HPVM guest dynamic memory managment software

[ Edited ]

Hello Expert,

 

 

 

I just instaled the HPGUES Memory managment software & run the below commands

 

# mknod /dev/hpvmdynmem c 171 0

 

# ll /dev/hpvmdynmem

crw-r--r--   1 root       sys        171 0x000000 Jul 14 09:16 /dev/hpvmdynmem

 

# kcmodule hpvmdynmem

ERROR:   There is no module named 'hpvmdynmem'.

 

# cat </dev/hpvmdynmem

sh: /dev/hpvmdynmem: Cannot find or ope

 

Please let me know the reason & solution behind this....

 

Below is the solution provide by the SAP

Issue is there : is a process called SAP OS collector process was generating to many child procese.We concern this to SAP

& the provided the below solution

( My VM version is B.04.30)

 

Dear Customer,
It is a known issue at HP.
First of all refer to SAP note #918279:
[...]
IMPORTANT: When running inside a "HP Integrity Virtual Machines"
(HPVM) guest, the latest HPVM guest library patches must be installed
on the guest system. Otherwise the saposcol process might hang, when
collecting data.
Update the above-mentioned library AND also saposcol to the latest
version ( V3.1.1, see SAP note #918279).
In addition to this , HP gave following answer to a similar issue:
================================================================
CAUSE:
Collected the below outputs to verify .
# ll /dev/hpvmdynmem
# lsdev
# kcmodule hpvmdynmem
The hpvmdynmem device file is stale. It points to driver 144 which is
fcoc_fcp
and not to hpvmdynmem at 171.
Answer/Solution
FIX:
To remove and re-create the /dev/hpvmdynmem file
#rm /dev/hpvmdynmem
#mknod /dev/hpvmdynmem c 171 0
One can check if it works fine by doing:
# cat </dev/hpvmdynmem
It should printout some stats.

 

I copied the software from host to guest the path of the host is :/opt/hpvm/guest-images/hpux/11iv3/hpvm_guest_depot.11iv3.sd

The guest path is :/var/hp/depot/ hpvm_guest_depot.11iv3.sd .

 

I installed this S/W on the guest .

 

Therefore when I run the below commands no output shown e.g

 

#mknod /dev/hpvmdynmem c 171 0

# ll /dev/hpvmdynmem

# kcmodule hpvmdynmem

# cat </dev/hpvmdynmem

 

Request you to please suggest me on this.

 

Thanks & have a great day ahead.

Regards,

Vishal

Re: HPVM guest dynamic memory managment software

So the errors would suggest you don't have the VM guest libraries installed in your VM (or v6.x vPar).

 

What version of HPVM/vPars are you using?

Re: HPVM guest dynamic memory managment software

Did you install the VM guest kit inside the VM guest?  This is required to use the Dynamic Memory feature.
