The following vxdg adddisk command may fail when an inconsistency between what is in the kernel differs to the configuration details on disk.


# vxdg -g datadg adddisk datadg05=emc0_00ea
VxVM vxdg ERROR V-5-1-10128  Configuration daemon error 441
 

As the message indicates a possible mismatch between the Veritas kernel and the configuration on disk, the disk assignment will fail until corrected.

 

 

In most situations a flush of the diskgroup configuration from the kernel back to disk can resolve the issue:

 

Note: If Veritas Cluster Server is installed and operational, it is advisable to freeze the corresponding VCS Service Group for the impacted diskgroup.

 

The "vxdg flush" operation rewrites all the on-disk  structures (disk  headers, configuration copies, and kernel log copies) managed by VxVM for the specified disk group.

Also,  if  any  configuration  copies are disabled (for example, due to I/O failures), this command rewrites those configuration copies, and attempts to enable them.
If no diskgroup name is specified, then all diskgroups structures are updated.

In a CVM environment, the flush command must be run from the CVM master node.  If the command is run from any CVM slave node, the command silently ignores shared disk groups.


Downtime Required:

If the "vxdg flush" operation is not successful then a reboot of the server, or a deport and import of the impacted disk group may be required.
