To investigate why an Exadata Database Server stopped communicating on the client network for 10 minutes over the past weekend, you can use the GetExaWatcherResults.sh script to collect and analyze ExaWatcher data for a specified time range1.

Therefore, the command that you should use to investigate this is:

• /opt/oracle.ExaWatcher/GetExaWatcherResults.sh —from _17:00:00 —to _23:59:00

The CELLCLI CALIBRATE command can be used to check the health of all flash cards in the storage server, and it should be run after logging in as the celladmin user. The hardware monitoring using the storage server ILOM should also be used to check for errors and other potential issues with the flash cards. The CELLCLI list LUN DETAIL command should not be used to identify a damaged or failing flash card, since it will not provide any information about the health of the flash card.

According to Oracle’s documentation1, the client network on Exadata X9M-2 Database Server is used for client access to the database servers using Single Client Access Name (SCAN) and Oracle RAC Virtual IP (VIP) addresses. To verify that the client network is available via both client switches, you can use the command:

• cat /proc/net/bonding/bondeth0

This command displays information about the bondeth0 interface, which is used for the client network on Exadata X9M-2 Database Server2. You can check if both interfaces (eth0 and eth1) are active and connected to different switches3.
