zVM (VM/ESA) Cache operations
When the storage system 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
zVSE (VSE/ESA) Cache operations
When using VSE/ESA to manage the storage system, 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. Because
the RAID technology and dynamic spare drives ensure non-stop processing, a drive failure may
not be noticed by the console operator. If C-Track is not installed, the user should run and read an
EREP SIM report on a regular basis. Because all SIMs are also logged on the SVP, the user can
also use the Remote Web Console to monitor the SIMs.
