Using Adaptec Storage Manager – Browser Edition Pop-Up Tool Tips If you position the cursor over a device or button a pop-up tool tip appears. For buttons, the tips contain helpful information about the function of the button, while for devices they display additional information. Physical Devices The Physical Devices view displays information about the drives and enclosures attached to the Adaptec RAID controller.
Using Adaptec Storage Manager – Browser Edition If you change the display mode by selecting one of the other view buttons, a yellow arrow flashes to the left of any devices where the condensed display prevents omits information. An icon is always the first entry on each device line. The icon is used to represent a hard disk drive. If a + symbol appears with the hard disk drive icon , the drive is a hot spare. Different icons are used to represent other devices.
Using Adaptec Storage Manager – Browser Edition This is done because hard disk drives of apparently the same capacity from different manufacturers, or even different models from the same manufacturer, actually vary slightly in the true capacity available. Although, in normal operation this is not an issue, it can be when assigning hot spares or replacing a failed drive.
Using Adaptec Storage Manager – Browser Edition If a global hot spare exists, all arrays that the hot spare is large enough to protect will show as protected. In the expanded view, the icons for the arrays are arranged vertically and alongside them are the capacity, name, and type of array. Selecting an array by clicking on it will highlight the following in amber: ■ All the drives or segments that form the array in the Physical Devices view.

Glossary A activity See task. ACU Array Configuration Utility. An application used to create, configure, and manage arrays from the controller’s BIOS or MS-DOS. array A logical disk created from available space and made up of one or more segments on one or more physical disks. Arrays are typically used to provide data redundancy or enhanced I/O performance. See also volume, spanned volume, RAID 0, RAID 1. Also known as a container. array initialization See initialize. ATA AT Bus Attachment.
Glossary B background consistency check Option that forces the controller to constantly check all portions of disks used by all arrays to see if the disks can return data from the blocks. See also consistency check command. bad segment Segment that is in an unknown state. bootable array Array configured as the boot device. build Background initialization of a redundant array. The array is accessible throughout. RAID 1 copies the contents of the primary drive to a secondary drive. See also clear.
Glossary clear Foreground initialization of a fault-tolerant array. A clear operation zeros all blocks of the array. The array is not accessible until the clear task is complete. concatenation Joining of physical or logical drives in sequential order. consistency check command Command that reads all the blocks of a RAID 1 to determine if the blocks are consistent. Any inconsistent blocks are fixed. D dead partition See failed.
Glossary E event Notification or alert from the system, indicating that a change has occurred. event log File used to maintain information about prior controller activities or errors. event notification Process for transmitting events. F failed State of a nonredundant array that has suffered a single drive failure, or a redundant array that has suffered multiple drive failures. A failed array is inaccessible and data is lost.
Glossary I impacted An impacted array is one which has been created but for some reason the initial build operation did not complete. All member drives are present and operational, and all data written to the array is protected. To optimize the array, run a Verify with Fix Task. initialize Process of preparing a disk for use by the controller. When a disk is initialized, the controller records the RAID signature on the disk. initialized array An array that is ready for data reads and writes.
Glossary O offline array Array that can no longer be accessed. optimal The state of an array when it is fully operational. For redundant arrays, the entire array is protected. P partition A section of a disk storage device created by the operating system disk management program, in which data and/or software programs are stored. Computers have a primary operating system partition that contains the special files needed to boot the computer.
Glossary RAID 0 A single-level array consisting of two or more equal-sized segments residing on different disks. RAID 0 distributes data evenly across its respective drives in equal-sized sections called stripes. RAID 0 arrays are not redundant. RAID 1 Single-level array consisting of two equal segments residing on two different drives. Provides redundancy by storing identical copies on two drives. See also mirrored array/mirroring.
Glossary single-level array Array created from one or more segments. See also volume, spanned volume, RAID 0, RAID 1. snapshot Instantaneous read-only copy of an array at a precise point in time. spanned volume A simple volume that spans two or more drives. stripe Contiguous set of data distributed across all the disks in an array. A striped array distributes data evenly across all members in equalsized sections called stripes. stripe size The amount of data in each section of a striped array.
Glossary volume See simple volume, spanned volume.
