Changing devices
To change device data, you have to follow the same panel flow as
for defining a device:
- Changing device and control unit definitions
- Changing CSS-related definitions
- Changing OS-related definitions
The following steps describe the panel flow and where you can change
which data.
- On the I/O Device List, select a device or a group of
devices and the Change action from the
context menu (or action code c ). HCD shows the following
panel:
*-------------------------- Change Device Definition -------------------------*
| CBDPDV30 |
| |
| Specify or revise the following values. |
| |
| Device number . . . . . . . : 0005 (0000 - FFFF) |
| Number of devices . . . . . : 4 |
| Device type . . . . . . . . : 3390 |
| |
| Serial number . . . . . . . . __________ + |
| Description . . . . . . . . . ________________________________ |
| |
| Volume serial number . . . . . ______ + (for DASD) |
| |
| PPRC usage . . . . . . . . . . _ + (for DASD) |
| |
| Connected to CUs . 0001 ____ ____ ____ ____ ____ ____ ____ + |
| |
| ENTER to continue. |
*-----------------------------------------------------------------------------*
Depending
on whether you invoke this action for a single device or a group of
devices, the line Number of devices shows
how many devices are affected by the change.
- On the Change Device Definition panel
you can change device and control unit definitions such as:
- Serial number
- Description
- Volume serial number
- PPRC usage
- Control unit connections
- After pressing the Enter key, the Device
/ Processor Definition panel is displayed. Select a processor
and press the Enter key to change the following CSS-related definitions:
- Subchannel set ID
- Unit address
- Time-Out
- STADET
- Preferred CHPID
- Explicit device candidate list
- After pressing the Enter key twice , the Define Device to Operating
System Configuration panel is displayed. Select an operating system
and the Select (connect/change) action
from the context menu (or action code s ) if you want
to change the following OS-related definitions:
- Parameters/Features
- Assignments to esoterics
- After pressing the Enter key again, the Assign/Unassign Device
to Esoteric panel is displayed. If you want to change the assignment
of devices to esoterics, type over the values in the Assigned column
by either Yes or No.
- Press the Enter key twice to return to the I/O Device List.
Changing CSS-related definitions of a group of devices
You can change CSS-related definitions of a group of devices using
the CSS group change action. This helps
you, for example, to attach a group of DASDs to another control unit.
To do this, the devices to be changed must be in the same device
group, that is, they must all be of type, for example, DASD or TAPE.
- On the I/O Device List select one
or more devices and use the CSS group change action
from the context menu (or action code g ). The Change
Device Group panel is displayed.
*--------------------------- Change Device Group -----------------------*
| |
| |
| Specify the control units the devices are attached to. |
| |
| Connected to CUs . . 00D1 00D2 ____ ____ ____ ____ ____ ____ +|
*-----------------------------------------------------------------------*
HCD displays
the definition of the first device in the group. You can modify this
definition and HCD applies the definition to all devices in the group.
- After pressing the Enter key, HCD displays the Change Device Group
/ Processor Definition panel, where you can select the processors
for which you want to change the CSS-related definitions. For an example
of this panel, see page *** that shows the Device
/ Processor Definition panel which is similar to the one you see here.
Changing esoterics for a group of devices
For a description of how to change esoterics for multiple devices,
refer to Adding devices to esoterics.
Changing OS-related definitions of a group of devices
You can change OS-related definitions for a group of devices using
the OS group change action (or action
code o ). This helps you, for example, to attach a
group of devices to another operating system. The device parameter/features
will be the same for all devices in the group.
If you want to change OS-related definitions for PAV
devices, HCD displays a similar dialog as shown in Figure 63 which
lets you change or specify the subchannel set ID where to place the
device or the device group.
- On the I/O Device List for device groups or
single devices select one or more devices or groups and
use the OS group change action from the
context menu (or action code o ). HCD displays
the Change Device Group / Operating System Configuration dialog.
*----------- Change Device Group / Operating System Configuration ------------*
| Row 1 of 1 |
| Command ===> ___________________________________________ Scroll ===> PAGE |
| |
| Select OSs to connect or disconnect devices, then press Enter. |
| |

HCD applies the OS related changes to all selected devices,
if a user performs an explicit action (for example, Select (connect/change) or Disconnect from OS, see next step). You might
need to also disconnect from those operating systems, which are not
shown as connected (status is shown only for the first device) to
ensure, that all selected devices are disconnected.
- If you want to disconnect the selected device group(s)
from specific operating systems, select those operating systems and
action Disconnect from OS (action code n )
from the context menu.
Otherwise, select the
operating system to which you want to attach the group of devices
and the Select (connect/change) action
from the context menu (or action code s ). HCD
displays the following dialog:
*----------------- Define Device Group Parameters / Features -----------------*
| Row 1 of 4 |
| Command ===> ___________________________________________ Scroll ===> PAGE |
| |
| Specify or revise the values below. |
| |

- You accomplish the change by accepting the default values or by
changing the Value entries and pressing the Enter key.
The specified device parameters/features are applied to all devices
of the group.
Changing the DYNAMIC, LOCANY or OFFLINE parameter of a group
of devices
You can change the DYNAMIC, LOCANY or OFFLINE parameter
of a group of devices using the Attribute
group change action. This function helps you to change parameters
for a group of devices without having to use the Change action
for each device individually.
This function can only be invoked from the I/O Device List accessible
from the Operating System Configuration List.
- On the Primary Task Selection panel, select Define, modify,
or view configuration data and on the resulting panel the object Operating system configurations.
- Select an operating system and select the Work
with attached Devices action from the context menu (or action
code u ). HCD displays the I/O Device List.
- Select one or more devices on the I/O Device List and the Attribute Group change action from the context
menu (or action code e ). HCD displays the Attribute
Group Change panel:
*----------------------- Attribute Group Change ------------------------*
| |
| |
| For all devices in the selected group, choose whether ... |
| |
| __ 1. Allow dynamic configuration ........... DYNAMIC=YES |
| 2. Do not allow dynamic configuration .... DYNAMIC=NO |
| 3. UCB can reside in 31 bit storage ...... LOCANY=YES |
| 4. UCB can not reside in 31 bit storage .. LOCANY=NO |
| 5. Device is set offline at IPL .......... OFFLINE=YES |
| 6. Device is set online at IPL ........... OFFLINE=NO | Select
the appropriate parameter.
HCD only changes the single parameter for all devices of
the group, leaving the other parameters/features of the group unchanged.
Changing type/model of a group of devices
You can change the type or model for a group of devices using the Device type group change action. However,
you have to make sure that all devices to be changed in one step have
the same device type and model. The control units the devices are
attached to, have to support the attachment of the new device type
as well, and required parameters have to be identical. The new device
type has to be supported by the same operating system type.
- Select one or more devices on the I/O Device List.
- Use the Device type group change action
from the context menu (or action code t ). HCD displays
the Device Type Group Change panel.
*----------------- Device Type Group Change -------------------------*
| |
| |
| Specify a new device type-model. |
| |
| Current device type-model . : 3380 |

*--------------------------------------------------------------------*
Specify
a new device type-model.
Changing the subchannel set placement for a group of devices
You can change the placement of PAV alias devices any time, for
example, if you want to migrate PAV alias devices into a subchannel
set of a new processor. From the I/O Device List showing device groups
or single devices, use action Subchannel Set
ID group change from the context menu (or action code m ).
HCD displays the following dialog where you can specify the new ID
of the subchannel set.
