vPars question

Paul Goslin Rae McCarth — Wed, 30 Aug 2006 14:04:42 GMT

Help! I have a question about vPars. I need to create 6 partitions. I have a RP7410 with 2 cell board, 6 cpu's (2 on cell0 and 4 on cell 1), 6 lan cards, 6 fiber cards, 32Gb of memory, a VA7400 disk array with 1.2 Tb usable disk space. I think the problem is that the VA is directing all of the disk space thru the hardware path 0/0/10/0/0.1.0.0 so when I created the 6 luns via SDM they now appear as follows:

0/0/10/0/0.1.0.0.0.0.1
0/0/10/0/0.1.0.0.0.0.2
0/0/10/0/0.1.0.0.0.0.3
0/0/10/0/0.1.0.0.0.0.4
0/0/10/0/0.1.0.0.0.0.5
0/0/10/0/0.1.0.0.0.0.6

In the docs it seems to suggest that I need specify unique I/O Paths and Boot Path. But I don't think this is possible because the VA problem. Any suggestions!

Thank you - Rae McCarthy

So how many Hard partitions did you created already?

Re: vPars question

Paul Goslin Rae McCarth — Wed, 30 Aug 2006 15:29:26 GMT

I did not setup any nPartitions because the cpu's are: 2 on cell 0 and 4 on cell 1.

Then create one Npar combining two cells and then create 6 vpars. is this what you looking for?

I must be not understanding -
I thought a system was already 1 hard partition. Are you saying that I have to create the system as 1 nPartition?

It seems you have Genesis partition. correct which was shipped with it? or did you created it?

Make sure that you have all required Npar and Vpar software installed and in configured state.

you can define resources using vparcreate command including cpu, mem, io.

Are you looking for the help to do HOW-TO ?

I not know what Genesis means. And I do need HOW-TO help.

Thanks

Hi,

Do you have HPUX installed right now?
If you do, could you gave information below:

# nparstatus

Do you want to install the os of the vpar on the VA7400? It would be dangerous because every vPar will see all 6 LUN you created on the VA7400

guide to nPartitions:
http://www.docs.hp.com/en/5991-1247/5991-1247.pdf

guide to vPar:

regards,
Sandy

Sandy,

I installed HPUX 11.11 on the local disk drive. I then installed npars, vpars, ignite, etc. I'm assuming that I now need to create the 6 vpars using the VA7400 disk space. I will attached the output of /usr/lib/npar/parstatus.

Re: vPars question

IT_2007 — Thu, 31 Aug 2006 08:26:57 GMT

would you please run ioscan -fn;insf -e so that devices get created for attached VA7400.

also post output of ioscan -fnCdisk

output shows two HP 73.4GB disks for paths:
1/0/0/3/0.6.0 and 1/0/1/0/0/1/1.6.0
Are these hooked to VA7400 or local?

Also, you can start like this.

convert existing Npar to vpar using vparcreate command. Need to know what is boot disk and alternate boot disk, how many cpu's you want to bind, how much memory you want to allocate and what other resources like Fibre channel cards, NIC cards etc.. Once you have that information you can issue the command:

vparcreate -p -a cpu:::Min:Max -a mem:::totalmem-gb -a io:primary-bootpath -a io:alt-boot-path \
-a io:fibrecard1 -a io:fibrecard2 \
-a io:boot-diskpath:BOOT -a io:alt-boot:ALT

and then make sure that you issue following commands on boot disks.

mkboot -a "hpux -lq /stand/vpmon -a" /dev/dsk/cxtydz which is primary boot disk
issue same command for alternate boot disk so that when you reboot it will bring up all vpars.

Once you bring up 1st vpar, you can continue to create multiple vpars at one shot.
vparstatus -v will shows all vpar's info.
To boot other vpar's from 1st vpar, use:
1stvpar:> vparboot -p <2ndvpar>
1stvpar:> vparboot -p <3rdvpar>

I have attached the ioscan -fnC disk output.
The 73Gb disks are local drives on the RP7410 not on the VA7400.

Re: vPars question

IT_2007 — Thu, 31 Aug 2006 09:12:33 GMT

Ok. If you know all the details which I asked above for cpu, memory, io's etc.. then you can create them using vparcreate command.

Your question was how to specify unique IO paths.. correct? They are unique, for ex: 0/0/10/0/0.1.1.0.0.0.4 is related to disk /dev/dsk/c38t0d4. If this going to be a boot disk then

vparcreate -p ..... -a io:0/0/10/0/0.1.1.0.0.0.4:BOOT

like that so on...

Do you think there is a issue with the VA directing all of the disk space thru the hardware path 0/0/10/0/0.1.0.0? When I created the 6 luns via SDM they now appear as follows:

0/0/10/0/0.1.0.0.0.0.1
0/0/10/0/0.1.0.0.0.0.2
0/0/10/0/0.1.0.0.0.0.3
0/0/10/0/0.1.0.0.0.0.4
0/0/10/0/0.1.0.0.0.0.5
0/0/10/0/0.1.0.0.0.0.6

Re: vPars question

IT_2007 — Thu, 31 Aug 2006 09:15:39 GMT

No. There won't be an issue.

Re: vPars question

Paul Goslin Rae McCarth — Thu, 31 Aug 2006 10:09:52 GMT

Do I have the correct command?

vparcreate â p cms01 â a cpu:::1:1 â a cpu:0/10 â a mem::4096 â a io:0/0/10 â a io:1/0/1/0/0/4/0 â a io:10/0/0.1.0.0.0.0.1:BOOT

Thank you for help.

Re: vPars question

Paul Goslin Rae McCarth — Thu, 31 Aug 2006 10:15:26 GMT

I'm not sure why the text looks odd. Here it is again:

vpcreate -p cms01 -a cpu:::1:1 -a cpu:0/10
-a mem:4096 -a io:0/0/10 -a o:1/0/1/0/0/4/0
-aio:10/0/0.1.0.0.0.0.1:BOOT

Re: vPars question

IT_2007 — Thu, 31 Aug 2006 14:24:27 GMT

You said....

vpcreate -p cms01 -a cpu:::1:1 -a cpu:0/10
-a mem:4096 -a io:0/0/10 -a o:1/0/1/0/0/4/0
-aio:10/0/0.1.0.0.0.0.1:BOOT

Something isn't correct..

do this way. to convert existing one, give me lvlnboot -v so that I tell you exact syntax.
it would be like:

vparcreate -p cms01 -a cpu::1:1 -a mem:::4096 -a io:0/0/10 -a io:1/0/1/0/0/4/0 \
-a io:10/0/0.1.0.0.0.0.1:BOOT \
-a io:10/0/0.1.0.0.0.0.2:ALT
