Commit be1bb6c95 changed the way volumes were stored from a forward
bcddb9
linked list to a hash table. In doing so, it required that each vol
bcddb9
object would have 3 unique values as keys into tables - key, name,
bcddb9
and path. Due to how vHBA/NPIV LUNs are created/used this resulted
bcddb9
in a failure to utilize all the LUN's found during processing.
bcddb9
bcddb9
During virStorageBackendSCSINewLun processing fetch the key (or
bcddb9
serial value) for NPIV LUN's using virStorageFileGetNPIVKey which
bcddb9
will formulate a more unique key based on the serial value and
bcddb9
the port for the LUN.
