Openvms and MSA1000 failover

[Gian Luigi De Lorenzo_1]

I have just installed an openvms cluster with two alphaserver ds25 each one with two HBA that access the storage via FC switch, storage is composed by a MSA1000 with two controller one active the other in standby, in normal condition all works fine! but I wanted to check MSA100 controller failover i simulated a failure unplugging one of the fiber end also disconnecting the active controller but it never swtched to the other controller .. why? I know that on other os platform (like windows or unix) there is a a specific software "Secure Path" to do that, what on OpenVMS?

The multipath feature is embedded in OpenVMS, so no need for Secure Path. Did you make sure the connections on the MSA1000 have been set to the "OpenVMS" profile? Do you see the expected number of links in:
$ show device /multipath

?

thanks Uwe, for the answer: knowing that OpenVMS has embedded multipath feature I focused on MSA1000 setup and found I missed to setup all the "connections" with the command
add connection 'name' wwpn=xxx-yyy profile=OpenVMS
having done that all works fine

I have done on MSA1000

CLI>show connections
....
....
CLI>add connection "name" wwpn=xxx-yyy profile=OpenVMS

(for each connection showed)
