Purpose
Renames a device.
Description
The rendev command enables
devices to be renamed. The device to be renamed, is specified with
the -l flag, and the new desired name is specified with the -n flag.
The
new desired name must not exceed 15 characters in length. If the name
has already been used or is present in the /dev directory,
the operation fails. If the name formed by appending the new name
after the character r is already used as a device name, or appears
in the /dev directory, the operation fails.
If
the device is in the Available state, the
rendev command must
unconfigure the device before renaming it. This is similar to the
operation performed by the
rmdev –l Name command. If the unconfigure
operation fails, the renaming will also fail. If the unconfigure succeeds,
the
rendev command will configure the device, after renaming
it, to restore it to the Available state. The
–u flag may be
used to prevent the device from being configured again after it is
renamed.
Note: Disk drive devices that are members of the root volume
group, or that will become members of the root volume group (by means
of LVM or install procedures), must not be renamed. Renaming such
disk drives may interfere with the ability to recover from certain
scenarios, including boot failures.
Some devices may
have special requirements on their names in order for other devices
or applications to use them. Using the rendev command to rename
such a device may result in the device being unusable.
Note: To
protect the configuration database, the rendev command cannot
be interrupted once it has started. Trying to stop this command before
completion, could result in a corrupted database.
Flags
| Item |
Description |
|---|
| -l Name |
Specifies the device, indicated by the Name parameter,
to be renamed in the customized devices object. |
| -n NewName |
Specifies the new name, indicated by the NewName parameter,
to be assigned to the device. |
| -u |
Optional flag, which indicates that the device
is not to be configured after it is renamed. |
Examples
- To rename disk hdisk5 to hdisk2, enter:
rendev -l hdisk5 -n hdisk2
- To rename disk hdisk3 to ootvg, enter:
rendev -l hdisk3 -n ootvg
The second command fails because
ootvg appended to
r results
in the name
rootvg, which conflicts with the rootvg volume
group name.
