Follow power management procedures

Access to your volume data can be lost if you incorrectly power off all or part of a
system.
Use the management GUI or the CLI commands to power off a system. Using
either of these methods ensures that the data that is cached in the node canister
memory is correctly flushed to the RAID arrays.
Do not power off an enclosure unless instructed to do so. If you power off an
expansion enclosure, you cannot read or write to the drives in that enclosure or to
any other expansion enclosure that is attached to it from the SAS ports. Powering
off an expansion enclosure can prevent the control enclosure from flushing all the
data that it has cached to the RAID arrays.
Remove a node canister only when directed to do so by a service action. Physically
removing an active node canister means that it is unable to write any configuration
data or volume data that it has cached to its internal disk and the data is lost. If
both node canisters in a control enclosure are removed in quick succession, run
recovery actions, which might include restoring your volume data from a backup.

Set up event notifications

Configure your system to send notifications when a new event is reported.
Correct any issues reported by your system as soon as possible. To avoid
monitoring for new events by constantly monitoring the management GUI,
configure your system to send notifications when a new event is reported. Select
the type of event that you want to be notified about. For example, restrict
notifications to just events that require immediate action. Several event notification
mechanisms exist:
v Email. An event notification can be sent to one or more email addresses. This
v Simple Network Management Protocol (SNMP). An SNMP trap report can be
v Syslog. A syslog report can be sent to a data-center management system that
