Changing options used by mirrors
Most pair operations are performed on multiple pairs. This is done using a journal or mirrors. You
can change the following options that affect the pairs in a mirror:
•
Path Watch Time—the interval from the time a path becomes blocked to the time when the
mirror is suspended.
•
Path Watch Time Transfer—forwards the master journal’s Path Watch Time value to the restore
journal.
•
Copy Pace—the pace at which data is copied
•
Transfer Speed—the speed for data transfer
•
Delta Resync Failure—the processing that takes place in the event of a failure.
Prerequisite information
Please be aware of the following when changing mirror options:
•
Mirror options can be changed on both primary and secondary systems.
•
To change mirror options, the status of the mirror must be one of the following:
Initial ◦
◦ Active
◦ Stopped
◦ Hold
◦ Holding
◦ Hold(Failure)
•
The Transfer Speed option can be changed if the mirror’s status is Active, Hold, or Holding.
When the status is Holding, the option can only be changed from the primary system.
•
When changing options for multiple mirrors, a changed value is applied to all the mirrors.
On the other hand, leave the options unchanged that you do not want to change.
Procedure 23 To change options for a mirror
1. In the Storage System tree, click Replication > Remote Replication.
2. Select the Mirrors tab, then select the mirror whose options you want to change.
3. From the Actions menu, click Remote Replication > Edit Mirror Options.
4. In the Edit Mirror Options window, for Path Watch Time, specify the interval from the time a
path becomes blocked to the time when the mirror is suspended. Ranges are from 1 to 59
minutes, 1 to 23 hours, or 1 to 30 days. A numeric value is required.
The interval must be the same for master and restore journals in the same mirror, otherwise
the journals suspend at different times. See next step to use this setting for both journals.
Important: If you want a mirror to split immediately after a path becomes blocked, ask HP
Technical Support to set system option mode 448 to ON and set system option mode 449 to
OFF.
