Manually removing existing keys from SCSI-3 disks
Review the following procedure to remove specific registration and reservation keys created by another node from a disk.
If you want to clear all the pre-existing keys, use the vxfenclearpre utility.
To remove the registration and reservation keys from disk
Create a file to contain the access names of the disks:
# vi /tmp/disklist
Read the existing keys:
# vxfenadm -s all -f /tmp/disklist
The output from this command displays the key:
Device Name: /dev/rdsk/c1t0d11s2
Total Number Of Keys: 1
[Numeric Format]: 86,70,66,69,65,68,48,50
[Character Format]: VFBEAD02
[Node Format]: Cluster ID: 48813 Node ID: 2
Node Name: unknown
If you know on which node the key (say A1) was created, log in to that node and enter the following command:
# vxfenadm -x -kA1 -f /tmp/disklist
The key A1 is removed.
If you do not know on which node the key was created, follow 5 through 7 to remove the key.
Register a second key "A2" temporarily with the disk:
# vxfenadm -m -k A2 -f /tmp/disklist
Registration completed for disk path /dev/rdsk/c1t0d11s2
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
Remove the temporary key registered in 5.
# vxfenadm -x -kA2 -f /tmp/disklist
Deleted the key : [A2------] from device /dev/rdsk/c1t0d11s2
No registration keys exist for the disk.
