DESCRIPTION
The beadm command is the user interface for managing ZFS Boot Environ‐
ments (BEs). This utility is intended to be used by system administra‐
tors who want to manage multiple Oracle Solaris instances on a single
system. Users identify BEs that are to be managed by using BeFmris. For
more information on BeFmris, see the fmri(7) man page.
Using beadm, you can do the following:
o Create a new BE, based on the active BE.
o Create a new BE, based on an inactive BE.
o Create a snapshot of an existing BE.
o Create a new BE, based on an existing snapshot.
o Activate an existing, inactive BE.
o Mount a BE.
o Unmount a BE.
o Destroy a BE.
o Destroy a snapshot of a BE.
o Rename an existing, inactive BE.
o Set policy attributes on a set of BEs.
o Display information about your snapshots, datasets, and non-
global zone BEs.
SUB-COMMANDS
The beadm command has the subcommands and options listed below. Usage
of many of these subcommands and options is illustrated in EXAMPLES,
below.
beadm (no arguments)
Displays command usage.
beadm create [-a] [-d description] [-e non-activeBeFmri | BeFmri@snap‐
shot] [-o property=value] ... BeFmri
Creates a new boot environment named BeFmri. If the -e option is
not provided, the new boot environment will be created as a clone
of the currently running boot environment. If the -d option is pro‐
vided, then the description is also used as the title for the BE's
entry in the GRUB menu for x86 systems or in the boot menu for
SPARC systems. If the -d option is not provided, beName will be
used as the title. Also, non-bootable BEs and snapshots of non-
bootable BEs cannot be specified by using the -e option.
-a
Activate the newly created BE upon creation. The default is to
not activate the newly created BE.
-d description
Create a new BE with a description associated with it.
-e non-activeBeFmri
Create a new BE from an existing inactive BE that resides in
the same zpool as the new BE. Copying BE across zpools is not
allowed. In a zone BE, only bootable BEs can be used with this
option.
-e beFmri@snapshot
Create a new BE from an existing snapshot of the BE named
beFmri. In a zone BE, only snapshots of bootable BEs can be
used with this option.
-o property=value
Create the datasets for a new BE with specific ZFS properties.
Multiple -o options can be specified. See zfs(8) for more
information on the -o option.
beadm create BeFmri@snapshot
Creates a snapshot of the existing BE named BeFmri. Inside a zone
BE, only bootable BEs can be snapshotted.
beadm destroy [-fF] {BeFmri | BeFmriPattern} ... | BeFmri@snapshot ...
Destroys one or more existing boot environments or snapshots of
existing boot environments that match the provided BeFmri or BeFm‐
riPattern.
The BeFmriPattern allows users to include the ? and * characters as
glob(3C)-style wildcards in the BE name or zbe-name field of the
BeFmri to match one or more BEs. The ? and * characters are not
allowed in the zpool field and the zonename field of the BeFmri.
Destroying a boot environment will also destroy all snapshots of
that boot environment. Use this command with caution.
When executing from the global zone and the specified BeFmri or
BeFmriPattern refers to a non-global zone BE, only non-global zone
BEs that are not marked as active on reboot can be destroyed.
When executing inside of a zone BE, only BEs that are bootable or
BEs that are not bootable but are not marked as active on reboot
can be destroyed.
-f
Forcefully unmounts the boot environment if it is currently
mounted.
-F
Force the action without prompting to verify the destruction of
the boot environment.
-O
Destroy all orphaned boot environments. This option can only be
used from inside the Solaris branded zone.
beadm list [[[-a | -ds] [-Z]] | [-o attr[,attr]...]...] [-H]
[{BeFmri| BeFmriPattern}...]
Lists information about existing boot environments that match the
specified BeFmri or BeFmriPattern. If a BeFmri or BeFmriPattern is
not provided, only information for all boot environments in the
zpool of the currently running BE are listed. To display BEs in
zpools not containing the currently running BE, specify the BeFmri‐
Pattern be://<zpool_name>/*.
