    Managers,

    the / and swap file systems on my server are disksuite
    metadevices like this

    /dev/md/dsk/d0 ------> /
    /dev/md/dsk/d1 ------> swap

    both d0 and d1 are set up as mirrors:

    d0 ---- d10 (c0t0d0s0)
       \
        \ d20 (c0t1d0s0)

    d1 ----- d11 (c0t0d0s1)
       \
        \ d21 (c0t1d0s1)

    I am currently testing to boot from the submirrors and
    physical slices. For example,

    if I metadetach the second submirror and reboot the
    machine, it works fine. If I "metaroot c0t0d0s0" and
    reboot, the machine works fine too.

    However, when I do "metaroot c0t1d0s0", or "ok> boot
    mirror" (mirror is aliased to the slice on the second
    drive), it fails to boot with this error:

    Executing last command: boot mirror
    Boot device: /pci@1f,0/pci@1,1/scsi@2/disk@1,0 File
    and args:

    INIT: Cannot create /var/adm/utmpx

    INIT: failed write of utmpx entry:" "

    INIT: failed write of utmpx entry:" "

    INIT: SINGLE USER MODE

    Type control-d to proceed with normal startup,
    (or give root password for system maintenance):

    I have already install the boot block onto the seond
    drive.

    Any solutions?

    Thanks
