The following table provides operation and display troubleshooting information for BC pairs.
Corrective actionError
RWC hangs, or BC operations do not
function properly.
• Make sure all BC requirements and restrictions are met.
• Make sure the storage system is powered on and fully functional.
• Check all input values and parameters to make sure that you entered
the correct information in the BC windows (such as P-VOL and S-VOL
IDs).
Make sure the correct volumes are selected.The volume pairs are not showing
correctly.
Click Tasks in the Storage Systems tree and select the failed task to check
the message.
A BC error message is displayed in RWC
during an operation.
If you are using the previous RWC GUI, which is shown in a secondary
window, complete the following:
1. Select the failed volume in the Preview list in the Pair Operation window.
2. Right-click to show the menu.
3. Click Error Detail.
For the list of error codes and corrective actions, see HP XP P9000 Remote
Web Console Messages.

host using RAID Manager. If not, P9500 detected an error condition during
Pair status is incorrect (or unexpected).
BC operations. Check the RWC error log. If necessary, call the HP Technical
Support for assistance.
Troubleshooting pinned tracks
If a pinned track occurs on a BC P-VOL or S-VOL, the storage system suspends the pair. Contact
your HP representative for assistance in recovering pinned tracks.
Troubleshooting extended copy times
The following table describes the causes for bottlenecks that result in long copy time.
ResponseCause
Reexamine the configuration. For information about
checking the MP usage rate, see the HP XP P9000
Performance for Open and Mainframe Systems User Guide.
A processor whose MP usage rate exceeds 80% exists
within the processor blade to which the P-VOL and S-VOL
are allocated.
Disable the option. For more information about disabling,
see “System options that affect performance” (page 38).
The Host I/O Performance option is enabled.
Make sure the configuration of the S-VOL’s HDD or external
storage is the same as the P-VOL’s.
The S-VOL’s HDD or external storage performance is lower
than the P-VOL’s.
