Deleting Classes, Devices, Paths, and Volumes
There are four IO configurator commands that you use to delete objects
from the configuration: DCLASS, DDEV, DPATH, and DVOL. They are defined
in the table below and explained in the following sections.
--------------------------------------------------------------------------------------------
| | |
| Parameter | Definition |
| | |
--------------------------------------------------------------------------------------------
| | |
| DCLASS | Removes one or more class names from the system. |
| | |
--------------------------------------------------------------------------------------------
| | |
| DDEV | Removes a specific device, range of devices, all products of a |
| | given product identification, all devices of a given type, or all |
| | devices of a given class name. |
| | |
--------------------------------------------------------------------------------------------
| | |
| DPATH | Deletes an I/O path and all the I/O paths below it in the |
| | configuration. |
| | |
--------------------------------------------------------------------------------------------
| | |
| DVOL | Deletes a volume member from the system configuration. |

--------------------------------------------------------------------------------------------
To delete classes
Use the DCLASS command (abbreviated DC) to delete class names from the
configuration. To delete a class, at the IO configurator prompt (io>),
enter:
io>DCLASS classname
DCLASS has the following parameter:
DCLASS (DC) {[CLASS =] classname}
CLASS is a repeated parameter that identifies device class names. Class
names are limited to eight characters and the first must be a letter.
You cannot delete the DISC, CONSOLE, or TAPE classes.
To delete a class.
To delete a class name, enter DCLASS and the class name. For example, to
delete EPOC, enter:
io>DCLASS EPOC
To delete multiple classes.
Specify multiple classes by enclosing them with parentheses and
separating each class with commas or spaces. To delete EPOC and FASTLP,
enter:
io>DCLASS (EPOC,FASTLP)
If the class does not exist, SYSGEN displays an error message.
To delete devices
Use the DDEV command (abbreviated DD) to delete a device. You cannot
delete the system disk (LDEV 1) or the system console (LDEV 20).
1. Start SYSGEN and at the prompt (sysgen>), enter:
sysgen>I/O
2. At the IO configurator prompt (io>), enter:
io>DDEV parameters
DDEV has the following parameters:
{[LDEV =] #/#,#,... }
DDEV (DD) {[ID =] deviceid }
{[TYPE =] devicetype}
{[CLASS =] classname}
You must enter at least one parameter and the specified device must exist
in the current configuration or SYSGEN will issue a warning. Other
errors that occur are typically due to improper entry of a logical
device, a range, or improper value for a positional parameter.
To delete devices by LDEV number.
You can use the LDEV parameter to delete one device or a range of
devices. For example, to delete logical device 123, enter:
io>DDEV LDEV=123
Or, to delete devices 10, 11, 12, and 13, enter:
io>DDEV LDEV=10/13
To delete devices by product ID.
You can use the ID parameter to delete all devices with a given product
identification number. If no devices meet the criteria, SYSGEN issues a
warning.
For example, to delete all products with the product ID HP2932A, enter:
io>DDEV ID=HP2932A
To delete devices by type.
You can use the TYPE parameter to delete all devices of a given type,
either those supported by Hewlett-Packard or unsupported devices.
To delete all devices not supported by Hewlett-Packard, enter:
io>DDEV TYPE=USER
If you specify a Hewlett-Packard-supported device, SYSGEN removes all
devices of that type.
To delete devices by class.
You can use the CLASS parameter to delete all devices with the given
class name as well as the class name itself. If the class you specify
does not exist, SYSGEN issues a warning.
For example, to delete all LP devices and the device class LP, enter:
io>DDEV CLASS=LP
CLASS is a repeated parameter.
To delete paths
Use the DPATH command (abbreviated DP) to delete an I/O path and,
optionally, all I/O paths below it from the configuration. If there are
I/O paths below the one you are deleting, SYSGEN prompts you before
deleting them with this question:
I/O path specified has pending devices,
want to delete all of them (yes/no)?
If an I/O path is currently used by a configured device, SYSGEN issues an
error and does not delete the path.
1. Start SYSGEN and at the prompt (sysgen>), enter:
sysgen>io
2. At the IO configurator prompt (io>), enter:
io>DPATH devicepath
DPATH has the following parameter:
DPATH (DP) {[PATH =] devicepath}
To delete a configured path with no associated devices, enter DPATH and
the path. For example, to delete a path on a Series 925 through 949 or a
Series 958 system, enter:
io>DPATH 4.2
To delete a path on a Series 950 through 980 system, enter:
io>DPATH 2/8.2
To delete volumes
Use the DVOL command (abbreviated DV) to remove a volume from the
configuration. To implement the change, you must create a system load
tape with the configuration and then use it to do an INSTALL. To delete a
volume, at the IO configurator prompt (io>), enter:
io>DVOL volumemembername
DVOL has the following parameters:
DVOL (DV) {[VNAME =] volumemembername}
To delete the volume named MEMBER2 from the list of volumes, enter:
io>DVOL MEMBER2
