Table 54 Troubleshooting problems with status of logical paths
Corrective action Description Pair status
Ensure that the local and remote arrays
are connected correctly via cables.
Ensure that you entered the correct
serial number (S/N) of the remote array
and the correct path parameters (for
example, local array port, remote array
port, and controller ID).
Ensure that the topology settings of the
local and remote array ports are
correct.
Link initialization procedure for the
remote array failed. Initialization Failed
Ensure that the remote array is powered
on, and NVS and cache are fully
functional.
Ensure that the 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 might need
to change the minimum paths setting or
delete the remote array to delete the
path. After deletion finishes, add the
path or remote array.
Communication between the local and
remote arrays timed out. Communication Time Out
Delete the failed path and all paths and
remote arrays not currently in use. The
local array can be connected to up to
64 remote arrays with up to eight paths
to each remote array.
Ensure that all ports on the local and
remote arrays are properly configured:
ordinary target ports or RCU target
ports for hosts, RCU target ports for
remote arrays, initiator ports for local
arrays.
If necessary, connect to the remote
array to delete paths or remote arrays
and reconfigure ports, and reconnect
to the local array. After that, add the
path and remote array again.
Array rejected the request for
establishing a logical path because
all resources in the local and remote
arrays are being used for other
connections. Resource Shortage (Port)
or
Resource Shortage (Pair-Port)
Ensure that you entered the correct
remote array S/N and path parameters
(for example, local array port, remote
array port, and controller ID). After that,
delete the failed path. You might need
to change the minimum paths setting or
delete the remote array to delete the
path. After deletion finishes, add the
path and the remote array.
Ensure that you entered the correct
controller ID. Ensure that the topology
settings of the local and remote array
ports are correct.
Remote array's serial number (S/N)
does not match the specified serial
number (S/N). Serial Number Mismatch
