Hello, we have strange problem, till now everything was working fine, there
where no problems with dial and answer calls.
Yesterday our system crashed and we notice strange behavior.
>From time to time we can receive call but it drops after few second or caller
>can't hear anything.
Asterisk CLI shows:
== Primary D-Channel on span 1 down
== Primary D-Channel on span 1 up
== Primary D-Channel on span 1 down
== Primary D-Channel on span 1 up
== Primary D-Channel on span 1 down
== Primary D-Channel on span 1 up
all the time.
Telecom told us that problem is in our box.

We noticed that one of our RAID-1 disc is damaged but we removed it from disc
array (software).
What can I do? What can I check?
