How to Create an I/O Domain by Assigning a PCIe Endpoint Device
Plan all DIO deployments ahead of time to minimize downtime.
Caution:
Theprimary
domain loses access to the on-board DVD device if you assign the /SYS/MB/SASHBA1
slot on a SPARC T4-1 system to a DIO domain.
The SPARC T4-1 system includes two DIO slots for on-board storage, which are represented by the /SYS/MB/SASHBA0
and /SYS/MB/SASHBA1
paths. In addition to hosting multiheaded on-board disks, the /SYS/MB/SASHBA1
slot hosts the on-board DVD device. So, if you assign /SYS/MB/SASHBA1
to a DIO domain, the primary
domain loses access to the on-board DVD device.
The SPARC T4-2 system has a single SASHBA
slot that hosts all on-board disks as well as the on-board DVD device. So, if you assign SASHBA
to a DIO domain, the on-board disks and the on-board DVD device are loaned to the DIO domain and unavailable to the primary
domain.
For an example of adding a PCIe endpoint device to create an I/O domain, see Planning PCIe Endpoint Device Configuration.
Note:
For Oracle Solaris 11 releases prior to Oracle Solaris 11.4, use theDefaultFixed
NCP to configure datalinks and network interfaces on Oracle Solaris 11 systems.
The Oracle Solaris 11 OS includes the following NCPs:
-
DefaultFixed
– Enables you to use thedladm
oripadm
command to manage networking -
Automatic
– Enables you to use thenetcfg
ornetadm
command to manage networking
DefaultFixed
NCP is enabled by using the netadm list
command. See Chapter 7, Using Datalink and Interface Configuration Commands on Profiles in Oracle Solaris Administration: Network Interfaces and Network Virtualization.
