Controller SAS address attributes

Interpret the results of viewing the controller SAS addresses.

After you perform the procedure described in Viewing controller SAS addresses, information similar to the following is displayed:

+--------------------------------------------------------------------------------+

The SAS address is displayed for each adapter port as if each SAS port were a narrow port (in other words, the port consists of a single phy). Each SAS cable contains four phys that are typically organized into either a single 4x SAS wide port or two 2x SAS wide ports.

When using cables that create wide ports, the SAS address for the wide port will be the SAS address of the lowest-numbered adapter port in the wide port. For example, if the controller depicted in the preceding screen is connected with a 4x cable such as the AE cable, the SAS address of the controller on that wide port would be either 5005076c07447c01 or 5005076c07447c05, depending on which connector is used.

Note: Any single phy in a wide port can fail and might not be included as part of the wide port if the adapter is reset. This can result in the controller reporting a different SAS address from what was previously reported.

For example, a 4x wide port that contains ports 0 through 3 could respond to any of the SAS addresses listed for the adapter port, depending on which phys failed. Therefore, all addresses in the wide port are considered as possible controller addresses when managing access control using SAS zoning.