The Flags field indicates whether the boot environment is active
now, represented by N; active on reboot, represented by R; or both,
represented by NR. Unbootable global zone BEs are represented by an
exclamation point (!). In such BEs the ZFS pool version that they
support is lower than the pool version of the boot pool. Unbootable
BEs inside of a zone BE are represented by an exclamation point
(!). In such zones, the ! flag means that boot environment's boot
artifacts are not resident on the boot pool and, therefore, that BE
is NOT directly bootable. (To transfer a BE's boot artifacts to the
boot pool, either make the BE activate with the activate subcom‐
mand, or change the BE's policy to noevict with the set-policy sub‐
command). Zone boot environments that have no corresponding global
zone boot environment are represented by an O, indicating they are
orphaned.
-a
Lists all available information about the boot environment.
This includes subordinate file systems and snapshots.
-d
Lists information about all subordinate file systems belonging
to the boot environment.
-s
Lists information about the snapshots of the boot environment.
-Z
Lists all zone BEs associated with the global zone BE. This
option is valid only while running in the global zone.
-o attr
Displays the specified attributes, sorted according to the val‐
ues of the first attribute listed. The -o option can be speci‐
fied multiple times, or multiple attributes can be specified as
the argument to one -o option by separating the attribute names
with commas.
The -o option can be specified alone for displaying attributes
in a tabular format. It can also be specified together with the
-H option for semicolon-delimited parsable output.
If an attribute has multiple values and the -H option is not
specified, each value will be displayed in a separate row under
its own column heading. If a multi-value attribute is specified
together with attributes that have a single value, data of the
single-value attribute will only be displayed once under it's
own column heading.
If an attribute has multiple values, and both the -o and -H
option are specified, multiple values are combined into a sin‐
gle string with colon as the delimiter.
The attributes specified must be one of the attributes below.
Attribute names are case-insensitive.
created BE's creation timestamp.
datasets Lists all subordinate filesystems belonging to
the boot environment. This attribute can con‐
tain multiple values.
flags Displays the same information as the Flags
field described above.
fmri FMRI of the BE.
mountpoint Mountpoint for the BE, if mounted. If the BE is
not mounted, this will be blank.
name Name of the BE.
ngz_bes FMRIs of all non-global zone BEs associated
with the global zone BE. This field is only
applicable for global zone BEs. It will be
blank for non-global zone BEs. This attribute
can contain multiple values.
parent_fmri FMRI of a non-global zone BE's parent BE. This
field is only applicable for non-global zone
BEs. It will be blank for global zone BEs.
parent_uuid UUID of a non-global zone BE's parent BE. This
field is only applicable for non-global zone
BEs. It will be blank for global zone BEs.
policy BE's policy.
pool_version The maximum pool version supported by this BE
if known. If unknown, a '-' is displayed. The
pool_version property is cleared when a BE is
mounted read-write and updated when a BE is
unmounted so it is unknown when any non active
BE is mounted read-write.
root_dataset ZFS filesystem name of the root dataset for the
BE.
snapshots Lists all ZFS snapshots belonging to the boot
environment. This attribute can contain multi‐
ple values.
space Total size of the BE.
uuid UUID for the BE. This field will be blank for
non-global zone BEs.
zpool Name of the zpool the BE resides on.
-H
Request machine parsable output. The output format is a list of
lines with semicolon-delimited fields. The space field is dis‐
played in bytes and the created field is displayed in UTC for‐
mat.
If no option is specified, one line with the following fields
is displayed for each boot environment. When running in the
global zone, the uuid field is the uuid of the BE, if applica‐
ble. This field will be blank if it does not have a value. When
running in a non-global zone BE, the uuid field represents the
associated parent BE's uuid.
be-name;uuid;flags;mountpoint;space;policy;created
If the -a, -d, or -s option is specified, one or more of the
following lines are displayed for each boot environment.
fs_name is either a ZFS filesystem name or a ZFS snapshot name,
depending on whether the -d or the -s option is specified.
be-name;fs_name;flags;mountpoint;space;policy;created
If the -Z option is specified, one or more lines with the fol‐
lowing fields are displayed for each non-global zone BE. be-
name is name of the global zone BE associated with the non-
global zone BE. All other fields are attributes of the non-
global zone BE.
be-name;ngz-be-fmri;flags;mountpoint;space;created
If the -o option is specified, values for specified attributes
are displayed as lines with semicolon-delimited fields.
beadm list -z zonename [-z zonename]... [[-a | -ds] | [-o
attr[,attr]...]...] [-H]
Lists information about all zone BEs in the given zones. This com‐
mand is only valid when executing from the global zone. The speci‐
fied zonename must be defined in the currently running global boot
environment.
