Explanation
The number of port to port fabric connections, or logins, between the SAN Volume Controller node and a storage controller has decreased. This might be caused by a problem on the SAN or by a deliberate reconfiguration of the SAN.
Action
- Check the error in the cluster error log to identify the object ID associated
with the error.
- Check the availability of the failing device using the following command
line: svcinfo lscontroller object_ID. If the command fails with
the message "CMMVC6014E The command failed because the requested object is
either unavailable or does not exist," ask the customer if this device was
removed from the system.
- If "yes", mark the error as fixed in the cluster error log and continue
with the repair verification MAP.
- If "no" or if the command lists details of the failing controller, continue
with the next step.
- Check whether the device has regained connectivity. If it has not, check
the cable connection to the remote-device port.
- If all attempts to log in to a remote-device port have failed and you cannot solve
the problem by changing cables, check the condition of the remote-device port
and the condition of the remote device.
- Start a cluster discovery operation by rescanning
the fibre-channel network.
- Check the status of the disk controller. If all disk controllers show a "good" status, mark
the error that you have just repaired as "fixed". If any disk controllers do not
show "good" status, go to start MAP. If you return to this step, contact the
support center to resolve the problem with the disk controller.
- Go to repair verification MAP.
