HP StorageWorks Disk Array XP operating system configuration guide for Windows 2000/2003 XP24000, XP12000, XP10000, SVS200, v01 (A5951-96195, June 2007)

Device emulation types
The XP family of disk arrays supports these device emulation types:
• OPEN-3/8/9/E/L/V devices: OPEN-x logical units represent disk devices. Except for OPEN-V,
these devices are based on fixed sizes. OPEN-V is a user-defined size. Supported emulations
include OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V devices.
• LUSE devices (OPEN-x*n): Logical Unit Size Expansion (LUSE) devices combine 2 to 36 OPEN-x
devices to create expanded LDEVs larger than standard OPEN-3/8/9/E/L/V disk devices. For
example, an OPEN-x LUSE volume created from ten OPEN-x volumes is designated as OPEN-x*10.
• CVS devices (OPEN-x CVS): Volume Size Configuration (VSC) defines custom volumes (CVS) that
are smaller than normal fixed-sized logical disk devices (volumes). (OPEN-V is a CVS-based custom
disk size that you determine. OPEN-L does not support CVS.)
• LUSE (expanded) CVS devices (OPEN-x*n CVS): LUSE CVS combines CVS devices to create an
expanded device. This is done by first creating CVS custom-sized devices and then using LUSE to
combine from 2 to 36 CVS devices. For example, if three OPEN-9 CVS volumes are combined to
create an expanded device, this device is designated as OPEN-9*3-CVS.
NOTE:
For the SVS200, and the XP24000/XP12000/XP10000 when connected to external storage devices, HP
recommends using OPEN-V as the emulation the array makes visible to the host. This allows configuration
of external storage LDEVs without losing data. Using any other emulation may cause data loss in the
external storage LUNs.
Refer to Table 10 on page 30 for detailed information.
Failover
The disk arrays support many standard software products that provide host, application, or I/O path
failover and management.
SNMP configuration
The XP family of disk arrays and the SVS200 support standard Simple Network Management Protocol
(SNMP) for remotely managing arrays. The SNMP agent on the service processor (SVP) performs
error-reporting operations requested by the SNMP manager. SNMP properties are usually set from
the SVP but they can also be set remotely using XP Command View (XP arrays only), XP Remote Web
Console, or Command View XP Advanced Edition Software. Refer to the applicable user's guide for
procedures.
