i execute the following command:
cmgetconf -c S2500 S2500.config
so, this message appear at the end

Error: Volume group /dev/vgtsmdb is configured differently on node s2500c than on node s2500d
Error: Volume group /dev/vgtsmdb is configured differently on node s2500d than on node s2500c
Error: Volume group /dev/vgtsmstg is configured differently on node s2500c than on node s2500d

Error: Volume group /dev/vgdesarrollo is configured differently on node s2500c than on node s2500d

Looks to me that some volume group work was done without exporting you map files to the failover node.

Remember to always vgexport your volumegroup and vgimport to the it to the failover node whenever LVM work is done on a SG cluster.

vgexport -p -s -m /tmp/mapfile /dev/vgtsmdb
rcp /tmp/vgtssmdb.mapfile othernode:/tmp
vgimport -s /tmp/vgtssmdb.mapfile /dev/vgtsmdb

What type of disk array are you using? Try doing an ioscan on both systems to verify that all the drives in the volume groups are pathed to both machines.

Hi:

The Technical Knowledge Base (document #UMCSGKBRC00007671) notes that this problem arises whan a one node has a different number of IO adapters to a shared disk than another node does. Interestingly, the TKB report discusses this as a warning and not as an error. Still, I would suggest that you verify the the numbers of adapters (e.g. by comparing the contents of /etc/lvmtab for the common dis, on all nodes), and if different, attempt to equalize them to see if the problem resolves itself.

Regards!
