  • 1.  LTO Drive Unavailable

    Posted Wed July 27, 2016 07:19 AM

    Hello Experts

    What a relief that I found that community. I hope you will be able to advise me as TSM is totally not my area of expertise and I've just inherited TSM 6.1.7 server to manage with VLT on EMC DataDamain.

    When i run q drive command I see some drives unavailable, how should I investigate it ? Could you provide step by step procedure or any ideas what could be the reason that some vtl drives are anavailabe and others from the same DataDomain ore online ? From DataDomain site i do not see anything suspicious in the logs.
    If you have any clues please take into account i'm not an expert and i just started to manage TSM

    Thank you

    Thanks ! After that command it's all On-Line now as you can see below.

    One drive has Device Type  UKNOWN, i'm not sure if it has any impact at all ?

    Do you kave any suspicions what could be the root cause that those drives went off line ?

    Where could I find any logs to review as I need to provide some kind of explanation and assess if we can expect any further issues.
