Method for resolving a cable mismatch in a target device

摘要

A method for method for resolving a cable mismatch by a target device is provided. The method includes determining that all PHYs in a receptacle are currently inactive, a PHY in the receptacle became active, and determining if there is a mismatch between a cable type and a stored cable configuration. If there is a mismatch between the cable type and the stored cable configuration, the method further includes disabling all other PHY groups in the receptacle that do not include the PHY that became active and notifying a user that a cable mismatch corresponding to the receptacle has occurred. If there is not a mismatch between the cable type and the stored cable configuration, then the method includes re-enabling PHYs in the receptacle, if any PHYs are disabled, and notifying a user that a cable mismatch corresponding to the receptacle has been corrected.

1. A method for resolving a cable mismatch by a target device, comprising:
determining, by the target device, that all PHYs in a cable receptacle are currently inactive, wherein the cable receptacle is configured to accept a cable that connects the target device with one or more initiator devices; determining, by the target device, that a PHY in the cable receptacle became active, wherein a PHY becomes active comprises a cable is plugged into the cable receptacle and a non-disabled initiator device is plugged into the cable; determining, by the target device, if there is a mismatch between a cable type and a stored cable configuration, wherein the cable type is stored in a first memory device of a cable plugged into the cable receptacle, wherein the stored cable configuration is stored in a second memory device in the target device; and if there is a mismatch between the cable type and the stored cable configuration, then:
disabling, by the target device, all other PHY groups in the cable receptacle that do not include the PHY that became active; andnotifying, by the target device, a user that a cable mismatch corresponding to the cable receptacle has occurred; if there is not a mismatch between the cable type and the stored cable configuration, then:
re-enabling, by the target device, PHYs in the cable receptacle, if any PHYs are disabled; andnotifying, by the target device, a user that a cable mismatch corresponding to the cable receptacle has been corrected.
