SPARC Logical Domains: Alternate Service Domains Part 3

In Part One of this series we went through the initial configuration of our Logical Domain hypervisor, and took some time to explain the process of mapping out the PCI Root Complexes, so that we would be able to effectively split them between the primary and an alternate domain. In Part Two of this series we took the  information from Part One and split out […]

SPARC Logical Domains: Alternate Service Domains Part 1

In this series we will be going over configuring alternate I/O and Service domains, with the goal of increasing the serviceability the SPARC T-Series servers without impacting other domains on the hypervisor.  Essentially enabling rolling maintenance without having to rely on live migration or downtime.  It is important to note, that this is not a cure-all, for example base firmware updates would still be interruptive, […]

SPARC Logical Domains: Live Migration

One of the ways that we are able to accomplish regularly scheduled maintenance is by utilizing Live Migration, with this we can migrate workloads from one physical machine to another without having service interruption.  The way that it is done with Logical Domains is much more flexible than with most other hypervisor solutions, it doesn’t require any complicated cluster setup, no management layer, so you […]

Solaris 11: Configure IP Over Infiniband Devices

In this article we will be going over the configuration of an infiniband interface with the IPoIB protocol on Solaris 11, specifically Solaris 11.2 (previous versions of Solaris 11 should work the same, however there have been changes in the ipadm and dladm commands). Identify Infiniband Datalinks First we need to identify the underlying interfaces of the infiniband interfaces.  In my case net2 and net3. […]

Adventures in ZFS: Mirrored Rpool

It always makes sense to have a mirrored rpool for your production systems, however that is not always how they are configured.  This really simple procedure is also critical. Create a Mirrored Zpool Check the existing devices to identify the one currently in use. Once we know which one is currently in use, we need to find a different one to mirror onto. Then we […]

Solaris 11: Install Bind Server

Today I am going to document the process of install BIND in Solaris 11.  I am using a Solaris 11.1 zone for this task, though nothing in this is specific to zones, and it should work on previous versions of Solaris 11.  I have done this quite a few times and it is not a very intuitive process.  As of the time of this writing […]

Solaris Networking: Datalink Multipathing Protocol

In this article we are going to go over Datalink Multipathing Protocol (DLMP) available in Solaris.  DLMP is similar to IPMP, however there are some key differences, the biggest being the layer at which it operates.  DLMP operates at the datalink layer of the OSI model, while IPMP operates at the network layer.  Due to the differences in those layers DLMP opens up a lot […]

Solaris SMF: Define File Dependency

One of the biggest benefits of migrating to the Service Management Framework is that we can introduce dependencies to a services, these dependencies can be other services which is very valuable, however they can also be file based.  This can be used in a number of ways, say for example you have some application trees that live on some NFS mounts, in the event that […]
