CFS cannot mount as vxfence key register issue when host mode option do not set correctly in storage array side

Problem

       Two node SFCFS with CFSMount type file system resource. A CFS file system can mount after two node reboot. 

      The CFSMount resource can not be online,. The filesystem cannot mount after one node stops HAD with " hastop -local" command and then starts HAD with the command "hastart". This issue happens in every node.  But CFS filesystem can mount on every node when on SFCFS only on one node.

Cause

The storage is HP XP20K. Customers set the host mode option 22 in this SFCFS environment . Check Veritas Storage Foundation Products by Symantec Host and Storage Configuration Guide for DMP. The mode meaning is below :

02 (Veritas Storage Foundation for Oracle RAC),
22 (Veritas Cluster Server)

So the correct setting should be 02. Incorrect setting lead vxfence module work unexpectly,  the cluster file system cannot mount as it needs to verify the vxfence register key.

Solution

Change host mode option to 02 in storage array XP20K lun mapping .

Applies To
