I have an FAS2020 active-active with a failed PSU. After the replacement of PSU2, I keep receiving this warning: 'there do not appear to be any disks attached to the system. No root volume found.' and it keeps rebooting itself. At a closer look I've managed to figure that the state of the SAS adapter 0c is down. It currently has 3 PHY States:
3 3.0 Gb/s
On the other controller, the PHY states of the SAS adapter are all UP with 3.0 Gb/s state. All disks are now connected to the first controller (takeover). How can I change the state of the 0 to 2 PHY from disabled to 3.0Gb/s?
