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:
os_name=name[,os_rel=release][,arch=arch_name] [,vxfs_version=version][bits=nbits]
The CDS commands require the following target specifiers:
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.
