Below describes examples that include (from the
HP-UX shell):
a command successfully
executed
a command not executed
due to the flexible administrative capability feature
adding a virtual partition
to the designated-admin virtual partition list
deleting a virtual partition
from the designated-admin virtual partition list
listing the virtual partitions
in the designated-admin virtual partition list
changing the flexible
administrative capability password
determining whether you
are in flexible administrative capability
For this section, let’s assume we have
the virtual partitions winona1, winona2, and winona3.
A Command Successfully Executed |
 |
Because winona1 is in the designated-admin virtual
partition list. We can execute a command from winona1 that alters
winona2:
winona1# vparmodify -p winona2 -a cpu::1 |
Note that you will not see any flexible administrative
capability messages when flexible administrative capability is allowed;
you will only see flexible administrative capability messages when
access is denied.
A Command Not Executed Due to the Flexible Administrative Capability
Feature |
|
However, because winona2 is not in the designated-admin
virtual partition list. We cannot successfully execute a command from
winona2 that alters another partition:
winona2# vparmodify -p winona1 -a cpu::1
vparmodify: Error: Only Designated-Admin virtual partitions can perform this operation on winona1.
winona2# vparmodify -p winona3 -a cpu::1
vparmodify: Error: Only Designated-Admin virtual partitions can perform this operation on winona3. |
Note that if the target partition is the local
virtual partition, then the partition is only altering itself and
not altering another partition, so this will be allowed.
winona2# vparmodify -p winona2 -a cpu::1 |
Adding a Virtual Partition to the Designated-admin Virtual
Partition List |
|
If we want the non-designated-admin virtual partition
winona2 to be able to alter other virtual partitions, we need to add
it to the designated-admin virtual partition list. This can be done
from any virtual partition, but you will need to know the flexible
administrative capability password.
winona2# vparadmin -a winona2
password:
Virtual partition winona2 is added to the Designated-Admin virtual partitions list. |
Deleting a Virtual Partition to the Designated-admin Virtual
Partition List |
|
If later we want to remove winona2 from the designated-admin
virtual partition list, we can do this from any virtual partition:
winona1# vparadmin -d winona2
Password:
Virtual partition winona2 is deleted from the Designated-Admin virtual partitions list. |
Listing the Virtual Partitions in the Designated-admin Virtual
Partition List |
|
We can verify that winona2 has been removed from
the designated-admin virtual partition list. This can be performed
from any partition.
winona1# vparadmin -l
---------- Designated-Admin virtual partitions ----------
winona1 |
Only winona1 is displayed as a designated-admin
virtual partition. Since winona2 (and winona3) are not in the list,
they are not designated-admin virtual partitions.
Changing the Flexible Administrative Capability Password |
|
We can change the flexible administrative capability
password with the vparadmin -C command. Note that
there is no -C option in the monadmin command, although you will be asked for a new password when you
set the mode from OFF to ON.
The vparadmin -C command can
be executed from any virtual partition; you will need to know the
old password to be able to change the password.
winona2# vparadmin -C
Old password:
New password:
Re-enter new password:
The vPar flexible administrative password successfully changed. |
Determining whether Flexible Administrative Capability is ON
or OFF |
|
When you are within a Unix shell, the easiest
method to determine whether the flexible administrative capability
mode is ON (enabled) is to use the vparadmin command.
When you are not in flexible administrative capability,
you will receive the “disabled” message:
# vparadmin
The virtual partition flexible administrative capability is disabled. |
When you are in flexible administrative capability,
you will receive the “enabled” message:
# vparadmin
The virtual partition flexible administrative capability is enabled. |
