Figure 11-137. Logical Drive Information Window ICP RAID Navigator Drive No Drive Name Type Status Capacity Attributes Last Status RAID 1 Component RAID 4/5 Component The number of the logical drive. The name of the logical drive. The type of the logical drive. A logical drive can be either a single disk, or a chaining group of disks (concatenation), or a stripe set of several disks. This is the state of the logical drive. It can be ready, missing (not available after reset) or failed (for example, no longer available for the controller). The available capacity of array drives or host drives. The attribute of a logical drive is usually read/write ([RW]). If a component of a disk array is missing during startup and the operator decides not to activate fail mode, the array is set to the read only attribute ([RO]). When the missing drive becomes available, the array drive shows the ready status (for example, attribute [RW]). The last status information of a logical drive. This is different from the last status information of physical drives. If the logical drive is a member of a RAID 1 array, it can be either master or slave. If a RAID 1 component is added to a logical drive, the data is read from the master and written to the added logical drive (the slave). One master may have several slaves. As a member of a RAID 4 or RAID 5 array a logical drive can be the master or a component. Different from RAID 1 arrays, this is only important for the internal structure of the array. 11.5.8 Drive Name Click the right mouse button on the icon for a host drive, array drive, or logical drive. This menu option opens a dialog for entering a new name for the selected drive (up to 7 characters). Software Installation and User's Guide 177
