This section provides instructions for attaching a storage unit to a Sun host using Sun Cluster.
See the Sun Web site at http://www.sun.com for up-to-date documentation.
Due to a problem found in two-node SunCluster implementations on a storage unit, the following restriction must be observed. When setting up a two-node SunCluster 3.x environment with MPxIO for multipathing, it is mandatory that 1:1 zoning be used; that is, each HBA must be in a zone that contains only 1 HBA and only 1 storage unit target adapter. To ensure that this relationship is maintained, create host nickname definitions using the GUI to enforce "port masking" that allows the host WWPN to login only to the desired storage unit target adapter.
Host "Sun1" with 2 HBAs: "qlc0" and "qlc1"
Host "Sun2" with 2 HBAs: "qlc0" and "qlc1"
DS6000™ with 4 Target adapters:
B1-C1 (cpsspc400)
B2-C1 (cpsspc600)
B3-C1 (cpsspc500)
B4-C1 (cpsspc700)
Sun1:qlc0 -- B1-C1 Sun1:qlc1 -- B4-C1 Sun2:qlc0 -- B2-C1 Sun2:qlc1 -- B3-C1Note that this configuration uses only two target adapters, but each is paired with the HBAs in separate zones, which satisfies the requirement that each initiator be in a zone with itself and only 1 target.
zone 1: Sun1:qlc0 -- B1-C1 zone 2: Sun1:qlc1 -- B4-C1 zone 3: Sun2:qlc0 -- B2-C1 zone 4: Sun2:qlc1 -- B3-C1
This restriction is unique to two-node SunCluster 3.x. with MPxIO. The use of MPxIO is limited to Sun-branded host adapters, thus the restriction does not apply to other adapter brands (AMCC, Emulex, QLogic).
