lustatus(1M) System Administration Commands lustatus(1M) NAME
lustatus - display status of boot environments SYNOPSIS
/usr/sbin/lustatus [-l error_log] [-o outfile] [BE_name] [-X] DESCRIPTION
The lustatus 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 lustatus command displays the status information of the boot environment (BE) BE_name. If no BE is specified, the status information for all BEs on the system is displayed. The headings in the lustatus information display are described as follows: Boot Environment Name Name of the BE. Is Complete Indicates whether a BE is able to be booted. Any current activity or failure in an lucreate(1M) or luupgrade(1M) operation causes a BE to be incomplete. For example, if there is a copy operation proceeding on or scheduled for a BE, that BE is considered incomplete. Active Now Indicates whether the BE is currently active. The "active" BE is the one currently booted. Active On Reboot Indicates whether the BE becomes active upon next reboot of the system. Can Delete Indicates that no copy, compare, or upgrade operations are being performed on a BE. Also, none of that BE's file systems are currently mounted. With all of these conditions in place, the BE can be deleted. Copy Status Indicates whether the creation or repopulation of a BE is scheduled or active (that is, in progress). A status of ACTIVE, COMPARING (from lucompare(1M)), UPGRADING, or SCHEDULED prevents you performing Live Upgrade copy, rename, or upgrade operations. The following is an example lustatus display: Boot Environment Is Active Active Can Copy Name Complete Now On Reboot Delete Status -------------------- -------- ------ --------- ------ ---------- disk_a_S7 yes yes yes no - disk_b_S7db yes no no no UPGRADING disk_b_S8 no no no no - S9testbed yes no no yes - Note that you could not perform copy, rename, or upgrade operations on disk_b_S8, because it is not complete, nor on disk_b_S7db, because a Live Upgrade operation is pending. The lustatus command requires root privileges. OPTIONS
