Hello

We have a problem with Netware Cluster Services 1.6.4 on four Netware 6 SP5
server.

Following happened:
We downed the Server who holds the Master_IP_Address, then the three other
nodes abended.

Server SN-CLS01D (Holder of the Master:IP_Address) manually downed

Server SN-CLS01A Abend with following Error:
Server SN-CLS01A halted Thursday, 27 April 2006 17.29.55,462
Abend 1 on P00: Server-5.60.05-0: VLL: VllInvokeCallbacks() called with
empty bitmasks


Server SN-CLS01B Abend with following Error:
Server SN-CLS01B halted Thursday, 27 April 2006 17.29.55,473
Abend 1 on P00: Server-5.60.05-0: VLL: VllInvokeCallbacks() called with
empty bitmasks


Server SN-CLS01C Abend with following Error:
Server SN-CLS01C halted Thursday, 27 April 2006 17.29.55,500
Abend 1 on P00: Server-5.60.05-0: VLL: VllInvokeCallbacks() called with
empty bitmasks


For your information:
From that day we couldnīt do any maintenance on these Servers because we
had no Maintenance window.

Today we have a Maintenance window again, and we testet to migrate the
Master_IP_Address the following way:
Cluster Leave on SN-CLS01D. No Server Abend, SN-CLS01C took
Master_IP_Address over.
Cluster Leave on SN-CLS01C. No Server Abend, SN-CLS01A took
Master_IP_Address over.

Even when we down the Server that is holding the Master_IP_Address the
Abend doesnīt occured.

The error is not seen anymore yet.

Because we donīt find anything about Abend listet above in the
Knowledgebase and the customer wants to have an explanation, I
post this Message. Hopefully someone kann help us or give us an hint what
this Abend meant and how we can prevent this Abend in the future.

King Regards
