SFCFS 5.0 MP3RP5, AIX 5.3, storage is HP XP20K. This issue will happen in every platform.
The storage is HP XP20K, customer 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 setting detail meaning is in 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 need verify the vxfence register key.
Change host mode option to 02 in storage array XP20K lun mapping .
