The Array Information Category

The Array Information category provides easy access to information about every aspect of system operation.

Enclosure view Displays the physical view of all major components, including drive slots and enclosure components.

Tasks under process Ongoing tasks being processed by the subsystem, e.g., array initialization.

Logical drive information

Displays information of all configured arrays, including the RAID levels applied and the graphical display of member drive locations.

Logical volume information

Displays information on all configured logical volumes.

Fibre Channel status Shows information of Fibre host channels, including link status, WWN port names, node names, etc.

System information Is a real-time display of the RAID controller/subsystem operation status, including board temperature, voltage, battery, etc.

Statistics Graphical and numeric representations of system performance in terms of cache hits and current read/write throughput.

5-12 The Array Information Category

To access each information window, single-click its corresponding icon on the navigation tree located on the upper left of GUI screen.

5.5.1 Accessing the Enclosure View

To open the Enclosure View window either select the Enclosure icon from the configuration tree or select the Enclosure command from the Enclosure View as shown in Figure 4- 11. The command allows you to access the graphical display of the enclosure’s front and rear view window. If multiple enclosures have been cascaded, you can select a different enclosure by clicking its tab-like icons as displayed below.

Figure 4- 11: Enclosure Tabbed Panel

Select an enclosure and start viewing devices in the enclosure view window.

5.5.2 Using the Enclosure View Window

Both enclosure windows present a graphical display of different components. The Enclosure window is particularly useful in monitoring the status of the physical drives. It provides you with a real-time report on the drive status, using LED colors to represent various operating conditions.

You can also display some information about a particular drive or enclosure module by placing the mouse pointer on its respective icon. Message tags, similar to those shown in Figure 4-13, appear.

Figure 4-13: Component Information Message Tags

This readout displays the current configuration of the drive, including the channel number of the drive slot on the subsystem to which the drives are connected, the drive’s capacity, transfer rate, and current status. The message tag for enclosure components displays the operating status.

The Information Summary window displays key information of the subsystem currently selected, including the RAID controller(s), I/O channels, and LUN mapping status.

5.5.3 Using the Tasks Under Process Window

The Tasks Under Process window reminds a user of unfinished tasks being processed by a subsystem. The start time and percentage of progress are also displayed on screen.

5.5.4 Using the Logical Drive Information Window

The Logical Drive Information window provides the configuration, management, and monitoring functions available in RAIDWatch. The Logical Drive View window includes three sub-windows: Logical Drive Status, Front View, and Logical Drive Message.

Figure 4- 15: Logical Drive information

Logical Drive Status: This sub-window displays information on configured arrays (logical drives) showing a unique array ID, RAID level, capacity, array status and a name that can be manually assigned.

Front View: This sub-window helps users to quickly identify configured arrays by the physical locations of its members. Different arrays are distinguished by different colors.

When any of the member drives is selected by a mouse click, the rest of the members will be highlighted by bright blue lines, indicating they are members of the selected array.

Formation of logical partitions is displayed next to the front view window.

Logical Drive Message: Messages related to a selected array are automatically listed at the bottom of the screen.

5.5.5 Using the Logical Volume Information Window

The Logical Volume Information window provides the configuration of a configured volume. The Logical Volume window includes three sub-windows: Logical Volume Status, Member Logical Drive(s), and Related Information.

5.5.6 Using the Fibre Channel Status Window

The Fibre Channel Status window displays information of Fibre host channel ID, connection speed, host-side connection protocols (topology), link status, WWPN port name and WWNN node name, loop IDs, and Fibre Channel address. The corresponding icon turns gray and is disabled if RAIDWatch operates with a SCSI-host subsystem.

These information are useful when configuring a subsystem for a heterogeneous environment such as a storage network operating for multiple hosts and applications.

5.5.7 Using the System Information Window

The System Information window provides key information about the RAID subsystem and the RAID controller unit that powers the subsystem. Enclosure information includes the operating status of power supply, temperature sensors, and cooling fan units.

Controller information includes CPU, firmware/boot record version, serial number, CPU and board temperature, voltage, and status of the battery. This window has no configuration options.

5.5.8 Using the Statistics Window

Select the Statistics window in the configuration tree, and start calculating “Cache Dirty”

rate or “Disk Read/Write Performance” by clicking either or both of the check boxes.
