Configure Array-Side Networking - Lenovo ThinkSystem DE Series Hardware Installation And Maintenance Manual

If you are using jumbo frames within the IP SAN for performance reasons, make sure to configure the array,
switches, and hosts to use jumbo frames. Consult your operating system and switch documentation for
information on how to enable jumbo frames on the hosts and on the switches. To enable jumbo frames on
the array, complete the steps in Configuring array-side networking—iSCSI.
Note: Many network switches have to be configured above 9,000 bytes for IP overhead. Consult your switch
documentation for more information.

Configure array-side networking

You use the ThinkSystem Storage Manager GUI to configure iSCSI networking on the array side.
Before you begin
• You must know the IP address or domain name for one of the storage array controllers.
• You or your system administrator must have set up a password for the System Manager GUI, or you must
configured Role-Based Access Control (RBAC) or LDAP and a directory service for the appropriate
security access to the storage array. See the ThinkSystem System Manager online help for more
information about Access Management.
This task describes how to access the iSCSI port configuration from the Hardware page. You can also
access the configuration from System > Settings > Configure iSCSI ports.
From your browser, enter the following URL: https://<DomainNameOrIPAddress>
Step 1.
I I P P A A d d d d r r e e s s s s is the address for one of the storage array controllers.
The first time ThinkSystem System Manager is opened on an array that has not been configured,
the S S e e t t A A d d m m i i n n i i s s t t r r a a t t o o r r P P a a s s s s w w o o r r d d prompt appears. Role-based access management configures
four local roles: admin, support, security, and monitor. The latter three roles have random
passwords that cannot be guessed. After you set a password for the admin role, you can change
all of the passwords using the admin credentials. See ThinkSystem System Manager online help for
more information on the four local user roles.
Step 2. Enter the System Manager password for the admin role in the S S e e t t A A d d m m i i n n i i s s t t r r a a t t o o r r P P a a s s s s w w o o r r d d and
C C o o n n f f i i r r m m P P a a s s s s w w o o r r d d fields, then select the Set Password button. Log out, then log back in to
System Manager with the admin credentials.
When you open System Manager and no pools, volumes groups, workloads, or notifications have
been configured, the Setup wizard launches.
Step 3. Close the Setup wizard.You will use the wizard later to complete additional setup tasks.
Step 4. Select Hardware.
Step 5. If the graphic shows the drives, click Show back of shelf.
The graphic changes to show the controllers instead of the drives.
Step 6. Click the controller with the iSCSI ports you want to configure.
The controller's context menu appears.
Step 7. Select Configure iSCSI ports.
The Configure iSCSI Ports dialog box opens.
Step 8. In the drop-down list, select the port you want to configure, and then click Next.
Step 9. Select the configuration port settings, and then click Next.To see all port settings, click the Show
more port settings link on the right of the dialog box.
