logprn about va7400, and users said the response time was slow.

[stephen peng]

dear all,
i get following messages for logprn of a va7400, and it repeats every 4 or 5 minutes, and users said that the response time of some regular command, like bdf, was a little bit slow. the fact was that one disk of one enclosure had been failed, was it the main cause of those messages' producing?
