This
operation lists all of the devices that are part of a specific storage
control session. A storage control session is comprised of all of
the devices, on a particular storage control, that contain volumes
that belong to a unique XRC session. The first device listed is the
one that was used to initially set up the session.
The command syntax is as follows:
F ANTAS000,LISTDVCS dddd ss
The
following definitions apply to the example above:
- dddd
- The address of a device that is attached to the primary storage
control you want to display. The storage control must have XRC-capable
Licensed Internal Code (LIC) that supports this function.
- ss
- The storage control session number (which you can obtain by issuing
a F ANTAS000,LISTSESS xxxx command—see LISTSESS Operation for more information).
Example: Issue the following command to list the devices
owned by storage control session 04 of the storage control for device
F40:
F ANTAS000,LISTDVCS 0F40 04
Result: The following is a possible response to this command:
ANTX8927I 0F40 – XA04 – 25(0F40) 0F(....)
This means that session 04 is an active storage control session
that has two devices. Device 0F40 relates to device channel connection
address 25. The device that relates to device channel connection address
0F is offline.
The operation output contains: the system data mover message number,
ANTX8927I; the address of the device (which is 0F40); information
about the session (see
LISTSESS Operation for
more information about the session status syntax); and multiple fields
that provide information about each session for the specified device.
The information for each session has a format of
cc(dddd)s,
where the following apply:
- cc
- The channel connection address (CCA).
- dddd
- The device number. If the device is offline, the value is "....".
- s
- An "s" indicates that the session is suspended. A blank indicates
that the session is not suspended. This field is reported for ESS
storage subsystems, only.
Results: The following are possible responses to the command:
- ANTX8927I 0F40 – XA04 – 25(0F40) 0F(....)—This
means that session 04 is an active storage control session that has
two devices. Device 0F40 relates to device channel connection address
25. The device that relates to device channel connection address 0F
is offline.
- ANTX8928I 0F40 NO DEVICES FOR STORAGE CONTROL SESSION
04—This means that storage control session 04 is not in the
storage control.
