Detailed Information for Disk <n>

Use this window to view information about the volumes, virtual disks, and array disks that are present on a particular disk.

Volume Information

A volume is a logical/virtual entity that is made up of portions of one or more operating system disks. A volume can be formatted and may have a file system and/or drive letter.

Status Whether the event type for the volume is Normal/OK, Warning/Noncritical, and Critical/Failure.
Name String that names the volume; for example, utility partition.
State Volume states include: Ready, Failed, Online, Offline, Degraded, Recovering, Removed, Resynching, Rebuilding, Reconstructing, Unknown.
File System Major file system types include the NT File System (NTFS) and File Allocation Table (FAT).
Size Total space on the volume in gigabytes (GB).
NOTE: To update the amount of free space available on a particular disk, click Go Back to OS Disks Page and then click Update Disk(s) Information. When you select the disk again, the Free Space value displays the updated space available on the disk.
Free Space Amount of storage that remains unused on the volume in GB.

Virtual Disks

A virtual disk is an abstract entity used by Array Manager that allows you to use different hardware RAID layouts on selected array disks. Virtual disks are hardware RAID logical drives. After the virtual disk is created and the system is rebooted, the virtual disk appears as a disk in Microsoft® Windows NT® and in Windows® 2000. When running applications, a virtual disk works the same as a physical disk.

Status Whether the event type for the virtual disk is Normal/OK, Warning/Noncritical, and Critical/Failure.
Name String that names the device; for example, Virtual Disk 0.
State States of the disk include: Ready, Failed, Online, Offline, Degraded, Recovering, Removed, Resynching, Rebuilding, Reconstructing, Unknown.
Read Cache The read policies are as follows: Read-Ahead, No-Read-Ahead, and Adaptive Read-Ahead. For definitions, see Read Policies.
Write Cache The write policies are as follows: Write-Back Caching and Write-Through Caching. For definitions, see Write Policies.
Cache Policy Cache Policies include Direct I/O and Cache I/O. Cache policies apply to reads on a specific logical drive. These settings do not affect the read-ahead policy. For definitions, see Cache Policies.
Layout The layout, or hardware RAID level, includes Concatenation, RAID 0, RAID 1, RAID 5, RAID 10, RAID 50, and Concatenation of RAID 1.
Size Amount of storage on the disk in GB.

Array Disks

An array disk is a physical disk controlled by a RAID controller. These disks can be placed in an array group, and virtual disks can be created from them.

Status Whether the event type for the virtual disk is Normal/OK, Warning/Noncritical, and Critical/Failure.
Name String that names the device.
State Disk states include: Ready, Failed, Online, Offline, Degraded, Recovering, Removed, Resynching, Rebuilding, Reconstructing, Unknown.
Controller Name of the RAID controller that controls the disk.
