Conﬁguring EMS HA-ATM for ELAN Interfaces

When SAM creates an ELAN on a secondary adapter, it always uses the

same secondary ELAN interface allocation conventions. For example, if

you have three primary ELAN interfaces (ela0, ela1, and ela2)

conﬁgured on primary adapter atm0, the secondary interfaces on

secondary adapter atm1 will be allocated as follows:

• HP-UX 10.20:

• HP-UX 11.X:

NOTE If you have no secondary adapters and ELAN interfaces, but still want to

use EMS HA-ATM to monitor the status of the primary interface (for

example, so that EMS will notify MC/ServiceGuard if a failure occurs),

that is possible: do steps 1 through 6 below, and then select the OK

button.

To conﬁgure HA in SAM, follow these steps:
