Zoning

Introduction
Zoning
This section contains general configuration guidelines when
connecting a Linux server via Fibre Channel or iSCSI to an EMC
storage array.
Note: Multi-initiator zones are not recommended in a Linux fabric
environment.
FC and FCoE
When using Linux hosts in a fabric environment, the zoning must be
set up as single initiator and single target zoning. A single
initiator/single target zone is composed of one adapter and one EMC
storage array port. Storage array ports can be shared among adapters;
however, each adapter must be in its own zone.
Note: Multi-initiator zones are not recommended in a Linux fabric
environment.
iSCSI
Follow the guidelines outlined by EMC. Be aware that using
improper settings may cause erratic behavior. In particular, note the
following:
◆ Each QLogic iSCSI HBA in a Linux server must be on a separate
subnet.
◆ A single host can not mix HBAs and NICs to connect to the same
array or different arrays.
◆ A single host may not attach to an EMC Fibre Channel Array and
an EMC iSCSI Array simultaneously.
◆ QLogic SANsurfer or iscli are required to be installed in order to
configure iSCSI HBAs to connect to iSCSI targets
