HP StorageWorks Disk Array XP operating system configuration guide for Sun Solaris XP24000, XP12000, XP10000, SVS200, v01(A5951-96037, June 2007)

Fibre Channel interface
The XP family of disk arrays and the SVS200 support these Fibre Channel elements:
• Connection speeds of 1 Gbps, 2 Gbps, and 4 Gbps (not available for the SVS200)
• Short-wave non-OFC (open fiber control) optical interface
• Multimode optical cables with SC or LC connectors
• Public or private arbitrated loop (FC-AL) or direct fabric attach
• Fibre Channel switches
Even though the interface is Fibre Channel, this guide uses the term “SCSI disk” because disk array
devices are defined to the host as SCSI disks.
Device emulation types
The XP family of disk arrays and the SVS200 support these device emulation types:
• OPEN-x 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-x 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 7 on page 34 for detailed information.
Failover
The disk arrays support many standard software products that provide host, application, or I/O path
failover and management. The VERITAS Cluster Server and Sun Cluster host failover products are
supported for the Sun Solaris operating system. Refer to the documentation for these products and
Sun technical support for installation and configuration information. Your HP representative may have
to set specific disk array System Modes for these products.
For I/O path failover, different products are available from Sun, Veritas and HP. Sun supplies software
called Sun StorEdge Traffic Manager (STMS) for Solaris 8/ 9 and Storage Multipathing for Solaris
10. Veritas offers Veritas Volume Manager (VxVM) which includes Dynamic MultiPathing (DMP). HP
