NOTE:
Dell EMC recommends using virtual storage.
NOTE:
After you create a disk group using one storage type, the system will use that storage type for additional disk
groups. To switch to the other storage type, you must first remove all disk groups.
Creating disk groups and pools
The panel that is displayed when creating disk groups and pools is dependent upon whether you are operating in a virtual storage
environment or a linear storage environment.
Virtual storage environments
If you are operating in a virtual storage environment, the system scans all available disks, recommends one optimal storage configuration,
and displays the suggested disk group layout within the panel.
In a virtual storage environment, the storage system automatically groups disk groups by pool and tier. The disk groups also include a
description of the total size and number of disks to be provisioned, including the configuration of spares and unused disks.
If the system is unable to determine a valid storage configuration, the wizard lists the reasons why and provides directions on how to
achieve a proper configuration. If the system is unhealthy, an error is displayed along with a description of how to fix it. Follow the
recommendations in the wizard to correct the errors, then click
Rescan
to view the optimized configuration.
For a system with no pools provisioned, if you are satisfied with the recommended configuration, click
Create Pools
to provision the
system as displayed in the panel and move on to attaching hosts. For a system that contains a pool, if you are satisfied with the
recommended configuration, click
Expand Pools
to provision the system as displayed in the panel.
If your environment requires a unique setup, click
Go To Advanced Configuration
to access the Create Advanced Pools panel. Select
Add Disk Group and follow the instructions to manually create disk groups one disk at a time. Select Manage Spares and follow the
instructions to manually select global spares.
Linear storage environments
If you are operating in a linear storage environment, the Create Advanced Pools panel opens.
Select
Add Disk Groups
and follow the instructions to manually create disk groups one at a time. Select
Manage Spares
and follow the
instructions to manually select global spares. Click the icon for more information about options presented.
