Topic: SME server 8.1 esata Hdd. Problems after reboot

[attila]

Hi all,

I have an issue with an eSata on SME server 8.1 an seeking for your advice.

I have recently bought an external HDD with USB3, eSATA and Firewire 800 connections It has external power supply which didn't seem to be an issue at first. Since USB3 is not supported I went for eSata. Connected it came up first time and I said yay it works like it should, but after a restart the problems started. First I had to tell the system not to add it to raid, but it is sorted, and looked ok till I have restarted it again. The disk has disappeared. After a while I have worked out that the system doesn't recognise it if it is there at boot. After every restart I have to power don and disconnect the drive and connect it again to make it visible which is a really bad sign as the server now 2000miles away from where I sit. I had to fall back to usb2 for now, but that is really slow for backups.

Is there any way to trigger the os to rescan the eSATA port .

WHat I tried but didn't work is :
 echo "scsi add-single-device 6 0 0 0" > /proc/scsi/scsi
 but that fails with slow or no response in messages.


when it connects I see this in the messages:

attila,


I don't have a good answer for you, but udev comes to mind...


So I googled "udev external USB drive" and this came up:
