On Superdome
Systems
For Superdome systems all iCOD partitions must be configured to send
e-mail to HP. This is because each iCOD partition reports the processor
information for itself. It is recommended that the e-mail capability be
configured and the iCOD software be installed on the non-iCOD
partitions, as well. This makes it easier for you to later redistribute
processors across partitions (that is, load balance). See “Load-balancing
Active Processors” on page 61 for details.
E-Mail Configuration
Before you Start
Your iCOD system must be network accessible to HP mail servers that
are outside your company's firewalls. If your iCOD system is on an
isolated network, e-mail from the iCOD system does not reach HP. This
causes your iCOD system to be out of compliance with HP’s On Demand
Solutions program.
Sendmail
sendmail is the application used by the iCOD software to send encrypted
mail messages from your system to HP. The sendmail daemon, if
running, can also be used to receive e-mail. For the purposes of this
e-mail configuration, only the ability to send e-mail is required.
Mail applications invoke sendmail to send e-mail. The configuration file,
/etc/mail/sendmail.cf, offers tremendous flexibility.
