zoneCopyActToFullSpinLock
Module: CISCO-ZS-MIB
OID (symbolic): CISCO-ZS-MIB::zoneCopyActToFullSpinLock
OID (numeric): 1.3.6.1.4.1.9.9.294.1.1.42
Node type: OBJECT-TYPE
Type: TestAndIncr
Access: read-write
Description: This object is used to facilitate modification of zoneCopyActToFullMode and zoneCopyActToFullOnVsan by multiple managers. The procedure for modifying these objects is as follows:
1. Determine new values for zoneCopyActToFullMode, zoneCopyActToFullOnVsan.
2. Retrieve the value of zoneCopyActToFullSpinLock.
3. Set the value of zoneCopyActToFullSpinLock to the retrieved value, and (in the same PDU) the value of zoneCopyActToFullMode to the new value. If the set fails for zoneCopyActToFullSpinLock, go back to step 2.
4. Set the value of zoneCopyActToFullSpinLock to the retrieved value plus one, and (in the same PDU) the value of zoneCopyActToFullOnVsan to the new value. If the set fails for zoneCopyActToFullSpinLock object, go back to step 2.
Note that if it's possible to include zoneCopyActToFullOnVsan in the (Set Req) PDU of the earlier step, then step 4 can be eliminated.
What is zoneCopyActToFullSpinLock?
This read-write TestAndIncr object coordinates safe concurrent modification of zoneCopyActToFullMode and zoneCopyActToFullOnVsan when multiple SNMP managers might change them at once: a manager reads the current lock value, then sets it back along with the new configuration values in the same PDU, so a stale read causes the whole set to fail. It protects against two admins simultaneously configuring conflicting active-to-full zone set copy settings. For example, if two SAN management consoles both try to reconfigure the copy-to-full behavior for the same VSAN at once, this spin lock ensures only the manager with the current value's set actually takes effect.
