Hello,
it just happened that there was an unresponsive HDD in the system (a WD
RE3 1TB SATA drive).
Multiple reboots of the machine (not poweroffs) did not revive it, and
the server did not create a /dev device for it on subsequent reboots. So
I thought it had failed.
But when I tried removing and inserting it in another hot-swap slot it
started working again. After reinserting it in the original slot also it
was working.
Probably a poweroff of the server would also have revived it.
FWIW: smartctl -x tells no error is logged by the drive.
It could also have been a controller glitch maybe?
For a future time, I know there are SCSI reset messages which can be
sent to various things in the path to the drive. Could someone teach me
how to send a reset message to the controller card, to a slot and/or to
a drive, from bash?
Or any other suggestion for reviving a slot / drive which do not imply
powering off the machine?
Our controller is LSI 6201-16i. No SAS expanders. I am able to determine
the phy port number of the unresponsive drive.
Thanks for suggestions
J.
