Hi, We have a Storagetek L80 tape library with 4 LTO drives. We've been seeing a lot of SCSI problems on the host. Host is a storage node running RedHat Linux. I end up rebooting this host about once

How do we determine if the arm has the highest priority? How do we give it the highest priority? We had it daisy chained to drives 1 and 2 which were using channel A on the Adaptec dual channel card

Hi George According to http://www.pcguide.com/ref/hdd/if/scsi/confIDs-c.html, the SCSI device priority order is (highest to lowest) 7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8. 7 is usually

George, I previously ran an L80 on Solaris where I definitely saw problems having the robot arm and a drive share the bus; in fact, StorageTek specifically recommends against that. Once I added an ad

Byron, The -D3 option sounds useful. I do not see this option in the man pages, though. How do I tell NetWorker to run nsrmmd with this option when it starts up? I took a look at /usr/src/linux-2.4/i
