Table 27 Troubleshooting RCU Pat h Status Problems
Path Status
Description Corrective Ac tion
Initialization
Failed
The link initialization procedure to the
RCU failed.
Make sure that t
he
MCU and RCU are
physically an
d
correctly connected.
Make sure that
you entered the correct
RCU S/N and SSI
D
and path parameters
(port, link ad
dress, logical address).
Make sure the c
orrect MCU port is
configured as
an initiator port and the
correct RCU port is configured as an RCU
target port.
Communication
Time Out
Communications bet ween the MCU and
RCU timed out.
Make sure the RCU is powered on and
fully functional (NVS, cache).
Make sure that the remote copy connection
hardware (cables, connectors, switches,
extender devices, communication lin es,
and
all other devices connected to the
extenders) are properly configured a nd
functional.
Delete the failed path. You may need
to
change the minimum paths setting or
delete the RCU in order to delete the path.
Then add the path/RCU using Edit 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.
TheMCU canbeconnected to up to four
RCUs with up to eight paths to each RCU.
Make sure that all MCU and RCU ports
are properly configured: 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 pa th/RCU again using Edit Path
or
Add RCU.
Serial Number
Mismatch
The RCU’s S/N does not match the
specified S/N.
Mak
e
sure that you entered the correct
RCU
S/N
and SSID and path parameters
(po
rt, link address, logical address).
Delete the failed path. You may need
to
change the minimum paths setting or
delete the RCU in order to delete the path.
Then add the path/RCU using Edit Path
or
Add RCU.
Fibre: make sure that you entered the
correct Controller I D, and also make sure
that the Fibre Channel topology settings of
the MCU and RCU ports are correct.
