rmpath Command
Purpose
Removes from the system a path to an MPIO-capable device.
Syntax
rmpath { [ -dev Name ] [ -pdev Parent ] [ -conn Connection ] } [ -rm ]
Description
The rmpath command unconfigures, and possibly undefines,
one or more paths associated with the specified target device (-dev Name). The set of paths that is removed
is determined by the combination of the -dev Name, -pdev Parent and -conn Connection flags. If the command
will result in all paths associated with the device being unconfigured or
undefined, the command will exit with an error and without unconfiguring or
undefining any path. In this situation, rmdev command
must be used instead to unconfigure or undefine the target device itself.
The default action unconfigures each specified path, but does not completely
remove it from the system. If the -rm flag is specified,
the rmpath command unconfigures (if necessary) and removes,
or deletes, the path definition(s) from the system.
When the rmpath command finishes, it displays a status
message. When unconfiguring paths, it is possible for this command to be able
to unconfigure some paths and not others (e.g., paths that are in the process
of doing I/O cannot be unconfigured).
The rmpath command provides status messages about
the results of operation. Messages in one of the following formats will be
generated:
- path [ defined | deleted ]
- This message is displayed when a single path was successfully unconfigured
or undefined. If the path is successfully configured the message path available
displays. If the path is not successfully configured and there is no explicit
error code returned by the method, the message path defined displays.
- paths [defined | deleted]
- This message is displayed if multiple paths were identified and all
paths were successfully unconfigured or undefined. If the -rm flag is not specified, the message would be paths defined. If the -rm flag is specified, the message would be paths deleted.
- some paths [ defined | deleted ]
- This message is display if multiple paths were identified, but only
some of them were successfully unconfigured or undefined. If the -rm flag is not specified, the message would be some paths defined. If
the -rm flag is specified, the message would be some
paths deleted.
- no paths processed
- This message is generated if no paths were found matching the selection
criteria.
Flags
| -rm |
Indicates that the specified paths are to be deleted
from the system. |
| -dev Name |
Specifies the logical device name of the target device
whose path is to be removed. The paths to be removed are qualified via the -pdev and -conn flags. |
| -pdev Parent |
Indicates the logical device name of the parent device
to use in qualifying the paths to be removed. Since all paths to a device
cannot be removed by this command, either this flag, the -conn flag, or both must be specified. |
| -conn Connection |
Indicates the connection information to use in qualifying
the paths to be removed. Since all paths to a device cannot be removed by
this command, either this flag, the -pdev flag, or both
must be specified. |
Exit Status
See Virtual I/O Server command exit status.
Examples
- 1. To unconfigure the path from scsi0 to hdisk1 at connection 5,0, type:
rmpath -dev hdisk1 -pdev scsi0 -conn "5,0"
The message generated would be similar to:
path defined
- To unconfigure all paths from scsi0 to hdisk1, type:
rmpath -dev hdisk1 -pdev scsi0
If all paths were
successfully unconfigured, the message generated would be similar to:
paths defined
However, if only some of the paths were successfully unconfigured,
the message would be similar to:
some paths defined
- To undefine the path definition between scsi0 and hdisk1 at connection 5,0, type:
rmpath -rm -dev hdisk1 -pdev scsi0 -conn "5,0"
The message generated would be similar to the following:
path deleted
- To unconfigure all paths from scsi0 to hdisk1, type:
rmpath -rm -dev hdisk1 -pdev scsi0
The message
generated would be similar to:
paths deleted
