NAME
metassist - automated volume creation utility to support Solaris Volume Manager
SYNOPSIS
metassist -V
metassist -?
metassist create [-v n] [-c] -F config_file
metassist create [-v n] [-c | -d] -F request_file
metassist create [-v n] [-c | -d] [-f] [-n name] [-p datapaths] [-r redundancy] [-a available [,available,...]] [-u unavailable [,unavail-
able,...]] -s setname -S size
metassist create -?
The metassist command provides assistance, through automation, with common Solaris Volume Manager tasks.
SUBCOMMANDS
The following subcommands are supported:
create The create subcommand creates one or more Solaris Volume Manager volumes. You can specify this request on the command line
or in a file specified on the command line.
If you create a volume using the command line, you can specify the characteristics of the volume in terms of the desired
quality of service it will provide - its size, the number of redundant copies of the data it contains, the number of data
paths by which it is accessible, and whether faulty components are replaced automatically. The diskset in which the volume
will reside and the volume's size must be specified on the command line in this form of the command.
If you create a volume using a request in a file, you can specify the characteristics of the volume in terms of the quality
of service they provide, as on the command line. Alternatively, the file can specify the types and component parts of the
volume, (for example, mirrors, stripes, concatenations, and their component slices). The file may also specify volumes
partly in terms of their types and partly in terms of their component parts, and may specify the characteristics of more
than one volume. All volumes specified in a file must reside in the same diskset, whose name must be specified in the file.
If you specify the -c or -d option on the command line, the command runs without creating an actual volume or volumes.
Instead, it outputs either a a Bourne shell command script (-c option) or a volume configuration (-d option). The command
script, when run, creates the specified volume or volumes. The volume configuration specifies the volume or volumes in com-
plete detail, naming all their components.
The input file given on the command line can take one of the following forms:
o a volume request, which specifies a request for a volume with explicit attributes and components, or matching a given
quality of service
o a volume configuration, produced by a previous execution of the command
The following option is mandatory if you specify a volume request or volume configuration in a file:
-F config_file| request_file
Specify the volume request or volume configuration file to process. If config_file or request_file is -, it is read from standard
input.
The -d option cannot be specified when inputfile is a volume configuration file.
The following options are mandatory if you specify a volume request on the command line:
-s set
Specify the disk set to use when creating volumes. All the volumes and hot spare pools are created in this disk set. If necessary,
disks are moved into the diskset for use in the volumes and hot spare pools. If the diskset doesn't exist the command creates it. This
option is required. metassist works entirely within a named disk set. Use of the local, or unnamed disk set, is not allowed.
-S size
Specify the size of the volume to be created. The size argument consists of a numeric value (a decimal can be specified) followed by
KB, MB, GB, or TB, indicating kilobytes, megabytes, gigabytes, or terabytes, respectively.
Case is ignored when interpreting this option. This option is required.
The following options are optional command line parameters:
-a device1,device2,...
Explicitly specify the devices that can be used in the creation of this volume. Named devices may be controllers or disks. Only used
when specifying a volume on the command line.
-c
Output the command script that would implement the specified or generated volume configuration. The command script is not run, and
processing stops at this stage.
-d
Output the volume configuration that satisfies the specified or generated volume request. No command script is generated or executed,
and processing stops at this stage.
-f
Specify whether the volume should support automatic component replacement after a fault. If this option is specified, a mirror is cre-
ated and its submirrors are associated with a hot spare.
-n name
Specify the name of the new volume. See metainit(1M) for naming guidelines.
-p n
Specify the number of required paths to the storage volume. The value of n cannot be greater than the number of different physical
paths and logical paths to attached storage. Only used when specifying a volume on the command line.
-r n
Specify the redundancy level (0-4) of the data. The default is 0. Only used when specifying a volume on the command line. If redundancy
is 0, a stripe is created. If redundancy is 1 or greater, a mirror with this number of submirrors is created. In this case, the volume
can suffer a disk failure on n-1 copies without data loss. With the use of hot spares (see the -f option), a volume can suffer a disk
failure on n+hsps-1 volumes without data loss, assuming non-concurrent failures.
-u device1,device2,...
Explicitly specify devices to exclude in the creation of this volume. Named devices can be controllers or disks. You can use this
option alone, or to exclude some of the devices listed as available with the -a option, Only used when specifying a volume on the com-
mand line.
-v value
Specify the level of verbosity. Values from 0 to 2 are available, with higher numbers specifying more verbose output when the command
is run. -v 0 indicates silent output, except for errors or other critical messages. The default level is 1.
-V
Display program version information.
-?
Display help information. This option can follow a subcommand for subcommand-specific help.
Example 1: Creating a Mirror
The following example creates a two-way, 36Gb mirror on available devices from controller 1 and controller 2. It places the volume in
diskset mirrorset.
# metassist create -r 2 -a c1,c2 -s mirrorset -S 36G
Example 2: Creating a Mirror with Additional Fault Tolerance
The following example creates a two-way, 36Gb mirror on available devices from controller 1 and controller 2. It provides additional fault
tolerance in the form of a hot spare. It places the volume in diskset mirrorset.
# metassist create -f -r 2 -a c1,c2 -s mirrorset -S 36GB
Example 3: Creating a Three-way Mirror and Excluding Devices
The following example creates a three-way, 180Gb mirror from storage devices on controller 1 or controller 2. It excludes the disks c1t2d0
and c2t2d1 from the volume. It places the volume in diskset mirrorset.
metassist create -r 3 -a c1,c2 -u c1t2d0, c2t2d1
-s mirrorset -S 180GB
Example 4: Determining and Implementing a Configuration
The following example determines and implements a configuration satisfying the request specified in a request file:
# metassist create -F request.xml
Example 5: Determining a Configuration and Saving It in a volume-config File
The following example determines a configuration which satisfies the given request. It saves the configuration in a volume-config file
without implementing it:
# metassist create -d -F request.xml > volume-config
Example 6: Determining a Configuration and Saving It in a Shell Script
The following example determines a configuration which satisfies the given request. It saves the configuration in a shell script without
implementing it:
# metassist create -c -F request.xml > setupvols.sh
Example 7: Implementing the Given volume-config
The following example implements the given volume-config:
# metassist create -F config.xml
Example 8: Converting the Given volume-config to a Shell Script
The following example converts the given volume-config to a shell script that you can run later:
# metassist create -c -F config.xml > setupvols.sh
The following exit values are returned:
0 Successful completion.
>0 An error occurred.

The quality of service arguments are mutually exclusive with the -F inputfile argument.
When specifying a request file or quality of service arguments on the command line, the /etc/default/metassist.xml file is read for global
and per-disk set defaults.
Characteristics of this file are specified in the DTD, in /usr/share/lib/xml/dtd/volume-defaults.dtd.
Characteristics of the XML request file are specified in the DTD, in /usr/share/lib/xml/dtd/volume-request.dtd.
Characteristics of the XML configuration file are specified in the DTD, in /usr/share/lib/xml/dtd/volume-config.dtd.
This command must be run as root.
This command requires a functional Solaris Volume Manager configuration before it runs.
