Configuring the Fujitsu ETERNUS to use with the Lenovo Storage V7000

To use this external storage, you must configure the Fujitsu ETERNUS to enable attachment to Lenovo Storage V7000. It is important that you use the correct settings to avoid data access problems.

Use the following sequence of steps to configure the Fujitsu ETERNUS system:
  1. Configure the Lenovo Storage V7000 host response pattern.
  2. Register the host world wide names (WWNs) and associate them with the host response pattern.
  3. Setup the affinity group for Lenovo Storage V7000 volumes or setup LUN mapping.
  4. Create or reassign storage to the Lenovo Storage V7000.
For all other settings and procedures, consider the Lenovo Storage V7000 a host.
Note: See the documentation provided with the Fujitsu ETERNUS system.

Host response pattern

The Lenovo Storage V7000 requires that a new host response pattern is created. If the Host Affinity/Host Table Settings Mode is used, this host response pattern must be associated with each WWN. If the Host Affinity/Host Table Settings Mode is not used, this host response pattern must be associated with the target port.

Table 3 lists host response patterns for Fujitsu ETERNUS Models DX60 S2, DX80 S2, DX90 S2, DX410 S2 and DX440 S2.

See the documentation that is provided with your Fujitsu ETERNUS system for more information because some options are only available on certain models.

Host WWNs

After the Lenovo Storage V7000 is zoned on the fabric to see the Fujitsu ETERNUS, the system might not initially appear in the list of controllers when you issue the lscontroller CLI command. This is normal and expected behavior.

See the documentation that is provided with the Fujitsu ETERNUS system to add all Lenovo Storage V7000 WWPNs as host WWNs. The following restrictions apply:
  • The Lenovo Storage V7000 WWNs must be associated with a host response pattern. The host response pattern must be defined prior to registration. If you use an incorrect or default host response pattern, you can lose access to data.
  • All Lenovo Storage V7000 WWNs must be registered on all Fujitsu ETERNUS ports on the same fabric. If the WWNs are not registered, you can lose access to data.

Affinity groups/zones

Use the affinity groups/zones mode to protect the Lenovo Storage V7000 LUs if the SAN is incorrectly configured. The affinity group mode is setup in the CA configuration. See the documentation that is provided with your Fujitsu ETERNUS system for more information about using the affinity groups/zones mode. The following restrictions apply:
  • Each Lenovo Storage V7000 must have exactly one affinity group/zone.
  • The Lenovo Storage V7000 affinity group/zone must be associated with all Lenovo Storage V7000 WWNs.

LUN mapping

You can use the LUN mapping mode (also called the zone settings mode for some models) with the following restrictions:
  • The SAN zoning must only allow a single Lenovo Storage V7000 access to this target port.
  • The host response pattern must be set in CA configuration using the required Lenovo Storage V7000 settings.
Note: If you use the LUN mapping mode, you cannot use the host affinity mode. The host affinity mode is set to OFF.

Assigning storage to the Lenovo Storage V7000

Ensure that you understand all Lenovo Storage V7000 and Fujitsu ETERNUS restrictions before you assign storage to the Lenovo Storage V7000. See the documentation that is provided with the Fujitsu ETERNUS system for more information.
