System Administrator's Quick Reference Guide
Deleting Classes, Devices, and Paths
The I/O configurator commands DCLASS, DDEV, DPATH, and DVOL remove
objects from the system configuration.
Deleting Classes
The DCLASS command deletes class name(s) from the configuration. DCLASS
has the following parameter:
DCLASS (DC) [CLASS =] classname
To delete a class name or names, enter DCLASS and the class name:
io>DCLASS classname
Specify multiple classes by enclosing them with parentheses and
separating each class with commas:
io>DCLASS (classname1,classname2)
Deleting Devices
The DDEV command deletes the devices which meet the specified criteria.
You must specify a parameter or SYSGEN issues a warning. SYSGEN does not
permit the system disk or system console to be deleted. Those devices
must always be present in the specified locations (LDEVs 1 and 20
respectively). DDEV has the following parameters:
DDEV (DD) [ [LDEV =] device range ]
[ [ID =] product id ]
[ [TYPE =] USER ] [ device type ]
[ [CLASS =] classname ]
Enter any one of the parameters, depending on what you want to delete.
For example:
io>DDEV 10/13 ** Delete devices 10-13. **
io>DDEV (12/13,22) ** Delete devices 12-13, and 22. **
io>DDEV ID=HP2932A ** Keyword parameter **
io>DDEV,,,FASTLP ** Positional Parameter **
Deleting Paths
The DPATH command (abbreviated DP) deletes an I/O path and all I/O paths
below it from the configuration. If an I/O path is currently used by a
configured device, it is not deleted, and SYSGEN issues a warning.
If there are I/O paths below the specified one, SYSGEN asks whether or
not they may be deleted as well. If you answer NO, SYSGEN does not
delete the specified I/O path.
DPATH has the following parameter:
DPATH (DP) [PATH =] device path
To delete a configured path with no associated devices, enter DPATH and
the path:
io>DPATH 4.2 ** Series 925/935 **
or
io>DPATH 2/8.2 ** Series 950/955 format **
This path and subsequent paths are deleted automatically as long as there
are no associated devices.
If the path has an associated device, SYSGEN issues an error message:
io>DP 4.2
**error**iopath is currently referenced by a configured ldev, it cannot be deleted
Deleting Volumes
The DVOL command is reserved for use by Hewlett Packard Service Personnel
only.
