Field descriptions:
Volume Identification Template:
The Volume Identification Template field specifies a search template for translate functions and the
value of the new volume identification information for other Send Volume Tag command functions.
As a search template, this field may contain the wildcard characters ? and *. The ? shall match
any single character. The * shall match any string of characters. When it appears in a template the
remainder of the template at higher offsets in the field is not used. For assert, replace, or
undefined functions, the wildcard characters may not be used.
Minimum Volume Sequence Number:
The Minimum Volume Sequence Number field specifies the new sequence number for the assert
and replace functions. For a translate, this field specifies the least value in the volume sequence
number field of the volume tag information that meets the search specification.
Maximum Volume Sequence Number:
The Maximum Volume Sequence Number field specifies the maximum number value in the volume
sequence number field of the volume tag information that meets the search specification. This field
is ignored for assert, replace, and undefine functions.
