5–Performing Data Migration
Presenting LUNs to the Server for Online Data Migration
ISR654608-00 B 5-5
To present source and destination LUNs from iSCSI arrays:
1. Determine the iSCSI initiator name of each blade by issuing the
show
iscsi
command; see page 6-59 .
2. Using an array management utility, register the router as a host using the
iSCSI qualified name (IQN) of the iSCSI port, and then assign LUNs to this
host.
3. Using the CLI, discover iSCSI storage arrays by issuing the
iscsi
discover
command (see page 6-18 ).
4. List the discovered iSCSI targets, as well any Fibre Channel targets (if
present), by issuing the
show targets
command (see page 6-85 ).
5. Log into the iSCSI target by issuing the
iscsi login
command (see
page 6-19 ).
After successful iSCSI login, the iSCSI target comes online.
6. (Optional) To discover the newly-presented LUNs and form the new arrays,
if required, follow these steps:
a. In the left pane of SANsurfer iSCSI/FC Router Manager, click the
Router tab.
b. Right-click the appropriate blade.
c. On the shortcut menu, click Rescan .
Presenting LUNs to the Server for Online Data
Migration
For online data migration, you need to create access to all LUNs associated with
the server or servers through the router, and you must eliminate direct access
from the server to the storage array.
NOTE:
Some iSCSI arrays require pre-registered hosts for the
iscsi
discover
command to succeed. For these arrays, manually create a
host with the IQN of the router iSCSI port before you issue the
command.
NOTE:
If the iSCSI storage array supports it, you can establish multiple
connections per session using multiple GbE ports on the same router
blade and storage array.
