    Thanks to all who replied.

    Original question was is there a SDS equivalent to the vxassist maxgrow
    and there isn't (reason why I couldn't find it in the manual). Special
    thanks to Adam Tomkinson who gave detailed instructions for growing SDS
    file system/volume:

    Yes, Metattach and growfs are the way to go:

    Extending a metadevice
     ----------------------
    # metattach d1 c3t1d0s2
    extends a metadevice by concatenating a slice to the end. It does not
    add
    a filesystem.

    # growfs /dev/md/rdsk/d1

    If the metadevice is not mounted, the above command extends the
    filesystem
    to include the added section. You cannot shrink this filesystem later.

    # growfs -M /export/home /dev/md/rdsk/d1

    If the metadevice is mounted, the above command will extend the
    filesystem to
    include the concatenated section. Again, you cannot shrink the
    filesystem later.

    All,

    Some clarification, I am looking for an equivalent command to the
    Veritas vol mgr vxassist maxgrow command in SDS so I can see how much
    available space I have to grow the current FS. I googled, looked in
    docs.sun and sunmanagers.org and couldn't find it. In addition, since I
    am not familiar with SDS commands and they seem more cryptic than Vxvm
    (or maybe its what you're used to), I wanted to make sure metattach and
    growfs were the way to go. The documentation isn't that clear.

    Thanks

    Hi all,

    We mainly use Volume Manager but we have a server that has SDS 4.2.1
    soft partitions setup that need their size increased. Can anyone tell me
    how can you tell how much space there is available to each md and also
    the proper commands to actually grow with ie; metattach then growfs?

    File systems look like this:

    /dev/md/dsk/d3 5161518 614843 4495060 13% /u05/oraredo1

    /dev/md/dsk/d9 8261869 1049115 7130136 13% /u07/mviewlogs

    /dev/md/dsk/d4 15490539 4207907 11127727 28% /u02/oradata1

    /dev/md/dsk/d6 20654313 7355963 13091807 36% /u04/oradata3

    /dev/md/dsk/d7 20654313 10503275 9944495 52% /u03/oradata2

    /dev/md/dsk/d8 5161518 411275 4698628 9% /u06/oraredo2

    /dev/md/dsk/d10 30981862 1579162 29092882 6% /u08/orabkup

    /dev/md/dsk/d1 51636959 4455611 46664979 9% /export/home

    /dev/md/dsk/d2 10326764 2403707 7819790 24% /u01/app/oracle

    Thanks
