Commands Used on a Solaris System With Zones Installed

The commands identified in Table 26-3 provide the primary administrative interface to the zones facility.

Table 26-3 Commands Used to Administer Zones

Command Reference

Description

zlogin(1)

Log in to a non-global zone

zonename(1)

Prints the name of the current zone

zoneadm(1M)

Administers zones on a system

zonecfg(1M)

Used to set up a zone configuration

getzoneid(3C)

Used to map between zone ID and name

zones(5)

Provides description of zones facility

zcons(7D)

Zone console device driver

The zoneadmd daemon is the primary process for managing the zone's virtual platform. The man page for the zoneadmd daemon is zoneadmd(1M). The daemon does not constitute a programming interface.

The commands in the next table are used with the resource capping daemon.

Table 26-4 Commands Used With rcapd

Command Reference

Description

rcapstat(1)

Monitors the resource utilization of capped projects.

rcapadm(1M)

Configures the resource capping daemon, displays the current status of the resource capping daemon if it has been configured, and enables or disables resource capping

rcapd(1M)

The resource capping daemon.

The commands identified in the following table have been modified for use on a Solaris system with zones installed. These commands have options that are specific to zones or present information differently. The commands are listed by man page section.

Table 26-5 Commands Modified for Use on a Solaris System With Zones Installed

Command Reference

Description

ipcrm(1)

Added -z zone option. This option is only useful when the command is executed in the global zone.

ipcs(1)

Added -z zone option. This option is only useful when the command is executed in the global zone.

pgrep(1)

Added -z zoneidlist option. This option is only useful when the command is executed in the global zone.

ppriv(1)

Added the expression zone for use with the -l option to list all privileges available in the current zone. Also use the option -v after zone to obtain verbose output.

priocntl(1)

Zone ID can be used in idlist and -i idtype to specify processes. You can use the priocntl -i zoneid command to move running processes into a different scheduling class in a non-global zone.

proc(1)

Added -z zone option to ptree only. This option is only useful when the command is executed in the global zone.

ps(1)

Added zonename and zoneid to list of recognized format names used with the -o option.

Added -z zonelist to list only processes in the specified zones. Zones can be specified either by zone name or by zone ID. This option is only useful when the command is executed in the global zone.

Added -Z to print the name of the zone associated with the process. The name is printed under an additional column header, ZONE.

renice(1)

Added zoneid to list of valid arguments used with the -i option.

sar(1)

If executed in a non-global zone in which the pools facility is enabled, the -b, -c -g, -m, -p, -u, -w, and -y options display values only for processors that are in the processor set of the pool to which the zone is bound.

auditconfig(1M)

Added zonename token.

auditreduce(1M)

Added -z zone-name option. Added ability to get an audit log of a zone.

coreadm(1M)

Added variable %z to identify the zone in which process executed.

df(1M)

Added -Z option to display mounts in all visible zones. This option has no effect in a non-global zone.

ifconfig(1M)

Added zone option for global zone use (the default), and -zone zonename for non-global zone use.

iostat(1M)

If executed in a non-global zone in which the pools facility is enabled, information is provided only for those processors that are in the processor set of the pool to which the zone is bound.

kstat(1M)

If executed in the global zone, kstats are displayed for all zones. If executed in a non-global zone, only kstats with a matching zoneid are displayed.

mpstat(1M)

If executed in a non-global zone in which the pools facility is enabled, command only displays lines for the processors that are in the processor set of the pool to which the zone is bound.

ndd(1M)

When used in the global zone, displays information for all zones. ndd on the TCP/IP modules in an exclusive-IP zone only displays information for that zone.

netstat(1M)

Displays information for the current zone only.

nfsstat(1M)

Displays statistics for the current zone only.

poolbind(1M)

Added zoneid list. Also see Resource Pools Used in Zones for information about using zones with resource pools.

prstat(1M)

Added -z zoneidlist option. Also added -Z option.

If executed in a non-global zone in which the pools facility is enabled, the percentage of recent CPU time used by the process is displayed only for the processors in the processor set of the pool to which the zone is bound.

Output of the -a, -t, -T, -J, and -Z options displays a SWAP instead of a SIZE column. The swap reported is the total swap consumed by the zone's processes and tmpfs mounts. This value assists in monitoring the swap reserved by each zone, which can be used to choose a reasonable zone.max-swap setting.

psrinfo(1M)

If executed in a non-global zone, only information about the processors visible to the zone is displayed.

traceroute(1M)

Usage change. When specified from within a non-global zone, the -F option has no effect because the “don't fragment” bit is always set.

vmstat(1M)

When executed in a non-global zone in which the pools facility is enabled, statistics are reported only for the processors in the processor set of the pool to which the zone is bound. Applies to output from the -p option and the page, faults, and cpu report fields.

auditon(2)

Added AUDIT_ZONENAME to generate a zone ID token with each audit record.

priocntl(2)

Added P_ZONEID id argument.

processor_info(2)

If the caller is in a non-global zone and the pools facility is enabled, but the processor is not in the processor set of the pool to which the zone is bound, an error is returned.

p_online(2)

If the caller is in a non-global zone and the pools facility is enabled, but the processor is not in the processor set of the pool to which the zone is bound, an error is returned.

pset_bind(2)

Added P_ZONEID as idtype. Added zone to possible choices for P_MYID specification. Added P_ZONEID to valid idtype list in EINVAL error description.

pset_info(2)

If the caller is in a non-global zone and the pools facility is enabled, but the processor is not in the processor set of the pool to which the zone is bound, an error is returned.

pset_list(2)

If the caller is in a non-global zone and the pools facility is enabled, but the processor is not in the processor set of the pool to which the zone is bound, an error is returned.

pset_setattr(2)

If the caller is in a non-global zone and the pools facility is enabled, but the processor is not in the processor set of the pool to which the zone is bound, an error is returned.

sysinfo(2)

Changed PRIV_SYS_CONFIG to PRIV_SYS_ADMIN.

umount(2)

ENOENT is returned if file pointed to by file is not an absolute path.

getloadavg(3C)

If the caller is in a non-global zone and the pools facility is enabled, the behavior is equivalent to calling with a psetid of PS_MYID.

getpriority(3C)

Added zone IDs to target processes that can be specified. Added zone ID to EINVAL error description.

priv_str_to_set(3C)

Added “zone” string for the set of all privileges available within the caller's zone.

pset_getloadavg(3C)

If the caller is in a non-global zone and the pools facility is enabled, but the processor is not in the processor set of the pool to which the zone is bound, an error is returned.

sysconf(3C)

If the caller is in a non-global zone and the pools facility enabled, sysconf(_SC_NPROCESSORS_CONF) and sysconf(_SC_NPROCESSORS_ONLN) return the number of total and online processors in the processor set of the pool to which the zone is bound.

ucred_get(3C)

Added ucred_getzoneid() function, which returns the zone ID of the process or -1 if the zone ID is not available.

core(4)

Added n_type: NT_ZONENAME. This entry contains a string that describes the name of the zone in which the process was running.

pkginfo(4)

Now provides optional parameters and an environment variable in support of zones.

proc(4)

Added capability to obtain information on processes running in zones.

audit_syslog(5)

Added in<zone name> field that is used if the zonename audit policy is set.

privileges(5)

Added PRIV_PROC_ZONE, which allows a process to trace or send signals to processes in other zones. See zones(5).

if_tcp(7P)

Added zone ioctl() calls.

cmn_err(9F)

Added zone parameter.

ddi_cred(9F)

Added crgetzoneid(), which returns the zone ID from the user credential pointed to by cr.
