lumake(1M)                                                System Administration Commands                                                lumake(1M)

NAME
lumake - populate a boot environment SYNOPSIS
/usr/sbin/lumake [-l error_log] [-o outfile] [-s source_BE] -n BE_name [-X] /usr/sbin/lumake [-l error_log] -t time [-o outfile] [-s source_BE] -n BE_name [-m email_address] [-X] DESCRIPTION
The lumake command is part of a suite of commands that make up the Live Upgrade feature of the Solaris operating environment. See live_upgrade(5) for a description of the Live Upgrade feature. The lumake command populates (that is, copies files to) the file systems of a specified boot environment (BE) by copying files from the corresponding file systems of the active or a source (-s) BE. Any existing data on the target BE are destroyed. All file systems on the target BE are re-created. The target BE must already exist. Use lucreate(1M) to create a new BE. The lumake command requires root privileges. OPTIONS
The lumake command has the following options: -n BE_name Name of the BE to be populated. -s source_BE The optional name of a source BE. If you omit this option, lumake uses the current BE as the source. A BE must have the status "complete" before you can copy from it. Use lustatus(1M) to determine a BE's status. -l error_log Error and status messages are sent to error_log, in addition to where they are sent in your current environment. -o outfile All command output is sent to outfile, in addition to where it is sent in your current environment. -t time Setup a batch job to populate the specified BE at a specified time. The time is given in the format specified by the at(1) man page. At any time, you can have only one Live Upgrade operation scheduled. You can use lucancel(1M) to cancel a scheduled lumake operation. -m email_address Allows you to email lumake output to a specified address upon command completion. There is no checking of email_address. You can use this option only in conjunction with -t. -X Enable XML output. Characteristics of XML are defined in DTD, in /usr/share/lib/xml/dtd/lu_cli.dtd.<num>, where <num> is the version number of the DTD file. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. FILES
/etc/lutab list of BEs on the system /usr/share/lib/xml/dtd/lu_cli.dtd.<num> Live Upgrade DTD (see -X option) ATTRIBUTES
