to as one-time file system migration. When ongoing file system migration between
multiple systems is desired, this is known as ongoing file system migration.
Different actions are required depending on the kind of migration, as described
in the following sections.
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:
os_name=name[,os_rel=release][,arch=arch_name]
[,vxfs_version=version][,bits=nbits]
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.
os_name=name
Specifies the operating system release version of the target.
For example, 11.31.
os_rel=release
Specifies the architecture of the target. For example, specify
ia or pa for HP-UX.
arch=arch_name
Specifies the VxFS release version that is in use at the target.
For example, 4.1 or 5.0.
vxfs_version=version
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.
bits=nbits
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.
