HP XP7 Disk Array Configuration Guide (H6F56-96003)

offers VxVM, which includes DMP. HP supplies HDLM. All these products provide multipath
configuration management, FCAs I/O load balancing, and automatic failover support, however
their level of configuration possibilities and FCAs support differs.
• For instructions on STMS, Storage Multipathing, or VxVM, see the manufacturers' manuals.
SNMP configuration
XP7 Storage support standard SNMP for remotely managing arrays. The SNMP agent on the 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 the XP7 Remote Web Console or XP7
Command View Advanced Edition Suite Software. For specific procedures, see the applicable
user guide.

RAID Manager command devices
The following applies to OpenVMS, HP-UX, IBM AIX, Linux, Solaris, VMware, and Windows.
• HP XP7 RAID Manager Software manages HP XP7 Business Copy Software or HP XP7
Continuous Access Synchronous Software operations from a host server. To use RAID Manager,
you must designate at least one LDEV as a command device. This can be done with the XP7
Remote Web Console or XP7 Command View Advanced Edition Suite Software. For information
about how to designate a command device, see the applicable user guide.
• Creating scripts to configure all devices at once could save you considerable time.
The following applies to OpenVMS.
When creating a command device, HP recommends creating a LUN 0 device of 35 megabytes
(the smallest allowed). This allows you to use host-based RAID management tools available from
HP, and will allow HP support to perform some additional diagnostics.
NOTE: Storage assigned to the LUN 0 device is not accessible to OpenVMS.
