Managing S Series storage

Working with S Series storage components


An S Series storage component becomes visible on the Storage page once an S Series Node has been added to the HCP system. From this page you can monitor and manage existing components.

HCP uses S Series storage components to:

Monitor the general health, read permissions, and write permissions of the storage

Manage node settings

Add buckets and accounts

Suspend or abandon the S Series storage

Configure advanced settings

What you need to know


When you add an HCP S Series Node to your HCP system, HCP automatically creates a storage component, a storage pool (if an S Series storage pool doesn’t already exist), and a bucket. At the same time, the S Series Node creates a user account. The user account is granted permission to manage buckets and storage pools.

Bucket created on HCP system

The bucket HCP automatically creates when you add an S Series Node can be used only by that HCP system. The name of this bucket is:

hcpsrv-hcp-system-name

If a bucket with that name already exists (which can happen if the S Series Node is added to the HCP system a second time), HCP creates a new bucket named:

hcpsrv-hcp-system-name0

Subsequently, each time HCP automatically creates a new bucket on the S Series Node, HCP either increments the numeric suffix on the bucket name by one or reuses an earlier name from a deleted HCP-created bucket.

User account created on the HCP S Series Node

The user account HCP creates when you add an S Series Node is:

hcpsrv-hcp-system-name

If a user account with that username already exists (which can happen if the S Series Node is added to the HCP system a second time), HCP creates a new user account with the username:

hcpsrv-hcp-system-name0

Subsequently, each time HCP needs to create a new user account on the S Series Node, HCP either increments the numeric suffix on the username by one or reuses an earlier username from a deleted HCP-created account.

Deleting or abandoning an S Series storage component


If the storage represented by an S Series storage component is not being used to store objects in any namespaces defined on the HCP system, you can safely delete that storage component.

To delete an S Series storage component:

1.Retire the storage component. For more information on retiring a storage component, see Retiring storage.

2.On the Storage Retirement page, click on the retired S Series Node.

3.Click on Delete Volume. If the node is not successfully retired, theDelete Volume button is inaccessible.

Abandoning an S Series storage component removes the associated S Series Node from the HCP system. This can be done regardless of whether data is tiered to the S Series Node. If you abandon an S Series Node without retiring its data, that data becomes inaccessible even if you add the S Series Node to the system again. As a general rule, you should retire and delete a component instead of abandoning it.

To abandon an S Series storage component:

1.Go to the Storage Components page.

2.Click on an S Series Node.

3.On the Storage Node page that opens, click on the Manage tab.

4.Click on Abandon Component.

Working with S Series storage pools


HCP uses S Series storage pools to represent logical groups of storage components that can be used as storage tiers. Each storage pool consists of one or more storage components that are used to access the same type of storage.

When storing objects on S Series Nodes, HCP uses all the storage in all of the S Series Nodes that are contained in the storage pools. The total capacity of a given storage pool is the total amount of space remaining in all S Series Nodes connected to the HCP system.

You use the Storage section of the System Management Console to create, modify, manage, delete, and retire S Series storage pools and to monitor the health, availability, capacity, and usage of all the S Series Nodes associated with the storage pool.

When adding an S Series Node, you assign it to a storage pool. If no S Series storage pool exists, the Add Node wizard asks you to create a new storage component for the S Series Node. For more information on creating a storage component, see Creating an S Series storage component.
