    NSSMU utility

    How to use NSSMU utility to do mirroring ? Any step by step instruction ?
    I'm planning to mirror my 2 harddisks but not sure the exact step need to be
    done. Pls advise. Thanks

    Install 2nd HDD

    Boot to DOS using FDISK
    (FDISK /X is using DRDOS)
    FDISK and create a Partition on the 2nd HDD slightly smaller than 1st one
    ie. if C: is 500Mb on the other drive make the new partition 490Mb
    (the Actual space required by Netware boot files is 100Mb)

    After Partitioning Re-Boot
    At C: prompt type FORMAT D: /s
    (or Format D: /s /x if using DRDOS)

    Once formatted use XCOPY to copy C: to D: (required if and when you want to
    boot the 2nd disk from the Mirror pair if 1st one fails)

    Load the Server
    Type NSSMU
    Goto Partition
    Select the 1st Partition (SYS not DOS)
    Press F3 to creat a mirror
    If you have another Partition ie: DATA do the same to DATA

    (NB: 2nd HDD must be same or greater size than 1st one)

    Thats it....

    Escape out of NSSMU

    You can type MIRROR STATUS at the server prompt to get idea of progress

    Different verions behave slightly differently

    ie. NW65Sp4 will FINISH SYS before starting DATA
    previous versions did both at the same time

    (Hey, Practice using a non production server - that way you can't xxxx it
    up!!)

    Re: NSSMU utility

    Thanks Martin, its quite in details. But i just did it in NRM. Is it same as
    NSSMU ? In NRM i actually accidentally created extra 2 mirrors. Does it mean
    i have total 3 drives or partitions for 2nd drive ? Can those be deleted ?

    NRM and NSSMU are equivalent ways of using the same feature -- Netware
    mirroring -- although NSSMU is more capable and flexible.

    You can view the mirror set you created from NRM by going to NSSMU, and
    selecting RAID DEVICES. The first screen will give you a summary of what
    you have -- should just be 1 entry. Pressing ENTER will show the segments
    of the mirror; you can add or delete segments from that view.

    You can also get a quick status from the console by typing "mirror
    status". You should get a summary back that references a mirror object
    (for instance, on my console, I see "Mirrored object 0x12 is
    synchronized"); using that number in the mirror status command shows the
    segment status (for example, "mirror status 12").

    And more 'familiar' to those of us used to doing this from Install or
    NWCONFIG in the past...

    Re: NSSMU utility

    What do you mean by just 1 ? mirror set ? each segment represents 1 volume ?

    When you clicked the "mirror this" link in NRM, you created a mirror set.
    From your description, I believe only 1 mirror set was created. NSSMU
    will show you all mirror sets, whether I'm right about the number 1 or not.

    A mirror set is a virtual partition that is made up of all the physical
    partitions on the (different) drives. Each segment is 1 or more physical
    partitions, and represents 1 copy of the virtual partition.

    A mirror set is also referred to as a "RAID 0 Device", with -- in this
    case -- Netware providing the RAID 0 (mirroring).

    All this is way below the level of volumes. Only partitions are
    mirrored. Volumes live in pools that live in partitions.

    Now i have 3 mirror set/virtual partitions. So is it fine to remove 2
    virtual partitons that i accidentally created using NSSMU ?

    Please post the results of the console command "mirror status".
