WARNING
When the identify LED of Hub is off, the identity is disabled. When solid on, the
identity is enabled. The "RQST IDENT" for Enclosure is defined in the bit7, byte1 of the
"Enclosure control element" in the SES specification. Set the bit to enable the identity.
Clear the bit to disable the identity. We use the software package "sg3_utils" on Linux
for example, and have a SAS HBA and a cable to connect your host with the expander.
(A) Show the device for AIC Expander Controller (canister)

$ sg_ses --descriptor=EnclosureElement01 --set=1:7:1 /dev/sg2
(C) Disable the identity
