Use the Add a New Syslog Server panel in the SAN Volume Controller Console to
add a syslog server to receive notifications for the cluster.
Introduction
The syslog protocol is a client-server
standard for forwarding log messages from a sender to a receiver on
an IP network. The IP network can be either IPv4 or IPv6. The User
Datagram Protocol (UDP) is used to transmit the syslog message. The
syslog protocol can be used across multiple platforms, which enables
you to integrate log data from different types of storage systems
into a central repository. You can use the SAN Volume Controller Console to
configure and modify your syslog settings. SAN Volume Controller can
transmit syslog messages in fully expanded or concise format.
The SAN Volume Controller facility
value is mapped to a corresponding syslog facility code and value.
The facility of a syslog message indicates its origin and can be used
to differentiate messages by source. For example, the facility value
differentiates messages sent from two clusters or messages sent from
a cluster and other products that uses syslog to send messages.
The SAN Volume Controller facility
of 0 - 3 results in the syslog server receiving messages in concise
format, which provide standard detail on the event. A SAN Volume Controller facility
of 4 - 7 results in the syslog server receiving messages in fully
expanded format, where more details are provided regarding the event.
The following table describes the
SAN Volume Controller facility
and its corresponding syslog code and value.

Attributes
The
following attributes are displayed:
- Server Name
- Enter a name for the syslog server. A valid name
is 1 to 15 ASCII characters. The following characters can be used:
a - z, A - Z, 0 - 9, -, _. The name cannot begin with a number or
the hyphen (-) character. Names starting with syslog are
reserved for SAN Volume Controller default
names.
- IP Address
- Select correct protocol and enter a valid IP address for the syslog
server. Both IPv4 and IPv6 address formats are supported.
- IPv4
- Select this option if you are currently using IPv4 address formats,
and then enter a valid address for the syslog server.
- IPv6
- Select this option if you are currently using IPv6 address formats,
and then enter a valid address for the syslog server.
- SVC Facility
- Select the SAN Volume Controller facility
for the syslog server. This value is translated to the corresponding
syslog code and value. The SAN Volume Controller facility
of 0 - 3 results in the syslog server receiving messages in concise
format, which provides standard detail on the event. A SAN Volume Controller facility
of 4 - 7 results in the syslog server receiving message in fully
expanded format, where more details are provided regarding the event.
- Send Error Notifications
- Select this option to send events
with the notification type of error to the syslog server.When an event notification with the
type error is received by the SNMP server, the problem
must be fixed immediately. This notification indicates a serious
problem with the SAN Volume Controller cluster.
For example, the event that is being reported could indicate a loss
of redundancy in the system, and it is possible that another failure
could result in loss of access to data. A hardware failure is the
most typical reason this type of notification is sent, but some configuration
errors or fabric errors also are included in this notification type.
- Send Warning Notifications
- Select this option to send events
with the notification type of warning to the syslog server.A warning notification is sent to
indicate a problem or unexpected condition with the SAN Volume Controller.
Always immediately investigate this type of notification to determine
the effect that it might have on your operation and correct the problem
if necessary. A warning notification does not require any replacement
parts and therefore should not require IBM® Support
Center involvement. However, the event being reported might indicate
a condition that could be fatal to your operating environment; such
as, a critical FlashCopy® operation
has failed.
- Send Informational Notifications
- Select this option to send events
with the notification type of informational to
the syslog server.For these types of notifications,
no action is necessary to resolve them. This notification indicates
an event that was expected has occurred. For example, a FlashCopy mapping event has completed successfully.
No remedial action is required when these notification types are sent.
