3.1.16 Deleting a System Board From a Building Block Configuration


3.1.16 Deleting a System Board From a Building Block Configuration
Use the deleteboard command to delete a system board (PSB<BB>) that represents a building block (BB) or reserve the deletion of one from a physical partition. The deleted PSB (BB) is assigned to the system board pool, which does not belong to any physical partition.

Before executing this command, check the physical partition status (showpparstatus command), PSB (BB) status (showboards command), and status of device usage on the PSB (BB) (showfru command) by using the respective commands.
Note - A user account that has the platadm or pparadm privilege can execute the deleteboard command.
XSCF> deleteboard [-f] [-c disconnect]
[-m unbind={none|resource|shutdown}]
psb [psb...]
XSCF> deleteboard [-f] -c unassign psb [psb...]
XSCF> deleteboard [-f] -c reserve psb [psb...]
  1. -c disconnect option

    This option releases a PSB (BB) operating in a physical partition from the physical partition configuration and puts it in the assigned state. To incorporate the PSB (BB) into the physical partition again, restart the physical partition or execute the addboard command while the system board remains assigned to the physical partition configuration. If the -c unassign or -c reserve option is omitted, the -c disconnect option is assumed specified.
  2. -c unassign option

    This option unassigns a PSB (BB) from a physical partition and puts it in the system board pool state. The PSB (BB) in the system board pool state can be incorporated into or assigned to another physical partition.
  3. -c reserve option

    This option reserves the unassignment of a PSB (BB) from a physical partition. After being reserved for unassignment, the PSB (BB) is unassigned based on PPAR configuration information at the power-off time of the specified physical partition, and put in the system board pool state.
  4. -m unbind={none|resource|shutdown} option

    This option sets the action to take when a logical domain that uses resources on a PSB (BB) to be released is moved to a PSB (BB) that is not released and the destination has insufficient resources.
Setting Description
none Secures no resources at the destination. If the destination has insufficient resources, execution of the deleteboard command fails.
If the logical domain configuration information for the physical partition is factory-default, the -m unbind=none option cannot be specified.
If an error occurs, you must remove the CPU core or memory from the logical domain by using the virtual DR function of Oracle VM Server for SPARC.
resource Secures resources at the destination by reducing either the resources of the logical domain that needs resources moved or the resources of another logical domain. However, it does not shut down a logical domain to secure resources at the destination. In addition, on XCP 2240 or later with Oracle VM Server for SPARC 3.2 or later, it automatically deletes the physical I/O.
shutdown Secures resources at the destination by reducing either the resources of the logical domain that needs resources moved or the resources of another logical domain. In addition, it shuts down a logical domain to secure resources at the destination.
  1. psb
    Specify a system board number.
  2. -f option

    This option forcibly releases a PSB (BB).
Note - If the deleteboard command has the -f option specified to forcibly delete a PSB (BB) from a physical partition, a serious problem may occur in a cpu-bound process or a process accessing a device. Therefore, we recommend not using the -f option in normal operation. If you specify the -f option, be sure to check the status of the physical partition and business processes before and after executing the deleteboard command.
Note - Before using the deleteboard command with the -c disconnect or -c unassign option specified in order to delete a PSB (BB) while the physical partition is operating, do the following: use the setpparmode command to enable the PPAR DR function for the physical partition from which to delete the PSB (BB), and restart the physical partition. You cannot delete a PSB (BB) from a physical partition with the PPAR DR function disabled by specifying the -c disconnect or -c unassign option while the physical partition is operating.
Note - If a CPU Activation violation has occurred in a physical partition, the deleteboard command cannot be executed for dynamic reconfiguration. Eliminate the CPU Activation violation, and then execute the deleteboard command to perform dynamic reconfiguration.
Note - If dynamic reconfiguration processing by the deleteboard command fails, the target PSB (BB) cannot be returned back to its state before this processing. Identify the cause from the error message output by the deleteboard command and the Oracle Solaris message, and take appropriate action. However, you may need to power off or restart the physical partition, depending on the error that occurred.
The following example sets physical system boards (PSB) 00-0, 01-0, 02-0, and 03-0 to the system board pool state.
XSCF> deleteboard -c unassign 00-0 01-0 02-0 03-0
The following example reserves the release of PSBs 00-0, 01-0, 02-0, and 03-0.
XSCF> deleteboard -c reserve 00-0 01-0 02-0 03-0
