HANFS, 2 9334's, secondary server has stale file handles.

Question:

Customer has HANFS running at AIX 3.2.4 on RISC System/6000 Model 370s.

There are two 9334's, each with two 1GB disks.

When the primary server is used everything works fine.  
When the secondary server takes over the file handles are stale. 
When the primary server comes back in use, the file handles are not stale.

Response:

The major numbers for the shared volume group didn't match. These numbers
need to be the same on both the primary and the backup HANFS server. This
can be checked with the command:

 "ls -al /dev/name_of_shared_vg":

crw-rw----   1 root  system    40,  0 Oct 21 17:14 /dev/name_of_shared_vg

In this example, "40" is the major number.

When these numbers do not match between the servers, do the following:

- Bring HANFS to a dormant state on both systems:
   stopsrc -g hanfs

- Export the shared volume group from the backup system:
   exportvg name_of_shared_vg

- Check the major number assigned to the shared volume group on the 
  primary server:
   ls -al /dev/name_of_shared_vg

- Import the shared volume group on the backup system (set the major 
  number):

   importvg -y name_of_shared_vg -V'common_major_number' hdisk\#

- Varyon the shared volume group on the backup system:
   varyonvg name_of_shared_vg

- Change the characteristics of the shared volume group so it is not 
  varied on automatically at boot time:
   chvg -a n name_of_shared_vg

- Varyoff the shared volume group on the backup system:
   varyoffvg name_of_shared_vg

- Start the HANFS software (on Both systems):
   startsrc -g hanfs
