5.1.12. Storage within a zone

[dd]Storage can be used in different ways in local zones. The type of use can be classified in the following ways:

∙Device or NFS

−Use thedevice in the local zone directly

∙Mount

−The global zone provides a file system per lofs to the local zone

−The global zone mounts a file system when the local zone is booted

−The zone mounts a file system from a device

∙Access

−read/write

−read only

−Share writable file system with several zones

5.1.12.1. Using a device in a local zone

[dd]If direct access to a device is required by the local zone, the device must be made available by the corresponding zone configuration. Once the zone has been restarted, the device entry is available under /dev, as seen from the local zone.

global# zonecfg -z zone1 zonecfg:zone1> add device zonecfg:zone1:device> set match=/dev/rdsk/c1d0s0 zonecfg:zone1:device> end

zonecfg:zone1> info device device:

match: /dev/rdsk/c1d0s0 zonecfg:zone1> commit zonecfg:zone1> exit

5.1.12.2. The global zone supplies a file system per lofs to the local zone

[dd]/export/globalhome of the global zone is to be mounted as writable in the local zone as /export/home. Since /export/globalhome is already available in the global zone, the file system can be added as a loopback filesystem. If the loopback filesystem is mounted as writable, both the global zone as well as zone1 can write on the file system.

global# zonecfg -z zone1 zonecfg:zone1> add fs

zonecfg:zone1:fs> set special=/export/globalhome zonecfg:zone1:fs> set dir=/export/home zonecfg:zone1:fs> set type=lofs zonecfg:zone1:fs> add options rw zonecfg:zone1:fs> info

fs:

dir: /export/home

special: /export/globalhome raw not specified

type: lofs

options: [rw] zonecfg:zone1:fs> end zonecfg:zone1>
