Follow proper Storwize V7000 Gen2 power management
procedures
You can lose access to volume data if you incorrectly power off all or part of a
Storwize V7000 Gen2 system.
Always use the management GUI function to power off the system.
Only power off or remove a node canister if instructed to do so in a service action.
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 cached to the RAID arrays.

Follow proper 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 system fails properly in the case of
powering down individual file modules and that data that is cached in the node
canister memory is correctly flushed to the RAID arrays for the disk system.
The Storwize V7000 Unified system uses a pair of file modules for redundancy.
Follow the appropriate power down procedures to minimize impacts to the system
operations. See "Turning off the system" in the Storwize V7000 Unified
information center.
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.

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
mechanism notifies individuals of problems. Individuals can receive notifications
wherever they have email access which includes mobile devices.
sent to a data-center management system, such as IBM Systems Director, that
consolidates SNMP reports from multiple systems. Using this mechanism, you
can monitor your data center from a single workstation.
