NAME

       voldiskadd - Adds one or more disks for use with the Logical Storage Manager

SYNOPSIS

       /usr/sbin/voldiskadd disk-address-list

DESCRIPTION

       The  voldiskadd	utility  sets up new disks that are added to the system after the initial system installation and configures the disks for
       use by the Logical Storage Manager. A valid disk label must exist on the disk before using the voldiskadd utility.

       One or more disks may be specified using a disk-address-list. Disk addresses in the list have the form dskn (for the entire disk) or  dsknp
       (for a specific partition). When specifying multiple disks, use a space between entries. Disk address names relate directly to device names
       in the /dev/disk directory.

       For example, here are some valid voldiskadd disk-address-list specifications: # voldiskadd dsk1 # voldiskadd dsk2 dsk3a

       The file, /etc/vol/disks.exclude, may be used to exclude disks from use by voldiskadd. Each line of the file specifies the name of  a  disk
       to exclude (for example, dsk5).

       The  voldiskadd	utility  prompts  the user for a disk group name and disk media name for the disks. If a new disk group name is specified,
       that disk group is created for the new disks. If no disk group name is specified, the disks are left as unassigned  replacement	disks  for
       future  use. If an existing disk group name is specified, the user is prompted for whether the disks should be designated as spares for the
       disk group.

       If a disk is found to already contain non-Logical Storage Manager partitioning, the user is asked whether the disk should be  encapsulated.
       Encapsulation turns each partition of the disk into a volume. A disk should be encapsulated if it contains file systems or data that should
       not be overwritten. If encapsulation is not desired for a disk, the disk can be initialized as a new disk for use by  the  Logical  Storage
       Manager. For new disks, all space on the disk becomes free space in the disk's disk group.

       Context-sensitive  help	is  available  at every prompt by typing ?. Also, a list option can be used to get information on available target
       disks for an operation.

       The voldiskadd utility supports the following general classes of actions: Initializing a disk with reserved regions and partitions.

	      Disk initialization is performed by calling voldisksetup command.  Adding a disk to an existing disk group.

	      This operation can be performed independently of the initialization of the disk drive to add  a  disk's  storage	space  to  a  disk
	      group's  free  space pool. The volassist command may subsequently allocate from that free space. The disk can also be added as a hot
	      spare device.  Creating new disk groups in which to import new disks.

	      If no disk group exists for importing disks, the option of creating the disk group is offered.  Encapsulating disks that have exist-
	      ing contents.

	      This  is	the default action for disks that do not have a valid, existing Logical Storage Manager private region, but that do have a
	      disk label. Encapsulation is performed by calling volencap.  Reconnecting a drive that was temporarily inaccessible.

	      This situation is detected automatically, by noting that the specified drive has a disk ID that matches a disk media record with	no
	      currently  associated physical disk. After reconnection, any stale plexes referring the disk are reattached, and any stopped volumes
	      referring the disk are restarted. This reattach action is performed by calling the volrecover script.

ERRORS

       You may receive the following messages when using the voldiskadd command:

       Initialization of disk device special-device failed.  Error: special-device or an overlapping partition is open.

       This message indicates that the partition you specified or an overlapping partition on the disk is actively in use. The partition could	be
       a mounted UFS or AdvFS filesystem, initialized as an LSM disk or used as a swap device.

       special-device is marked in use for fstype in the disklabel.  If you continue with the operation you can possibly destroy existing data.

       Would you like to continue?? [y,n,q,?] (default: n)

       This  message  indicates that the fstype of a partition or an overlapping partition is set in the disk label. The voldiskadd command prints
       this message to warn that a disk partition may have valid data which could be destroyed.

       If you are sure that the disk partition does not have valid data and that the partition can be added to LSM, you  can  ignore  the  warning
       message by entering y at the prompt. The voldiskadd command will proceed to initialize the disk partition and add it to LSM.
