How to Make Temporary Changes to the Running Zone

Review the following documentation:

• zonecfg Utility Edit Modes

• Temporary Changes to the Live Zone Configuration

• Appendix A, Resource Types and Global Properties That Support Live Zone Reconfiguration in Oracle Solaris Zones Configuration Resources

Perform this procedure to temporarily change the live configuration of a running zone and then restore the persistent configuration to undo the change.

1. On the global zone, become an administrator.

   For more information, see Using Rights Profiles to Install and Manage Zones.

2. Change the zone configuration.

   The sample command adds a disk in live mode and shows the command output.

   Note:

   The zonecfg commit command is not required. The zonecfg utility commits the changes when the command exits.

   global$ pfbash zonecfg -z kzone -r 'add device;set storage=dev:/dev/dsk/cNtXd;end'
   zone 'kzone': Checking: Adding device storage=dev:/dev/dsk/cNtXd
   zone 'kzone': Applying the changes

3. (Optional) When you no longer need the configuration change, return the zone to the persistent zone configuration.

   The sample command removes the temporary configuration change.

   global$ zoneadm -z kzone apply
   zone 'kzone': Checking: Removing device storage=dev:/dev/dsk/cNtXd
   zone 'kzone': Applying the changes

   Alternatively, you can reboot the zone to discard the live zone configuration changes and return to the persistent zone configuration.
