HP StorageWorks XP Disk Array Mainframe Host Attachment and Operations Guide (A5951-96154, September 2010)

• 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 XP Remote
Web Console to monitor the SIMs.
