Hi Fernando,

Sorry to you as well for the late reply!

Well, it is quite possible that there is some kind of connectivity
problem on the SAN and the network switch.  Access to it is slow, even
though the vendor had looked at it during a troubleshoot session not
long again and didn't find anything (I appreciate that the warranty
covers this and not just hardware issues; though they didn't look too
carefully).

But, this aside, the file system also does have a problem...  I mean,
connectivity between a server and the SAN was cut during a write
operation...  I'm 100% sure of that and couldn't stop it from
happening.

So, I think I might have two problems on my hands.  I'll look at the
switch's VLAN settings again -- thank you!
