Display information about Data ONTAP-v system disks

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The system node virtual-machine instance show-system-disks command displays the system disks information of the Data ONTAP node running on the virtual machine. There are three types of Data ONTAP-v system disks - boot, core and log. The details contain the physical properties of the disk and its backing information (e.g. backing store name, iSCSI Lun UUID, etc). To filter command output, specify any number of optional fields listed below.

Parameters

{ [-fields <fieldname>,…​]

If you specify the -fields <fieldname>, …​ parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.

[-node {<nodename>|local}] - Node Name

The name of the Data ONTAP node running in a virtual machine for which information is to be displayed. If this optional parameter is not specified, the command displays information about all nodes in the cluster.

[-vmdisk-type <text>] - Type of the System Disk

The type of the system disk, for example "Boot", "Core" or "Log". This optional parameter selects the information about the system disk with the specified type.

[-vmdisk-name <text>] - Data ONTAP Supplied Name of the System Disk

The Data ONTAP-supplied name of the system disk. This optional parameter selects the information about the system disk with the specified name.

[-vmdisk-serial-number <text>] - Data ONTAP Supplied Serial Number of the System Disk

The Data ONTAP-supplied serial number of the system disk. This optional parameter selects the information about system disk with the specified serial number.

[-vmdisk-capacity {<integer>[KB|MB|GB|TB|PB]}] - Size of the System Disk

The size of the system disk. This optional parameter selects the information about system disks with the specified size.

[-vmdisk-area-name <text>] - Name of the System Disk Backing Store

The name of the disk backing store. A backing store represents a storage location for virtual machine files. It can be a VMFS volume, a directory on network-attached storage, or a local file system path. This optional parameter selects the information about the system disks that reside on the specified backing store.

[-vmdisk-file-name <text>] - File Name of the System Disk Used By the Hypervisor

The file name of the virtual disk used by the hypervisor. Each Data ONTAP disk is mapped to a unique VM disk file. This optional parameter selects the information about the system disk mapped to the specified file name.

[-vmdisk-backing-store-type <text>] - Type of the System Disk Backing Store

The type of the disk backing store. It can be a VMFS volume, a directory on network-attached storage, or a local file system path. This optional parameter selects the information about the system disks that are backed by the specified type.

[-vmdisk-backing-store-capacity {<integer>[KB|MB|GB|TB|PB]}] - Size of the System Disk Backing Store

The size of the disk backing store. This optional parameter selects the information about the system disks that are backed by stores with the specified capacity.

[-vmdisk-backing-store-nas-path <text>] - Full Path to the Backing Store for NAS

The full path to the backing store for network-attached storage. This optional parameter selects the information about the system disks with the specified NAS path.

[-vmdisk-backing-adapter-pci <text>] - Backing Adapter PCI Device ID

The backing adapter PCI device ID for the virtual disk. This optional parameter selects the information about the system disks that have the specified ID as their backing adapter PCI ID.

[-vmdisk-backing-adapter-device <text>] - Name of the Backing Adapter Device

The name of the backing adapter device. This optional parameter selects the information about the system disks that have the specified name as their backing adapter device name.

[-vmdisk-backing-adapter-model <text>] - Type of the Backing Adapter Model

The type of the backing adapter model. This optional parameter selects the information about the system disks that have the specified type as their backing adapter model type.

[-vmdisk-backing-adapter-driver <text>] - Backing Adapter Driver Name of the Initiator

The backing adapter driver name of the initiator. This optional parameter selects the information about the system disks that have the specified name as their initiator’s backing adapter driver name.

[-vmdisk-backing-target-iscsi-name <text>] - iSCSI Name of the System Disk Backing Target

The iSCSI name of the disk backing target. This field is valid only for iSCSI connections. This optional parameter selects the information about the system disks that have the specified name as their backing device iSCSI target name.

[-vmdisk-backing-target-iscsi-address <text>] - iSCSI IP Address of the System Disk Backing Target

The iSCSI IP address of the disk backing target. This field is valid only for iSCSI connections. This optional parameter selects the information about the system disks that have the specified IP as their backing device iSCSI target IP address.

[-vmdisk-backing-device-address <text>] - SCSI Device Name (target-id:lun-id) for the Backing Disk

The SCSI device name for the backing disk. It takes the form target-id:lun-id, for example "2:1". This optional parameter selects the information about the system disks that have the specified backing device address.

[-vmdisk-backing-device-uuid <text>] - Hypervisor-Assigned Unique ID of the Backing Device

The hypervisor-assigned unique ID of the backing device (disk or LUN). This optional parameter selects the information about system disks that are backed by a device with the specified UUID.

[-vmdisk-backing-device-partition <integer>] - Backing Disk Partition Number for the VM Disk File

The backing disk partition number where the corresponding VM disk file resides. This optional parameter selects the information about the system disks that reside on the specified partition number on any disk.

[-vmdisk-backing-device-capacity {<integer>[KB|MB|GB|TB|PB]}] - Size of the Backing Device (Disk or LUN)

The size of the backing device (disk or LUN) in bytes. This optional parameter selects the information about the system disks that have backing devices with the specified capacity.

Examples

The following example shows typical output from the system node virtual-machine instance show-system-disks command for the Data ONTAP node running on a virtual machine.

cluster1::> system node virtual-machine instance show-system-disks
