- List all logical devices known on this system with detailed information.
The command lists device information for all logical devices on this system. The information includes the name (UUID), device type, display name, and multipathing plugin. Specify thevicfg-scsidevs <conn_options> --list--deviceoption to only list information about a specific device. The following example shows output for two devices. The actual listing might include multiple devices and the precise format differs between releases.mpx.vmhba2:C0:T1:L0 Device Type: cdrom Size: 0 MB Display Name: Local HL-DT-ST (mpx.vmhba2:C0:T1:L0) Plugin: NMP Console Device: /vmfs/devices/cdrom/mpx.vmhba2:C0:T1:L0 Devfs Path: /vmfs/devices/cdrom/mpx.vmhba2:C0:T1:L0 Vendor: SONY Model: DVD-ROM GDRXX8XX Revis: 3.00 SCSI Level: 5 Is Pseudo: Status: Is RDM Capable: Is Removable: Other Names: vml.000N000000XXXdXXXXXXXXaXXXaXX VAAI Status: nnnn naa.60060...

The information includes the device ID, device type, size, plugin, and device display name.vicfg-scsidevs <conn_options> --compact-list - List all device unique identifiers.
The command lists the primary UID for each device, such asvicfg-scsidevs <conn_options> --uidsnaa.xxxor other primary name, and any other UIDs for each UID (VML name). You can specify--deviceto only list information for a specific device. - List a specific logical device with its detailed information.vicfg-scsidevs <conn_options> -l -d mpx.vmhba32:C0:T1:L0
- Print mappings for VMFS volumes to the corresponding partition, path to that partition, VMFS uuid, extent number, and volume names.vicfg-scsidevs <conn_options> --vmfs
- Print HBA devices with identifying information.
The return value includes the adapter ID, driver ID, adapter UID, PCI, vendor, and model.vicfg-scsidevs <conn_options> --hbas - Print a mapping between HBAs and the devices it provides paths to.vicfg-scsidevs <conn_options> --hba-device-list
