memory increase in vPar

[silusan]

Increased memory in a vPar by 8GB

dmesg grep physical shows old memory.
whereas swapinfo output shows new increased memory.
Can you please help me understand why is it so?

Now whats the actual RAM in this vPar?

Do we need any reboots?
or is it already increased but dmesg isnt updated?

# swlist | grep -i "integrity vm"
  VMGuestLib                    A.03.50.0803   Integrity VM Guest Support Libraries
# uname -a
HP-UX B.11.31 U ia64 0051955873 unlimited-user license

vparstatus -A showed

[Available ILM (MB)]:  58451

vparmodify - increased the vpar memory by 8GB

Then vparstatus -A shows :

[Available ILM (MB)]:  51451

earlier :

# dmesg |grep -i physical
    physical page size = 4096 bytes, logical page size = 4096 bytes

After increasing the memory by 8GB:

dmesg | grep -i physical doesnt change..but everything else(regarding memory) changes.

# dmesg |grep -i physical
    physical page size = 4096 bytes, logical page size = 4096 bytes

Dmesg gives you content of kernel message buffer, i.e. the information in there doesn't change. The memory line is printed at boot time so unless you reboot the message was already printed and won't reflect new size.

Note that 'integrity vm' has nothing to do with vPars, these are different virtualization technologies.
