DRMGR(8)

NAME
drmgr - Manage DLPAR resources of a virtualized ppc64 system.

SYNOPSIS
drmgr [-d detail_level] [-w minutes] [-C|--capabilities] [-h|--help] drmgr -c {pci | cpu | mem | port | slot | phb} drmgr -c pci -s slot_location_code {-i | -a | -r | -R } [-I] drmgr -c cpu {-a | -r} {-q quantity | -s {drc_index | drc_name}} drmgr -c mem {-a | -r} {-q quantity | -s {drc_index | drc_name}} drmgr -c {port | slot | phb} {-a | -r} -s {drc_index | drc_name}

DESCRIPTION
drmgr is a utility for managing logical and physical hot plug capable resources of a PowerVM LPAR or QEMU/KVM pSeries virtual machine via Dynamic Logical Partitioning (DLPAR) operations. Outside of hot plugging a physical PCI I/O slot the drmgr utility is intended to be invoked remotely by a Hardware Management Console (HMC), or by a local monitoring daemon in response to a hotplug interrupt from the controlling hypervisor.

Unless directed by IBM support or performing a PCI hotplug operation use caution invoking drmgr from the commandline as it can result in inconsistent state between the LPAR and management system.

OPTIONS

-d detail_level
    Set logging verbosity level.

-w timeout
    Specify a timeout in minutes to wait on acquiring dynamic resource lock.

-C, --capabilities
    Display DLPAR capabilities of the logical partition.

-c drc_type
    Dynamic reconfiguration connector type to act upon from the following list: pci, cpu, mem, port, slot, phb.

  drmgr -c pci -s slot_location_code {-i | -a | -r | -R} [-I]
Add, remove, identify, or replace a physical PCI adapter.

-s slot_location_code
    The physical slot location code to act upon.

-i  Identify the specified slot_location_code by turning on its visual indicator LED.

-R  Interactively replace the physical PCI adapter, with slot_location_code, by turning on the visual indicator LED to locate the physical slot, then powering down the slot so that the current card can be removed, and finally powering the slot back up after the new adapter has been inserted into the slot.

-r  Interactively remove a physical PCI adapter, from slot_location_code, by turning on the visual indicator LED to locate the physical slot, and then powering down the slot so that the current card can be removed.

-a  Interactively add a physical PCI adapter, to slot_location_code, by turning on the visual indicator LED to locate the physical slot, and then powering up the slot once the new adapter has been inserted into the slot.

-I  Do not perform the identify step during interactive add, remove, or replacement operations.

  drmgr -c cpu {-s {drc_index | drc_name} | -q count} {-a | -r}
Add or remove logical cpus from the system.

-s drc_index | drc_name
    The dynamic reconfiguration connector (DRC) index or name is used to identify one specific CPU on which to perform the requested DLPAR operation.

-q quantity
    Specify a quantity of CPUs on which to perform the requested DLPAR operation.

-a  Perform a DLPAR CPU(s) add operation.

-r  Perform a DLPAR CPU(s) remove operation.

  drmgr -c mem {-s {drc_index | drc_name} | -q count} {-a | -r}
Add or remove logical memory blocks (LMBs) from the system.

-s drc_index | drc_name
    The dynamic reconfiguration connector (DRC) index or name is used to identify one specific logical memory block (LMB) on which to perform the requested DLPAR operation.

-q quantity
    Specify a quantity of LMBs on which to perform the requested DLPAR operation.

-a  Perform a DLPAR LMB(s) add operation.

-r  Perform a DLPAR LMB(s) remove operation.

  drmgr -c {port | slot | phb} {-a | -r} -s {drc_index | drc_name}
Add or remove a logical IOA resource such as virtualized storage and network adapters, or a logical PCI Host Bus that physical PCI devices reside under including hotpluggable slots.

-s drc_index | drc_name
    The dynamic reconfiguration connector (DRC) index or name is used to identify the logical resource on which to perform the associated DLPAR operation.

-a  Perform a DLPAR add operation of the specified logical resource type.

-r  Perform a DLPAR remove operation of the specified logical resource type.
