If you will be using Global Link Services (GLS), use the GLS Setup Worksheet to organize the input items beforehand.
This section describes the worksheet settings for the following typical duplexing modes:
NIC switching mode (virtual IP takeover)
NIC switching mode (physical IP takeover I)
NIC switching mode (physical IP takeover II)
Fast switching mode
GS linkage mode
See
For configuration instructions for other duplexing modes, see "Appendix B Examples of configuring system environments" in the "PRIMECLUSTER Global Link Services Configuration and Administration Guide : Redundant Line Control Function."
For information on the items in this sheet, see the explanation at the bottom of the sheet and "6.2 Initial GLS Setup." Also see "A.11.1.3 GLS Setup Worksheet" in "A.11 System Design Examples (for the Virtual Machine Function not used)."
