DESCRIPTION
  The voldctl utility manages some aspects of the state of the volume
  configuration daemon, vold, and manages configuration aspects related to
  bootstrapping the rootdg disk group configuration.

  A key part of the state of vold and of bootstrapping the rootdg disk group
  is the /etc/vol/volboot file. This file contains a host ID, which is
  usually the host name, that LSM uses to establish ownership of physical
  disks. This host ID is used to ensure that two or more hosts that can
  access disks on a shared SCSI bus will not interfere with each other in
  their use of those disks. This host ID is also important in the generation
  of some unique ID strings that are used internally by the Logical Storage
  Manager for stamping disks and disk groups.

  The /etc/vol/volboot file may also contain a list of disks to scan in
  search of the rootdg disk group. This list is only needed if the
  autoconfiguration functionality of LSM is disabled (see vold(8) for
  details). At least one disk in the list must be both readable and a part of
  the rootdg disk group, or the Logical Storage Manager will not be able to
  start up correctly.

  The vold daemon operates in one of three modes: enabled, disabled, or
  booted.  The enabled state is the normal operating state. Most
  configuration operations are allowed in the enabled state. Entering the
  enabled state imports all disk groups, and begins the management of device
  nodes stored in the /dev/vol and /dev/rvol directories.

  In the disabled state, vold does not retain configuration information for
  the imported disk groups, and does not maintain the volume device
  directories. Most operations are disallowed in the disabled state. Certain
  failures, most commonly the loss of all disks or configuration copies in
  the rootdg disk group, will cause vold to enter the disabled state
  automatically.

  The booted state is entered as part of normal system startup, prior to
  checking the root file system (see fsck(1)). Entering the booted mode
  imports the rootdg disk group, and then waits for a request to enter the
  enabled mode. The volume device node directories are not maintained in
  booted mode, because it may not be possible to write to the root file
  system.

KEYWORDS
  The action performed by voldctl depends upon the keyword specified as the
  first operand. Supported keywords are:

  init
      Reinitializes the /etc/vol/volboot file with a new host ID (which is
      usually the host name), and an empty list of disks. If a hostid operand
      is specified, this string is used; otherwise, a default host ID is
      used. On systems with a hardware-defined system ID, the default host ID
      might be derived from this hardware ID.

  hostid
      Changes the host ID, which is usually the host name, in the
      /etc/vol/volboot file and on all disks in disk groups currently
      imported on this machine. It may be desirable to change the Logical
      Storage Manager host ID for your machine if you are also changing the
      network node name of your machine.

      If some disks are inaccessible at the time of a hostid operation, it
      may be necessary to use the voldisk clearimport operation to clear out
      the old host ID on those disks when they become reaccessible.
      Otherwise, you may not be able to re-add those disks to their disk
      groups.


				       Note

	 Take care when using this command. If the system crashes before the
	 hostid operation completes, some disk groups may not reimport
	 automatically.

  add disk
      Adds to the list of disks in the /etc/vol/volboot file. Disks are
      specified based on their disk access name. This name identifies the
      physical address of the disk. For example, to add disk dsk3c you might
      use the command:
	   /sbin/voldctl add disk dsk3c

      If there is a disk access record in the rootdg configuration for the
      named disk, configuration parameters are taken from that record.
      Otherwise, it may be necessary to specify some attributes to voldctl
      add disk.

  rm disk
      Removes one or more disks from the /etc/vol/volboot file. Disks are
      specified based on the name used in the corresponding voldctl add disk
      operation.

  list
      Lists the contents of the /etc/vol/volboot file. This list includes the
      host ID (which is usually the host name), some sequence numbers, and
      the list of disks and disk attributes stored in the /etc/vol/volboot
      file.

  enable
      Requests that vold enter enabled mode, import all disk groups, and
      rebuild the volume device node directories. This operation can be used
      even if vold is already in enabled mode. The primary purpose for using
      this operation when in enabled mode is to rebuild the volume device
      nodes. This operation will also cause vold to scan for any disks that
      were newly added since vold was last started. In this manner, disks can
      be dynamically configured to the system and then recognized by the
      Logical Storage Manager.

      If this operation fails, voldctl exits with the appropriate error
      status and displays an error message.

  disable
      Requests that vold enter disabled mode. This may be necessary to
      perform some maintenance operations.  This does not disable any
      configuration state loaded into the kernel. It only prevents further
      configuration changes to loaded disk groups until vold is re-enabled.

  stop
      Requests that vold exit. This may be necessary to reset the Logical
      Storage Manager, such as using the -r reset option to vold. This does
      not disable any configuration state loaded into the kernel. It only
      affects the ability to make configuration changes until vold is
      restarted. If the -k option is used vold will be stopped by sending it
      a SIGKILL signal. The command will delay for up to 1 second to verify
      that vold has exited. After 1 second if vold has not exited an error
      will be returned.

  mode
      Prints the current operating mode of vold.  The output format is:

      mode: operating_mode

      where operating_mode is either enabled, disabled, booted, or not-
      running.

  license [init]
      With an argument of init, requests that vold re-read any persistently
      stored license information. If licenses have expired, this may cause
      some features to become unavailable. If new licenses have been added,
      this will make the features defined in those licenses available.

      With no arguments, voldctl license prints the list of features which
      are currently available based on known licensing information.
