Re: npar

If it's the first time you create an npar, look at the creation of the genesis partition chap 6

Hi,

# parcreate -P HPES81-4 \
-c 1:base:y:ri:25% \
-I 156.153.207.164 \
-b 1/0/0/3/0.6.0 \
-B

options are
-P PartitionName]
-I IPaddress]
-b PRI boot device
-t HAA boot device
-s ALT boot device
-B boot the new nPar to BCH

For more information you can see man pages of parcreate

Re: npar

Hi,


It is always s good idea if you go through the NPAR admin guide and can understand the power and the flexibility that the HP NPARS are known for: NPAR admin guide

chapter for creating the NPAR

http://docs.hp.com/en/5991-1247B_ed2/ch06s02.html

suggest that you can have whole book downloaded for reference on PDF.

I assume that you are already having a running NPAR with HP-UX running. If then you can do as in Step 2.

If you have a brand new Complex with no NPARs can have a look at Step 1.


Step 1:)In a brand new Complex that has no NPARs configured, First a Genesis NPAR needs to be created and OS installed onto that.
Then use the OS Commands like parcreate/parmodify to create and modify the further NPAR.

Genesis Partion is created using the BCH/EFI command "CC" that is "Change Complex"

2) The other NPARs can then be cretaed and installed using the parcreate command as said by Suraj.

Re: npar

Hi,

CREATING A NEW HARD NPAR




For these instructions and examples, the new nPar will be fhp015g.

Get the DVD address from the CE and have an HP-UX install CD or a boot helper CD mounted.

Use the â parstatus -ACâ command to list all available cells (the unassigned cells) in the server complex.

fhp015a1-root:/root> parstatus -AC

[Cell]
CPU Memory Use
OK/ (GB) Core On
Hardware Actual Deconf/ OK/ Cell Next Par
Location Usage Max Deconf Connected To Capable Boot Num
========== ============ ======= ========= =================== ======= ==== ==
cab1,cell5 power on 8/0/8 64.0/0.0 cab1,bay0,chassis3 yes - -
cab1,cell7 power on 8/0/8 64.0/0.0 cab9,bay1,chassis3 yes - -

You can select any of the cells listed to create the new nPartition; only the cells that are not "absent" are present within the server complex.
All cells that you choose must meet the hardware requirements for nPartitions (for example, they all must have the same firmware revision). The cells also must form an HP-recommended nPartition configuration. At least one cell must have an I/O chassis with core I/O.
Use the â parstatus â V â c#â command on each cell to list cell firmware revision. (# is the global cell number)

fhp015a1-root:/root> parstatus â V â c13
fhp015a1-root:/root> parstatus â V â c15


Use the â parcreate â câ command to create the new nPar. You can specify â c multiple times on one command. The enhanced command is different. Check the HP document site above.

fhp015a1-root:/root> parcreate â c13:base:y:ri â c15:base:y:ri
When parcreate successfully creates a new nPartition, it reports "Partition Created" and reports the nPartition number ("partition number is..."). You will need the partition number for the following parmodify commands. In this case it will be 5.
Use parmodify â p# -r# -r# to specify the core cell choices. A core cell choice is a configured cell which has attached core IO. If the core cell of a partition is deleted then the firmware will select the first core cell choice as the next core cell. One to four core cell choices can be specified.
fhp015a1-root:/root> parmodify â p5 â r13 â r15

Use parmodify â p# -Pâ nParnameâ to name the new nPar.
fhp015a1-root:/root> parmodify â p5 â P â fhp015gâ

Use parstatus â V â p# command to list all details about your newly created and configured nPar.
fhp015a1-root:/root> parstatus â V â p5

Boot your newly-created nPartition past boot-is-blocked to make it active and make its system boot environment available.
Use the BO command at the service processor Command menu to boot the nPartition.
Once the nPartition is booted, you can access its system boot environment through its console. Use the service processor Console menu (enter CO at the service processor Main Menu).
Boot from the DVD and stop at the Ignite main menu (Boot DVD should contain same version of ignite as on chxtil7). Notify the assigned SI person.
