I have 5 Media servers connected with SSO to 10 LTO Gen II's and one
server is constantly reporting 84's on
it's backups. I've found that Netbackup is very particular and will
start freaking out over nothing..

<div>
<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">I’d like to get some feed
back as to everyone’s
experience concerning Media write errors. I have 4 sites that are
almost
identical, Compaq servers, Compaq HBA’s, STK L700’s and SDLT320
drives. The only difference between these sites would be number of
processors
in the server, amount of memory in the server and the number of SDLT
drives. One
site in particular has racked up over 182 frozen tapes since I
implemented the
backup solution which is only 22 months old. </span></font><o:p></o:p></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span

<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">First question, does 182
frozen media in only 22 months seem
to be a high rate? Media is always brand new and either <st1:City
w:st="on"><st1:place w:st="on">Fuji</st1:place></st1:City> or
Quantum.</span></font><o:p></o:p></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span

<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">STK has been working with
us to try to resolve this issue
and actually gave us 120 brand new tapes last week. We pulled out all
of our
existing tapes and loaded up the 120 new ones. Over the weekend we had
3
CRC’s media write errors. The percentage seems kind of high.

<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">Is this a normal level
for CRC’s with SDLT? </span></font><o:p></o:p></p>

<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">We are actually at the
point of considering changing
technology to LTO drives and media. We have another small site due for
replacement and so far that seems to be the road we are taking because
of the
SDLT CRC issue. </span></font><o:p></o:p></p>
