Solaris Express Installation Guide: Solaris Live Upgrade and Upgrade Planning

ProcedureTo Compare Boot Environments

  1. Become superuser or assume an equivalent role.

    Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

  2. Type:

    # /usr/sbin/lucompare -i  infile (or) -t -o  outfile BE_name
    -i  infile

    Compare files that are listed in infile. The files to be compared should have absolute file names. If the entry in the file is a directory, then comparison is recursive to the directory. Use either this option or -t, not both.


    Compare only nonbinary files. This comparison uses the file(1) command on each file to determine if the file is a text file. Use either this option or -i, not both.

    -o  outfile

    Redirect the output of differences to outfile.


    Specifies the name of the boot environment that is compared to the active boot environment.

Example 7–2 Comparing Boot Environments

In this example, first_disk boot environment (source) is compared to second_disk boot environment and the results are sent to a file.

# /usr/sbin/lucompare -i  /etc/lu/compare/ \
-o /var/tmp/compare.out second_disk
