DS8000

Add DS8000 storage systems to get performance and asset, capacity, and configuration metadata analyzed so that you can detect performance issues, changes in storage usage, and plan for future storage needs.

Use the following information to add storage systems so that they can be monitored and that metadata can be collected, analyzed, and presented in the GUI.
Host names or IP addresses
The hostnames or IP addresses of the Hardware Management Console (HMC). Use hostnames if your IP addresses change regularly. For high availability, connect to both HMCs for each DS8000. Depending on what is supported in your environment, you can enter an Internet Protocol version 4 (IPv4) or IPv6 address. If you enter an IPv6 address, the preferred representation is written as eight groups of four hexadecimal digits. Example: 2001:DB95:0000:1234:0000:0000:5678:ABCD.
User name and Password
The user name, which is the same as the user name for the enterprise storage server network interface (ESSNI), and password for logging in to the storage system. The user must have Monitor privileges for the storage system so that the metadata that is analyzed and presented in the GUI can be collected.
User Name and PassTicket key

The user name and RACF PassTicket for logging in to the storage system. This user name is the same as the user name for the enterprise storage server network interface (ESSNI). The user must have Monitor privileges for the storage system so that the metadata that is analyzed and presented in the GUI can be collected.

For more information about RACF authentication, see The RACF PassTicket.

Tip: Why not create a dedicated user account to manage the monitoring of your storage systems more efficiently? So, instead of using an existing user account, create a new user account to connect to and collect metadata from your storage resources.
Important:
  • Status, configuration, and capacity metadata are collected by probes and aggregated once every 24 hours.
  • For more detailed monitoring, the value for used capacity is collected once every hour at the storage system and pool levels. With this turbo boost to metadata collection, you can better monitor how fast pools are changing and take more timely action to optimize their capacity. It can also help you understand daily trends and avoid storage shortages before they occur.

    To change the one-hour interval for collecting the value for used capacity, contact IBM® Support.

  • Capacity and configuration (probe) metadata can't be collected for DS8000 storage systems in the following situations:
    • The storage systems is in maintenance mode. To ensure that metadata can be collected, schedule and run probes during non-maintenance times. For information about how to schedule and run probes, see Modifying the schedules for collecting metadata.
    • The processor enclosure (also known as the central electronic complex or CEC) for the DS8000 storage system is down or unavailable. If the problem persists in subsequent metadata collections by probes, open a support case for the storage system at https://www.ibm.com/support.
