cucsVnicBootTargetLun
Module: CISCO-UNIFIED-COMPUTING-VNIC-MIB
OID (symbolic): CISCO-UNIFIED-COMPUTING-VNIC-MIB::cucsVnicBootTargetLun
OID (numeric): 1.3.6.1.4.1.9.9.719.1.53.1.1.4
Node type: OBJECT-TYPE
Type: SnmpAdminString
Access: read-only
Description: Cisco UCS vnic:BootTarget:lun managed object property
What is cucsVnicBootTargetLun?
This read-only SnmpAdminString value holds the Logical Unit Number (LUN) this Boot Target entry points a vHBA to boot from. The LUN number, combined with the target WWN, is exactly what the server's boot firmware needs to locate the correct boot volume on the SAN, so a wrong LUN value here directly explains a 'no boot device found' failure. For a Boot Target pointing a server's vHBA at LUN 0 on storage-array WWN 20:00:00:25:b5:00:00:0a, this OID returning LUN 0 confirms the server's boot policy is set to boot from LUN 0 on that storage array, which an admin would cross-check against the actual LUN masking on the array.
