Hi there.
Did you try the mt and mc command ?
For the params read the manpages.
By the way, did you try to switch it off and on again ?
Have you checked all cable connections ?

Hi Alexander

unfortunately the command mc and mt man page just describe the scsi release of tape device file but I will try

Yep I have ended up to :
- reboot robot
-reboot the fiber router
- reboot the switch
- but not the server (it is in a 24/7 environement)

Have you checked all cable connections ?

Is there a way to analyse the connection a part from mc (because all mc command are successful on the correct device file /dev/rac) ?

I forgot to mention that the device file mentioned in the syslog.log do not exist when running ioscan -fn

Thanks in advance

Re: how to scsi release SAN attached robot ?

the units i work with have a two different scsi-id's for the robot and the drive

maybe check the robot and the drive if the have the cdesired settings
on units with software setup instead of switches may be the setting are reset so they both use id "0" instead of "0" and "1".
