Creating LUSE Volumes
You can combine LDEVs to create LUSE volumes by specifying a spreadsheet that includes the
Expansion tag when you execute the CFLSET command using the CFL Extension.
Write parameters required for creating LUSE volumes in the Expansion tag. Parameters must be
written in a hierarchical structure by using the "+" identifier. Keep the following in mind while
writing parameters in the Expansion tag:
•
Number of LDEVs combined into a LUSE volume must be within the range of 2 to 36.
•
LDEV:CU:LDKC numbers of the top LDEVs in LUSE volumes must be arranged in ascending
order.
•
LDEV numbers of the LDEVs to be combined into a LUSE volume must be arranged in ascending
order.
“Structure and Identifier of Expansion Tag Parameters ” (page 34) shows the structure and the
identifier of the parameters that can be set for the Expansion tag.
