Interoperability with legacy FCR switches The following interoperability considerations apply when administering legacy FCR switches in the same backbone (BB) fabric as switches supporting Fabric OS v5.2.x: • When a legacy switch is connected to the fabric, a RAS log message is issued indicating that the capability of the backbone (BB) fabric is lower as legacy FCR switches (those with XPath OS and Fabric OS v5.1) support lower capability limits. • If an XPath OS switch joins the BB fabric, a RAS log message is issued indicating that the backbone-to-edge (B2E) fabric is not supported with the XPath OS switch. For the exact RAS log message descriptions, see the following RAS logs: FCR_1055, FCR_1056, and FCR_1073. Backward compatibility In a fabric with Secure Fabric OS enabled, the edge fabric must have Fabric OS v3.2, v4.4.0, or later because only DH-CHAP authentication is supported. For a nonsecure fabric, the hardware and firmware compatibility is described in Table 51. Table 51 Hardware and firmware compatibility for nonsecure fabrics HP StorageWorks model 1 Gb switches SAN Switch 2/8EL, SAN Switch 2/16EL, SAN Switch 2/16 Supported version Fabric OS v2.6.1 or later Fabric OS v3.1.0 or later SAN Switch 2/32, Core Switch 2/64 Fabric OS v4.1.0x or later SAN Switch 2/8V, SAN Switch 2/16V, SAN Director 2/128 Fabric OS v4.2.0x or later SAN Switch 4/32 4/8 and 4/16 SAN Switch, 4/256 SAN Director 4/64 SAN Switch, 400 MP Router Fabric OS v4.4.0 or later Fabric OS v5.0.1 or later Fabric OS v5.1.0 or later 4/256 SAN Director with FC4-48 or Fabric OS v5.2.x or later FC4-16IP blades NOTE: At the time of this document's release, HP does not support the FC4-16IP iSCSI blade or Brocade 5000 switch.
