The relationship between the DVFTSStatus application and the physical hardware in the Stratus ftServer relies on the storage location and slot enumerations used in that ftServer model. The representation of the location of the hardware differs between ftServer versions and operating system tools.
To determine the relationship between the physical hardware location and the enumerated label, you must understand how the Stratus ftServer divides the hardware. This varies based on the ftServer model, however, they follow the same basic principle.
Stratus ftServer uses Storage Enclosures and I/O Enclosures to group hardware and slots within an enclosure to reference a specific device. Each enclosure is assigned a number and each slot in an enclosure is assigned a number.
Additionally, the device (such as a hard disk or a PCI network card) has a logical device number. The logical number does not necessarily refer to the physical location (slot number) of the device. For example, PCI Adapters start their logical numbering at 0. However, the physical location is numbered from 1 (as labeled on the 3210 model).
The ftServer Console, Veritas, and DVFTSStatus applications all report the devices using Enclosure/Slot/Device numbering. Therefore, Disk 0 in I/O Enclosure 10, Slot 3 is shown as Disk 10/3/0. However, since there are differences between these applications and the operating systems they run on, as well as the hardware itself (ftServer model, if rack-mounted or pedestal, numbering for PCI adapters versus hard disks), determining how the physical numbering starts varies. That is, the devices can be numbered from right to left, top to bottom, and so on.
Always refer to the ftServer documentation as well as the server applications help for specific information about mapping to a physical location. The fastest way to find the information you are looking for is to select the device, right-click, and then select Help.
The Stratus ftServer also has reserved slots (numbers) for devices that are embedded. Refer to the Stratus ftServer model’s documentation for more information. These reserved slots can be in the middle of your devices’ physical numbering.
If you disable a network card, the card does not show up in the DVFTSStatus application.
If you add a SCSI hard drive after booting, the logical number is assigned but can change on reboot. Conversely, removing a hard drive does not renumber the existing hard disks. This occurs because the logical numbering of hard disks is performed at boot up.
