Installing Configuration Elements into Storage Pools and Disk Groups

Installing Configuration Elements into Storage Pools and Disk
Groups
If you specify a template set, storage pool definition or a storage pool set definition when creating a
storage pool, the required templates and capabilities are automatically associated with the storage
pool and with its disk group. (See “Creating a Storage Pool” on page 36 for details.)
A storage pool's selfsufficient policy governs whether configuration elements can be
installed automatically from the Configuration Database as required. If the policy is set to host,
elements are available to the pool from the Configuration Database, from the disk group and from
the pool itself. If the policy is set to diskgroup, the pool can install additional elements from the
disk group, but not from the Configuration Database. A policy value of pool means that only
elements that are installed in the pool can be used. If required, you can use the vxtemplate
command to install templates, capabilities and template sets from the Configuration Database into
disk groups and pools.
Template sets are convenient for installing many capabilities and templates in a single operation.
The following example shows how to install all the capabilities and templates from the template
set, DataMirroring, into a storage pool, mypool, and its disk group, mydg:
# vxtemplate -g mydg -p mypool install template_set=DataMirroring
This is equivalent to using this (very long) command:
# vxtemplate -r -g mydg -p mypool install \
template=DataMirroring,ArrayProductId,\
ConfineLogsToSimilarStorage,ConfineMirrorsToSimilarStorage,\
DCOLogMirroring,InstantSnapshottable,LogsOnSeparateComponents,\
MirrorsOnSeparateComponents
Listing and Printing Configuration Elements
Use the following command to list the templates and capabilities that are associated with a
specified disk group and/or storage pool.
# vxtemplate [-g diskgroup] [-p pool] list
This command displays results similar to the following.
