    This article was published in the April 2006 issue of AIX Update magazine and discusses how to implement AIX in an environment dedicated to business continuity. The topic of this article is the assignment of MQ Series queue names and aliases, resource group startup and shutdown script names (Application startup/shutdown script names), error logging, and error notification.

  • Successful Business Continuity - Part 5 - Miscellaneous topics
    This article was published in the August 2006 issue of AIX Update magazine and discusses how to implement AIX in an environment dedicated to business continuity. A variety of topics is discussed in this article including automated documentation generation and management.

  • Automated Microcode Management System
    One of the most difficult administration tasks in an AIX environment is attempting to keep the firmware and microcode up-to-date. Mt Xia has devised an automated method of gathering the Microcode information, determining which microcode needs to be updated, generating reports, and uploading the required microcode updates to each individual system.

  • Calculating the size of a Virtual Processor
    This document describes the algorithms used to calculate the size of a virtual processor when using shared processors in an LPAR. The IBM documentation describes how to calculate CPU utilization, NOT how to size for configuration, this document clarifies this process. A description of the HMC input fields for the processor tab is included.

    • This document describes a standard for establishing virtual ethernet adapters in the VIO Server environment. This standard is specific to the numbering scheme used to identify the VLAN ID's of the virtual ethernet adapters. The VLAN ID number is also referred to in the HMC as the PVID number.

    This document assumes there are two VIO servers in the environment and the names of the VIO servers are represented by "*vio0" and "*vio5".

    The VLAN ID numbers will be three digit numbers, each digit representing a different aspect of the underlying ethernet adapter.

    3 Digit VLAN ID Number
    First Digit Second Digit Third Digit
    5: Boot/Service
    6: Standby
    7: Backup
    8: Management
    9: Intra-Frame     		0: Gigabit
    5: 10/100
    9: Bus     		0,2,4,6,8: VIO Server with even numbered hostnames
    1,3,5,7,9: VIO Server with odd numberd hostnames

    The first digit of the VLAN ID numbers associated with virtual ethernet adapters will be used to represent a variety of adapter purposes. Those purposes include boot, standby, backup, management, and intra-frame communications.

    • 500-599: boot/service
    • 600-699: standby
    • 700-799: backup
    • 800-899: management
    • 900-999: intra-frame

    The third digit of the three digit VLAN ID number assigned to virtual ethernet adapters associated with the VIO Server named *vio0 will end with a number between 0 and 4.

    Example: 500, 501, 502, 510, 520, 521, ...

    The VLAN ID numbers assigned to virtual ethernet adapters associated with the VIO Server named *vio5 will end with an odd number beginning at 5.

    Example: 505, 506, 507, 515, 525, 526, ...

    The second digit of the three digit VLAN ID sequence will represent the adapter speed, gigabit cards will be represented by 0 thru 4, 10/100 adapters by 5 thru 8, and bus speed adapters by a 9. This digit may be reconfigured as necessary.

    Examples:

    Adapter Speed
    VLAN ID Adapter Type Adapter Speed VIO Server
    500 Boot 0 Gigabit *vio0
    501 Boot 1 Gigabit *vio0
    505 Boot 0 Gigabit *vio5
    506 Boot 1 Gigabit *vio5
           
    550 Boot 0 10/100 *vio0
    551 Boot 1 10/100 *vio0
    555 Boot 0 10/100 *vio5
    556 Boot 1 10/100 *vio5
           
    590 Boot 0 Bus *vio0
    591 Boot 0 Bus *vio0
    595 Boot 0 Bus *vio5
    596 Boot 1 Bus *vio5

    An LPAR may have multiple adapters of a variety of types, for example an LPAR that provides database services and is a member of an HACMP cluster may have boot, standby, management, backup, and intra-frame virtual adapters as follows:

    • Gigabit adapter used for boot/service address
    • Gigabit adapter used for standby address
    • 10/100 backup adapter
    • 10/100 management adapter
    • 2 intra-frame adapters

    VIO Server Configuration:
    VLAN ID Adapter Type Adapter Speed VIO Server
    500 Boot Gigabit *vio0
    600 Standby Gigabit *vio0
    750 Backup 10/100 *vio0
    850 Management 10/100 *vio0
    990 Intra-frame Bus *vio0
    991 Intra-frame Bus *vio0
           
    505 Boot Gigabit *vio5
    605 Standby Gigabit *vio5
    755 Backup 10/100 *vio5
    855 Management 10/100 *vio5
    995 Intra-frame Bus *vio5
    996 Intra-frame Bus *vio5

    LPAR VLAN ID configuration to utilize virtual adapters:
    VLAN ID Adapter Type Adapter Speed VIO Server
    500 Boot Gigabit *vio0
    505 Boot Gigabit *vio5
    600 Standby Gigabit *vio0
    605 Standby Gigabit *vio5
    750 Backup 10/100 *vio0
    755 Backup 10/100 *vio5
    850 Management 10/100 *vio0
    855 Management 10/100 *vio5
    990 Intra-frame Bus *vio0
    991 Intra-frame Bus *vio0
    995 Intra-frame Bus *vio5
    996 Intra-frame Bus *vio5
