I have seen the following messages (see below) in /var/adm/syslog/syslog.log.
These messages come up once a while on all our HP-UX 11.31 Sep '07 servers.
They are connected to an EMC Clariion with ALUA enabled. I don't see any problems regarding the fibre channel connection to the storage system.
So far we haven't experienced any outages.
Do you have any idea what these warnings are about?
Regards,
Thomas

SolutionYou have transient connectivity issues (clearly). There is a good discussion of timeouts and I/O errors here:

Re: PV becomes unavailable a few minutes
I took me a while to figure it out.
You were right, we had some connection issues on an interlink. Now all is fine.
Thank you.

Re: PV becomes unavailable a few minutes
>the URL cannot access right now, please give me the document's name
Unfortunately due to the docs.hp.com fiasco and our general laziness of not including titles when we had a URL, unless JRF remembers the document's name, you will have to do google searches.
