Troubleshooting Logical Paths - HP StorageWorks P9000 User Manual

Table 15 General troubleshooting (continued)
Error
The pair create or pair resync operation resulted
in a timeout error.
Although Monitoring Switch is set to Enable, the
monitoring data is not updated.

Troubleshooting logical paths

Troubleshooting information for logical paths between storage systems is shown below.
Table 16 Logical path troubleshooting
Path status
Initialization Failed
Communication
Time Out
Port Rejected or
Pair-Port Rejected
Description
The link initialization
procedure for the
secondary system failed.
Communication between
the primary and secondary
systems timed out.
The primary and secondary
systems rejected the request
for establishing a logical
path because all resources
in both systems are in use
for other connections.
Corrective action
If the timeout error was caused by a hardware failure, a SIM is
generated. See "Service information messages (SIMs) " (page
If necessary, call HP Technical Support, and retry Cnt Ac-J operations
after the problem is solved.
If no SIM was generated, wait for a while (5 or 6 minutes), then
check the pair status of the pair(s) being created or resumed. If the
pair 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 Cnt Ac-J
operation from being completed. In this case, retry the Cnt Ac-J
operation when the system has a lighter workload.
If a communication error occurs between the Remote Web Console
computer and the SVP, see HP StorageWorks P9000 Remote Web
Console User Guide for instructions.
Because the time setting of SVP is changed, the monitoring data
might not be updated. Set Monitoring Switch to Disable, and set
Monitoring Switch to Enable again. For further information on
Monitoring Switch, see HP StorageWorks P9000 Performance for
Open and Mainframe Systems User Guide.
Corrective action
Make sure that the cables between the primary and secondary systems
are connected correctly.
Make sure that you entered the correct serial number (S/N) of the
secondary system and the correct path parameters (for example,
primary system port, secondary system port, and controller ID).
Make sure that the topology settings of the primary and secondary
systems ports are correct.
Make sure the secondary system is powered on, and that NVS and
cache are fully functional.
Make sure that network relay devices (cables, connectors, switches,
ESCDs, extender devices, communication lines, and all other devices
connected to the extenders) are properly configured and functional.
Delete the failed path. You may need to change the minimum paths
setting or delete the secondary system in order to delete the path.
After deletion finishes, add the path or secondary system. by using
the Add Path dialog box or the Add DKC dialog box.
Delete the failed path; also delete all paths and secondary systems
not currently in use. The primary system can be connected to up to
64 secondary systems with up to eight paths to each secondary
system.
Make sure that all ports on the primary and secondary systems are
properly configured: ordinary target ports or RCU target ports for
hosts, initiator and RCU target ports for primary and secondary
systems.
If necessary, connect to the secondary system to delete paths or
reconfigure ports, then reconnect to the primary system. After that,
add the path and secondary system.
