2.7.1 Create a Cluster Template
This topic describes how to create a user-defined cluster template.
A cluster template is a named collection of file storage attribute settings defined at the cluster level. By using cluster templates, you can manage file storage attributes automatically and consistently across the Exascale cluster.
Exascale is automatically preconfigured with
cluster templates for each system-defined file type; for example,
DATAFILE
, ONLINELOG
,
CONTROLFILE
, and so on. Therefore, you can only create new user
templates at the cluster level.
To create a user-defined cluster template, use the ESCLI mktemplate
command with the --cluster
and --name
options and
specify the file storage attribute settings:
--media-type
: Specifies the physical media type that is used to store the file. Exascale uses this attribute to place the file in a storage pool that uses the specified media type. Possible values are:HC
: Identifies high capacity storage media, which uses hard disk drives (HDDs).EF
: Identifies extreme flash storage media, which uses flash devices.
--redundancy
: Specifies the number of data copies that are maintained. Possible values are:normal
: Maintains 2 mirrored copies of the file data.high
: Maintains 3 mirrored copies of the file data.
--content-type
: Specifies the type of content in the file. Exascale internally uses this attribute to place file extents on physically separate devices in a way that maximizes availability if failures occurs. Possible values are:DATA
RECO
The command syntax is:
@> mktemplate --cluster --name template-name --content-type content-type --media-type media-type --redundancy redundancy
