HP StorageWorks XP Disk Array Mainframe Host Attachment and Operations Guide XP24000, XP20000 (A5951 - 96151, September 2007)

DEVSERV PATHS. The DEVSERV PATHS command is defined as the number of LVIs that can be specified
by an operator (from 1 through 99). To display an entire storage system, enter the DEVSERV command
for several LVIs, as follows:
• DEVSERV PATHS,100,64
• DEVSERV PATHS,140,64
• DEVSERV PATHS,180,64
• DEVSERV PATHS,1C0,64
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 XP Remote Web Console to monitor
the SIMs.
Open-Systems Configuration
After physical installation of the storage system has been completed, the user configures the storage
system for open-system operations with assistance as needed from the HP representative. For specific
information and instructions on configuring the storage system disk devices for open-system operations,
see the XP disk array configuration guide for the connected platform. The following shows the currently
supported platforms. Contact your HP representative for the latest information on platform and operating
system version support.
UNIX-based platforms:
• IBM AIX
• HP-UX
• Sun Solaris
