scsiLuDefaultLun
Module: SCSI-MIB
OID (symbolic): SCSI-MIB::scsiLuDefaultLun
OID (numeric): 1.3.6.1.2.1.139.2.4.1.1.2
Node type: OBJECT-TYPE
Type: ScsiLUN
Access: read-only
Description: This object represents the default Logical Unit Number (LUN) for this logical unit; if a SCSI initiator device has not been configured to view this logical unit via an entry in the ScsiLunMapTable, the LU will be visible as scsiLuDefaultLun. If this logical unit does not have a default LUN, it will only be visible if specified via the ScsiLunMapTable, and this object will contain a zero-length string.
What is scsiLuDefaultLun?
The LUN this logical unit appears as by default to any initiator that hasn't been given a custom mapping via scsiLunMapTable; if there's no default LUN, this is an empty string and the LU is only visible through explicit mapping. Admins rely on this to know what LUN number a host will see 'out of the box' versus needing a LUN-map entry.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.139.2.4.1.1.2 snmpwalk -v2c -c public <target> SCSI-MIB::scsiLuDefaultLun
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.139.2.4.1.1.2.1 snmpget -v2c -c public <target> SCSI-MIB::scsiLuDefaultLun.1
