38Storage Foundation and High Availability Solutions support for Solaris ZonesConfiguring VCS in zones■■Verify your VCS credentials. Make sure the password is not changed.Verify the VxSS certificate is not expired.■Resource does not come online in the zone.Recommended actions:■■■Verify VCS and the agent packages are installed correctly.Verify the application is installed in the zone.Verify the configuration definition of the agent.Configuring for physical to virtual and virtual to physical failovers—atypical setupIn this configuration, you have two physical nodes. One node runs Solaris 10without zones configured (sysA) and another node runs Solaris 10 with zonesconfigured (sysB).Figure 2-5An application service group that can fail over into a zone and backWhile the Zoneresource isneeded, it doesnot manage areal entitysysAApplicationZonesysBApplicationZoneThe Applicationresource residesin the nonglobalzoneMountMountDiskGroupDiskGroupSolaris 10 Solaris 10In the main.cf configuration file, define the container name, type of container,and whether it is enabled or not in the service group definition.ContainerInfo@sysA = {Name = Z1, Type = Zone, Enabled = 2}ContainerInfo@sysB = {Name = Z1, Type = Zone, Enabled = 1}On sysA, set the value of Enabled to 2 to ignore zones so that the application runson the physical system. When the service group fails over to sysB, the applicationruns inside the zone after the failover because Enabled is set to 1 on sysB. Theapplication can likewise fail over to sysA from sysB.When ContainerInfo::Enabled is set to 2, the Zone agent reports resource statebased on state of the corresponding group. Currently, the Zone agent check the
Storage Foundation and High Availability Solutions support for Solaris ZonesAdding VxFS file systems to a non-global zone39state of the group on all the systems. If group is online on any of the nodes in thecluster Zone resource is reported as online. This triggers concurrency violationissue. The Zone agent should look for group state on local system.Note: IMF must be disabled on the node where Enable is set to 2 (sysA in thisexample). To disable IMF, set the mode to 0.Adding VxFS file systems to a non-global zoneVxFS file systems that were previously created in the global zone can be madeavailable in the non-global zone using a loopback file system mount. Thisfunctionality is especially useful when the sole purpose of making the file systemavailable in the non-global zone is to share access of this file system with one ormore non-global zones. For example, if a configuration file is available in aparticular file system and this configuration file is required by the non-globalzone, then the file system can be shared with the non-global zone using a loopbackfile system mount.The following commands share access of file system /mnt1 as a loopback filesystem mount with an existing non-global zone myzone:# zonecfg -z myzonezonecfg:myzone> add fszonecfg:myzone:fs> set dir=/mnt1zonecfg:myzone:fs> set special=/mnt1zonecfg:myzone:fs> set type=lofszonecfg:myzone:fs> endzonecfg:myzone> verifyzonecfg:myzone> commitzonecfg:myzone> exitThe value of dir is a directory in the non-global zone. The value of special is adirectory in the global zone to be mounted in the non-global zone.Caution: Sharing file systems with non-global zones through a loopback filesystem mount makes the file system available for simultaneous access from allthe non-global zones. This method should be used only when you want sharedread-only access to the file system.The loopback file system mount mode of sharing file systems in the non-globalzones is supported in Veritas File System 4.1 and later.
