As an administrator, you are responsible for ensuring the optimal provisioning of storage to volumes.
In Veritas Operations Manager, you can use the Storage Provisioning Add-on for creating storage templates from existing storage objects such as volumes, disk groups, and file systems. It discovers the configuration details of the Veritas Volume Manager, Veritas File System, Storage Foundation for Windows, and New Technology File System (NTFS) objects to create a storage template with minimal user effort. You can use these templates to quickly and consistently provision storage configurations.
For information on using the Storage Provisioning Add-on, refer to the Veritas Storage Foundation™ Add-on for Storage Provisioning 4.0 User's Guide.
In Veritas Operations Manager, you can use the Storage Insight Add-on to define the tiers for LUNs. The Storage Insight Add-on lets you define the tiers for the LUNs based on one or more of the following parameters:
For information on using the Storage Insight Add-on, refer to the Veritas Operations Manager Storage Insight Add-on for Deep Array Discovery and Mapping 4.0 User's Guide.
When you define a storage provisioning template, you can select the tiers for the LUNs, which you have created using the Storage Insight Add-on.
This example explains how you can assign storage on tiers to volumes. This example considers LUNs from an HITACHI enclosure and an EMC CLARiiON enclosure. In this example, we use the following names:
Table: Names used in the example
This example does the following tasks as part of assigning the storage from the tiers to the volumes:
Define the tiers sample_tier1 and sample_tier2 for the enclosures HITACHI and EMC_CLAR.
Create the disk group sample_dg using the disks in the HITACHI and the EMC_CLAR enclosures.
Create a storage template sample_volstortemplate based on the existing volume sample_existing_vol.
Provision the storage from the tiers sample_tier1 and sample_tier2 to the two mirrors that are part of the sample_vol1 volume using the storage provisioning template sample_volstortemplate.
To define a tier for the LUN that is associated with the HITACHI enclosure
Repeat steps 1-4 for defining a tier for the LUN that is associated with the EMC_CLAR enclosure. In the New Tier Definition panel, specify the enclosure as EMC_CLAR.
For information on using the Storage Insight Add-on to define tiers, refer to the Veritas Operations Manager Storage Insight Add-on for Deep Array Discovery and Mapping 4.0 User's Guide.
To create the sample_dg disk group on the host sample_host2
For information on using the Add-on for Storage Foundation Administration to create disk groups, refer to the Veritas Operations Manager Add-on for Storage Foundation Administration 4.0 User's Guide.
This example discusses how you can create the sample_volstortemplate storage template to provision the storage from the HITACHI and the EMC_CLAR enclosures to the two mirrors that are part of the sample_vol1 volume. You can use this template to provision the storage from the HITACHI enclosure to Mirror 1 and the storage from the EMC_CLAR enclosure to Mirror 2.
Create the sample_volstortemplate storage template to provision the storage to the two mirrors of the sample_vol1 volume
This example provides the volume name as sample_vol1. For sample_vol1, under the Parameters tab, do the following:
For information on creating the storage template or editing the storage template, refer to the Veritas Storage Foundation Add-on for Storage Provisioning User's Guide.
