It’s worth reading all the headings before beginning the installation process:<\/p>\n

Hardware requirements<\/h3>\n

Min 1GB RAM (recommended amount is 2GB or more)<\/p>\n

To find out the amount of installed RAM<\/p>\n

[crayon]#lsattr -E -l sys0 -a realmem[\/crayon]<\/p>\n

Swap requirements<\/h3>\n

For 1-2 GB Physical RAM, 1.5 the amount of RAM
\nFor 2-16 GB Physical RAM, the swap amount can be the same as the physical RAM
\nFor systems with more than 16GB Physical RAM, 16GB of swap space is sufficient
\nChecking the size of the swap amount:
\n[crayon]#lsps -a[\/crayon]
\nIf the amount of swap space is insufficient, instructions showing how to increase its size are provided at the end of the page.<\/p>\n

How to mirror an AIX rootvg<\/strong><\/p>\n

The following steps will guide you trough the mirroring of an AIX rootvg.<\/p>\n

This info is valid for AIX 4.3.3, AIX 5.1, AIX 5.2 and AIX 5.3.<\/p>\n

Make sure you have an empty disk, in this example its hdisk1<\/strong><\/p>\n

    \n
  1. Add the disk to the vg via “extendvg rootvg hdisk1<\/li>\n
  2. Mirror the vg via: “mirrorvg rootvg”<\/li>\n
  3. Adapt the bootlist to add the current disk, the system will then fall to hdisk1 if hdisk0 fails during startup<\/li>\n
  4. do bootlist -o -m normal , this will list currently 1 disk, in this exaple hdisk0<\/li>\n
  5. do bootlist -m normal hdisk0 hdisk1<\/li>\n
  6. Run a bosboot on both new disks, this will install all software needed for boot on the disk:<\/li>\n<\/ol>\n

    a. bosboot -ad hdisk0<\/p>\n

    b. bosboot -ad hdisk1<\/p>\n

    AIX Best Practices<\/h3>\n

    An explanation of the best practices after installing AIX can be found in the following link. It includes what the applicable practices are, why they are so and how to apply them.<\/p>\n

    http:\/\/www.ibm.com\/developerworks\/wikis\/display\/WikiPtype\/AIXV53AdminBestPractice<\/a><\/p>\n

    – This page contains useful commands: http:\/\/www.ibm.com\/developerworks\/aix\/library\/au-dutta_cmds.html<\/a><\/p>\n

    – With every installation try to get the latest patches, but before applying the patches check online to see if any there have been any problems with them.<\/p>\n

     <\/p>\n

    Hands-On tips<\/h3>\n

    1. <\/strong>Adjusting the Paging Space<\/p>\n

    The suggested size of the paging space hd6 can be determined by the amount of RAM on the system and by using the following table.<\/p>\n

    Please note that these values are only an initial suggestion for the paging space size with the default system settings, you may be required to resize when necessary.<\/p>\n\n\n\n\n\n\n
    RAM (GB)<\/td>\nPaging Space Size<\/td>\n<\/tr>\n
    1 to 32GB<\/td>\n1\/2 of total RAM (512MB to 16GB)<\/td>\n<\/tr>\n
    32 to 64GB<\/td>\n1\/4 of total RAM (8 to 16GB)<\/td>\n<\/tr>\n
    64 to 128GB<\/td>\n1\/8 of total RAM (8 to 16GB)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    2.<\/strong> Increase the size of the Oracle fs. (for example: chfs -a size=+2G \/var)<\/p>\n

    3.<\/strong> Arrange the size of the dump device, the sysdumpdev -K command enables sysdump.<\/p>\n

    4.<\/strong> Install open source programs such as OpenSSL, OpenSSH, BASH, GNU Screen, VNC, LSOF.<\/p>\n

    5.<\/strong> Before changing any file under \/etc, first make a copy using cp -p.<\/p>\n

    6.<\/strong> Remove the default user limits:<\/p>\n

    vi \/etc\/security\/limits<\/p>\n

    fsize=-1<\/p>\n

    7.<\/strong> If rootvg is the local (internal disk) check the bootlist by mirroring (mirrorvg rootvg).<\/p>\n

    8.<\/strong> Arrange the SCSI and hdisk attributes.<\/p>\n

    a)<\/strong> Through vio, do the following in Lpar:<\/p>\n

    chdev -a hcheck_interval=60 -a hcheck_mode=nonactive -l hdisk0 -P (requires a restart)<\/p>\n

    chdev -a hcheck_interval=60 -a hcheck_mode=nonactive -l hdisk1;<\/p>\n

    chdev -l vscsi0 -a vscsi_path_to=30 -a vscsi_err_recov=fast_fail -P (requires a restart)<\/p>\n

    chdev -l vscsi1 -a vscsi_path_to=30 -a vscsi_err_recov=fast_fail -P (requires a restart)<\/p>\n

    chpath -l hdisk0 -p vscsi1 -a priority=2 (hdisk0, should go from vscsi0)<\/p>\n

    chpath -l hdisk1 -p vscsi0 -a priority=2 (hdisk1, goes from hdisk1)<\/p>\n

    b)<\/strong> Physical SCSI (Fiber Channel)<\/p>\n

    chdev -l fscsi0 -a fc_err_recov=fast_fail -a dyntrk=yes -P<\/p>\n

    chdev -l fscsi1 -a fc_err_recov=fast_fail -a dyntrk=yes -P<\/p>\n

    9.<\/strong> Adjust the TimeZone, enable daylisgt saving, restart and set the datetime.<\/p>\n

    10.<\/strong> If a dns is present, set the ntp<\/p>\n

    11.<\/strong> Add a PS1 to \/etc\/profile<\/p>\n

    vi \/etc\/profile;<\/p>\n

    PS1=”$LOGNAME@$(hostname):\\$PWD> ”<\/p>\n

    set -o vi<\/p>\n
