NAME
volsave - Saves a Logical Storage Manager (LSM) configuration SYNOPSIS
/usr/sbin/volsave [-d dir] OPTIONS
Directs the backup information to the directory specified by dir. This directory must not already exist. DESCRIPTION
You can save the LSM configuration records for a disk group by saving the output of the volprint(8) utility in a description file that the volmake(8) utility can use. The volsave command provides an easy way to save this configuration information for all disk groups. In addi- tion, volsave saves a list of the disks that are under LSM control and their attributes. The LSM configuration can be restored using the volrestore command. The volsave command creates an LSM description set that consists of a header file and other files containing information about the LSM con- figuration (allvol.DF, voldisk.list, and volboot). Refer to the FILES section for details on the contents of these files. By default, the description set is saved to a timestamped directory in /usr/var/lsm/db (for example, /usr/var/lsm/db/lsm.19970727131520.skylark). The -d option can be used with volsave to specify a particular directory for the saved configuration. In this case, the -d option must also be used with volrestore when restoring the configuration. ERRORS
You may receive the following error message when using the -d dir option with the volsave command: Directory dir already exists This message indicates that the directory you specified is already in use. The LSM configuration can only be saved to a directory that does not yet exist. You can specify a new directory name, or enter the volsave command without the -d option and let volsave create a new, timestamped directory in /usr/var/lsm/db. FILES
Default directory containing timestamped subdirectories with LSM description sets. A volmake description file for all volumes, plexes, and subdisks in a disk group. The volsave command creates a separate subdirectory and description file for each disk group on the system. A description of the disks. This file is the output of the voldisk list command. The contents of the /etc/vol/volboot file. A header file for the description set, containing a checksum, a magic number, the date of the file's creation, and the version of the volsave command.

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. FILES