-a
Lists all available information about each zone boot environ‐
ment. This includes subordinate file systems and snapshots.
-d
Lists information about all subordinate file systems belonging
to each zone boot environment.
-s
Lists information about the snapshots of each zone boot envi‐
ronment.
-o attr
Lists information about the specified attributes of each zone
boot environment, sorted according to the values of the first
attribute listed. The -o option can be specified multiple
times, or multiple attributes can be specified as the argument
to one -o option by separating the attribute names with commas.
See above for the list of valid attribute names.
-H
Does not list header information. Each field in the list infor‐
mation is separated by a semicolon.
If no option is specified, one line with following fields are
displayed for each zone boot environment:
zbe_fmri;parent_fmri;flags;mountpoint;space;created
If the -a, -d, or -s option is specified, one or more of the
following lines are displayed for each zone boot environment:
zbe_fmri;parent_fmri;fs_name;flags;mountpoint;space;created
If the -o option is specified, the specified attributes are
displayed as lines with semicolon-delimited fields.
-z zonename
Lists all zone BEs in the given zone. To list zone BEs in more
than one zone, specify multiple -z options.
beadm mount [-b] BeFmri mountpoint
Mounts a boot environment named BeFmri at mountpoint. mountpoint
must be an already existing empty directory.
If the -b argument is included on the command-line and if there is
an active boot pool dataset associated with the specified BE, that
boot pool dataset will be mounted under <mountpoint>/bootpool_data.
This directory will be automatically created when the dataset is
mounted, and automatically removed when the BE is unmounted with
the beadm
unmount subcommand. Note that unmounting the
BE through another mechanism will NOT clean up this created direc‐
tory.
beadm unmount [-f] BeFmri
Unmounts a boot environment named BeFmri.
-f
Forcefully unmount the boot environment even if it is currently
busy.
beadm rename BeFmri newBeFmri
Renames the boot environment named BeFmri to newBeFmri. In a zone
BE, only bootable BEs can be renamed.
beadm set-policy {-n [-]policy [-n [-]policy2] ...} BeFmri [BeFmri2 .
Sets (or unsets) the specified set of policies for the specified
list of boot environments. Multiple -n arguments are permitted. The
policy string specified with -n may begin with a hyphen. If the
policy begins with a hyphen, that policy is removed from the speci‐
fied list of boot environments. The current set of supported poli‐
cies are:
static The associated boot environment in the root pool is man‐
aged manually and the companion bootable dataset in the
boot pool (if an active boot pool exist) is managed by
the system).
auto The associated boot environment was created by the sys‐
tem automatic update service svc:/system/auto-
update:default and is subject to automatic removal by
the svc:/system/auto-update:cleanup instance based on
the config/keep property.
To opt an auto-update boot evnironment out of automatic
removal and allow it to be preserved and managed manu‐
ally set the policy to static.
The auto policy cannot be set with beadm, it is only set
when the boot environment is created by the auto update
service.
noevict Same as the static policy for the boot environment's
root pool dataset, but the companion bootable dataset in
the boot pool (if an active boot pool exists) is created
(if it does not already exist) and is never removed,
even if the lack of available boot pool space prevents
another boot environment's companion bootable dataset
from being transferred to the boot pool. NOTE that the
boot pool will not be allowed to exceed 85% of its maxi‐
mum capacity to ensure maximum system performance.
beadm activate BeFmri
Makes BE specified by BeFmri as the active BE on next reboot. In a
zone BE, only bootable BEs can be activated.
Zone BE Support
beadm supports the concept of a zone BE, specifically, as it pertains
to BEs for non-global zones. beadm can manage zone BEs from the global
zone BEs or from inside of a non-global zone.
