How to remove disconnected arrays from Volume Manager's vxdmpadm listenclosure command output

Resolution

Following the removal of a previous array, the enclosures are still listed in Volume Manager's vxdmpadm command output:

# vxdmpadm listenclosure all
ENCLR_NAME        ENCLR_TYPE     ENCLR_SNO            STATUS       ARRAY_TYPE
============================================================================
EMC_CLARiiON0     EMC_CLARiiON   APM00064805699       DISCONNECTED CLR-A/PF
EMC_CLARiiON1     EMC_CLARiiON   APM00064800712       CONNECTED    CLR-A/PF
Disk              Disk           DISKS                CONNECTED    Disk

The EMC_CLARiiON0 enclosure is disconnected and confirmed as no longer attached to the system.

This enclosure can be removed using the following procedure:

1. Remove the persistent array data file:
 
# rm /etc/vx/array.info

2. Restart vxconfigd:

For systems running VERITAS Volume Manager in a non-cluster environment
 
# /sbin/vxconfigd -k

For systems running VERITAS Volume Manager in a VERITAS Cluster Server environment
 
a. Freeze all the service groups running on the system that has Volume Manager resources:
   #  hagrp  -freeze  

b. Restart vxconfigd:
  #  /sbin/vxconfigd -k

c. Unfreeze the service groups:
  #  hagrp  -unfreeze

For systems running Cluster Volume Manager
 
a. Stop the cluster on the local node:
   #  hastop -local

b. Restart vxconfigd:
  #  /sbin/vxconfigd -k

c. Start the cluster on local node
  #  hastart
 
This will force Volume Manager to regenerate the array.info file using only current system information.  Note that array names/numbering may change:

# vxdmpadm listenclosure all
ENCLR_NAME        ENCLR_TYPE     ENCLR_SNO            STATUS       ARRAY_TYPE
============================================================================
EMC_CLARiiON0     EMC_CLARiiON   APM00064800712       CONNECTED    CLR-A/PF
Disk              Disk           DISKS                CONNECTED    Disk
