9.2.2 Checking the Assignment Status of I/O Devices


9.2.2 Checking the Assignment Status of I/O Devices
Log in to Oracle Solaris on the control domain to check the operation status of logical domains and the assignment status of resources such as I/O devices to logical domains.
For details on the commands used here, see "3.2 Operations and Commands Related to Logical Domain Configurations" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide.
  1. Check the operation status of logical domains.
    The following example shows execution of the command for checking the operation status of logical domains defined in the physical partition.
primary# ldm list-domain

*1 The control domain is in operation with 32 cores of virtual CPUs and 16 GB of memory assigned.
*2 The domain (guest) is in operation with 32 cores of virtual CPUs and 16 GB of memory assigned.
  1. Check the virtual services that are configured in the control domain.
    The following example shows execution of the command for checking the virtual services configured in the control domain.
primary# ldm list-services

*1 The set port number of a virtual console is in a range of 5000 to 5100.
*2 The physical LAN port net0 is assigned to the virtual switch primary-vsw0.
*3 The physical LAN port net4 is assigned to the virtual switch primary-vsw4.
*4 vdisk00 is assigned to the virtual disk service primary-vds0.
  1. Check the physical locations of the physical LAN ports.
    The following example shows execution of the command for checking the physical locations of the physical LAN ports.
# dladm show-phys -L

*1 The location of net0 is the on-board LAN of BB#00.
  1. Check the assignment status of resources to logical domains.
    The following example shows execution of the command for checking the resources assigned to a logical domain (domain name: guest).
# ldm list-bindings guest

*1 The root complex PCIE0 is assigned as shown to the control domain.
*2 The PCIe endpoint of PCI slot #6 of BB#00 is assigned as shown to the logical domain ldom.
*3 An I/O device with the SR-IOV virtual function enabled is assigned as shown to the control domain.
To perform maintenance on a PCIe card, write down the results output by the ldm list-io command, because they will be needed later to restore the system after the maintenance.
