LDoms (Logical Domains) are a virtualization technology in Solaris that allow you to create multiple virtual machines on a single physical server.

• LDoms allow you to partition a single physical server into multiple virtual machines, each with its own operating system instance.

• Each LDoms domain has its own resources such as CPU, memory, and storage.

• LDoms provide flexibility and resource isolation for running multiple app...read more

There are 7 boot phases in Solaris operating system.

• There are 7 boot phases in Solaris: firmware, boot program, kernel initialization, system identification, system initialization, system configuration, and user-level initialization.

• Each boot phase plays a crucial role in the startup process of the Solaris operating system.

• Understanding the boot phases is important for troubleshooting and optimizing system performance.

Work run level is a specific operating state in Solaris that determines which services and processes are running.

• Work run level is a specific operating state in Solaris that determines which services and processes are running.

• It is represented by a number from 0 to 6, with each level having a different set of services and processes configured to run.

• For example, run level 3 is typically used for multi-user mode with ne...read more

OS installation is the process of setting up an operating system on a computer or server.

• OS installation involves booting from installation media such as a CD or USB drive.

• The user follows prompts to select language, disk partitioning, and other settings.

• Once installation is complete, the OS is ready to be used.

• Examples include installing Windows, Linux, or Solaris on a computer.

LDoms (Logical Domains) are a virtualization technology in Solaris that allows multiple virtual machines to run on a single physical server.

• LDoms provide a way to partition a single physical server into multiple virtual machines, each with its own operating system instance.

• LDoms allow for better resource utilization and isolation between virtual machines.

• LDoms can be used to consolidate workloads, improve system flexib...read more

To configure primary ldom, you need to create a primary domain and assign resources to it.

• Create a primary domain using the ldm create command

• Assign resources to the primary domain using the ldm add-vcpu, ldm add-memory, and ldm add-vnet commands

• Verify the configuration using the ldm list command

LDoms are logical domains in Solaris that provide virtualization capabilities.

• LDoms allow you to create multiple virtual machines on a single physical server.

• Each LDoms instance has its own resources and can run its own operating system.

• LDoms provide flexibility in managing resources and isolating workloads.

• Common services in LDoms include networking, storage, and virtual CPUs.

Troubleshooting user login issues in Solaris involves checking user permissions, password reset, and system logs.

• Check user permissions to ensure they have the necessary access rights

• Reset user password if necessary

• Review system logs for any error messages related to user login

To check the wwn number, you can use commands like 'luxadm', 'prtconf', 'cfgadm', or 'format'.

• Use 'luxadm display' command to check wwn number of FC devices

• Use 'prtconf -vp' command to check wwn number of HBA

• Use 'cfgadm -al' command to check wwn number of connected devices

• Use 'format' command to check wwn number of disks

To troubleshoot a non-working file system, check for disk space, file system errors, and system logs.

• Check disk space to ensure there is enough storage available

• Check for file system errors using fsck command

• Review system logs for any error messages related to the file system

• Verify file system mount points and permissions

The number of daemon zones that can work on Solaris depends on the system resources and configuration.

• The number of daemon zones that can work on Solaris is not fixed and can vary based on system resources.

• Daemon zones are lightweight virtual environments that can run applications independently.

• The number of daemon zones that can work simultaneously is limited by factors such as CPU, memory, and disk space.

• It is import...read more
