Description

SNMP dies on QLogic SANbox2 FC switches

In a cluster with a QLogic SANbox2 FibreChannel switch, SNMP can die

periodically. When this occurs, servers cannot be fenced, and servers that have

already been fenced cannot unfence themselves.

To recover, go to Admin mode on the switch and then run the hotreset

command:

admin start

admin>

hotreset

The hotreset command resets the switch. (Before the switch is reset, all running

applications save their FibreChannel state. That information is then used by the

applications when the switch comes back up.)

If the

cluster does not recover on its own after the switch is reset, you may need to

reboot the affected servers or restart HP Clustered File System on them.

shadow copies. If you want to use the NT ba ckup software on a PSFS volume,
