Resource Shortage
(Port)
or,
Resource Shortage
(Pair-Port)
The local and remote storage
system rejected the request
for creating a logical path
because all resources in the
local and remote storage
systems are being used for
other connections.
Delete the failed path, and also delete all paths and remote
storage systems not currently in use. The local storage system
can be connected to up to 64 remote storage systems with up
to eight paths to each remote storage system.
Make sure all local and remote storage system ports are properly
configured: ordinary target ports or RCU target ports for hosts, RCU
target ports for remote storage systems, initiator ports for local
storage systems.
If necessary, connect to the remote storage system to delete paths
or remote storage systems and reconfigure ports, then reconnect to
the local storage system. After that, add the path or the remote
storage system again by using the Add Path window or the Add
DKC window.
Serial Number
Mismatch
The serial number (S/N) of
the remote storage system
does not match the specified
serial number (S/N).
Make sure that you entered the correct remote storage
system S/N and path parameters (e.g., local storage system
port, remote storage system port, and controller ID). After
that, delete the failed path. You may need to change the
minimum paths setting or delete the remote storage system
in order to delete the path. After deletion finishes, add the
path and the remote storage system again by using the Add
Path window or the Add DKC window.
Make sure that you entered the correct controller ID, and also make
sure that the topology settings of the local and remote storage
system ports are correct.
Invalid Port
The specified port is not
configured as an RCP or
initiator port, or this path
already exists.
Make sure that the topology settings of the local and remote
storage system ports are correct.
Make sure that you entered the correct remote storage system S/N
and path parameters (e.g., local storage system port, remote
storage system port, and controller ID). After that, delete the failed
path. You may need to change the minimum paths setting or delete
the remote storage system in order to delete the path. After deletion
finishes, add the path and the remote storage system again by
using the Add Path window and the Add DKC window.
<blank> This path was not established.
Delete the failed path. You may need to change the minimum
paths setting or delete the remote storage system in order to
delete the path. After deletion finishes, add the path and the
remote storage system again by using the Add Path window
and the Add DKC window.
Pair-Port Number
Mismatch
The specified port in the
remote storage system is
physically disconnected from
the local storage system.
Make sure that you specified the correct remote storage
system port. Correct the port number if necessary.
Make sure that the local storage system port and the remote
storage system port are connected via cables to each other. If the
storage systems are not connected via cables, please connect them
via cables and then retry the operation.
Make sure that the topology settings of ports on the local and
remote storage systems are correct.
Pair-Port Type
Mismatch
The specified port in the
remote storage system is not
configured as an RCU Target
port.
Make sure that the specified port in the remote storage
system is configured as an RCU target port. Configure the port
as an RCU target port if it is not configured that way.
Communication
Failed.
The local storage system is
connected to the remote
storage system successfully,
but logical communication
timeout occurred.
Make sure that the remote storage system port and network
relay devices (e.g., cables and switches) are properly
configured and functioning.
