HP StorageWorks Storage System Scripting Utility reference (September 2005)

WORLD_WIDE_LUN

_NAME=

This sets the World Wide LUN Name on unpresented storage (either ACTIVE or snapshot). This switch is

rejected when issued against storage that is presented to a host.

NOTE:

This switch is c

ommonly used to allow a host to point to a new version of a snapshot by giving the new

snapshot the same WWN as the old snapshot.

WRITE_PROTECT

This does not allow writing to the virtual disk for all presented LUNs.

WRITE_CACHE=

This is the cache para m eter for the write operation. There are two values: W RITETHROUGH and

WRITEBACK. With WRITETHROUGH the operation comp letes when the write to disk c ompletes. With

WRITEBACK, the operation completes when the da ta is written to cache.

NOWRITE_PROTECT

This allows wr iting to the v irtual disk for all presented L UNs.

Example

SET VDISK “\Virtual Disks\archive\ACTIVE”

WORLD_WIDE_LUN_NAME=6000-1fe1-ff00-0000

This example assigns the World Wide LUN Name to the ACTIVE virtual disk of the archive family.
