About the NetApp SnapDrive agent
The NetApp SnapDrive agent monitors, connects, and disconnects filer volumes. You can configure the agent to use the iSCSI or the FC protocol.
The NetApp SnapDrive agent functions are as follows:
Online | Connects a virtual disk (LUN) using an iSCSI or an FC initiator. The agent presents the LUN as a locally-attached drive to the host. The agent also removes LUN-host mappings made before the online operation. |
Offline | Disconnects the virtual disk (LUN) from the host. |
Monitor | Verifies that the specified virtual disk (LUN) is connected to the host. |
Open | Verifies that there is connectivity to the filer. It also checks that the VCS Helper service is running with the same privileges as the SnapDrive service. |
Clean | Attempts to forcibly disconnect a virtual disk (LUN). |
NetApp SnapDrive agent resource type definition and attribute definitions are as follows. This information will assist you during the agent configuration.
NetApp SnapDrive agent is configured as a resource of type NetAppSnapDrive.
type NetAppSnapDrive ( static int MonitorInterval = 30 static int NumThreads = 1 static i18nstr ArgList[] = { FilerResName, "FilerResName:FilerName", "FilerResName:StorageIP", VolumeName, ShareName, LUN, MountPath, Initiator, InitiatorMonitorInterval } str FilerResName str VolumeName str ShareName str LUN str MountPath str Initiator[] int InitiatorMonitorInterval = 30 )
The following table describes the NetApp SnapDrive agent attributes.
Attribute | Description |
---|---|
FilerResName | Name of the VCS NetAppFiler-type resource in the service group. Type and dimension: string-scalar |
VolumeName | Name of the volume containing the virtual disk. Define the volume name in the same case as on the filer. Type and dimension: string-scalar |
ShareName | Name of the CIFS share containing the virtual disk. Type and dimension: string-scalar |
LUN | Name of the LUN (virtual disk) on the filer that is presented to the host for mounting. Define the LUN name in the same case as on the filer. Type and dimension: string-scalar |
MountPath | Drive letter to be assigned to the virtual disk. Type and dimension: string-scalar |
Initiator | Name of iSCSI or FC initiator the host uses to connect virtual disks. You can retrieve this value from the Disk Management console. Type and dimension: string-vector |