From the global zone, all beadm commands and options can be used for
managing zone BEs. Zone BEs must be specified from the global zone with
a BE FMRI specifying both the zonename and the zone BE name.
beadm functions inside of a non-global zone much the same as it does
from the global zone, with a few exceptions. There is a distinction
made for any given zone BE (or snapshot of a BE) to determine if it is
bootable or not bootable. A zone BE is bootable if it is associated
(that is, shares the same parent id as the active global zone BE's
UUID) with the currently active global zone BE. It is unbootable and
marked with an '!' in the active column in beadm list) otherwise. Note
that, while the non-global zone administrator could mark such a BE as
active by means of beadm activate, rebooting the non-global zone would
not result in the BE being loaded, because the BE is associated with a
non-active global zone BE. A zone BE is considered orphaned if it is
associated with a global zone boot environment that does not exist in
this system, likely due to zone migration. Based on these conditions,
beadm restricts some actions on unbootable BEs thusly:
o You cannot destroy a zone BE that is both unbootable and
marked as active on reboot, unless the unbootable zone BE is
also orphaned.
o You cannot activate an unbootable BE.
o You cannot snapshot an unbootable BE.
o You cannot use an unbootable BE or BE snapshot with the -e
option to beadm create.
o You cannot rename an unbootable BE.

Example 21 Setting policy flags for a set of boot environments
The following command sets the noevict attribute for BEs named BE1,
BE2, and BE3 (and transfers boot artifacts from BE1, BE2, and BE3 to
the boot pool):
# beadm set-policy -n noevict BE1 BE2 BE3
# beadm list
BE Flags Mountpoint Space Policy Created
-- ----- ---------- ----- ------ -------
BE1 - - 6.13M noevict,static 2014-10-20 09:14
BE2 NR / 52.86M noevict,static 2014-10-21 04:33
BE3 - - 559.0K noevict,static 2014-10-22 01:59
BE4 !- - 313.1M static 2014-10-22 04:19
The following command clears the noevict attribute (by setting the list
of attributes to a value that does not include it):
# beadm set-policy -n -noevict BE2
# beadm list
BE Flags Mountpoint Space Policy Created
-- ----- ---------- ----- ------ -------
BE1 - - 6.13M noevict,static 2014-10-20 09:14

Example 22 Listing Specified Attributes of all BEs
The following command lists the BE name, creation date, and root
dataset attributes of all BEs.
# beadm list -o name,created,root_dataset
BE Name Created Root Dataset
-------------- ---------------- --------------
BE1 2015-10-16 10:45 rpool/ROOT/BE1
BE2 2015-10-19 07:04 rpool/ROOT/BE2
BE3 2015-10-20 05:59 rpool/ROOT/BE3
solaris 2015-10-16 08:34 rpool/ROOT/solaris
Example 23 Listing Specified Attributes for a few BEs
The following command lists the BE name, subordinate filesystems, and
creation date for all BEs that match the BeFmriPattern.
# beadm list -o name,datasets,created be://rpool/BE*
BE Name Datasets Created
-------------- ---------------- --------------
BE1 rpool/ROOT/BE1 2015-10-16 10:45
rpool/ROOT/BE1/var
rpool/ROOT/BE1/my_fs
BE2 rpool/ROOT/BE2 2015-10-19 07:04
rpool/ROOT/BE2/var
BE3 rpool/ROOT/BE3 2015-10-20 05:59
rpool/ROOT/BE3/var
Example 24 Listing Specified Attributes
The following command lists the BE name, flags, mountpoint, policy and
creation date for all BEs. These are attributes included in the default
beadm list output. The Space attribute usually included is not speci‐
fied here. Explicitly not including the Space attribute might be useful
on system with a large number of zones, because computing the size for
each BE on such systems takes longer, which results in the beadm list
command being slower.
# beadm list -o name,flags,mountpoint,policy,created
BE Name Flags Mountpoint Policy Created

FILES
<log_dir>/beadm/beadm.yyyymmdd_hhmmss.<pid>.log
Log used for capturing beadm debugging output. A log file is cre‐
ated in one of the following 3 locations for each command invoca‐
tion.
1. /var/share/beadm: This is the preferred location if it
is available and the user has write permission to this
directory.
2. /system/volatile/beadm: This directory is used if the
/var/share dataset is not mounted yet.
3. /tmp/beadm: This directory is used if the user does not
have permission to write to the previous 2 directories.
The time designation portion of the file name is explained as fol‐
lows:
o yyyymmdd_hhmmss — for example, 20071130_140558.
o yyyy — year, 2007
o mm — month, 11
o dd — day, 30
o hh — hour, 14
o mm — minute, 05
o ss — second, 58
If the command is successful, the log file is automatically
removed. If the command fails, the error message will include the
full path to the log file. It is the responsibility of the user to
remove the log file.
