v Call Home. If your system is within warranty, or you have a hardware
maintenance agreement, configure your system to send email events to IBM if an
issue that requires hardware replacement is detected. This mechanism is called
Call Home. When the event is received, IBM automatically opens a problem
report, and if appropriate, contacts you to verify if replacement parts are
required. If you set up Call Home to IBM, ensure that the contact details that
you configure are correct and kept up to date as personnel change.
Set up inventory reporting
Inventory reporting is an extension to the Call Home email.
Rather than reporting a problem, an email is sent to IBM that describes your
system hardware and critical configuration information. Object names and other
information, such as IP addresses, are not sent. The inventory email is sent on a
regular basis. Based on the information that is received, IBM can inform you if the
hardware or software that you are using requires an update because of a known
issue.
Back up your data
Back up your system configuration data, volume data, and file systems.
The file modules back up their configuration after each configuration change.
Download the backup files regularly to your management workstation to protect
the data.
The storage system backs up your control enclosure configuration data to a file
every day. This data is replicated on each control node canister in the system.
Download this file regularly to your management workstation to protect the data.
This file must be used if there is a serious failure that requires you to restore your
system configuration. It is important to back up this file after modifying your
system configuration.
Your volume data or files in the file systems are susceptible to failures in your host
application or your Storwize V7000 Unified system. Follow a backup and archive
policy that is appropriate to the data that you have for storing the volume data on
a different system or the files on a different system.
Manage your spare and failed drives
Your RAID arrays that are created from drives consist of drives that are active
members and drives that are spares.
The spare drives are used automatically if a member drive fails. If you have
sufficient spare drives, you do not have to replace them immediately when they
fail. However, monitoring the number, size, and technology of your spare drives,
ensures that you have sufficient drives for your requirements. Ensure that there are
sufficient spare drives available so that your RAID arrays are always online.
Resolve alerts in a timely manner
Your system reports an alert when there is an issue or a potential issue that
requires user attention.
