Drive IDs

Hot-swap-drive ID locations are described in this section.

The hot-swap-drive ID that is assigned to each drive is printed on the front of the server. The following illustrations show the locations of the IDs of the drives. The ID numbers and the drive bay numbers are the same.

Note

• The drive bay IDs can vary, depending on the combination of the SAS/SATA backplanes installed in the server.
• When upgrading drive backplane configurations, you must install all 1.8-inch solid-state drive backplanes to the right of all 2.5-inch hard disk drive or 2.5-inch solid-state drive backplanes. All 2.5-inch drive backplanes must be installed to the left of all 1.8-inch drive backplanes.
• If you install a 8x1.8-inch drive backplane assembly, the drive IDs that are indicated on the server front bezel will no longer be valid. Use the drive ID labels that come with the backplane to renumber the drive IDs on the bezel.
• When you install a combination of 2.5-inch and 1.8-inch drive backplanes in the same server, the drive bay ID numbering is reset by skipping bay ID numbers based on the number of 2.5-inch drive backplanes that are installed to the left of the 1.8-inch drives backplanes.

  For example, if the server has a 4x2.5-inch drive backplane and a 8x1.8-inch backplane configuration, the drive bay IDs of the four drives in the 4x2.5-inch drive backplane are 0 through 3. The drive bay IDs of the eight drives in the 8x1.8-inch drive backplane start with an ID of 8 through 15. Since the drive bay IDs of the drives in the 4x2.5-inch backplane are 0 through 3, the IDs reset and skip four ID numbers (because the first backplane supports four drives). The drive IDs in the 8x1.8-inch drive backplane start with an ID of 8 through 15.

  If a 8x2.5-inch drive backplane had been installed, instead of the 4x2.5-inch drive backplane, the IDs are reset and skip eight ID numbers. The drive IDs of the drives in the 8x1.8-inch drive backplane would start at 16 through 23. See the following example illustrations and the illustrations in Supported SAS/SATA drive backplane configurations for more information.

In the following illustration, the drive bay IDs are in sequential order because all of the drive backplanes are 2.5-inch drive backplanes.

In the following illustration, you have a combination of drive backplanes. This example shows a 2.5-inch drive backplane and a 1.8-inch drive backplane installed in the server. In this instance, the drive bay IDs will require a gap in the bay ID numbering between the drive IDs in the 2.5-inch and 1.8-inch drive backplanes.
