Managing logical partitions
You can manage the configuration of your logical partitions using the Hardware Management Console (HMC). The HMC allows you to adjust the hardware resources that are used by each logical partition.
- Activating a logical partition
You must activate a logical partition before you can use the logical partition. When you use the Hardware Management Console (HMC), you can activate a logical partition based on its current configuration or you can activate a logical partition by activating a partition profile. - Activating a system profile
You can activate many logical partitions at a time by using the Hardware Management Console (HMC) to activate a system profile. A system profile is an ordered list of partition profiles. When you activate a system profile, the managed system attempts to activate the partition profiles in the system profile in the order in which the partition profiles are listed. - Shutting down and restarting logical partitions
You can shut down and restart logical partitions running on systems that are managed by a Hardware Management Console (HMC). - Partition time power-on
If the operating system on a logical partition is scheduled to start at a specified time, the server starts automatically if the server is not already powered on. The management partition on an Integrated Virtualization Manager (IVM) managed system or the hosting partition on a Virtual Partition Manager managed system also start automatically if the partitions are not already running. However, other logical partitions are not started automatically at the specified time, even if the logical partitions are set to auto start at system power-on. - Managing partition profiles for logical partitions
You can manage the partition profiles for your logical partitions using the Hardware Management Console (HMC). You can change the resource specifications stored in your partition profiles as your needs change. - Managing system profiles
You can manage the system profiles on your managed system using the Hardware Management Console (HMC). You can change the logical partitions and partition profiles specified within the system profiles as the logical partitions change on your managed system. - Managing the resources of a shutdown logical partition
You can use the Hardware Management Console (HMC) command-line interface to manage the resources of a shutdown logical partition. - Managing logical partition resources dynamically
You can use the Hardware Management Console (HMC) to add, remove, or move processor, memory, and I/O resources between running logical partitions without restarting the logical partitions or the managed system. - Managing virtual resources for Virtual I/O Server logical partitions using the HMC
Use the Hardware Management Console (HMC) to manage virtual storage that is associated with Virtual I/O Server logical partitions. - Managing the memory configuration of a logical partition
You can use the Hardware Management Console (HMC) to change the memory configuration of a logical partition. For example, you can change the Virtual I/O Server logical partitions that are assigned to a logical partition that uses shared memory, change the memory mode of a logical partition, and dynamically add and remove dedicated or shared memory to and from a logical partition. - Obtaining additional WWPNs for the server
When all of the worldwide port names (WWPNs) on the server are used, you can add more WWPNs to the server using the Hardware Management Console (HMC). Adding WWPNs allows you to create additional virtual Fibre Channel adapters on client logical partitions that use virtual resources provided by the Virtual I/O Server. - Setting partition-availability priorities for your managed system
To avoid shutting down mission-critical workloads when your server firmware deconfigures a failing processor, you can use the Hardware Management Console (HMC) to set partition-availablity priorities for the logical partitions on your managed system. A logical partition with a failing processor can acquire a replacement processor from logical partitions with a lower partition-availability priority. The acquisition of a replacement processor allows the logical partition with the higher partition-availability priority to continue running after a processor failure. - Installing new hardware for IBM i logical partitions
You can install an I/O adapter (IOA) for an IBM i logical partition. - Backing up and recovering data
It is crucial that you back up your data because you never know when you might need to do a server recovery. Save everything in your system as often as possible. You might not be prepared to recover from a site loss or certain types of disk failures if you do not regularly save everything. - Managing logical partitions that use IBM i resources
You can manage logical partitions that use IBM i virtual I/O resources to help maximize utilization of the physical hardware and simplify the backup procedure for your managed system. - Synchronizing the hypervisor and Service Processor time-of-day clocks to Time Reference Partition
You can ensure that the time-of-day clocks used by the hypervisor and Service Processor are accurate through the usage of one or more Time Reference Partitions (TRP). Whenever the time-of-day changes in the TRP, the hypervisor and the service processors time-of-day are updated to match the time that is specified by the TRP. The time of the TRP can be changed manually or can be managed by using the Network Time Protocol (NTP) support. NTP can be used to automatically ensure consistent time-of-day across multiple servers. When you designate a logical partition as a TRP, you must choose a logical partition that cannot be migrated to another server such as a Virtual I/O Server (VIOS) partition. More than one TRP can be specified per server and the longest running TRP is recognized as the TRP of the system.
