Information about
external storage system's target port:
- IP Address: Target
port IP address when port type is iSCSI port
- TCP Port Number:
Target TCP port number when port type is iSCSI port
- WWN / iSCSI Target Name: WWN to show the
target port when port type is Fibre Channel. If the port
type is iSCSI, iSCSI target name is displayed.

|
When the external path is connected to the
selected external volume, the LUN ID is displayed.

Status
|
Status of external
paths:
- Unknown: The status
of the mapping path is not known.
- Checking: The
system is checking the mapping path status.
- Blockade: The
mapping path is blocked.
- Normal: There are
no problems, the system is usable.
- Disconnect: The
external system or one of its mapped volumes has been
intentionally disconnected.
- External Device
Setting Changed: An external system setting has been
changed. For example, the path definition was deleted, or
the external system itself was replaced by another device.
- LDEV Size Reduced:
The external volume's capacity was reduced.
- Not Ready: The
reply from the external system was NOT READY.
- Illegal Request:
The reply from the external system was ILLEGAL REQUEST.
- Command Aborted:
The reply from the external system was ABORTED COMMAND.
- Busy: The external
system is busy.
- LDEV Reserved: The
external system is reserved.
- Response Error: The
external system is blocked because of an abnormal reply.
- Initiator Port: The
port attribute of the external system has been changed to
the initiator port.
- Unknown Port: The
port attribute of the external system is not known.
- Cannot Detect Port:
The path has been removed or the external system port cannot
be found.
- Timeout: Processing
was retried because an abnormal reply was returned; however,
processing has timed out.
- Passive: The
external system port is not active. Port status is normal
but the port is not used for I/O.
- Standby: The
external system port is standing by. The port status is
normal but cannot receive I/O.
- Target Error: Port
failures, such as controller blockade, are detected on the
external system.
- Unavailable: The
reply from the external system was
Unavailable. The external system
demands to change the connected port. Once the status
becomes Unavailable, the primary path
is changed to an alternate path in Standby status. When the
primary path is available, the status changes to Normal.
- Backoff: The reply
from the external system was Backoff.
A temporary error has occurred in the external volume and
the path is waiting for recovery. The primary path is not
changed to the alternate path immediately. After recovery,
the status changes to Normal.
- Destage Failed: The
writing of data from cache memory to the volume has failed.

Target Port
Asymmetric Access State
|
When the path mode is ALUA, the port state
of the external storage system:
- Active/Optimized:
The performance is in a good state.
- Active/Non-Optimized: Data can be sent and received, but
the performance is inferior to Active/Optimized.
A space is
displayed in one of the following cases:
- The path mode is
other than ALUA.
- Mapping of an
external volume is not completed.
