2. Click Create. 3. Enter a name for the storage container. 4. Optionally, select the Enable storage contauiner capacity quota checkbox to specify a capacity quota for the storage container. 5. Click Create. Results For PowerStore X model appliances, a datastore is automatically created with the same name as the storage container. For PowerStore T model clusters, the user must create a datastore from the storage container in vCenter. Limit space usage by a storage container About this task To limit the amount of space a storage container consumes, set a quota on that storage container. The quota represents the total maximum size of the data that can be written to the vVols in the storage container. Space that snapshots and thin clones consume does not count towards the quota. Steps 1. Under Storage, select Storage Containers. 2. Select the storage container for which you want to set a quota and click Modify. 3. Select the Enable storage container capacity quota checkbox to enable a quota and specify the limit that you want, then click Apply. Results When the space that the storage container is using reaches or exceeds the high watermark for the quota, the system generates a notification. If the space used falls below the high watermark for the quota, the notification clears automatically. By default, the high watermark for the quota is 85%, but you can change this value. To remove the quota on a storage container, clear the Enable storage container capacity quota checkbox on the Properties panel for that storage container. Change a vCenter Server connection To change the vCenter Server that your PowerStore T model cluster is connected to, you must first remove the existing connection. Prerequisites Ensure that you have the IP address, username, and password for the vCenter Server. Steps 1. Under Compute, select vCenter Server Connection. 2. Click Disconnect. NOTE: You can no longer use your PowerStore T model cluster to manage VMs. 3. Use vCenter Server to unregister the VASA provider. NOTE: Unregistering the VASA provider causes vVol datastores to appear as disconnected, but any VMs that are already running are not impacted. New write operations such as powering up VMs are blocked when there is no active VASA connection. 4. Register the VASA provider for the new vCenter Server connection. 5. On the vCenter Server Connection screen of the PowerStore Manager, click Connect. 6. Type the IP address, username, and password for the new vCenter Server, then click Connect.

Limit space usage by a storage container
About this task
To limit the amount of space a storage container consumes, set a quota on that storage container. The quota represents the
total maximum size of the data that can be written to the vVols in the storage container. Space that snapshots and thin clones
consume does not count towards the quota.
Steps
1.
Under
Storage
, select
Storage Containers
.
2.
Select the storage container for which you want to set a quota and click
Modify
.
3.
Select the
Enable storage container capacity quota
checkbox to enable a quota and specify the limit that you want, then
click
Apply
.
Results
When the space that the storage container is using reaches or exceeds the high watermark for the quota, the system generates
a notification. If the space used falls below the high watermark for the quota, the notification clears automatically. By default,
the high watermark for the quota is 85%, but you can change this value.
To remove the quota on a storage container, clear the
Enable storage container capacity quota
checkbox on the
Properties
panel for that storage container.
Change a vCenter Server connection
To change the vCenter Server that your PowerStore T model cluster is connected to, you must first remove the existing
connection.
Prerequisites
Ensure that you have the IP address, username, and password for the vCenter Server.
Steps
1.
Under
Compute
, select
vCenter Server Connection
.
2.
Click
Disconnect
.
NOTE:
You can no longer use your PowerStore T model cluster to manage VMs.
3.
Use vCenter Server to unregister the VASA provider.
NOTE:
Unregistering the VASA provider causes vVol datastores to appear as disconnected, but any VMs that are
already running are not impacted. New write operations such as powering up VMs are blocked when there is no active
VASA connection.
4.
Register the VASA provider for the new vCenter Server connection.
5.
On the
vCenter Server Connection
screen of the PowerStore Manager, click
Connect
.
6.
Type the IP address, username, and password for the new vCenter Server, then click
