Hardware Status Legend
In several views, the status of each displayed hardware component is represented
by an icon attached to the component. The meaning of each icon is identified by
the hardware status legend at the bottom right of the view (for example, see
overview, Figure 1.).
Some of these status icons are also used in tables displayed by several
Partition Manager actions (for example, show
complex details).
Unknown Status
The Unknown status indicator (
) is
displayed when Partition Manager cannot read information about cells, I/O chassis, or
nPartitions from the local service processor, or cannot
obtain this information from the remote WBEM services provider.
This does not necessarily indicate an error condition. For example, some cell
information (such as memory configuration) cannot be obtained if the cell is
powered off or has not completed its power-on self-test.
Unknown status may also be caused by an error condition or a lock contention
problem. In some circumstances, the status indicator will be followed by the
reason for the unknown status, as shown below.
-
Read Error
A read error may be a transient condition. Repeating the action may
succeed in retrieving the information.
-
Locked
Read and write locks are used to synchronize access to complex and nPartition information.
Usually, lock contention is a transient condition that is
automatically resolved. When a lock is held for an abnormally long time (for example,
when the process that holds the lock terminates abnormally), you can forcibly release it.
Stale locks are automatically broken after they have been held for 25 minutes.
Refer to the Lock Contention message
for more information.
Unknown status may also be shown when retrieving information from a remote
nPartition, if the WBEM user name and password are not known on the remote
nPartition. Refer to user
authentication for more information.
iCAP and Partition Manager
If the complex contains Instant Capacity
(iCAP) components (CPUs, cells, or memory) some hardware
components may be displayed by Partition Manager as Active/OK even
though they cannot be used. For example, Partition Manager displays the hardware state
of CPUs rather than the operating system's state for those CPUs. As a result,
CPUs shown to be active by Partition Manager may actually be inactive in the operating
system.
To see how many CPUs are active in an operating system, use either the
top(1)
command or
icod_stat(1M).
Similarly, cells that are assigned to nPartitions but have their Use On
Next Boot flag set to “No” may be iCAP
cells (possibly containing iCAP memory). Unassigned cells may also be iCAP cells.
Actions related to assigning or activating cells via Partition Manager may fail if the result
of such assignment or activation would require the activation of unlicensed iCAP
components. Use
icod_stat(1M)
to get the current iCAP status of the complex, including the quantities of
unlicensed CPUs, cells, and memory and the distribution of the iCAP CPUs among
nPartitions and unassigned cells.
The nPartition Configuration Privilege does
not control provisioning of iCAP processors.
