XP Storage Systems
URz operations involve the XP storage systems at the primary and secondary sites. The primary storage
system consists of the main control unit (primary storage system) and SVP. The secondary storage system
consists of the remote control unit (secondary storage system) and SVP.
To provide greater flexibility and to enable the XP disk array to be tailored to unique customer operating
requirements, operational parameters, or optional modes, are available in URz for the XP storage system.
At installation, the XP disk array modes are set to their default values, so make sure to discuss these
settings with your HP team. The XP disk array modes can only be changed by your HP representative.
