How to Manage Volumes With Solaris Live Upgrade

When creating a boot environment, you can use Solaris Live Upgrade to manage the following tasks.

• Detach a single-slice concatenation (submirror) from a RAID-1 volume (mirror). The contents can be preserved to become the content of the new boot environment if necessary. Because the contents are not copied, the new boot environment can be quickly created. After the submirror is detached from the original mirror, the submirror is no longer part of the mirror. Reads and writes on the submirror are no longer performed through the mirror.

• Create a boot environment that contains a mirror.

• Attach a maximum of three single-slice concatenations to the newly created mirror.

You use the lucreate command with the -m option to create a mirror, detach submirrors, and attach submirrors for the new boot environment.

If VxVM volumes are configured on your current system, the lucreate command can create a new boot environment. When the data is copied to the new boot environment, the Veritas file system configuration is lost and a UFS file system is created on the new boot environment.
