HP OneView 1.05 User Guide

What to do when an appliance restarts
The online help provides information about using the user interface or the REST APIs to:
• Check for critical alerts or failed tasks and follow the provided resolution instructions
• Manually refresh a resource if the resource information displayed appears to be incorrect or
inconsistent
• Create a support dump (recommended for unexpected crashes to help support personnel to
troubleshoot a problem)
• Update firmware for a resource, if a firmware update task was in progress when the appliance
shut down.
25.3 Managing the appliance settings
Appliance settings include the network settings, the clock settings, and the SNMP settings for your
appliance in the data center.
If the appliance has not yet been configured when you log in, you are instructed to configure the
appliance network. You can change appliance network settings at any time after they are
configured.
You manage the appliance network configuration from the Settings screen or by using the REST
APIs. The Settings screen enables you to manage various system-wide settings and tasks. Use the
Settings→Actions menu to access various appliance and security tasks, including downloading
audit logs.

25.3.2 Tasks for appliance settings
The appliance online help provides information about using the UI or the REST APIs to:
• Change the appliance host name, IP address, subnet or CIDR mask, or gateway address.
• Change the DNS server IP address.
• Set and synchronize the appliance clock.
• Set the SNMP read community string and add SNMP trap destinations.
25.3.3 About appliance SNMP settings
Network management systems use SNMP (Simple Network Management Protocol) to monitor
network-attached devices. The appliance uses SNMP to retrieve information from managed devices.
The devices use SNMP to send asynchronous notifications (called traps) to the appliance.
You specify a read community string that serves as a credential to verify access to the SNMP data
on the managed devices. The appliance sends the read community string to enclosures (through
their OAs) and to the servers (though their iLO management processors). Some older devices
require manual host OS configuration.
