Failover; Snmp Configuration; Raid Manager Command Devices - HP XP1024 System Configuration Manual

Failover

The XP family of disk arrays supports many standard software products that provide host,
application, or I/O path failover and management. TruCluster is one of the supported
applications.
CAUTION:
Tru64 verson 5 fully supports dynamic load balancing and failover when multiple HBAs
are connected to the same LUN. This feature is ONLY available with version 5. On
Tru64 version 4, DO NOT connect multiple HBAs to the same LUN and DO NOT allow
the same LUN to be accessible from multiple HBAs on Tru64 version 4 hosts. ON the
version 4 system, this will allow multiple device names to access the same LUN. If both
device names are used, data corruption will result.
SNMP configuration
The XP family of disk arrays supports standard Simple Network Management Protocol
(SNMP) for remotely managing the disk array. 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 Remote Web Console
XP, Command View XP, or Command View XP Advanced Edition. Refer to the applicable
user's guide for procedures.

RAID Manager command devices

RAID Manager manages Business Copy (BC) or Continuous Access (CA) operations
from a host server. To use RAID Manager with BC or CA, you use Remote Web Console,
Command View, or Command View XP Advanced Edition to designate at least one LDEV
as a command device. Refer to the applicable user's guide for information about how to
designate a command device.
