Chapter 4. Planning for communication
This chapter provides guidelines for completing the Communication Resources work
sheet (see "Guidelines for completing the Communication Resources work sheet")
and the ESS Copy Services work sheet (see "Communications for ESS Web Copy
Services" on page 73).
Communication overview
During installation IBM establishes communication links between the ESS and your
storage management personnel, and between the ESS and service personnel.
IBM installation personnel use the information from the work sheet to establish
communications between your host system and the ESS.
After IBM has installed the ESS, you can change the communication settings from
the Web interface. See the IBM Enterprise Storage Server Web Interface User's
Guide for guidelines on using the IBM StorWatch Enterprise Storage Server
Specialist to change the settings.
The Communication Resources work sheet allows you to define how the various
communications functions within the ESS should be configured. It also lets you
authorize or deny access to your ESS by service personnel. The following
communications functions are available:
v Enable outgoing modem calls
v Enable remote login
v Optional remote access password
With access to the ESS, service personnel can perform service tasks, such as
viewing error logs and problem logs and initiating trace or dump retrievals.
Guidelines for completing the Communication Resources work sheet
Use the following guidelines when completing the work sheet that is shown in
"Appendix A. Communication Resources work sheet" on page 85:
