You can configure and deconfigure cells by using any one
of the following procedures: You can deconfigure (make inactive) a cell that is assigned
to an nPartition by setting its use-on-next-boot value to "n" (do not use).
This causes the cell to remain assigned to the nPartition, but the cell will
be inactive the next time its nPartition boots, meaning the cell hardware
resources will not be used. Whenever you configure or deconfigure cells, you must reboot
the corresponding nPartition for the configuration change to take effect. | | | |  | NOTE: Configuring and deconfiguring cells may be restricted based
on any Instant Capacity contract for the server complex. | | | | |
Procedure 7-8 Configuring and Deconfiguring Cells (BCH Menu) From the BCH Configuration Menu use the CELLCONFIG command
to configure and deconfigure cells assigned to the local nPartition. The BCH
Menu is available only on HP 9000 systems. Access the BCH
Main Menu for the nPartition whose cells you want to configure or deconfigure. Login to the service processor (MP or GSP) and enter CO to
access the Console list. Select the nPartition console. When accessing the
console, confirm that you are at the BCH Main Menu (the Main
Menu: Enter command or menu> prompt). If at a BCH menu
other than the Main Menu, then enter MA to return to the
BCH Main Menu. Enter CO to
access the Configuration Menu. From the BCH
Configuration menu, use the CELLCONFIG command to list
or set the use-on-next-boot value for each cell. To list the use-on-next-boot values
for all cells in the nPartition, issue the CELLCONFIG command
with no arguments. To change a cell use-on-next-boot
value, issue the following command: CELLCONFIG cell [ON|OFF] where cell is the cell number, ON sets
the cell use-on-next-boot value to "y" (yes, do use the cell), or OFF sets
the cell use-on-next-boot value to "n" (no, do not user the cell). A cell that boots with a "y" (ON)
use-on-next-boot value is permitted to rendezvous and join its nPartition,
thus becoming an active cell whose resources are used. A cell that boots with a "n" (OFF)
use-on-next-boot value does not rendezvous and thus becomes an inactive cell
whose resources are not used by its nPartition, although the cell still is
assigned to its nPartition.
Reboot the nPartition
to use the cells' new use-on-next-boot settings. If
you have changed any cell use-on-next-boot settings for the nPartition then
reboot the nPartition in either of two ways: Use the REBOOT command
at the BCH interface to perform a reboot. If you
have only changed cell configurations from ON to OFF,
then perform a reboot using the REBOOT command. Any cells
set to not be used will still be assigned to the nPartition but will not be
used (will not rendezvous) in the nPartition. Use the RECONFIGRESET command
at the BCH interface to put the nPartition in the shutdown for reconfig state,
then use the BO command at the service processor Command
menu to boot the nPartition. If you have changed
any cell from OFF ("n", do not use on next
boot) to ON ("y", use the cell on next boot),
then you must perform these two tasks; this resets and reconfigures the nPartition
and boots it.
Exit the console
and service processor interfaces if finished using them. To
exit the BCH environment type ^B (Control-B);
this exits the nPartition console and returns to the service processor Main
Menu. To exit the service processor, type X at the Main
Menu.
Procedure 7-9 Configuring and Deconfiguring Cells (EFI Shell) From the EFI Shell environment, use the use the cellconfig command
to configure or deconfigure cells in the local nPartition. The EFI Shell is
available only on HP Integrity systems. | | | | | NOTE: Use of the cellconfig command at the
EFI Shell is restricted. See the help cellconfig command
for details. | | | | |
Access the EFI
Shell environment for the nPartition whose cells you want to configure or
deconfigure. Login to the service processor (MP or
GSP) and enter CO to access the Console list. Select the
nPartition console. When accessing the console, confirm that you are at the
EFI Boot Manager menu (the main EFI menu). If at another EFI menu, select
the Exit option from the sub-menus until you return
to the screen with the EFI Boot Manager heading. From the EFI Boot Manager menu, select the EFI
Shell menu option to access the EFI Shell environment. Use the cellconfig command
to list or set the configuration setting (the use-on-next-boot value) for
each cell. To list the use-on-next-boot values
for all cells in the nPartition, issue the cellconfig command
with no arguments. To change a cell use-on-next-boot
value, issue the following command: cellconfig cell [on|off] where cell is the cell number, on sets
the cell use-on-next-boot value to "y" (yes, do use the cell), or off sets
the cell use-on-next-boot value to "n" (no, do not user the cell). A cell that boots with a "y" (on) use-on-next-boot
value is permitted to rendezvous and join its nPartition, thus becoming an
active cell whose resources are used. A cell that boots with a "n" (off) use-on-next-boot
value does not rendezvous and thus becomes an inactive cell whose resources
are not used by its nPartition, although the cell still is assigned to its
nPartition.
Reboot the nPartition
to use the cells' new configuration settings. If
you have changed any cell use-on-next-boot settings for the nPartition then
reboot the nPartition in either of two ways: Use the reset command
at the EFI Shell to perform a reboot. If you have
only changed cell configurations from on to off,
then perform a reboot using the reset command. Any cells
set to not be used will still be assigned to the nPartition but will not be
used (will not rendezvous) in the nPartition. Use the reconfigreset command
at the EFI Shell to put the nPartition in the shutdown for reconfig state,
then use the BO command at the service processor Command
Menu to boot the nPartition. If you have changed
any cell from off ("n", do not use on next
boot) to on ("y", use the cell on next boot),
then you must perform these two tasks; this resets and reconfigures the nPartition
and boots it.
Exit the console
and service processor interfaces if finished using them. To
exit the EFI environment type ^B (Control-B);
this exits the nPartition console and returns to the service processor Main
Menu. To exit the service processor, type X at the Main
Menu.
Procedure 7-10 Configuring and Deconfiguring Cells (nPartition Commands) From the command line, use the parmodify -p# -m#... command
to configure or deconfigure a cell by setting its use-on-next-boot attribute
value. You also can use the parstatus -V -c# command
to list attribute details for a specific cell (-c# where # is
the cell number). Login to a system
with the nPartition commands installed. If using
remote administration features to configure and deconfigure cells, you can
login to any system with Enhanced nPartition Commands installed. To list current
cell attribute settings, use the parstatus -C command to
list the use-on-next-boot values for all cells, or use the parstatus
-V -c# command to list all attribute values
for a specific cell (-c# where # is
the cell number) To modify cell
attribute values, use the parmodify -p# -m#... command
and specify the new cell attributes as part of the -m option.
The -m... option differs slightly for the nPartition command
releases. You must specify both the nPartition (-p# where # is the nPartition number) and the cell (-m#... where # is
the cell number). See “Setting Cell Attributes” for
details on modifying cell attributes, including the use-on-next-boot value
that determines whether a cell is configured or deconfigured during the nPartition
boot process. Reboot the nPartition
to use the cells' new configuration (the new use-on-next-boot values). If you have changed any cell use-on-next-boot settings
for the nPartition then reboot the nPartition in either of two ways: Perform a standard reboot (HP-UX: shutdown
-r; Windows: shutdown /r; Linux: shutdown
-r time; OpenVMS: @SYS$SYSTEM:SHUTDOWN with
an automatic system reboot). If you have only changed
use-on-next-boot values from y to n,
then perform a reboot. Any cells set to not be used will still be assigned
to the nPartition but will not be used (will not rendezvous) in the nPartition. Perform a reboot for reconfig (HP-UX: shutdown
-R; Windows: shutdown /r; Linux: shutdown
-r time; OpenVMS: @SYS$SYSTEM:SHUTDOWN with
an automatic system reboot). If you have changed
any use-on-next-boot values from n (do not
use on next boot) to y (use the cell on next
boot), then you must perform a reboot for reconfig to allow the currently
inactive cells to reboot and rendezvous when the nPartition reboots.
Procedure 7-11 Configuring and Deconfiguring Cells (Partition Manager) You can set configure and deconfigure cell by using Partition
Manager to set each cell use-on-next-boot value. When using Partition Manager Version 1.0, select the nPartition
to which the cell belongs, select the Partition Modify Partition action, Change
Cell Attributes tab, select the cell(s), and click Modify
Cell(s). When using Partition Manager Version 2.0, select the nPartition
to which the cell belongs, select the nPartitionModify nPartition action, and then
configure attributes using the Set Cell Options tab. Access Partition
Manager. For details on accessing Partition Manager
or other tools, see “Tools for Managing Hardware”. Select the nPartition
whose cells you want to configure or deconfigure. Initiate the
nPartition modify action. If using Partition Manager
Version 1.0, the PartitionModify
Partition action. If using Partition Manager Version 2.0, select the nPartitionModify nPartition action. Access the Partition
Manager section(s) for configuring cell attributes. From
Partition Manager Version 1.0, select the Change Cell Attributes tab,
then select the cell and click the Modify Cell button.
This enables you to configure the use-on-next-boot value for the selected
cell. From Partition Manager Version 2.0, use the Set
Cell Options tab to configure cell use-on-next-boot values. After changing
attribute values for all the cells you plan to modify, click the OK button. Review all information
presented in the Notes and Warnings, the Summary
of Changes, and the HA Checks tabs. Either cancel
or proceed with the cell attribute changes. Click
the Cancel button to cancel the changes. To proceed with the cell use-on-next-boot changes, click
the Finish button or click the OK button. Reboot the nPartition
to use the cells' new attribute values. If you
have changed any cell use-on-next-boot settings for the nPartition then reboot
the nPartition in either of two ways: Perform a standard reboot (HP-UX: shutdown
-r; Windows: shutdown /r; Linux: shutdown
-r time; OpenVMS: @SYS$SYSTEM:SHUTDOWN with
an automatic system reboot). If you have only changed
use-on-next-boot values from y to n,
then perform a reboot. Any cells set to not be used will still be assigned
to the nPartition but will not be used (will not rendezvous) in the nPartition. Perform a reboot for reconfig (HP-UX: shutdown
-R; Windows: shutdown /r; Linux: shutdown
-r time; OpenVMS: @SYS$SYSTEM:SHUTDOWN with
an automatic system reboot). If you have changed
any use-on-next-boot values from n (do not
use on next boot) to y (use the cell on next
boot), then you must perform a reboot for reconfig to allow the currently
inactive cells to reboot and rendezvous when the nPartition reboots.
