Investigating vaults that cannot be accessed

Edit online

In this scenario, you use IBM Spectrum Control to identify the vaults that cannot be accessed because of COS Accesser node failures.

About this task

You have a backup application that uses IBM Cloud Object Storage vaults. Because the application is critical to your business, you want to quickly identify vaults that cannot be accessed because of COS Accesser node failures. You also want to know the access pools that the vaults depend on and the COS Accesser nodes that failed in those pools.

Procedure

  1. To determine whether any of your vaults cannot be accessed, 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 first line of the Vaults by Accessers chart shows the number of vaults that cannot be accessed, for example, Inaccessible 4.
  4. To identify the vaults that are inaccessible, click Vaults in the navigation pane. To sort the data, click the Accessibility column.

    A value of 0 in the Accessibility column indicates that the vault is inaccessible. The error status Error status indicates that the vault is inaccessible because none of the COS Accesser nodes that are configured for the vault are available. In this scenario, all the inaccessible vaults are configured to use just one access pool. The name of that access pool is shown in Access Pools.

  5. To identify the COS Accesser nodes that failed in the access pool, click the access pool name. Then, click the Accesser Nodes tab.

What to do next

To restore access to the vaults, fix the COS Accesser nodes that failed or add COS Accesser nodes to the access pool.
