Alternate disk link failure

Carlos_8 — Mon, 29 Jan 2001 23:33:05 GMT

We have a n-class box connected to a Emc array via fibre cards. I am getting alternate disk link failures on multiple disks. I am new to this particular environment so this question will probably be pretty simple. I need to know how I can check that my path from my server to my EMC box is good. I have heard of the 'inq' function of EMC but need more info on it.

You can check if the link is up with the following command."fcmsutil "devicefile""The device file is normally "/dev/fcms "or "/dev/td "follow by a number with the option "stat" you can see the Register alos Error register of the interface.
The manpage of the command held some additonal infos.

Thanks Frank,

We actually found then problem to be a " sorry " by one of our other buildings. They made some config changes and forgot to disable the links. I will keep the info you gave me because it would help narrow the problem faster in the future. Thanks again!!!!
