4.3.4 VM/ESA

®

Cache Operations

When the 9900 is managed under VM/ESA

®

, the following SET CACHE commands are effective

across multiple SSIDs:

SET CACHE SUBSYSTEM ON|OFF
SET NVS SUBSYSTEM ON|OFF
SET CACHEFW SUBSYSTEM ON|OFF
DESTAGE SUBSYSTEM

4.3.5 VSE/ESA Cache Operations

When using VSE/ESA to manage the 9900, the following CACHE commands are effective
across multiple SSIDs:

CACHE SUBSYS=cuu,ON|OFF|STATUS
CACHE SUBSYS=cuu,FAST,ON|OFF
CACHE SUBSYS=cuu,NVS,ON|OFF
CACHE SUBSYS=cuu,REINIT

Note: SIMs indicating a drive failure may not be reported to the VSE/ESA console (reference
IBM

®

document GA32-0253). Since the RAID technology and dynamic spare drives ensure non-

stop processing, a drive failure may not be noticed by the console operator. If Hi-Track

®

is

not installed, the user should run and read an EREP SIM report on a regular basis. Since all
SIMs are also logged the 9900 Remote Console PC, the user can also use the Remote Console
PC to monitor the SIMs.
