Solaris 11.3 accepted shared devices that used the normal multi pathing names like /dev/dsk/c0t600C0FF0003B286921E7BD5B01000000d0 but Solaris 11.4 won’t recognize these as shared devices when you try to live migrate a zone: You’ll need to convert these paths to use the luname format. This is described in the Oracle documentation, but here’s what you need to do. NOTE you’ll need…

If you’re looking to use live migration with your Solaris 11 kernel zones, you’ll need to get your zone onto shared storage. In Solaris zone terminology, shared storage is storage that can be accessed by multiple hosts using the same device names. In this post, we’ll be using fiber channel storage and the built-in multi-pathing…
Read More →When you upgrade your Solaris system from 11.3 to 11.4, you may find that things don’t go well if you have configured the ARP property on the loopback interface (regardless of value, on or off). This is a little surprising as the ARP property for a loopback interface does not exist in Solaris 11.4. This might be a common…
Read More →I recently used ZFS snapshots and ZFS send/recv to move a non-global zone from one host to another, as I’ve done hundreds of times, and was quite surprised to see that some data was missing. Spoiler alert: Solaris didn’t lose any data, but something non-obvious was happening. For a non-global zone that I need…

Previously, the LDAP client in Solaris was looking for *.db files containing your LDAP server’s certificate, typically in the /var/ldap directory. In 11.4, more of openldap seems to be integrated…
Read More →This configuration focuses on a working setup where the DHCP server updates the DNS server with dynamically assigned addresses. There are other production considerations, including the best location for directories and logging, that are not addressed here. About Our Setup We will configure the DHCP server and DNS server on the same host. Here are…
Read More →We needed to create a lab environment that could spin up several Solaris zones at one time in a somewhat isolated environment. To do this, we created a kernel zone which would contain non-global zones in their own isolated subnet. We wanted these non-global zones to be able to connect to resources outside of the…
Read More →You might find yourself needing to run a Solaris 11 host with non-global zones running as a VMWare guest for a number of reasons. Generally, I would run a Solaris zone host on bare metal for production, but it can work under VMWare as well in more limited deployment. Still, this might be more common…
Read More →In an environment running the ISC DHCP server and BIND DNS server, DHCP leases should update the DNS server dynamically with the name and IP address of the client assigned the lease. This was not working for my Solaris 11.3 clients in my lab. I tracked this down to the Solaris DHCP client not sending…
Read More →Overview This post will walk through setting up an OpenLDAP server to provide LDAP name services for Solaris clients. Having previously gone through this process with a different LDAP server, I was interested in what seems to be better support for using OpenLDAP for this purpose in Solaris 11.4. There doesn’t seem to be a…
