Map storage

Before you migrate storage, record the hosts and their WWPNs or IQNs for each volume that is being migrated, and the SCSI LUN when mapped to this system. To use Fibre Channel connections, the system must have installed the optional Fibre Channel host interface adapter.

Record the information in Table 1.

Table 1. Example table.

Volume name or ID	Hosts accessing this LUN	Host WWPNs or IQNs	SCSI LUN when mapped
1 DB2 logs	DB2server	12:...	0
2 DB2 data	DB2server	12:...	1
3 file system	FS1	12:...	2

If partitioned, unmap volumes that are being migrated, and map them to the created host.

The act of mapping a volume to a host makes the volume accessible to the WWPNs or IQNs that are configured in the host object. When you map a volume to a host, you can optionally specify a SCSI ID for the volume. This ID controls the sequence in which the volumes are presented to the host. Check the host software requirements for SCSI IDs because some require a contiguous set. The lowest available SCSI ID is automatically assigned if none is specified.
