Table 30 Troubleshooting RCU path status problems
Path Status Description Corrective Action
Initialization Failed The link initialization procedure to
the RCU failed.
Verify that you entered the correct RCU S/N and SSID
and path parameters (Fibre: MCU port, RCU port, CU
number and Controller ID. Serial: port, link address
and logical address).
For serial, verify that the correct MCU port is
configured as an RCP and that the correct RCU port is
configured as an LCP.
For Fibre Channel interface, verify that the Fibre
Channel topology settings of the MCU and RCU ports
are correct.
Communication Time
Out
Communication between the
MCU and RCU timed out.
Verify that the RCU is powered on and fully functional
(NVS and cache ON).
Verify that the remote copy connection hardware is
properly configured and functional, including cables,
connectors, ESCDs, repeaters, extender devices,
communication lines, and all other devices connected
to the extenders.
Delete the failed path. You may need to change the
minimum paths setting or delete the RCU to delete the
path. Then add the path/RCU using Add Path or Add
RCU.
Resource Shortage
(MCU/RCU)
The MCU/RCU rejected the
establish logical path link control
function because all logical path
resources in the MCU/RCU are
being used for other connections.
Delete the failed path, and also delete all paths and
RCUs not currently in use. The MCU can be
connected to up to four RCUs with up to eight paths
(four for serial 3990) to each RCU.
Verify all MCU and RCU ports are properly
configured:
• Serial – LCPs for hosts and MCUs, RCPs for RCUs.
• Fibre – ordinary target ports or RCU target ports
for hosts, RCU target ports for MCUs, initiator
ports for RCUs.
If necessary, connect to the RCU to delete
paths/RCUs and reconfigure ports, then reconnect to
the MCU.
Add the path/RCU again using Add Path or Add
RCU.
Serial Number
Mismatch
The RCU’s S/N does not match
the specified S/N.
Verify that you entered the correct RCU S/N and SSID
and path parameters (Fibre: MCU port, RCU port, CU
number and Controller ID. Serial: port, link address
and logical address).
Delete the failed path. You may need to change the
minimum paths setting or delete the RCU to delete the
path. Then add the path/RCU using Add Path or Add
RCU.
For Fibre Channel interface, verify that you entered
the correct Controller ID and that the Fibre Channel
topology settings of the MCU and RCU ports are
correct.
