To SANCP, the term "WWID", unless otherwise qualified, refers to
    the system's view of the set of all paths to a single port on a
    SAN storage device without regard to which drivers provide the
    paths. When a WWID is modified with the SET command, all paths
    are affected

    More generally, WWIDs are World-Wide unique Identifiers which are
    assigned to a FibreChannel port by its device's manufacturer. Each
    port will have a Node WWID and a Port WWID - since the Node WWID
    can be used to group Port WWIDs on the same device, only the Port
    WWID is guaranteed to be unique within a Fabric

1  –  WWID Formats

    A WWID passed to SANCP can be in any of the formats in which WWIDs
    are commonly displayed, so the output of any of the following
    commands can be easily cut & pasted into a SANCP command line:

    SDA> FC SHOW STDT

       WWID format 50001FE1000180b1

    SDA> FC SHOW WTID

       WWID format 5000.1FE1.0001.80A0

    $ SHOW DEVICE $1$DGA3420 /MULTI

       WWID format PGC0.5000-1FE1-0011-B15C

    The port specification in the SHOW DEVICE format will be ignored

2  –  WWID Wildcards

    A WWID term is a sequence of hex digits delimited by a period, a
    dash or the beginning or end of the string

    "%" can be  used any number of times, up to the legal length of a
    term, to wildcard a single hex digit

    "*" can  be used once within a term to wildcard 0 to N hex digits,
    but sequences of "*" will be collapsed to a single use and count as 1

    Legal wildcard uses:

       50*1000180b1
       *.*FE1.%%01.80A%
       PGC0.5%%0-1*1-0011-B15*

    Illegal wildcard uses:

       50*001*080b1         - too many multi-char wildcards
       5000.%%%%%.0001.80A0 - too many single-char wildcards
