Comparing Boot Environments

Use the lucompare command to check for differences between the active boot environment and other boot environments. To make a comparison, the inactive boot environment must be in a complete state and cannot have a copy job that is pending. See Displaying the Status of All Boot Environments.

The lucompare command generates a comparison of boot environments that includes the contents of any non-global zones.

The specified boot environment cannot have any partitions that are mounted with lumount or mount.

To 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.

   -t

   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.

   BE_name

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

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
