Troubleshooting EMS HA over ATM
Chapter 9272
If an ATM adapter fails, all of the IP addresses for ELAN interfaces
configured on that ATM adapter must be transferred locally to secondary
ELAN interfaces on a secondary ATM adapter (see Figure 9-16 below).
Figure 9-16 Transferring ELAN Interfaces Locally
Check the log files to confirm that each ELAN interface on the failed
ATM adapter is successfully transferred to the secondary ATM adapter.
For an ELAN interface, this is shown by the message Local recovery
made, showing the primary ELAN interface name and the name of the
secondary ELAN interface name the recovery was made to.
Example for HP-UX 10.20:
03:02:1997:13:41:32:19 307 : Local recovery made
From : ela0 on ATM Card : atm0
To : elc0 on ATM Card : atm2
If local recovery for any interface is not possible, the message Local
recovery not possible appears for that interface.
