created on the same disk array. A numeric value is assigned to a LUN at the time it is created. LVD-SCSI Low voltage differential implementation of SCSI. Also referred to as Ultra2 SCSI. LVM (Logical Volume Manager) The default disk configuration strategy on HP-UX. In LVM one or more physical disk modules are configured into volume groups that are then configured into logical volumes. loop address The unique ID of a node in Fibre Channel loop topology, sometimes referred to as a Loop ID. MIA Media interface adapter, a device that allows you to connect fiber optic cable to a copper wire connector. mirrored disks A mirrored disk is an exact copy of another disk. Mirrored disk are used when implementing the data redundancy technique of mirroring. See mirroring. mirroring A technique which creates data redundancy by maintaining a duplicate copy of all data stored on the disk array. The mirror copy of data is available if the disk containing the original data fails or becomes inaccessible. RAID 1 and RAID 0/1 LUNs use mirroring. NVSRAM The disk array controller stores operating configuration information in this non-volatile SRAM (referred to as NVSRAM). The contents of NVSRAM can only be accessed or changed using special diagnostic tools. path See primary disk array path or primary path. 399 Glossary
