How to Install and Configure a Two-Node Cluster for Oracle Solaris Cluster 4.1 Using SR-IOV/IB Interfaces
by Venkat Chennuru
Published September 2014
How to quickly and easily install and configure Oracle Solaris Cluster 4.1 software for two nodes, including configuring a quorum device.
This article is intended to help a new or experienced Oracle Solaris user to quickly and easily install and configure Oracle Solaris Cluster software for two nodes, including the creation of Single Root I/O Virtualization/InfiniBand (SR-IOV/IB) devices. It provides a step-by-step procedure to simplify the process.
This article does not cover the configuration of highly available services. For more details on how to install and configure other Oracle Solaris Cluster software configurations, see the Oracle Solaris Cluster Software Installation Guide.
This articles uses the interactive
scinstall utility to configure all the nodes of a cluster quickly and easily. The interactive
scinstall utility is menu driven. The menus help reduce the chance of mistakes and promote best practices by using default values and prompting you for information specific to your cluster. The utility also helps prevent mistakes by identifying invalid entries. Finally, the
scinstall utility eliminates the need to manually set up a quorum device by automating the configuration of a quorum device for your new cluster.
Note: This article applies to the Oracle Solaris Cluster 4.1 release. For more information about the Oracle Solaris Cluster release, see the Oracle Solaris Cluster 4.1 Release Notes.
Overview of SR-IOV
SR-IOV is a PCI-SIG standards-based I/O virtualization specification. SR-IOV enables a PCIe function known as physical function (PF) to create multiple lightweight PCIe functions known as virtual functions (VFs). VFs show up like a regular PCIe functions and also operate like regular PCIe functions. The address space for a VF is well contained so that a VF can be assigned to a virtual machine (a logical domain or LDom) with the help of a hypervisor. SR-IOV provides a high degree of sharing compared to other forms of direct hardware access methods that are available in LDom technology, that is, PCIe bus assignment and direct I/O.
Prerequisites, Assumptions, and Defaults
This section discusses several prerequisites, assumptions, and defaults for two-node clusters.
This article assumes the following configuration is used:
You are installing the two-node cluster on Oracle Solaris 11.1 and you have basic system administration skills.
You are installing the Oracle Solaris Cluster 4.1 software.
The cluster hardware is a supported configuration for Oracle Solaris Cluster 4.1 software.
This is a two-node cluster for SPARC T4-4 servers from Oracle. SR-IOV is only supported on servers based on Oracle's SPARC T4 (or above) processors.
Each cluster node is an I/O domain.
Each node has two spare network interfaces to be used as private interconnects, also known as transports, and at least one network interface that is connected to the public network.
iSCSI shared storage is connected to the two nodes.
Your setup looks like Figure 1. You might have fewer or more devices, depending on your system or network configuration.
In addition, it is recommended that you have console access to the nodes during cluster installation, but this is not required.
Figure 1. Oracle Solaris Cluster Hardware Configuration
Perform the following prerequisite tasks:
- Ensure that Oracle Solaris 11.1 SRU13 is installed on both the SPARC T4-4 systems.
- Perform the initial preparation of public IP addresses and logical host names.
You must have the logical names (host names) and IP addresses of the nodes to configure a cluster. Add those entries to each node's
/etc/inet/hostsfile or to a naming service if such a service (for example, DNS, NIS, or NIS+ maps) is used. The example in this article uses a NIS service.
Table 1 lists the configuration used in this example.
Table 1. Configuration
Component Name Interface IP Address cluster
— — node 1
22.214.171.124 node 2
- Create SR-IOV VF devices for the public, private, and storage networks.
You have to create the VF devices on the corresponding adapters for public, private, and storage networks in the primary domain and assign the VF devices to the logical domains that will be configured as cluster nodes.
