Last updated on AUGUST 27, 2017
Applies to:Solaris Operating System - Version 11.1 to 11.2 [Release 11.0]
Information in this document applies to any platform.
Please refer to:
Oracle® VM Server for SPARC 3.2 Administration Guide
Using Fibre Channel SR-IOV Virtual Functions
OVM 3.1 does not support virtualized tape drive via SR-IOV.
However connection to guest LDOMs is possible using DIO (Direct IO)
You will need to map at least one PCIe slot into the relevant guest domain, with the HBA for the tape drive (scsi or fc) seated in that slot.
This can be done with SDIO (one slot) or by assigning a PCIe root complex to the guest.
SPARC M7 series server, SPARC T7 series server, and SPARC S7 series server: The direct I/O feature is not supported , as explained on: Oracle VM Server for SPARC 3.4 Administration Guide , Chapter 9, Current Direct I/O Feature Limitations
Note - The direct I/O feature is not supported on the SPARC M7 series server, SPARC T7 series server, and SPARC S7 series server.
Instead, use the PCIe bus assignment feature. See Creating a Root Domain by Assigning PCIe Buses.
