IBM tape library TS-3100 get offline randomly once in a month
I am using backup exec 2010 R3 in windows server 2008 64 bit. with IBM tape library TS3100. My all scheduled backup jobs runs very fine but once in a month tape gets offline and we manually restart tape libraray . we also checked this issue from IBM no error found there.
rendersr - if your question
rendersr - if your question is to me, then yes I did - our switch zoning was incorrectly configured by the company that implemented it (this is way back in February). The part that had me stumped was that this did in fact work for a while back in march, but then stopped. Now that the zoning is fixed (in fact, we directly connected it instead), it works fine.
To reiterate - my issue was a FC zoning issue, correcting the zoning configuration fixed it.
