    Mark,
    Kind of a good gesture, can you include the latest information for
    everyone so we all can have it.
    TIA,
    David

    Subject: LSM for beginners
    Hi,
    I have an Alpha running V5.1A that is configured to use LSM. I know very
    little about LSM, but need to add 2 new disks as a mirror into an
    existing ADVFS domain. Ie. I want to extend the existing domain by
    adding the mirror.
    I realise I can extend ADVFS domains using addvol but that requires
    ADVFS-UTILS license which I do not have.I would like to know in simple
    terms how to add the new disks into LSM and the file system. Can anyone
    help with the commands to do this?
    I wish to extend the qad_domain (below). The current LSM config is also
    below. Assume for the exercise that the disks are /dev/disk/dsk4c and
    /dev/disk/dsk5c and they are both 18GB disks.Disks 2 and 3 are currently
    mirrored for use by the qad_domain. Disks 0 and 1 are also mirrored for
    use by root and usr.
    #df -k
    Filesystem 1024-blocks Used Available Capacity Mounted on
    root_domain#root 992064 112582 873224 12% /
    /proc 0 0 0 100% /proc
    usr_domain#usr 14338176 2578563 2661576 50% /usr
    usr_domain#var 14338176 26997 2661576 2% /var

    qad_domain#tst 17779712 4309987 6815832 39% /tst

    Following is output from the volprint command:

    A list of the necessary commands would be fabulous.

    Thanks,
