Configuring And Deconfiguring Memory (Dimms); Enabling Hyper-Threading For An Npartition - HP Rp7410 - Server - 0 MB RAM Administrator's Manual

Example 7-3 Enabling Hyper-Threading for an nPartition
Shell> cpuconfig threads
cpuconfig: Threads are turned off.
Shell>
Shell> cpuconfig threads on
cpuconfig: Threads will be on after a reset.
Shell>
The EFI Shell cpuconfig threads command indicates that Hyper-Threading currently
1
is disabled (turned off) for the nPartition.
This EFI Shell command configures Hyper-Threading to be enable after the nPartition is
2
reset.
Disabling Hyper-Threading for an nPartition
following methods and then reset the nPartition whose Hyper-Threading status you have changed:
• From the EFI Shell: cpuconfig threads off
• From HP-UX: setboot -m off
• Using the Enhanced nPartition Commands: parmodify -pn -T n, where n is the nPartition
number.
• Using Partition Manager: Perform the Modify nPartition task and deselect the Enable
Hyper-Threading check box on the Configure Memory tab.
You must reset an nPartition after changing its Hyper-Threading status.

Configuring and Deconfiguring Memory (DIMMs)

You can configure and deconfigure memory by using any one of the following procedures:
• "Configuring and Deconfiguring Memory (BCH Menu)" (page 220)
• "Configuring and Deconfiguring Memory (EFI Shell)" (page 221)
You can configure and deconfigure memory modules (DIMMs) from any cell that is assigned to
an nPartition. Deconfiguring memory causes it to not be available for use by the cell or its
nPartition.
Whenever you configure or deconfigure memory, you must reboot the corresponding nPartition
for the configuration change to take effect.
NOTE:
DIMMs operate either in ranks of four or echelons of two, depending on memory
architecture of the server. When you deallocate a DIMM, all other DIMMs in the rank or echelon
also will not be used the next time the nPartition boots.
Each rank or echelon is numbered (0, 1, 2, and so on up to hexadecimal number F as needed).
The DIMMs in the rank or echelon are lettered (A to D). For example, rank 0 includes DIMMs
0A, 0B, 0C, and 0D; echelon 1 has DIMMs 1A and 1B.
Procedure 7-14 Configuring and Deconfiguring Memory (BCH Menu)
From the BCH Service Menu, use the DIMMDEALLOC command to configure or deconfigure
memory modules (DIMMs) in cells assigned to the local nPartition. The BCH Menu is available
only on HP 9000 systems.
