<div>On a DSS-G you can hop onto one of the servers and do</div>
<div> </div>
<div>lsscsi | grep disk | grep -v RAID | awk 'END {print NR/2}'</div>
<div> </div>
<div>The number should be the number of disks that you have including the log tip drives. If it's not then there is a path issue. I would imagine it's the same on the ESS.</div>
<div> </div>
<div>If I thought about it for a bit you could ditch the two greps and do it all in Awk. If the Awk is too complicated just replace it with 'wc -l' </div>
<div>but you will end up with a number that should be twice the number of drives.</div>
