Specifying the migration target

Most of the operations performed by the CDS commands require the target to which the file system is to be migrated to be specified by target specifiers in the following format:


The CDS commands require the following target specifiers:


Specifies the name of the target operating system to which the file system is planned to be migrated. Possible values are HP-UX, AIX, SunOS, or Linux. The os_name field must be specified if the target is specified.


Specifies the operating system release version of the target. For example, 11.31.


Specifies the architecture of the target. For example, specify ia or pa for HP-UX.


Specifies the VxFS release version that is in use at the target. For example, 4.1 or 5.0.


Specifies the kernel bits of the target. nbits can have a value of 32 or 64 to indicate whether the target is running a 32-bit kernel or 64-bit kernel.

While os_name must be specified for all fscdsadm invocations that permit the target to be specified, all other target specifiers are optional and are available for the user to fine tune the migration target specification.

The CDS commands use the limits information available in the default CDS limits file, /etc/vx/cdslimitstab. If the values for the optional target specifiers are not specified, fscdsadm will choose the defaults for the specified target based on the information available in the limits file that best fits the specified target, and proceed with the CDS operation. The chosen defaults are displayed to the user before proceeding with the migration.


The default CDS limits information file, /etc/vx/cdslimitstab, is installed as part of the VxFS package. The contents of this file are used by the VxFS CDS commands and should not be altered.