Type the commands shown in Listing 1 on the control domain
root@phys-primary-1# ldm ls-io|grep IB /SYS/PCI-EM0/IOVIB.PF0 PF pci_0 primary /SYS/PCI-EM1/IOVIB.PF0 PF pci_0 primary /SYS/PCI-EM0/IOVIB.PF0.VF0 VF pci_0 primary root@phys-primary-1# ldm start-reconf primary root@phys-primary-1# ldm create-vf /SYS/MB/NET2/IOVNET.PF0 root@phys-primary1# ldm create-vf /SYS/PCI-EM0/IOVIB.PF0 root@phys-primary-1# ldm create-vf /SYS/PCI-EM1/IOVIB.PF0 root@phys-primary-1# ldm add-domain domain1 root@phys-primary-1# ldm add-vcpu 128 domain1 root@phys-primary-1# ldm add-mem 128g domain1 root@phys-primary-1# ldm add-io /SYS/MB/NET2/IOVNET.PF0.VF1 domain1 root@phys-primary-1# ldm add-io /SYS/PCI-EM0/IOVIB.PF0.VF1 domain1 root@phys-primary-1# ldm add-io /SYS/PCI-EM1/IOVIB.PF0.VF1 domain1 root@phys-primary-1# ldm ls-io | grep domain1 /SYS/MB/NET2/IOVNET.PF0.VF1 VF pci_0 domain1 /SYS/PCI-EM0/IOVIB.PF0.VF1 VF pci_0 domain1 /SYS/PCI-EM0/IOVIB.PF0.VF2 VF pci_0 domain1
IOVNET.PF0.VF1is used for the public network. IB VF devices have partitions that host both private network and storage network devices.
Repeat the commands shown in Listing 1 on
phys-primary-2. The I/O domain
domain1on both nodes must be installed with Oracle Solaris 11.1 SRU13 before installing the cluster software.
Note: To learn more about SR-IOV technology, take a look at the documentation for Oracle VM Server for SPARC 3.1. For information about InfiniBand VFs, see "Using InfiniBand SR-IOV Virtual Functions."
scinstall interactive utility in the Typical mode installs the Oracle Solaris Cluster software with the following defaults:
Private-network address 172.16.0.0
Private-network netmask 255.255.248.0
Perform the Preinstallation Checks
- Temporarily enable
rooton the cluster nodes.
- Log in to the cluster node on which you are installing Oracle Solaris Cluster software and become superuser.
- On each node, verify the
/etc/inet/hostsfile entries. If no other name resolution service is available, add the name and IP address of the other node to this file.
/etc/inet/hostsfile on node 1 has the following information.
# Internet host table # ::1 phys-schost-1 localhost 127.0.0.1 phys-schost-1 localhost loghost
/etc/inet/hostsfile on node 2 has the following information.
# Internet host table # ::1 phys-schost-2 localhost 127.0.0.1 phys-schost-2 localhost loghost
- On each node, verify that at least one shared storage disk is available.
In this example, the following disks are shared between the two nodes:
# format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c4t0d0 <FUJITSU-MBB2073RCSUN72G-0505 cyl 8921 alt 2 hd 255 sec 63> /pci@7b,0/pci1022,7458@11/pci1000,3060@2/sd@0,0 /dev/chassis/SYS/HD0/disk 1. c4t1d0 <SUN72G cyl 14084 alt 2 hd 24 sec 424> /pci@7b,0/pci1022,7458@11/pci1000,3060@2/sd@1,0 /dev/chassis/SYS/HD1/disk 2. c0t600144F0CD152C9E000051F2AFE20007d0 <SUN-ZFS Storage 7420-1.0 cyl 648 alt 2 hd 254 sec 254> /scsi_vhci/ssd@g600144f0cd152c9e000051f2afe20007 3. c0t600144F0CD152C9E000051F2AFF00008d0 <SUN-ZFS Storage 7420-1.0 cyl 648 alt 2 hd 254 sec 254> /scsi_vhci/ssd@g600144f0cd152c9e000051f2aff00008
- On each node, ensure that the right OS version is installed.
# more /etc/release Oracle Solaris 11.1 SPARC Copyright (c) 1983, 2013, Oracle and/or its affiliates. All rights reserved. Assembled 06 November 2013
- Ensure that the network interfaces are configured as static IP addresses (not DHCP or of type
addrconf, as displayed by the
ipadm show-addr -o allcommand.)
If the network interfaces are not configured as static IP addresses, then run the command shown in Listing 2 on each node, which will unconfigure all network interfaces and services.
If the nodes are configured as static, go to the "Configure the Oracle Solaris Cluster Publisher" section.

- On each node, type the following commands to configure the naming services and update the name service switch configuration:
# svccfg -s svc:/network/nis/domain setprop config/domainname = hostname: nisdomain.example.com # svccfg -s svc:/network/nis/domain:default refresh # svcadm enable svc:/network/nis/domain:default # svcadm enable svc:/network/nis/client:default # /usr/sbin/svccfg -s svc:/system/name-service/switch setprop config/host = astring: \"files nis\" # /usr/sbin/svccfg -s svc:/system/name-service/switch setprop config/netmask = astring: \"files nis\" # /usr/sbin/svccfg -s svc:/system/name-service/switch setprop config/automount = astring: \"files nis\" # /usr/sbin/svcadm refresh svc:/system/name-service/switch
- Bind each node to the NIS server.
