General troubleshooting

General troubleshooting consists of the following kinds of errors and problems:
General errors with corrective actions
CU Path Status Problems
Suspended Pairs
For troubleshooting information on PPRC and P/DAS operations, see the IBM PPRC and P/DAS
user documentation: Planning for IBM Remote Copy (SG24–2595), Advanced Copy Services
(SC35–0355), and DFSMS MVS V1 Remote Copy Guide and Reference (SC35–0169).
Table 31 General troubleshooting
Error
The Remote Web Console computer hangs, or
Continuous Access Synchronous Z operations do
not function properly.
An initiator channel-enable LED indicator (on the
P9500 control panel) is off or flashing.
The pairs and/or remote systems are not
displaying correctly.
A Continuous Access Synchronous Z error
message is displayed on the PC.
There is a problem with the Remote Web Console
or Continuous Access Synchronous Z software.
The remote system path status is not normal.
Pair status is Suspended (pair suspended-error).
Monitoring data is not updated though the
Monitoring Switch option is set to Enable.
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 Z requirements
and restrictions are met (for example, Track format, LVI, VOLSER,
DFW).
Make sure that the main and remote system 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, M-VOL and R-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
Z operation again.
Make sure that the problem is not the PC or LAN hardware or
software. Try restarting the PC and reconnecting to the storage
system.
Check the path status (RCU Status dialog box), and see
Table 32 (page 80).
See Table 33 (page 81).
Because the time setting of SVP is changed, the monitoring data
might not be updated. Disable Monitoring Switch, then enable again.
For more information on Monitoring Switch, see the HP StorageWorks
P9000 Performance for Open and Mainframe Systems User Guide.
