Hi,
I currently have a cluster where I can relocate a disk service manually thru
asemgr, but cannot get the service to failover automatically when one of the
servers is down. I tried the automatic failover by shutting down the server
(NodeA) while the service is still online in order to simulate a server
failure. A check on the daemon.log on the other server (NodeB) shows these
messages:
NodeB ASE: NodeB Agent Notice: Starting service PP1-sap
NodeB ASE: NodeB Agent Notice: didn't reserve device
NodeB ASE: NodeB Error: AM can't reserve device /dev/rz120g
NodeB ASE: NodeB Agent Warning: can't reserve /dev/rz120g
It seems to me that during a manual relocation, NodeA will release the
device so that NodeB can takeover. However, a shutdown on NodeA doesn't seem
to be able to release the device even if I tried to power off NodeA.
The disk service favored member list contains both NodeA and NodeB, so I
think the setup should be Ok.
Below are my environment:
NodeA - GS60, UNIX V4.0F, Trucluster V1.6
NodeB - ES40, UNIX V4.0F, Trucluster V1.6
Storage controller - KZPBA, with EMC Powerpath V1.5.0.6
Storage - EMC Symmetrix
Any advice or suggestion on how to troubleshoot this problem is greatly
appreciated.
Thanks in advance,
Carlos