# ypinit -c
- Reboot each node to make sure that the new network setup is working fine.
Configure the Oracle Solaris Cluster Publisher
There are two main ways to access the Oracle Solaris Cluster package repository, depending on whether the cluster nodes have direct access (or through a web proxy) to the internet: using a repository hosted on
pkg.oracle.com or using a local copy of the repository.
Using a Repository Hosted on
To access either the Oracle Cluster Solaris Release or Support repositories, obtain the SSL public and private keys.
- Go to http://pkg-register.oracle.com/register/repos/.
- Choose the Oracle Solaris Cluster Release or Support repository.
- Accept the license.
- Request a new certificate by choosing the Oracle Solaris Cluster software and submitting a request. This displays a certification page that contains download buttons for download the key and certificate files.
- Download the key and certificate files and install them, as described in the returned certification page.
- Configure the
ha-clusterpublisher with the downloaded SSL keys to point to the selected repository URL on
This example uses the release repository:
# pkg set-publisher \ -k /var/pkg/ssl/Oracle_Solaris_Cluster_4.key.pem \ -c /var/pkg/ssl/Oracle_Solaris_Cluster_4.certificate.pem \ -g https://pkg.oracle.com/ha-cluster/release/ ha-cluster
Using a Local Copy of the Repository
To access a local copy of the Oracle Solaris Cluster Release or Support repository, download the repository image.
- Download the repository image from the Oracle Technology Network or Oracle Software Delivery Cloud.
To download the repository image from Oracle Software Delivery Cloud, select Oracle Solaris as the Product Pack on the Media Pack Search Page.
- Mount the repository image and copy the data to a shared file system that all the cluster nodes can access.
# mount -F hsfs <path-to-iso-file> /mnt # rsync -aP /mnt/repo /export # share /export/repo
- Configure the
This example uses node 1 as the system that shared the local copy of the repository:
# pkg set-publisher -g file:///net/phys-schost-1/export/repo ha-cluster
Install the Oracle Solaris Cluster Software Packages
- On each node, ensure that the correct Oracle Solaris package repositories are published.
If they are not, unset the incorrect publishers and set the correct ones. The installation of the
ha-clusterpackages is highly likely to fail if it cannot access the
# pkg publisher PUBLISHER TYPE STATUS URI solaris origin online <solaris repository> ha-cluster origin online <ha-cluster repository>
- On each cluster node, install the
# pkg install ha-cluster-full Packages to install: 68 Create boot environment: No Create backup boot environment: Yes Services to change: 1 DOWNLOAD PKGS FILES XFER (MB) Completed 68/68 6456/6456 48.5/48.5$<3> PHASE ACTIONS Install Phase 8928/8928 PHASE ITEMS Package State Update Phase 68/68 Image State Update Phase 2/2 Loading smf(5) service descriptions: 9/9 Loading smf(5) service descriptions: 57/57
Configure the Oracle Solaris Cluster Software
- On each node of the cluster, identify the network interfaces that will be used for the private interconnects.
In this example, 8513 and 8514 are the PKEYs for a private IB partition that is used for transport. 8503 is the PKEY for a private storage network that is used to configure iSCSI storage from an Oracle ZFS Storage Appliance with an IB connection.
The Oracle ZFS Storage Appliance has the IP address 192.168.0.61 configured on the InfiniBand network. The
priv2IB partitions are used as private interconnects for the private network. The
storage2partitions are used for the storage network.
Type the following commands on node 1:

The "dlpi" transport type will be set for this cluster. For node "phys-schost-2", Name of the switch to which "priv1" is connected [switch1]? Each adapter is cabled to a particular port on a switch. And, each port is assigned a name. You can explicitly assign a name to each port. Or, for Ethernet and Infiniband switches, you can choose to allow scinstall to assign a default name for you. The default port name assignment sets the name to the node number of the node hosting the transport adapter at the other end of the cable. For node "phys-schost-2", Use the default port name for the "priv1" connection (yes/no) [yes]? Select the second cluster transport adapter: 1) net1 2) net2 3) net3 4) net4 5) net5 6) priv1 7) priv2 8) Other Option: 7 Adapter "priv2" is an Infiniband adapter.

