    Hi friends,

    I have AIX 5.3 servers in my environment which is connected with Netapps storage. (FAS6080-R5). We dont have multipathing software installed on our servers. I am a HP-UX guy I know how to configure in HPUX but dont have knowledge on AIX. Last week I have added disks on AIX server, but havnt done anything with multipathing, any help will be appreciable. Need help on configuring multipathing on AIX.

    Thanks
    Madan

    As long as the NetApp FCP AIX Host Utilities are installed, then multipathing is handled by the AIX Default Path Control Module (PCM). So, all you should need to do is run cfgmgr once the disk has been presented to the AIX hosts.

    You can use the AIX command, lspath and the NetApp tool, sanlun to check that multipathing is working as expected. e.g.

    1. lspath -l hdisk0
    Enabled hdisk0 fscsi0
    Enabled hdisk0 fscsi0
    Enabled hdisk0 fscsi2
    Enabled hdisk0 fscsi2
