How to Create a Datalink in Non-Global Zone from the Global Zone in Solaris 11
Network virtualization is the process of combining hardware network resources and software network resources into a single administrative unit. The goal of network virtualization is to provide systems and users with efficient, controlled, and secure sharing of the networking resources. The end product of network virtualization is the virtual network. Starting from Oracle Solaris 11.2, you can create datalinks in nonglobal zones from the global zone. This feature enables administrators to … [Read more...] about How to Create a Datalink in Non-Global Zone from the Global Zone in Solaris 11
How to configure a vnic on top of a Vlan Tagged Interface and assign the vnic to a Solaris 11 Zone
This post discusses how to assign a vnic created on a vlan tagged interface and assign the vnic to an exclusive-ip zone in Solaris 11. If you want a vnic on a vlan, you need to set the vlan option when you create the vnic. Note that the physical does not have to be on the vlan, but the external cisco switch connected to the physical does need to be vlan aware. Once you do create the vnic on a vlan and assign it to the NGZ, that doesn't mean you will have communications to the GZ. The GZ will … [Read more...] about How to configure a vnic on top of a Vlan Tagged Interface and assign the vnic to a Solaris 11 Zone
Solaris 11 : How to verify whether I’m logged into a Kernel Zone?
What is a Solaris Kernel Zone The solaris-kz brand uses the branded zones framework to run zones with a separate kernel and OS installation from that used by the global zone. A solaris-kz installation is independent of that of the global zone; it is not a pkg linked image and can be modified regardless of the global zone content. A solaris-kz zone can be installed in the same manner as other brands directly from the global zone, or via a boot media. How to indentify if you are in a kernel … [Read more...] about Solaris 11 : How to verify whether I’m logged into a Kernel Zone?

On the global zone, enter the zone configuration mode : global_zone # zonecfg -z zone01 zonecfg:zone01> add net … [Read more...] about Solaris zones : How to set netmasks
Solaris 11.2 : Adding new resources to a running zone online
Solaris 11.2 provides a supported way to add new resources to a running zone online. Prior to this version, a reboot of the non-global zone was required to make the changes effective. The post describes an example of adding a raw disk device online to a non-global zone. Example: 1. Check the Solaris OS version. # uname -a SunOS test 5.11 11.2 sun4v sparc SUNW,T5240 2. List the zones available on the system. In our example we will be adding disk resource to the zone - zone01 # zoneadm … [Read more...] about Solaris 11.2 : Adding new resources to a running zone online
How to delegate NTP service to non-global zone in Solaris
A system with non-global zones will share one kernel for all zones (the global zone as well as all configured non-global zone). As a result, there is only one date/time on the entire setup and this time is usually controlled by the global zone only. By default, the privilege to change the date and time is not available inside a non-global zone and therefore the NTP service will fail to adjust the time. The default configuration for non-global zones assumes that the time synchronization is … [Read more...] about How to delegate NTP service to non-global zone in Solaris
Solaris 10 zones troubleshooting : Unable to Share NFS File Systems From a Non-global Zone
Question : I am unable to share nfs from a non-global zone. Answer : Consider the following example. - sysadmin creates a non-global zone and wants to share a zfs mount point from non-global zone. - While setting ZFS parameter "sharenfs", he encounters an error : cannot set property for 'findisk/faktudt_users': 'sharenfs' cannot be set on dataset in a non-global zone - Another case is when ufs file system is shared from the non-globa zone using the /etc/dfs/dfstab file or on command … [Read more...] about Solaris 10 zones troubleshooting : Unable to Share NFS File Systems From a Non-global Zone
How to configure additional IP address on the same interface in solaris zones
Question : Can I configure additional IP addresses on the same interface in non-global zone? If yes, how? Answer : Yes, you can add additional IP addresses on the existing interface configured in the non global zone. In fact the procedure remains the same. To add a secondary shared interface to configured shared ip zone you would use the zonecfg command. Below is an example of adding a second interface in a zone named zone01 that will be persistent upon reboots. In this example, the … [Read more...] about How to configure additional IP address on the same interface in solaris zones
