Complete this task to view general properties of the Global Mirror session or information about Global Mirror session
failures.
Perform the following steps to view Global Mirror session
properties:
- In the navigation, select . A page containing a list of sessions displays. Select one or more sessions
on which to perform an action.
- In Global Mirror —
Main Page, select Properties from the Select Action drop-down
list. Then click Go.
- The Global Mirror session
properties page is displayed. On this page, you can view general properties
of the Global Mirror session
by selecting the General tab, or information about
failures on the Global Mirror session
by selecting the Failures tab. When you
select theGeneral tab, the following session properties
display:
- Global Mirror properties
- Session number
- The session ID that you assigned, '01-FF' (1-255 decimal).
- Master storage unit
- The serial number (or nickname) of the master storage unit.
- Master LSS
- The LSS ID which consists of a Storage Unit ID followed by two hexadecimal characters (00 - 1F) that
identify a Global Mirror master LSS ID.
- Subordinate ID
- The serial number (or nickname) and LSS of the subordinate storage unit,
if applicable. If there subordinates are not available, the column will display
"No subordinates."
- Consistency Group Interval
- The amount of time that Global Mirror is
in Global Copy mode between the formation of each consistency group. The default
is zero seconds, which means that Global Mirror will
continuously form consistency groups as fast as the environment will allow.
- Maximum Coordination Interval
- The maximum time that Global Mirror will
allow for the formation of the consistency group before failing this consistency
group, up to 65,535 milliseconds. Having this time value set ensures that
if there is an error recovery event or communications problem, applications
will not experience significant impact from consistency group formation failures.
- Time writes Inhibited at Remote Site
- The maximum time that will be spent sending the current consistency group
to the remote site before completion of the current consistency group fails.
The default is 30 seconds.
- Consistency Group Attempts
- The number of attempts recorded since the last successful consistency
group was formed in a Global Mirror session.
When you select the
Failures tab,
the following properties display:
- Select failure
- Most recent failure
- Specifies that information about the most recent failure of the consistency
group formation attempt is displayed.
- Previous failure
- Specifies that information about the next to last failure of the consistency
group formation attempt is displayed.
- First failure
- Specifies that information about the first failure of the consistency
group formation is displayed.
- Failure data
- Storage unit sequence
number
- The five-digit storage unit sequence
number.
- Failing LSS
- The LSS number that has caused the failure of the consistency group formation.
- Failure reason
- The error reason of the failure of the consistency group formation attempt.
- Master state
- The state of the master storage unit for the Global Mirror failure.
