Hi,

PHY is not the Physical Disk, even if it sounds so.

Explanation from "HPE MSA 1060/2060/2062 CLI Reference Guide":

PHY
One of two hardware components that form a physical link between devices in a SAS network that enables transmission of data.

This Message is the right one:

A PHY was disabled. (enclosure: 1, module (disabled path to this disk): A, drawer: 1, disk slot: 24, reason: )

Thanks, Cali.
I removed disks then put slot again to verify alert message secondary,
but no more display "A PHY was disabled. and A PHY was enabled.
What settings do I need to make "A PHY was disabled. and A PHY was enabled. appear again?

Don't take care of PHY Messages and don't change PHY Settings without direction from technical support.

Everything is fine, leave it as it is.
