This object provides a quick means of activating a valid zone configuration on all active SAS switches. The zone configuration to be activated is specified as the value of the SET and can be obtained from the switchZoneCfgNumber object. The zone configuration number is also referred to as the zone configuration store. Before activating a new zone configuration, a user must consider the following: 1) Changing the zone configuration may cause disruption in the storage access of blades connected to this SAS Module. It is highly recommended that you first ensure that the blades have completed all storage accesses. You may want to shutdown the blade OS prior to changing your zone configuration. 2) When selecting a zone configuration, ensure that it is appropriate for the number of SAS switches installed in your chassis. This can be determined from the switchZoneCfgDescription text. 3) When selecting a zone configuration, ensure that it exists first on all SAS switches. This can be determined by querying the storageSwitchZoneCfgTable. In addition, for user-defined zone configurations, even if the number is the same, ensure that the actual zone configurations are identical or compatible. You will need to use an application, such as the Switch Configuration Manager (SCM) to verify this. 4) All SAS switches must be in operational state prior to activating a new zone configuration. This can be determined by querying the activeZoneCfgNumberBySwitch object and ensuring that none of the 2xx codes are returned. NOTE: Value returned for the GET command is meaningless for this MIB object. If any of the switches are not activated, an error response will be returned.
