Product name of the connected external array
WWN: WWN identifying the port in the external array for which the connection setting
is completed. ◦
◦ Path: Number of set paths.
◦ I/O TOV: Value specified as the timeout for I/O to the external LU.
◦ Qdepth: Number of Read/Write commands that can be issued (queued) to the external
LU at one time.
◦ Path Watch: Time period beginning when the connection of all paths to the external LU
are down and ending when the external LU is blocked.
◦ Mode: How alternate paths between the local array and external array work. Alternate
path modes include:
– Single: Uses only the path with the highest priority (primary path) to execute I/O to
the external LU. When an error occurs in the primary path, the path with the second
highest priority is used.
– Multi: Uses all set paths at the same time to execute I/Os to the external LU,
distributing the work load.
◦ Status: Status of the path set in the port identified by the WWN. The highest emergency
level status appears when two or more paths are set. Statuses include:
– Normal: Path is normal.
– Unknown: Path status is unknown.
– Blockade: Path is blocked.
– Disconnect: Connection to the external array or external LU was intentionally stopped
using the Disconnect Subsystem or Disconnect Volume command.
