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
You control this remote service. IBM recommends that you enable this service by
checking Yes. When you enable outgoing-modem calls, the ESS places the
call-back password in the header of each call home record. The call-back
password allows your service provider to login to the ESS in response to the
service call.
v
Enable remote login
You control this remote access. IBM recommends that you enable this service by
checking Yes. Service personnel can login to the ESS with the call-back
password.
v
Optional remote access password
This password adds further security to the support login ID. This password
should be set in agreement between you and IBM service personnel.
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:
