Action

Cause

Change to the Modify mode and retry the operation.

Remote Web Console is not in the Modify mode.

Connect the external port of the local storage system and
the port of the external storage system.

Port of the local storage system and port of the external
storage system are not connected.

Connect the cable to the correct port of the switch. Or
change the port status of the switch into the normal status.

Cable for the switch is not connected appropriately. Or
the port of the switch is blocked.

Make sure the zone configuration is correct so that the
external port of the local storage system can communicate
with the port of the external storage system.

Zoning for the switch is not set appropriately.

Connect the external storage system to the External port of
the local storage system. Or change the connected port to
External.

External storage system is not connected to the port set to
External of the local storage system.

Perform one of the following:

Use the external port in the Standard mode.

Change the Internal/External MIX mode of the external
port to the Standard mode.

External volume cannot be used because the used external
port is in the Internal/External MIX mode. This problem
occurs when the external volume is not a command device.

Release the reserved state of the external volume.

External volume returned RESERVATION CONFLICT.

Cancel the port security setting or change the security of
the external storage system so that the local storage system
can access the port of the external storage system.

Port security is set on the external storage system.

Configure an LU on the port of the external storage system.

No LU is configured on the port of the external storage
system.

Perform one of the following:

Increase the capacity of the external volume so that the
capacity of the external volume is equal to or larger
than the capacity supported by XP External Storage.

Use a security function or delete the LU setting from the
port of the connected external storage system so that
the local storage system cannot recognize the volume
with insufficient capacity.

Capacity of the external volume is less than the supported
capacity of XP External Storage.
