Ykscan Command - HP XP P9500 Reference Manual

The range from the FROM parameter to the TO parameter is scanned in hexadecimal ascending
order.
FROMVSN(volser) ~ <from 1 to 6 alphanumeric characters>
Specify the volume serial number of the first volume to be scanned.
This parameter and the FROM and TO parameters are mutually exclusive.
TOVSN(volser) ~ <from 1 to 6 alphanumeric characters>
Specify the volume serial number of the last volume to be scanned.
This parameter and the FROM and TO parameters are mutually exclusive.
The range from the FROMVSN parameter to the TOVSN parameter is scanned in EBCDIC order.
MSG(stem-name-2) ~ <REXX prefix of 64 or fewer characters>
Specify an optional prefix for the name of the message structure used to store the messages to be
generated by this command. You must also include a trailing period character.
The message structure is initialized when the CLI command with the same name as the MSG
parameter is specified.
ARRAYS(stem-name-3) ~ <REXX prefix of 64 or fewer characters>
Specify an optional prefix for the name of the Host-Discovered Array Index structure. You must
also include a trailing period character.
The YKSCAN command returns the number of storage systems detected to
stem-name-specified-in-ARRAYS-parameter0, and returns the information about the nth detected
storage system to the corresponding REXX variable (the REXX variable with the name formed by
appending n to the stem name specified by the ARRAYS parameter).
NOTE:
Before creating a copy group, use the YKSCAN command to obtain the information on the
volumes available on this site.
If storage system functions or information such as the Software Keys or microcode number is
changed, storage system information should be obtained again by using the YKSCAN command.
In this case, at least one volume is scanned once, and storage system information can be
obtained.
The alias volume (PAV-Alias) bound to a parallel access volume (PAV) is not scanned.
