Removing existing keys from disks

Use this procedure to remove existing registration and keys created by another node from a disk.

 To remove the registration and reservation keys from disk

1. Create a file to contain the access names of the disks:

   # vi /tmp/disklist

   For example:

   /dev/rdsk/c0t0d0s2

2. Read the existing keys:

   # vxfenadm -g all -f /tmp/disklist

   The output from this command displays the key:

   Device Name: /dev/rdsk/c0t0d0s2

   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:

   # vxfenadm -x -kA1 -f /tmp/disklist

   The key is removed.

   If you do not know on which node the key was created, follow step 4 through step 6 to remove the key.

4. Register a second key "A2" temporarily with the disk:

   # vxfenadm -m -kA2 -f /tmp/disklist

   Registration completed for disk path /dev/sdh

5. Remove the first key from the disk by pre-empting it with the second key:

   # vxfenadm -p -kA2 -f /tmp/disklist -vA1

   key: A2------ prempted the key: A1------ on disk

   /dev/sdh

6. Remove the temporary key assigned in step 4.

   # vxfenadm -x -kA2 -f /tmp/disklist

   Deleted the key : [A2------] from device /dev/sdk

   No registration keys exist for the disk.

7. Verify that the keys were properly cleaned:

   # vxfenadm -g all -f /tmp/diskslist
