatibility of multipathing (IBM SDD) driver version

http://www-01.ibm.com/support/docview.wss?uid=ssg1S1004111

Step12: Stop the application on the server

Step13: Unmap the IBM DS 8000 LUN’s on the server.

Step14: Disable the ports of the server on the SAN fabrics.

Step15: Remove the zoning between the host and the IBM DS 8000

Step16: Create the zoning between the host and the IBM SVC

Step17: If the version of drivers is not in compatible level, install / upgrade compatible drivers.

Step18: Unmap the LUN’s from host volume group on the IBM DS 8000

Step19: Map the LUN’s that is unmapped from host volume group to the IBM SVC volume group

Step20: On the IBM SVC detect the LUN’s as mdisks by running “svctask detectmdisk” command

Step21: Create a temporary mdisk group on the SVC

Note: Please do not add mdisks to mdisk group. To create image mode vdisks, mdisks must be in

unmanaged mode

Step22: Create image mode vdisk out of unmanaged mode mdisk and add to the temporary mdisk group.

IBM_2145:SVC:admin>

Step23: Create logical host definition on the IBM SVC


Step24: Map the image mode virtual disk to the host

Note: While mapping vdisks to host please use “-scsi” parameter, use the same scsi ID

Step25: Contact the system administrator to get the update about the multipating

Step26: Enable the SAN ports on the fabrics

Step27: Contact the system administrator to rescan the disks and to perform relevant health checks on the server

Step28: After performing health checks, ask the system administrator to start the application / Data base

Step29: Collect the information about ‘datapath query device”

C:\Program Files\IBM\Subsystem Device Driver>datapath query device -l

Step30: Migrate the image mode vdisks to striped mode on the IBM SVC

Step31: After successful migration from image mode to striped, remove the mdisks from mdisk group on

the SVC and delete the temporary mdisk group

Step32: Unmap the vdisks on IBM DS8000 from the SVC volume group

Step33: Follow the GTS process to ensure a 48 hour waiting period before deleting the LUN’s on the DS8000.

Step22: Create logical host definition on the IBM SVC

Step23: Map the image mode virtual disk to the host

Note: While mapping vdisks to host please use “-scsi” parameter, use the same scsi ID

Step24: Contact the system administrator to get the update about the multipating

Step25: Enable the SAN ports on the fabrics

Step26: Contact the system administrator to power on the server

Step27: After performing health checks, ask the system administrator to start the application / Data base

Step28: Collect the information about ‘datapath query device”
