Module: CISCO-SCSI-MIB
OID (symbolic): CISCO-SCSI-MIB::ciscoScsiLuDefaultLun
OID (numeric): 1.3.6.1.4.1.9.10.95.1.5.1.1.2
Node type: OBJECT-TYPE

Access: read-only
Description: The default Logical Unit Number (LUN) for this logical unit; it is the LUN that will appear to an initiator that was not configured to see another LUN. Note that this object will have a zero-length string if this Logical Unit does not have a default LUN.
What is ciscoScsiLuDefaultLun?
This object is the LUN number this logical unit presents to any initiator that has not been configured to see a different LUN mapping, returned as an empty string if the LU has no default LUN at all. This is the fallback address a newly attached, unmapped host sees for this LU, so getting it wrong risks a new server booting from, or writing to, the wrong disk. For example, a value of 0 means any initiator without explicit LUN masking rules sees this logical unit as LUN 0, the slot most operating systems scan first when looking for a boot disk.
