HP Insight Recovery 1.0 Online Help (Document Format)

Enter the local and remote Array WWN (World Wide Name) as
provide by the storage administrator. There should be no dashes,
spaces, or colons in the WWN – only consecutive hexadecimal
characters.
Local and Remote Array WWN
Enter the Failsafe setting for the Storage Replication (DR) Group
in the EVA array. Possible values are:
Failsafe enabled— All host I/O to the
DR group
is stopped if
data cannot be replicated between the source array and
destination array. This ensures that both arrays will always
contain the same data.
Failsafe disabled—If replication of data between the source
and destination array is interrupted, the host continues writes
to the source array, but all remote replication to the destination
array stops and I/Os are put into the DR group write history
log until remote replication is re-established.
The default is Disabled.
Failsafe Mode
Specifies whether the
DR group
can fail over to the destination
(Recovery) site in cases where the data at the destination site may
not be current. When this is set to True, Insight Recovery proceeds
with the failover even in cases where the destination data may
not be current. When this is set to False, Insight Recovery does
not allow the failover to occur if the destination data is not current.
The default is True.

for all Command View EVA servers at both the Primary and Recovery Sites.

Notes
This operation may take several minutes to complete, because storage information is being validated.
DR group is the Continuous Access EVA term for Storage Replication Group.
For a Storage Replication Group to be successfully added to an HP Insight Recovery configuration, the
entered or selected Command View EVA servers must be actively managing the EVA arrays.
The default value for UseNonCurrentDataOk is True, and with this setting, during a site failover all
Recovery Groups can be successfully failed over by Insight Recovery even if the recovery site does not
have current data for some or all Recovery Groups. It is possible that the arrays at both sites may not
be in sync (i.e. the data at the recovery site may not be current) at the time when you click Change
local site to Primary at the Recovery Site. If the data at the Recovery Site is not current at the time of a
site failover for a given Recovery Group, if the UseNonCurrentDataOk parameter is set to False (the
non-default value) for the corresponding Storage Replication Group, the Recovery Group may not
failover successfully.
In such a case, the Storage Replication Group associated with this Recovery Group can be manually
failed over using the Command View EVA server at the Recovery Site and then the Recovery Group
can be failed over to the Recovery Site using Insight Recovery. In such a case, the most current data
that was not replicated from the non-functional Primary Site array would be irrecoverably lost.
When editing Storage Groups:
You can only change the Command View EVA servers and their credentials, as well as the Failsafe
Mode and UseNonCurrentDataOk settings. No other fields can be edited. If you must edit the other
fields, delete the current storage replication group and create a new one.
