    Hi All,

    Iam trying to find out if there is a way to find out if a perticular SAN disk is presented/zoned to multiple aix boxes.
    This has to be done from AIX and without knowing which is the other node tried lquerypv etc but no luck.

    Any help much appreciated.

    thanks

    The only way I'm aware of is:
    for all of your AIX hosts,
    __for all your FC disks on particualr AIX box,
    ____run the lscfg -vl hdiskN | grep "Serial Number" command
    ____(where N covers all FC disks)
    and then compare the list of Serial Numbers between all AIX hosts.

    The same Serial Number on diff. AIX hosts means the same LUN which is shared among them.
    Btw, be aware that instead of hdisks you may have also vpaths or hdiskpower devices, etc.
    Above should work for IBM disks, I'm not sure this is true for EMC, Hitachi, HP, ...

    Thanks for your response.

    Actually the problem Iam working on is that we've had few incidents where users have varied on a VG while it was active on another node. We do not use lock as these are HA nodes.

    Finding out a way to prevent this.

    thanks

    Take away your user's root access until they learn not to do this.

    Why would people be varying on VG's outside of HACMP control on HA servers?
