Environment



 [ VERSION  OF OS/PACKAGE ]
- RHEL 5
- SFHA5.1


Cause



 

[ EXPLNATION ]
vxdisk scandisks error will occur for data protection, after adding new Luns to the system.
"data corruption possibility" is detected during device discovery when inconsistency is found, DMP aborts reconfiguration and logs the message.

Solution



 

[ WHAT NEED TO DO ]
1. If the systems are in clustered environment, then please freeze the system prior to refresh the VxVM config:
Before the maintenance:
#haconf -makerw
#hasys -freeze -persistent -sys <sysname>
#haconf dump

After the maintenance:
#haconf -makerw
#hasys -unfreeze -persistent -sys <sysname>
#haconf dump
  
2. Thereafter, Please use below procedure to recreate VxVM DMP devices:
a)
Update the OS device tree using OS tools
#
devfsadm -Cv   

b) Update VxVM config
#mv /etc/vx/array.info /etc/vx/array.info.old
#mv /etc/vx/disk.info /etc/vx/disk.info.old

Remove all the entries from the /dev/vx/dmp, and /dev/vx/rdmp directories except entires for bootdisk or bootmirror from the following directories.
#rm -rf /dev/vx/dmp/*
#rm -rf /dev/vx/rdmp/*
 
3) Rebuild the DMP device tree.
# vxconfigd -k
