Some time ago I needed to check topology of a client’s Exadata due a network issue and made a very useful note. Sharing with you now. 😀
This and other cool commands can be found here: Network Diagnostics information for Oracle Database Machine Environments (Doc ID 1053498.1)
# /opt/oracle.SupportTools/ibdiagtools/verify-topology -t quarterrack
Newer versions don’t require -t option.
In case of halfrack, -t halfrack should be used in my case.
Ok, but how to know it? You can have it from here:
[root@greporaexa onecommand]# grep -i MACHINETYPES databasemachine.xml [MACHINETYPES]X4-2 Eighth Rack HC 4TB[/MACHINETYPES]
Hope it helps! 🙂
