This chapter provides troubleshooting information.

General troubleshooting

General troubleshooting consists of the following kinds of errors and problems:
General errors with corrective actions
CU Path Status Problems
Split Pairs
Table 24 General troubleshooting
Error
The Remote Web Console computer hangs, or
Continuous Access Synchronous operations do
not function properly.
An initiator channel-enable LED indicator (on the
P9500 control panel) is off or flashing.
The pairs and/or secondary systems are not
displaying correctly.
A Continuous Access Synchronous error message
is displayed on the PC.
The secondary system path status is not normal.
Pair status is PSUE.
The paircreate or pairresync operation resulted
in a timeout error.
Corrective action
Make sure that the problem is not being caused by the PC or
Ethernet hardware or software, and restart the PC. Restarting the
Remote Web Console computer does not affect storage system
operations.
Make sure that all Continuous Access Synchronous requirements
and restrictions are met (for example, same LU type).
Make sure that the primary and secondary systems and data
paths are powered on and fully operational (NVS, cache).
Check all input values and parameters to make sure that you
entered the correct information on the Remote Web Console
computer (for example, remote system S/N and ID, path
parameters, P-VOL and S-VOL IDs).
Call HP Technical Support for assistance.
Make sure that the correct CU is selected.
Resolve the error, and then try the Continuous Access Synchronous
operation again.
Check the path status (RCU Status dialog box), and see
Table 25 (page 70).
See Table 26 (page 72).
Hardware failure: If the timeout error was caused by a hardware
failure, a SIM is generated. If this occurs, call service personnel,
then retry Continuous Access Synchronous operations after the
problem is fixed.
Heavy workload: If no SIM was generated, wait 5 or 6 minutes
then check the pair's status.
◦ If status changed correctly, the failed operation completed
after the timeout message was issued.
◦ If the pair status did not change as expected, heavy workload
might have prevented the operation from being completed.
Retry the operation when the system has a lighter workload.
A communication error may have occurred between the Remote
Web Console computer and SVP. See the HP StorageWorks
P9000 Remote Web Console User Guide for information and
instructions.
