Enabling  DMP debug logging

1.) Disable dmp_fast_recovery (on each node)
# vxdmpadm settune dmp_fast_recovery=off
 
2.) Increase dmp_debug_level to 6 (on each node)
# vxdmpadm settune dmp_log_level=9
 
3.) Increase vxconfigd logging to 9
# vxdctl debug 9 /var/tmp/vxconfigd.log

The cvm service group comes online on first node and the shared diskgroup gets import but it looks like the SCSI3 PGR registration receives error on one or both the paths. This causes DMP to disable one or both the paths. After enabling DMP debug logging, the messages logged to messages logs shows that DMP receives failure from the OS/HBA – EIO (5) error. This error seems to be returned by HBA Driver/OS and not from the Array. Error Message
