HP Insight Recovery Technical White Paper

After the Import process has been completed, e
ach
r
ecovery
logical server
is in “Maintenance Mode”,
meaning that it
should
be
tested
at the
recovery site
to ensure
that it is working properly.
Once
this is
done, each of the
r
ecovery
logical server
s
must
be taken out of “Maintenance Mode”
in order to
enable them for automatic activation
by Insight Recovery
in the event of a site failover.

ailover
A
site
failover
in
volves failing over
the
set of workloads running at the
primary site
that are
protected
by
Insight Recovery
to
the
recovery site
.
A
planned failover
is performed while the
primary site
is still
capable of supporting the workloads under protection of
Insigh
t Recovery
. A planned failover may
be performed in anticipation of an imminent disaster, s
uch as an approaching hurricane
or a planned
utility outage (power shutdown for maintenance, etc)
.
An
un
planned failover
is one in which the
failover to the
recover
y site
is performed without advance warning or planning, typically after the
primary site
is no longer capable of supporting the workloads under protection of
Insight Recovery
.
An unplanned failover may be required in order to recover from the effects of
an unexpected event,
such as a fire
or flood, etc.
The admin performs the
foll
owing steps to
perform a planned
site
failover using Insight Recovery:

At the
primary site
, p
erform an orderly shutdown of all
logical server
s at the
primary site
that are
to
be failed over
.
Then
,
click the
Change Local Site to
Recovery
button
. This will deactivate all
the
logical server
s that are being managed by Insight Recovery.

Verify that the storage being replicated to the
recovery site
containing images associated w
ith the
DR
-
protected
logical server
s is
synchronized
with respect to the state of the storage at the
primary
site
.

At the recovery site, c
lick the
Change Local Site to
Primary
button
(illustrated in Figure 11
)
.
Once
the
Failover Site
command is initiate
d using Insight Recovery at the
recovery site
, it proceeds to
completion automatically.

Monitor the progress of the
F
ailover
Site
command using the Jobs screen in the
Insight Recovery
user interface at the
recovery site
.
This is a high level description
of the planned site failover procedure.
There are difference
s in the
detailed steps
to be performed
(including the order of steps) in the case of an
unplanned
failover
.
