voldiskadd(8) — Maintenance
NAME
voldiskadd − Add a disk for use with the Logical Storage Manager
SYNOPSIS
/sbin/voldiskadd [dd[l]n[nnn][p]]
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 disklabel should exist on the disk before using the voldiskadd command.
The voldiskadd utility is an interactive command that prompts the user for information about disk setup. All courses of action that do not involve clear failure conditions require the user to answer prompts, with defaults supplied as appropriate. Help is available at every prompt. Entering ? in response to a prompt displays a context-sensitive help message.
Disk setup includes changing the disk’s disklabel to include LSM disklabel tags, the size of the LSM private region, and the size of the LSM public region.
An argument passed to the voldiskadd command directs the command to the disk being added. The argument is a physical address, comprised of the following elements: the device mnemonic dd (rz for SCSI devices, re for SCSI RAID devices, and ra for MSCP devices), l for the LUN number for SCSI RAID devices, the unit number (n), and, optionally, the partition identifier (p). The partition identifier is a lowercase letter in the range a to h.
The voldiskadd utility supports the following general classes of actions:
•"Initialization of a disk with reserved regions and partitions."
Initialization of the disk will be performed by calling voldisksetup.
•"Adding a disk to an existing disk group."
This operation can be performed independently of the initialization of the disk drive, and will add the disk to the group so that it’s storage will be added to the free space pool in that disk group. The volassist utility may subsequently allocate from that free space.
•"Creation of new disk groups in which to import a new disk."
If disks are added that are required to be put into a disk group that does not exist, then the option of creating the disk group will be offered.
