Add Order Number of Drive Enclosures

The Add Order Number of a Drive Enclosure is the numeric value that corresponds with the order that the Drive Enclosure is installed or added to an Oracle FS System. Use the Add Order Number to look up the string number and location of a Drive Enclosure within the string.

When adding Drive Enclosures to a system, the first Drive Enclosure to be added has an Add Order Number equal to the number of existing Drive Enclosures in the system plus one.

For example, if a system has six Drive Enclosures installed, then the next Drive Enclosure to be added is Add Order Number 7. If the system follows the factory configuration, the chassis ID numbers of the existing Drive Enclosures are 01-06, and the newly added Drive Enclosure is assigned chassis ID number 07.

Note: Depending on the history of the system configuration, the Add Order Numbers might not match the chassis IDs values of the Drive Enclosures in the system.

Note: The chassis IDs should reflect the cabling string order. You can use Oracle FS System Manager (GUI) or Oracle FS CLI (FSCLI) to modify the chassis IDs to reflect the cabling string order. Exercise caution when modifying chassis IDs to ensure that the modifications reflect the proper order.

The following table shows the Drive Enclosure Add Order Numbers for a system configured with one SAS HBAs per Controller.
