Resources available for each function
The Remote Web Console secondary window shows all the resources in the storage system.
However, the functions described in this manual are only available to the resources that are assigned
to the account of users who log into Remote Web Console. Verify the resource group ID in the
Report Display dialog boxes, and then execute the operations for the resources assigned to the
user account. When you use the functions, the resources for each operation must satisfy the specific
conditions.
For details about user accounts, see the HP XP7 Remote Web Console User Guide.
For details on the conditions of the resources, see the HP P9000 Provisioning for Open Systems
User Guide or the HP P9000 Provisioning for Mainframe Systems User Guide.
System Configuration
Compatible XRC operations require hosts and storage systems at the primary and secondary sites.
If operation at the secondary site is required, the secondary storage system (or systems) must be
capable of supporting the XRC workload. If the system at the primary site consists of several hosts,
a SYSPLEX timer is required in the primary host to provide a common time reference for the I/O
time-stamping function. The secondary host requires the SDM host software for remote copy
operations. The Compatible XRC feature needs to be installed in the primary storage system, and
the Remote Web Console is required at the primary site for setting XRC options.
The following figure shows the connection configuration of channel extenders for Compatible XRC
operations.
