46 Continuous Access XP Journal
Installing hardware
You and the HP representative initially install the Continuous Access XP Journal hardware. To install the
hardware required for Continuous Access XP Journal operations:
1. User: Identify the locations of Continuous Access XP Journal’s primary and secondary data volumes
(primary data volumes and secondary data volumes), so the Continuous Access XP Journal hardware
can be installed and configured properly.
2. HP Representative: Ensure that the primary and secondary disk arrays are configured for Command
View XP or XP Remote Web Console operations (for example, SVP is connected to the LAN).
3. HP Representative: Ensure that the primary and secondary disk arrays are properly configured for
Continuous Access XP Journal operations (for example, cache and NVS) (see ” Cache and nonvolatile
storage (NVS) ” on page 40). Ensure that the desired SVP modes are enabled (see Table 3 on
page 25). Ensure that adequate cache is installed and available for Continuous Access XP Journal
operations. You must also consider the amount of HP Cache LUN XP data to be stored in cache when
determining the required amount of cache.
4. HP Representative: Ensure that the primary disk arrays are configured to report sense information to the
hosts. The secondary disk arrays should also be attached to a host server to enable sense information
reporting if a problem with an secondary data volume or secondary disk array occurs. If the remote
site is unattended, the secondary disk arrays should be attached to a host server at the primary site, so
the system administrator can monitor the operational condition of the secondary disk arrays.
5. HP Representative: If power sequence control cables are used, set the power select switch for the cluster
to LOCAL to prevent the host from powering off the primary disk array. Also ensure that the secondary
disk array will not be powered off during Continuous Access XP Journal operations. See ” Power
management for disk arrays and network relay devices ” on page 143 for more information about
powering off and on the primary and secondary disk arrays.
