ProcedureSPARC: How to Install a Boot Block on a System Disk

  1. Become superuser or assume an equivalent role.

  2. Install a boot block on the system disk.

    For a UFS root file system:


    # installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk
/dev/rdsk/cwtxdys0
    /usr/platform/`uname -i`/lib/fs /ufs/bootblk

    Is the boot block code.

    /dev/rdsk/cwtxdys0

    Is the raw device of the root (/) file system.

    For a ZFS root file system:


    # installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk
/dev/rdsk/cwtxdys0
    /usr/platform/`uname -i`/lib/fs/zfs/bootblk

    Is the boot block code.

    /dev/rdsk/cwtxdys0

    Is the raw device of the root (/) file system.

    For more information, see installboot(1M).

  3. Verify that the boot blocks are installed by rebooting the system to run level 3.