For node "phys-schost-2", Use the default port name for the "priv2" connection (yes/no) [yes]?
The next screen configures the quorum device. Select the default answers for the questions asked in the Quorum Configuration screen.
>>> Quorum Configuration <<< Every two-node cluster requires at least one quorum device. By default, scinstall selects and configures a shared disk quorum device for you. This screen allows you to disable the automatic selection and configuration of a quorum device. You have chosen to turn on the global fencing. If your shared storage devices do not support SCSI, such as Serial Advanced Technology Attachment (SATA) disks, or if your shared disks do not support SCSI-2, you must disable this feature. If you disable automatic quorum device selection now, or if you intend to use a quorum device that is not a shared disk, you must instead use clsetup(1M) to manually configure quorum once both nodes have joined the cluster for the first time. Do you want to disable automatic quorum device selection (yes/no) [no]? Is it okay to create the new cluster (yes/no) [yes]? During the cluster creation process, cluster check is run on each of the new cluster nodes. If cluster check detects problems, you can either interrupt the process or check the log files after the cluster has been established. Interrupt cluster creation for cluster check errors (yes/no) [no]?
The final screens print details about the configuration of the nodes and the installation log's file name. The utility then reboots each node in cluster mode.

scinstallutility finishes, the installation and configuration of the basic Oracle Solaris Cluster software is complete. The cluster is now ready for you to configure the components you will use to support highly available applications. These cluster components can include device groups, cluster file systems, highly available local file systems, and individual data services and zone clusters. To configure these components, refer to the Oracle Solaris Cluster 4.1 documentation library.

Verify High Availability (Optional)
This section describes how to create a failover resource group with a
LogicalHostname resource for a highly available network resource and an
HAStoragePlus resource for a highly available ZFS file system on a zpool resource.
- Identify the network address that will be used for this purpose and add it to the
/etc/inet/hostsfile on the nodes. In this example, the host name is
/etc/inet/hostsfile on node 1 contains the following information:
# Internet host table # ::1 localhost 127.0.0.1 localhost loghost 126.96.36.199 phys-schost-1 # Cluster Node 188.8.131.52 phys-schost-2 # Cluster Node 184.108.40.206 schost-lh
/etc/inet/hostsfile on node 2 contains the following information:
# Internet host table # ::1 localhost 127.0.0.1 localhost loghost 220.127.116.11 phys-schost-1 # Cluster Node 18.104.22.168 phys-schost-2 # Cluster Node 22.214.171.124 schost-lh
schost-lhwill be used as the logical host name for the resource group in this example. This resource is of the type
SUNW.LogicalHostname, which is a preregistered resource type.
- From one of the nodes, create a zpool with the two shared storage disks
/dev/did/rdsk/d2s0. In this example, the entire disk is assigned to slice 0 of the disks, using the
# zpool create -m /zfs1 pool1 mirror /dev/did/dsk/d1s0 /dev/did/dsk/d2s0 # df -k /zfs1 Filesystem 1024-blocks Used Available Capacity Mounted on pool1 20514816 31 20514722 1% /zfs1
The created zpool will now be placed in a highly available resource group as a resource of type
SUNW.HAStoragePlus. This resource type has to be registered before it is used for the first time.
- To create a highly available resource group to house the resources, on one node, type the following command:
# /usr/cluster/bin/clrg create test-rg
- Add the network resource to the
# /usr/cluster/bin/clrslh create -g test-rg -h schost-lh schost-lhres
- Register the storage resource type.
# /usr/cluster/bin/clrt register SUNW.HAStoragePlus
- Add the zpool to the group.
# /usr/cluster/bin/clrs create -g test-rg -t SUNW.HAStoragePlus -p zpools=pool1 hasp-res
- Bring the group online:
# /usr/cluster/bin/clrg online -eM test-rg
- Check the status of the group and the resources:
# /usr/cluster/bin/clrg status === Cluster Resource Groups === Group Name Node Name Suspended Status ---------- --------- --------- ------ test-rg phys-schost-1 No Online phys-schost-2 No Offline # /usr/cluster/bin/clrs status === Cluster Resources === Resource Name Node Name State Status Message ------------- ------- ----- -------------- hasp-res phys-schost-1 Online Online phys-schost-2 Offline Offline schost-lhres phys-schost-1 Online Online - LogicalHostname online. phys-schost-2 Offline Offline
The command output shows that the resources and the group are
