Sun Cluster Data Service for Solaris Containers Guide

Specifying Configuration Parameters for the Zone Boot Resource

Sun Cluster HA for Solaris Containers provides the script sczbt_register, which automates the process of configuring the zone boot resource. By default this script obtains configuration parameters from the sczbt_config file in the /opt/SUNWsczone/sczbt/util directory. To specify configuration parameters for the zone boot resource, copy the sczbt_config file to a different filename and amend it as described below. It is recommended to keep this file as a future reference. The register script provides option -f to specify the fully qualified filename to the copied configuration file.

Each configuration parameter in the sczbt_config file is defined as a keyword-value pair. The sczbt_config file already contains the required keywords and equals signs. For more information, see Listing of sczbt_config. When you edit the sczbt_config file, add the required value to each keyword.

The keyword-value pairs in the sczbt_config file are as follows:

RS=sczbt-rs
RG=sczbt-rg
PARAMETERDIR=sczbt-parameter-directory
SC_NETWORK=true|false
SC_LH=sczbt-lh-rs
FAILOVER=true|false
HAS_RS=sczbt-has-rs
Zonename=zone-name
Zonebootopt=zone-boot-options
Milestone=zone-boot-milestone
Mounts=list-of-mountpoints

The meaning and permitted values of the keywords in the sczbt_config file are as follows:

RS=sczbt-rs

Specifies the name that you are assigning to the zone boot resource. You must specify a value for this keyword.

RG=sczbt-rg

Specifies the name of the resource group the zone boot resource will reside in. You must specify a value for this keyword.

PARAMETERDIR=sczbt parameter directory

Specifies the directory name that you are assigning to the parameter directory where some variables and their values will be stored. You must specify a value for this keyword.

SC_NETWORK=true|false

Specifies whether the zone boot resource is network aware with a SUNW.LogicalHostName resource. You must specify a value for this keyword.

  • If HA for the zone's addresses is not required, then configure the zone`s addresses by using the zonecfg utility.


    SC_NETWORK=false
SC_LH=

  • If only HA through IPMP protection is required, then configure the zone`s addresses by using the zonecfg utility and then place the zone's addresses on an adapter within an IPMP group.


    SC_NETWORK=false
SC_LH=

  • If HA through IPMP protection and protection against the failure of all physical interfaces by triggering a failover is required, choose one option from the following list:

    • If you require the SUNW.LogicalHostName resource type to manage one or a subset of the zone's addresses, configure a SUNW.LogicalHostName resource for those zone's addresses and not by using the zonecfg utility. Use the zonecfg utility to configure only the zones's addresses that are not to be under the control of the SUNW.LogicalHostName resource.


      SC_NETWORK=true
SC_LH=Name of the SUNW.LogicalHostName resource

    • If you require the SUNW.LogicalHostName resource type to manage all the zone's addresses, configure a SUNW.LogicalHostName resource with a list of the zone`s addresses and do not configure them by using the zonecfg utility.


      SC_NETWORK=true
SC_LH=Name of the SUNW.LogicalHostName resources

    • Otherwise, configure the zone's addresses by using the zonecfg utility and configure a separate redundant IP address for use by a SUNW.LogicalHostName resource, which must not be configured using the zonecfg utility.


      SC_NETWORK=false
SC_LH=Name of the SUNW.LogicalHostName resource
SC_LH=sczbt-lh-rs

Specifies the name of the SUNW.LogicalHostName resource for the zone boot resource. Refer to Restrictions for Zone Network Addresses for a description of when to set this variable. This name must be the SUNW.LogicalHostname resource name you assigned when you created the resource in Step 4.

FAILOVER=true|false

Specifies whether the zone`s zone path is on a highly available file system.

HAS_RS=sczbt-has-rs

Specifies the name of the SUNW.HAStoragePlus resource for the zone boot resource. This name must be the SUNW.HAStoragePlus resource name you assigned when you created the resource in How to Enable a Zone to Run in a Failover Configuration. You must specify a value for this keyword if FAILOVER=true is set.

Zonename=zone-name

Specifies the zone name. You must specify a value for this keyword.

Zonebootopt=zone-boot-options

Specifies the zone boot option to use. Only -s is supported. Leaving this variable blank will cause the zone to boot to the multi-user-server milestone.

Milestone=zone-boot-milestone

Specifies the milestone the zone must reach to be considered as successfully booted. You must specify a value for this keyword.

Mounts=list-of-mountpoints

Specifies a space separated list of directories with their mount options, which will automatically get lofs mounted from the global zone into the booted zone. The mount point used in the global zone can be different to the mount point in the booted zone. Specifying a value for this keyword is optional.

The Mounts keyword format is as follows:


Mounts="/global-zone-dir:/local-zone-dir:mount-options <next entry>"

While mount-options can be a comma separated list of file system mount options.

The only required entry when setting this keyword is the /global-zone-dir part of the colon separated variable. The /local-zone-dir and mount-options part can be omitted.

Omitting the /local-zone-dir part will make the zone`s mount point the same as the global zone directory.

Omitting the mount-options part will not provide any mount options except the default options from the mount command.

Note –

You must manually create any mount point directories within the booted zone that will be used within the Mounts keyword, before registering this resource within Sun Cluster.

Note –

If the file system of the source mount point in the global zone is mounted by a SUNW.HAStoragePlus resource, you must specify a strong resource dependency from the sczbt resource to this SUNW.HAStoragePlus resource.

Example 1 Sample sczbt_config File

This example shows an sczbt_config file in which configuration parameters are set as follows:

RS=zone1-rs
RG=zone1-rg
PARAMETERDIR=/global/zones/pfiles
SC_NETWORK=true
SC_LH=zone1-lh
FAILOVER=true
HAS_RS=zone1-has
Zonename=zone1
Zonebootopt=
Milestone=multi-user-server
Mounts="/global/app/bin:/app/bin:ro /app/data:rw /logs"
