Removing Existing Keys From Disks

To remove the registration and reservation keys created by another node from a disk:

1. Create a file to contain the access names of the disks:
     # vi /tmp/disklist

   For example:

   
     /dev/rdsk/c1t0d11s2
2. Read the existing keys:
     # vxfenadm -g all -f /tmp/disklist

   The output from this command displays the key:

   
     Device Name: /dev/rdsk/c1t0d11s2
     Total Number Of Keys: 1
     key[0]:
        Key Value [Numeric Format]:   65,49,45,45,45,45,45,45
        Key Value [Character Format]: A1------
3. If you know on which node the key was created, log in to that node and enter the following command:
     # vxfenadm -x -kA1 -f /tmp/disklist

   The key is removed.

4. If you do not know on which node the key was created, follow step 5 through step 7 to remove the key.
5. Register a second key "A2" temporarily with the disk:
     # vxfenadm -m -kA2 -f /tmp/disklist
     Registration completed for disk path /dev/rdsk/c1t0d11s2
6. Remove the first key from the disk by preempting it with the second key:
     # vxfenadm -p -kA2 -f /tmp/disklist -vA1
     key: A2------ prempted the key: A1------ on disk  
     /dev/rdsk/c1t0d11s2
7. Remove the temporary key assigned in step 5.
     # vxfenadm -x -kA2 -f /tmp/disklist
     Deleted the key : [A2------] from device /dev/rdsk/c1t0d11s2

   No registration keys exist for the disk.
