FC-60 Controller

[harry_7]

Hi,

I have 2 N Class servers with cluster environment with share storage SC-10 device's. Every thing was fine. So accidently on the same day we removed the cluster and forgot to removing the cabling from the cluster environment. So after the machine rebooting we found one of the FC-60 controller faulty.

Can some one tell me now how to replace the Controller. Controller replacement is not a big job. But how I can recover the data from the exeisting disk's.

In normal condition if it gose bad all the file system will move to other machine.

Regards

If you have lost the VG information from one side of the cluster then recover it by running :

vgexport -s -p -m -v .mymap /dev/

on the machine that can still see the disks.

Copy this file across to the other machine, and then :

vgimport -v -s -m /tmp/.mymap /dev/

This will reinstate the VG information.

If I understand correctly, the only problem is that you have a faulty Fibre controller on your FC60. Unless you have changed anything on your N class servers, you should just be able to swap the controller. All the data and LUN information should still be the same as before your problem and both N class servers should still be able to see the data in the same way.
