Monitoring vaults that are at risk of access failure

In this scenario, you use IBM Spectrum® Control to check which vaults are at risk because of COS Accesser® node failures.

You have a backup application that uses IBM® Cloud Object Storage vaults. Because the application is critical to your business, you want to monitor the tolerance of the vaults to COS Accesser node failures and identify the vaults that are at risk of access failure.

For the vaults with a high risk of failure, you want to identify the access pools that the vaults depend on and the status of the COS Accesser nodes in the access pools.

  1. Click Storage > Object Storage Systems.
  2. Right-click the storage system that is used by your backup application and click View Details.
  3. In the navigation pane, click Overview.
    The Vaults by Accessers chart shows the tolerance of the vaults to COS Accesser node failures. For example, a line on the chart that shows a value of 1 Node Failure 57 Vaults at Risk indicates that 57 vaults rely on a single COS Accesser node for access. If the node fails, the vault cannot be accessed.
  4. To identify the vaults with an accessibility value of 1, click Vaults in the navigation pane. To sort the data, click the Accessibility column.

    In this scenario, there are some vaults that depend on only one access pool. The name of that access pool is shown in Access Pools. For other vaults that depend on multiple pools, a number is shown in Access Pools instead.
    Tip: To reduce the risk of access failure for the vaults that depend on only one access pool, add COS Accesser nodes to the access pool or deploy the vaults to other access pools.

    For the vaults that depend on multiple access pools, the warning status Warning status indicates that some of the COS Accesser nodes in the pools are not available.

  5. To investigate the cause of the access warning, click the number in the Access Pools column.
    You see that one of the access pools is shown with an error status Error status, which indicates that the COS Accesser nodes in the pool are not available.

  6. To identify the COS Accesser nodes that failed in the access pool, click Accesser Nodes in the navigation pane. To sort the data, click the Access Pool column.
Fix the COS Accesser nodes that failed or add COS Accesser nodes to the access pool.
