NAME

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

SYNOPSIS

/usr/sbin/voldiskadd disk-address-list

DESCRIPTION

The voldiskadd interactive 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, the following are 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 you for a disk group name and disk media name for the disks. If you specify a new disk group name, that disk group is created for the new disks. If you do not specify a disk group name, the disks are left as unassigned replacement disks for future use. If you specify an existing disk group name, you are 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, you are asked whether the disk should be encapsulated. Encapsulation turns each partition of the disk into a volume. Encapsulate a disk if it contains file systems or data that should not be overwritten. If you do not want to encapsulate the disk, you can initialize it 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 ?. You can also enter list 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. You can add disks to disk groups independently of initializing disks, 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. You can also add the disk as a hot spare device. · Creating new disk groups in which to add new disks. If no disk group exists for adding disks, you can create a new disk group. · Encapsulating disks that have existing 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 that 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.
