Solution 1333899.1 : VSM - Bi-directional Cluster Clink Hardware Configuration

Applies to:

Sun StorageTek VSM System - Version 5 to 5C [Release 5.0]
Information in this document applies to any platform.

Goal

How are out-bound and in-bound CLINKS of each VSM configured in compliance with bi-directional clustering?

Solution

Configure the in-bound clinks to the interfaces of one cluster, and the out-bound clinks to the interfaces of the other cluster within the same VSM. In-bound and out-bound clinks must NOT be configured to the same cluster in the same VSM. The consequence of non-compliant configuration can be replicate, channel, and communication errors.

Information notes:

1. A VTSS cluster is different than a VTCS Clustered environment.
    A VTSS hardware cluster is made up of one half of the functional hardware.
    Control Regions 0/1 and VCF/ICE 00-03 are in cluster 0.
    Control Regions 2/3 and VCF/ICE 10-13 are in cluster 1.
    A VTCS Cluster configuration processes data in one VTSS, then
    replicates the data to a second VTSS.
2. Bi-directional Cluster configurations are set up between two VTSS. Each VTSS has the ability to send and receive replicated data to/from the other VTSS.
    The problem stated does NOT apply to Uni-direction Cluster configurations.
