I deleted the device path by running the command:
echo 1 > /sys/block/sda/device/delete on Redhat Linux. Since it was the only path, I no longer have connectivity to that machine. I am able to
ping it, not able to
ssh to it.
How can I add the device path back? I found a link on how to add a new path. But I am not sure how to run those commands since I have no access to the machine. Do I have to physically reboot it?
