console LUN console LUN ID container controller controller enclosure controller event controller pair corrective action code CRITICAL Condition CRU customer replaceable unit A SCSI-3 virtual object that makes a controller pair accessible by the host before any virtual disks are created. Also called a communication LUN. The ID that can be assigned when a host operating system requires a unique ID. The console LUN ID is assigned by the user, usually when the storage system is initialized. Virtual disk space that is preallocated for later use as a snapclone, snapshot, or mirrorclone. A hardware/software device that manages communications host systems and other devices. Controllers typically differ by the type of interface to the host and provide functions beyond those the devices support. A unit that holds one or more controllers, power supplies, fans, transceivers, and connectors. A significant occurrence involving any storage system hardware or software component reported by the controller to HP P6000 Command View. Two connected controller modules that control a disk array. See CAC. A drive enclosure EMU condition that occurs when one or more drive enclosure elements have failed or are operating outside of their specifications. The failure of the element makes continued normal operation of at least some elements in the enclosure impossible. Some enclosure elements may be able to continue normal operations. Only an UNRECOVERABLE condition has precedence. This condition has precedence over NONCRITICAL errors and an INFORMATION condition. Customer replaceable unit. A storage system element that a user can replace without using special tools or techniques, or special training. See CRU. D data entry mode data replication group failover default disk group Detailed Fault View device channel device ports device-side ports DIMM dirty data disk drive disk drive blank disk drive enclosure disk failure protection The state in which controller information can be displayed or controller configuration data can be entered. On the Enterprise Storage System, the controller mode is active when the LCD on the HSV Controller OCP is Flashing. An operation that reverses data replication direction so that the destination becomes the source and the source becomes the destination. Failovers can be planned or unplanned and can occur between DR groups or managed sets (which are sets of DR groups). The disk group created when the system is initialized. The disk group must contain a minimum of eight disks. The maximum is the number of installed disks. An HSV Controller OCP display that permits a user to view detailed information about a controller fault. A channel used to connect storage devices to a host I/O bus adapter or intelligent controller. The controller pair device ports connected to the storage system's physical disk drive array through the Fibre Channel drive enclosure. Also called a device-side port. See device ports. Dual Inline Memory Module. A small circuit board holding memory chips. The write-back cached data that has not been written to storage media even though the host operation processing the data has completed. A carrier-mounted storage device supporting random access to fixed size blocks of data. A carrier that replaces a disk drive to control airflow within a drive enclosure whenever there is less than a full complement of storage devices. A unit that holds storage system devices such as disk drives, power supplies, fans, I/O modules, and transceivers. A method by which a controller pair reserves drive capacity to take over the functionality of a failed or failing physical disk. For each disk group, the controllers reserve space in the physical disk pool equivalent to the selected number of physical disk drives. 282 Glossary
