Preparing for System Migrations Using the zonep2vchk Tool

This section describes the zonep2vchk tool. The primary documentation for the tool is the zonep2vchk(1M) man page.

About the zonep2vchk Tool

The P2V process consists of archiving a global zone (source), and then installing a non-global zone (target) using that archive. The zonep2vchk utility must be run with an effective user id of 0.

The utility does the following:

• Identifies problem areas in the source system's configuration

• Minimizes the manual reconfiguration effort required

• Supports migration of both Oracle Solaris 10 and Oracle Solaris 11 system images into zones on Oracle Solaris 11 releases

• Supports complex network configurations in the original system image, including multiple IP interfaces, IP multipathing, and VLANs

This tool can be used to migrate an Oracle Solaris 11 physical system or an Oracle Solaris 10 physical system into a non-global zone on this release:

• Migrate an Oracle Solaris 11 system into a solaris brand zone

• Migrate an Oracle Solaris 10 system into a solaris10 brand zone

For Oracle Solaris 11 target systems, an add anet resource (VNIC) is included in the zonecfg output for each network resource on the source system. By default, exclusive-IP is the network type when migrating either an Oracle Solaris 11 system or an Oracle Solaris 10 system into a non-global zone on an Oracle Solaris 11 system.

Types of Analyses

Basic analysis, the -b option, checks for Oracle Solaris features in use that might be impacted by P2V migration.

Static analysis the -s option, inspects binaries for system and library calls that might not function in a zone.

Runtime analysis, the -r option, inspects the currently executing applications for operations that might not function in a zone.

Information Produced

Two main categories of information are presented by the analysis:

• Issues that can be addressed with a specific zone configuration or with configuration changes in the global zone

• Identification of functions that cannot work inside a zone

For example, if an application sets the system clock, that can be enabled by adding the appropriate privilege to a zone, but if an application accesses kernel memory, that is never allowed inside a zone. The output distinguishes between these two classes of issues.

By default, the utility prints messages in human readable form. To print messages in machine parsable form, the -P option is used. For complete information on available options as well as command invocation and output, see the zonep2vchk(1M) man page.
