Refreshing lost keys on coordinator disks
If the coordinator disks lose the keys that are registered, the cluster might panic
when a network partition occurs.
You can use the vxfenswap utility to replace the coordinator disks with the same
disks. The vxfenswap utility registers the missing keys during the disk
replacement.
To refresh lost keys on coordinator disks
1
Make sure system-to-system communication is functioning properly.
2
Make sure that the cluster is online.
# vxfenadm -d
