Physical Disk Slice

A physical disk slice is always exported as a single-slice disk. In that case, virtual disk drivers (vds and vdc) forward I/O from the virtual disk and act as a pass-through to the physical disk slice.

A physical disk slice is exported from a service domain by exporting the corresponding slice device. If the device is different from slice 2 then it is automatically exported as a single-slice disk regardless of whether you specify the slice option. If the device is the slice 2 of the disk, you must set the slice option to export only slice 2 as a single-slice disk. Otherwise, the entire disk is exported as full disk.


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.

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.
