Causes and solutions Problem
3. Reboot the host server or run a command that causes the system to recognize the device.
4. Start the monitoring application on the host and check whether the host has access to pair
volumes (see
“Fast Snap pair status” (page 15) ).
Cause: A port may go offline because access to a volume on another port has been rejected. The host computer attempts to
access the port and an error
occurs.
Solutions:
• Wait until the process has completed and then retry the task.
•
If a host application is installed to monitor the volume, stop the application.
Causes: RWC times out frequently.
•
RWC cannot respond to the SVP because the load is too heavy.
•
The time-out period is not an adequate length.
Solutions:
• Wait until the process has completed and then retry the task.
•
Verify the values for RWC’s RMI time-out period.
For more information about how to set RMI time-out period, see the HP XP7 Remote Web Console
User Guide.
