VolumeMediaFormat upgrade for volume failed. Status 20888

Question

Hello All;
I have 2 x OES 11 SP2 with NCS servers with the latest updates. These servers are virtuialized on a SLES 11 SP3 with KVM
Following the Docs on putting DHCP on a NCS with NSS volumes
https://www.novell.com/documentation...a/bbe81cc.html
Installing and Configuring a Cluster 8.3.3
Step 9
9. To hardlink, enable the shared volume on which the dhcpd.conf and dhcpd.leases files are hosted eg.DHCPVOL.
Invoke nsscon in the linux terminal and execute the following commands:
/ZLSSUpgradeCurrentVolumeMediaFormat=VolName
/hardlinks=VolName
in doing the first command, I receive
nss /ZLSSUpgradeCurrentVolumeMediaFormat=VOL1
VolumeMediaFormat upgrade for volume "VOL1" failed. Status = 20888.
The second command states the first command must be done.
nss /hardlinks=Vol1
Hardlinks may not be created on volume "vol1" until it is upgraded using the "ZLSSUpgradeCurrentVolumeMediaFormat" command...
I can offline, online, migrate the pool (with a single volume) between the 2 servers with no issues.
I have checked the nss and ncs modules on the 2 SLES 11 SP3 servers and they are exactly the same.
using nsscon, I can see the _ADMIN and VOL1 volumes. The _ADMIN has the hardlink attribute. So why does VOl1 not upgrade the media format? And what must be done to make this command work?
I cannot continue until this step is fully completed.
Thank you.

>>> So why does VOl1 not upgrade the media format?
Because we believe there is still a node is not fully upgraded to OES11 SP2. Volume upgrade cannot proceed until all nodes are capable of understanding the new media format.
>>> And what must be done to make this command work?
1. Run "sbdutil -v" on one node to check SBD signatures of all nodes.
The signature for all slots should be
"SBD*"
If some of them have "SBD+" (or other signatures), that's the cause of the problem.
2. Make sure those nodes are really on OES11 SP2, or no longer a participant of the cluster.
3. Run command "sbdutil -i" on one of the nodes to update all signatures.
You can do all of the above while NCS is running. You can now try to upgrade the volume without restarting anything.
