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.
