Autopath errors

[Elton Agolli]

We have an HP-UX 11.11 system connected to an external storage EVA-4000 through fiber channel.
We are having problems connecting to volume groups in the storage.
When we issue the "vgchange -a y vgxxx" command nothing happens but some errors in the syslog.
The logs are something like:
"AUTOPATH error : Path 0xbcxxxxx failed!Rerouting to alternate."

Do we have to do with an hardware problem in the xternal storage or some other problems could be also possible?

Once the path has been returned to normal, autopath will automaticall rebalance.
