Procedure 23 To change options for a mirror
1. In the Remote Web Console main window, select Actions > Remote Copy > Continuous Access
Journal Z > Journal Operation. The Journal Operation window displays.
2. Click to change the mode from View to Modify.
3. In the table pane, right-click the desired journal and then select Mirror > Change Mirror Option.
4. For Unit of Path Watch Time, specify the unit of time for Path Watch Time, minute, hour, or
day.
5. For Path Watch Time, specify the interval from the time a path becomes blocked to when the
mirror is split (suspended). The interval must be the same for master and restore journals in
the same mirror (see next item).
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.
6. For Forward Path Watch Time, specify whether to forward the Path Watch Time value of the
master journal to the restore journal. If the Path Watch Time value is forwarded from the master
journal to the restore journal, the two journals will have the same Path Watch Time value.
- Yes: The Path Watch Time value will be forwarded to the restore journal.
- No: The Path Watch Time value will not be forwarded to the restore journal. No is the default.
- Blank: The current setting of Forward Path Watch Time will remain unchanged.
CAUTION: This option cannot be specified in the secondary site. For a pair using the delta
resync configuration, select Yes in the primary site
7. For Copy Pace, specify the pace for initial copy activity per volume. This field cannot be
specified on the remote system. Low is the default. When specifying Medium, ensure that write
I/O is 10 MB/s or less per parity group. If it exceeds 10 MB/s, pairs may be suspended.
When specifying High, ensure that I/O will not occur. If update I/O occurs, pairs may be
suspended.
8. For Transfer Speed, specify the line speed (in Mbps (megabits per second)) of data transfer.
Specify one of the following: 256, 100, or 10. Recommended values are:
Use 10 when the transfer speed is 10 to 99 Mbps.
Use 100 when the transfer speed is 100 to 255 Mbps.
Use 256 when the transfer speed is 256 Mbps or higher.
