There are are something wrong going on here with the storage - it is
reporting SCSI errors for one of the channel. And as I figure out, there
are some possibilities that I may have to end up with reformatting the
disk array. At the moment it's okay but not sure for how long. So, I
strongly suggest, all the users should back up their data somewhere else
ASAP before it goes completely off-line.
I'm very sorry for the inconvenience this may caused.
