About displaying the status and statistics of disks

Management display

You can view the status of disks on your appliance using the Disk - Management page (Maintenance tab > Disk > Management) of the Appliance Manager.

Note
The Appliance Manager does not display the Disk - Management page for NetCache C1100 or C1105 appliances. It does display this page for all other NetCache appliances.

The following table describes the different columns in the Disk - Management page output.

Output heading	Description
Host Adapter	Indicates the host adapter number, which is the number of the slot in which the disk adapter is installed.
Shelf	Shelf is the number of the disk shelf that is connected to the disk adapter interface on the host adapter. Multiple disk shelves can be connected to a disk adapter interface if the disk adapter is a differential SCSI adapter or a fibre channel adapter. The disk shelf number starts at 0.
Type	Indicates the type of disk adapter. For example, Fibre Channel and SCSI.
Bay	Bay is the number of the disk slot in the disk shelf, which starts at 0.
Disk ID	Disk ID is represented in the x.y format, where x is the host adapter and y is the disk number. For more information, see Disk addresses.
Size	Size of the disk in megabytes. The disk sizes are "right-sized," as explained in Disk space on each disk.
Disk Type	Indicates the current function of the disk. A disk can be a data, spare, or parity disk.
Disk Operations	The operations allowed on the disks in the appliance. The Fail operation changes the state of a disk to "Bad." The Promote operation promotes a spare disk to a file system disk, as explained in the Appliance Manager online Help.

Disk statistics

You can view the disk statistics of your appliance using the System Status - General page (Data tab > System Status > General) in the Appliance Manager. The options that display disk statistics on the System Status - General page are as follows:

Disk Space in Use--Displays the amount of disk space consumed by objects stored on the appliance.
Total Disk Space--Displays the total amount of data disk space available on a appliance. The disk space indicated by this option does not include the disk space of the parity disk.
