Hello, it is trying to delete the keys on the Fencing Disk Group. The following disks are used for I/O fencing disk group.

I want to reclaim the disk below. Need to know how to remove the reservation key before reclaiming the LUN's from the storage level.

Simple point here, you are trying to clear the keys from coordinator disks,

A simple answer to that, if you shutdown fencing ofcourse after shutting down VCS completely ... once the fencing is down & module is unloaded, it should automatically clear the keys from fencing disks..

 

# hastop -all

# /etc/init.d/vxfen stop

# modunnload -i <mod_id_for_vxfen>    (check module ID with modinfo command)

post above steps, keys should be cleaned.

 

If it were data disks, I would go with procedure mentioned by Jubin ..
