How to create an I/O domain
An I/O domain has a direct access to the underlying hardware devices. It is used generally in a case where you want performance improvements avoiding the overheads to access the hardware indirectly through control domain. You can create I/O domain is 2 ways: 1. Using the entire PCIe BUS 2. Using a PCIe end point device Creating I/O domains using PCIe buses Now as shown in ther digram we can assign a complete PCI bus(pci_1) to the I/O domain assuming there are no disk or network devices on … [Read more...] about How to create an I/O domain
How to reset LDOM configuration to factory default
The factory-default configuration is the configuration when you first time install the Oracle VM Server for SPARC software on to a fresh Solaris OS. To set the physical server to factory-default configuration : 1. Remove all the guest LDOMs 2. Remove all the saved LDOM configurations 3. Restore the factory default configuration a. from command line b. from service processor Stop all the ldoms, unbind and delete them First step is to stop all the domains, unbind them and remove … [Read more...] about How to reset LDOM configuration to factory default
ZFS Tutorials : Creating ZFS snapshot and clones
ZFS snapshots zfs snapshot is a read-only copy of zfs file system or volume. They consume no extra space in the zfs pool and can be created instantly. They can be used to save a state of file system at particular point of time and can later be rolled back to exactly same state. You can also extract some of the files from the snapshot if required and not doing a complete roll back. Let us take a look at the steps involved in creating a snapshot of zfs file system. Creating and destroying … [Read more...] about ZFS Tutorials : Creating ZFS snapshot and clones
How to configure a domain on Mx000 series server
M series servers can be configured into domains to have a better utilization of the server resources. There are 2 types of domains that can be created. 1. Static domain - Add and remove boards in an inactive domain 2. Dynamic domain - Add and remove boards in an active domain using solaris 10 DR (dynamic reconfiguration) operation. We will be creating a static domain in this example. Before start creating the domain let us see the basic terminologies and their … [Read more...] about How to configure a domain on Mx000 series server
