That is, cache can beset on or off for individual devices whether the cache is on oroff for the subsystem. However, if the cache is set off for thesubsystem, setting cache on for an individual device has noeffect until the cache is set on for the subsystem.PENDINGOFFspecifies a recovery command to allow cache or DASD fast write to aparticular device to be set off when cache or DASD fast write is inpending state.Abbreviation: PEND.Chapter 31.
