Welcome to the PowerAdm wiki!

Power Adm is a free (BSD License) and simple tool in Python to create easily, quickly and with their standards LPARs and in the future could make deploy AIX Operating System.

Principal features

• Create LPAR profile on HMC
• Supports multiple frames
• Add virtual Ethernet (maximum 3 ethernets)
  • Select the Virtual Switch
  • VLAN
• Add vSCSI on two VIOs
  • Create Virtual SCSI server on VIO automatically
• Add NPIV on two VIOs
  • Make vfcmap automatically
• Add disk on vSCSI (only if you have Shared Storage Pool)
• Centralized config (poweradm/config.py)
• Organize your IDs!!! You don't Know are this? Continue reading...

In the future:

• Deploy SO from the NIM Server
• Web Interface

Who manages environment with IBM Power through the Hardware Management Console (HMC) know that we have easy management interface to create LPAR, but we need to manage the IDs of devices, such as virtual network, virtual fiber channel, virtual scsi etc., and manage information the maximum and minimum memory and CPUs, physical devices, capped, uncapped etc.

The objective of this tool is to adopt a standard IDs based on LPAR ID and facilitate the creation without a complex information. Is easy for analysts without skills in Power or operators.

Power Adm is a free and simple tool in Python to create easily, quickly and with their standards LPARs.

Something that really consider the differential is the organization IDs.

IDs Structure / Organize your IDs

These IDs are well organized, assist in the identification of devices, particularly in times of troubleshooting in environments with a large number of LPARs These IDs also help in managing the Live Partition Mobility, that is, if well organized will remain independent of the box.

For this, the following rule was established:

All LPAR has a maximum number of virtual devices 40 and the following structure: Virtual Network IDs will be between 10 and 19 Virtual SCSI IDs will be between 20 and 29 (default 21 primary VIO, 22 secondary VIO) Virtual Fibre Channel IDs will be between 30 and 39 (default 33 primary VIO, 34 secondary VIO)

In "VIOS" settings have the following default: Maximum number of virtual devices in VIO Primary is 3500 and Secondary VIO 4500 allowing a total of 500 LPARs on the set of VIOS

Virtual SCSI IDs: the VIO Primary 1 + 'LPAR ID' and on VIO Secondary 2 + 'LPAR ID' Fiber Channel IDs: the VIO Primary 3 + 'LPAR ID' and on VIO Secondary 4 + 'LPAR ID'

Example:

VIOS1 - ID: 1 Maximum number of virtual IDs: 3500 VIOS2 - ID: 2 Maximum number of virtual IDs: 4500

LPAR AIX1 ID: 11 Virtual devices:

• 11: Network adapter data
• 12: Network adapter backup
• 21: Virtual SCSI (Server: 111 VIOS1)
• 22: Virtual SCSI (Server: 211 VIOS2)
• 33: Fiber Channel (Server: 311 VIOS1)
• 34: Fiber Channel (Server: 411 VIOS2)

LPAR AIX1 ID: 12 Virtual devices:

• 11: Network adapter data
• 12: Network adapter backup
• 21: Virtual SCSI (Server: 112 VIOS1)
• 22: Virtual SCSI (Server: 212 VIOS2)
• 33: Fiber Channel (Server: 312 VIOS1)
• 34: Fiber Channel (Server: 412 VIOS2)

VIOS1 ID: 1 Virtual devices:

• 111 Virtual SCSI (Client ID: 11 / Virtual Client: 21)
• 112 Virtual SCSI (Client ID: 12 / Virtual Client: 21)
• 311 Fiber Channel (Client ID: 11 / Virtual Client: 33)
• 312 Fiber Channel (Client ID: 12 / Virtual Client: 33)

VIOS2 ID: 2 Virtual devices:

• 211 Virtual SCSI (Client: 11 / Virtual Client: 22)
• 212 Virtual SCSI (Client: 12 / Virtual Client: 22)
• 411 Fiber Channel (Client: 11 / Virtual Client: 34)
• 412 Fiber Channel (Client: 12 / Virtual Client: 34)

With this example we can see how easy it is to identify within the VIO's virtual devices, searching for the partition ID.

Sample: Identifying AIX1 on VIOs

padmin@VIOS1:[/home/padmin]lsmap -all | grep C111

How is it development?

It's developing using Python and uses some Shell Scripting. I'm not a developer. I'm a System Administrator. Please sorry if not look great but your help is important to improve.

If you don't have an HMC and a Power to run tests, don't worry. I've an some codes with simulation on createlparconf.py, newid.py. D irectory simulation is available upon request.
