Using Solaris Live Upgrade

March 17, 2008 by sun4u

The lucreate command is part of a suite of commands that make up the Live Upgrade feature of the Solaris Operating environment.

Example:

# lucreate -n newsystem-new -c solaris10 -m /:/dev/dsk/c0t2d0s0:ufs -m -:/dev/dsk/c0t2d0s1:swap \-m /var:/dev/dsk/c0t2d0s5:ufs -m /usr:/dev/dsk/c0t2d0s6:ufs -m /opt:/dev/dsk/c0t2d0s7:ufs \

-l /var/log/lucreate.err -o /var/log/lucreate.log

BE: Boot Environment

-n: The name of the BE to be created. BE must be unique on a given system

-c: The current BE

-m: mount point:device[,volume]:fs

-l: Error messages and other status messages are sent to error log

-o: All command output is sent to outfile

To check the status of the BEs

The lustatus command displays the status information of the boot environment (BE)

#lustatus

Boot Environment Is Active Active Can Copy

Name Complete Now On Reboot Delete Status

solaris10 yes yes yes no -
