Virtual Disk Appearance

When a back end is exported as a virtual disk, it can appear in the guest domain either as a full disk or as a single-slice disk. The way it appears depends on the type of the back end and on the options used to export it.

Note:

Non-Volatile Memory Express (NVMe) storage is available starting with the SPARC T7, SPARC M7, and SPARC S7 series server. This storage can be a disk drive or a Flash Accelerator F160 PCIe card. This disk type can be used to build a virtual disk back end. Starting with the Oracle Solaris 11.3 SRU 2.4 OS, you can use the NVMe storage disk type as a full disk or as a single-slice disk. Prior to the Oracle Solaris 11.3 SRU 2.4 OS, you can use the NVMe storage disk type only as a single-slice disk.

Caution:

Single-slice disks do not have device IDs. If a device ID is required, use a full physical disk backend.
