Multiple pconsole processes spawning indefinetly

Leave a comment

By Janpol

Good night everyone, I’ve been trying to make AD authentication work with RBAC and I think I messed my test LPAR up.

I’ve manually modified the /etc/security/user.roles file, adding a role to one of my AD users (who is not defined locally) and then runned setkst. It worked fine, but now I found that there is an issue with pconsole (IBM Systems Director Console). It keeps spawning processes until it fills up the memory, the only solution I’ve found so far is to disable the pconsole services. A ps -ef looks like this, any ideas on what to do or where to look? I’ve already tried manually editing the /etc/security/user.roles file and running setkst again, but it doesn’t fix the problem :confused:.

AIX VIOS IVM Ethernet problem

Leave a comment

By KevB

File Type: txt
Hi All,

I have a p520 box running 3 LPARs, 1 x VIOS, 1 x AIX 6.1 and 1 x AIX 7.1 and no HMC, all configuration is performed via VIOS/IVM

Until recently the box did not have the AIX7.1 LPAR and everything was fine with the box.

We needed to use AIX 7.1 for a new project, so I created a new LPAR and configured it to share the non-VIOS resouces equally with the AIX6.1 LPAR. Everything seemed to go well and I was able to install AIX 7.1 successfully and start using that via PuTTy and FTP as required.

However, it seems that everytime we need to cold-boot the machine, the AIX7.1 LPAR looses visibility of the network. The VIOS and AIX6.1 LPARs remain fine with full network connectivity.

In my investigations so far I have found the following from the VIOS LPAR:

Code:

$ lsdev
name status description
L2cache0 Available L2 Cache
VMLibrary Defined Logical volume
VMrootvg Defined Volume group
cd0 Available SATA DVD-RAM Drive
en0 Defined Standard Ethernet Network Interface
en1 Stopped Standard Ethernet Network Interface

PowerHA HACMP on VIOS servers

Leave a comment

By filosophizer

Few questions regarding Power HA ( previously known as HACMP) and VIOS POWERVM IVM ( IBM Virtualization I/O Server )

[1] Is it possible to create HACMP cluster between two VIOS servers

Physical Machine_1
VIOS_SERVER_1
LPAR_1
SHARED_DISK_XX

VIOS_SERVER_2
Physical Machine_2
LPAR_2
SHARED_DISK_XX

In this scenario, You will have to assign the shared disk first to the VIOS server and from there it will be assigned to LPAR.

Would HACMP work on this shared disk ?

[2] Can you have DLPAR ( Dynamic LPAR ) capabilities in IVM , that is assign one physical Fiber Adapter card to LPAR directly ? IVM VIOS ( which is you are running VIOS without HMC = Hardware Management Console )

in this scenario, you can give the LPAR , shared disk directly from the Storage ? ( provided feature is supported ?! )

[3] DO I need HMC for NPIV or can it run on IVM only ?

What is NPIV?
N_Port ID Virtualization(NPIV) is a standardized method for virtualizing a physical fibre channel port. An NPIV-capable fibre channel HBA can have multiple N_Ports, each with a unique identity. NPIV coupled with the Virtual I/O Server (VIOS) adapter sharing capabilities allow a physical fibre channel HBA to be shared across multiple guest operating systems. The PowerVM implementation of NPIV enables POWER logical partitions (LPARs) to have virtual fibre channel HBAs, each with a dedicated world wide port name. Each virtual fibre channel HBA has a unique SAN identity similar to that of a dedicated physical HBA.
The minimum requirement for the 8 Gigabit Dual Port Fibre Channel adapter, feature code 5735, to support NPIV is 110304

How to install AIX 5 on 9133-55a?

Leave a comment

By pico

hello everyone 😀
i’m new to AIX and i loved it the moment i saw an AIX admin who came to where i work to install an AIX server for an ERP project, i loved it so much that i bought the old server in my company

my server is 9133-55a
the server has no graphic card, and i cant use HMC

how can i install AIX 5 useing serial port to USB? fresh install want to wipe all data on it
PS: after booking the server it beeps 2 times and on the green LCD i see this message “invalid LPAR par”
