ciscoExtScsiLunDiscSpinLock
Module: CISCO-EXT-SCSI-MIB
OID (symbolic): CISCO-EXT-SCSI-MIB::ciscoExtScsiLunDiscSpinLock
OID (numeric): 1.3.6.1.4.1.9.9.299.1.1.2
Node type: OBJECT-TYPE
Type: TestAndIncr
Access: read-write
Description: This object is used to facilitate triggerring the LUN/target discovery by multiple managers.
The procedure for triggering LUN/target discovery is as follows:
1. Retrieve the value of ciscoExtScsiLunDiscSpinLock and determine the value for ciscoExtScsiStartLunDisc, ciscoExtScsiLunDiscOs, ciscoExtScsiLunDiscVsanID, ciscoExtScsiLunDiscPortId and ciscoExtScsiDiscType objects.
2. Set the value of ciscoExtScsiLunDiscSpinLock to the retrieved value, and in the same PDU, the value of ciscoExtScsiLunDiscOs to the determined value. If the set fails for the ciscoExtScsiLunDiscSpinLock object, go back to step 1.
3. Set the value of ciscoExtScsiLunDiscSpinLock to the retrieved value plus 1, and in the same PDU, the value of ciscoExtScsiLunDiscVsanID to the determined value. If the set fails for the ciscoExtScsiLunDiscSpinLock object, go back to step 1.
4. Set the value of ciscoExtScsiLunDiscSpinLock to the retrieved value plus 2, and in the same PDU, the value of ciscoExtScsiLunDiscPortId to the determined value. If the set fails for the ciscoExtScsiLunDiscSpinLock object, go back to step 1.
5. Set the value of ciscoExtScsiLunDiscSpinLock to the retrieved value plus 3, and in the same PDU, the value of ciscoExtScsiDiscType to the determined value. If the set fails for the ciscoExtScsiLunDiscSpinLock object, go back to step 1.
6. Set the value of ciscoExtScsiLunDiscSpinLock to the retrieved value plus 4, and in the same PDU, the value of ciscoExtScsiStartLunDisc to the determined value. If the set fails for the ciscoExtScsiLunDiscSpinLock object, go back to step 1.
Note that if it is possible to include ciscoExtScsiLunDiscVsanID, ciscoExtScsiLunDiscPortId, ciscoExtScsiDiscType and/or ciscoExtScsiStartLunDisc in the (Set Request) PDU of an earlier step, then steps 3, 4 and/or 5 can be eliminated.
What is ciscoExtScsiLunDiscSpinLock?
A writable spin-lock object used to coordinate and trigger LUN/target discovery when multiple SNMP managers attempt to initiate discovery concurrently.
