Hi,

If I only have access of VIO managed LPAR and HMC managed LPAR, how can I check which is vio lpar and HMC lpar by logging into it.

I'm not sure I understand this question.

VIO servers don't manage LPARs, they provide virtual resources to LPARs.

HMC's are connected to hardware and are used to manage that hardware.

What is it you're trying to do?

Hi,

May be you are referring to LPARs:
1. with physical IO resources allocated through HMC and
2. with virtual IO resources provided through VIO server (which still has CPU/Memory allocated from HMC)
On the LPAR, run the command lsdev -Cc adapter and if
1. Physical IO resources will be listed as below:
ent0 Available 1L-08 10/100 Mbps Ethernet PCI Adapter II (1410ff01)
ent1 Available 1j-08 10/100/1000 Base-TX PCI-X Adapter (14106902)
fcs0 Available 1H-08 FC Adapter
fcs1 Available 1V-08 FC Adapter
2. Virtual IO resources will be listed as below:
ent0 Available Virtual I/O Ethernet Adapter (l-lan)
vsa0 Available LPAR Virtual Serial Adapter
vscsi0 Available Virtual SCSI Client Adapter

Hope this helps.

I wanted to ask that if i am an end user and if i want to know whether my node is managed by HMC and/or IVM how can i check the same:-

This is the below output of my lpar:-

bash-3.00# lsdev -Cc adapter
ent0 Available Logical Host Ethernet Port (lp-hea)
ent1 Available Logical Host Ethernet Port (lp-hea)
lhea0 Available Logical Host Ethernet Adapter (l-hea)
sissas0 Available 00-08 PCI-X266 Ext Dual-x4 3Gb SAS Adapter
sisscsia0 Available 01-08 PCI-XDDR Dual Channel Ultra320 SCSI Adapter
vsa0 Available LPAR Virtual Serial Adapter

I agree with the other posts but as none of your resources, except the serial adapter, say they are virtual it looks like the LPAR is a HMC managed LPAR with physical resources rather than IVM / VIO resources which would all have 'virtual' in the names.
The vsa0 is the same in either case because it is virtualised from the service processor by the hypervisor / firmware.

Just curious to know: Can a serial adapter be configured to be dedicated to an LPAR (in which case it wouldnt be virtual) or does it always have to be virtual when configured for a LPAR (by virtue of limited serial interfaces on the system)?

You always have a couple of virtual serial adapters, used for console connections from the HMCs.

You can also have physical ports although the ones inbuilt to the POWER system do not work in LPAR mode, you would need the two port serial card or the serial cable breakout box if they still do this (offers 8 or 128 ports I seem to recall).

Note that if you do need to use serial adapters the internal adapters are not full serial adapters and you have to use the PCI card serial adapters for things like POWERHA if want the rs232 heartbeat. Having said that you would normally use disk heartbeat so I am struggling to think of what would need a physical rs232 link these days...

I believe POWER6 IVM allows physical resources to be assigned to an LPAR.
