Volume Manager guidelines
The following are the specifications and restrictions on LDEVs used to configure a LUSE volume:
•
Open volumes (OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V) are supported.
•
The number of LDEVs combined into a LUSE volume must be within the range of 2 to 36.
NOTE:
The number of expanded LUs (LDEVs) should not exceed 36, even if the LUSE volume contains
another LUSE volume.
•
The emulation type of LDEVs combined into a LUSE volume must be the same.
•
The RAID level of LDEVs that are to be combined into LUSE volumes should be the same. (Recom-
mended).
NOTE:
Combining RAID-1 and RAID-5 volumes into the same LUSE volume is supported, but not
recommended.
•
LDEVs or LUSE volumes to be combined must not have assigned path definitions. For this reason,
Hitachi TrueCopy for z/OS, Continuous Access XP, Hitachi ShadowImage for z/OS, Business
Copy XP, and Continuous Access XP Journal pair volumes cannot be targets of Volume Manager
operations (see
Volume Manager operations using a path-defined LDEV
).
•
LDEVs to be combined into LUSE volumes must not be reserved for Auto LUN XP.
•
When combining a LUSE volume with another LUSE volume, the range of LDEVs should not overlap.
