Dell EMC VxFlex Ready Node, User Manual

General
SNMP traps are implemented as part of VxFlex OS, using SNMP v2. UDP transport is
used for SNMP, and the default port for trap communication is 162. The SNMP
feature is enabled by default.
The SNMP trap sender includes a proprietary/custom
MIB
called
scaleio.mib
. This
MIB
file is located on the VxFlex OS gateway server, in the
/gateway/webapps/
ROOT/WEB-INF/classes
folder. A copy of the
MIB
file is included in at the end of
this section. A general trap type with a unique identification number (OID) is defined in
the
MIB
, so that the SNMP traps are configured to contain alert data within
themselves, and use a single OID (as opposed to granular traps). All the SNMP traps
contain variable bindings for severity type, which is the alert classification; the ID of
the source object for which the alert was created; and an action code, which is the
event number.
Only TRAP commands/messages are supported, and are initiated by the VxFlex OS
SNMP traps manager. GET/SET operations are not supported (or more specifically,
GET/GET NEXT/GET BULK/SET/INFORM/RESPONSE).
In addition to SNMP traps, alert messages are also displayed in the VxFlex OS GUI.
Supported alerts and event numbering conventions
The following alerts can be sent as SNMP traps by VxFlex OS. All events are
numbered in the following format: SIO<CLASS>.<TYPE>.<ISSUE>. The issue number
is a running counter for all issues in a specific type.
Open and closing alerts will consist of the same code and issue number, with the
exception of the first digit (0 or 1) in the <ISSUE> section. For example:
l
SIOXX.XX.0XXXXXX indicates that the alert is active
l
SIOXX.XX.1XXXXXX indicates that the alert has been closed
CLASS/TYPE:
System = 1
l
Capacity = 1
l
License = 2
MDM = 2
l
MDM_Cluster = 1
l
Protection_Domain = 2
l
Fault_Set = 3
l
Storage_Pool = 4
SDS = 3
l
SDS = 1
l
Device = 2
SDC = 4

SDC = 1
