Hi Richard, There is only one device class configured on this TSM Server....
Device Class Name: LTOCLASS1 Device Access Strategy: Sequential Storage Pool Count: 4 Device Type: LTO Format: ULTRIUM3C Est/Max Capacity (MB): Mount Limit: DRIVES Mount Wait (min): 60 Mount Retention (min): 60 Label Prefix: ADSM Drive Letter: Library: LTOLIB1 Directory: Server Name: Retry Period: Retry Interval: Twosided: Shared: High-level Address: Minimum Capacity: WORM: No Drive Encryption: Allow Scaled Capacity: Last Update by (administrator): ADMIN Last Update Date/Time: 01/06/2009 08:52:42 The Technote you mentioned....I guess it doesn´t help me as it is about a Virtual Library.....this is a IBM TS3100 Library...the Management Console shows the following information: LIBRARY IBM 3573-TL DRIVE LTO ULT3580-TD3 Also...about this volser mode...how do I check if it is 6 or 8...and how do I change it, if needed? Thanks Mario ________________________________ From: Richard Sims <r...@bu.edu> To: ADSM-L@VM.MARIST.EDU Sent: Thu, February 25, 2010 9:32:29 AM Subject: Re: ANR9999D error mounting tape We don't have the context on whether this has been working for you and then stopped working, or whether you are trying something new, or whether this is a problem with other types of operations on tape in that library, or may be isolated to specific cartridges in that library. I'd start by checking the device class assigned to your TSM db backups, and assure that the drive type is consistent with the "L3" tape at issue. You can take a look at Technote 1303094 to see if that pertains. We don't know your library type, but possibly it is configured such that it's operating in a 6-char volser mode rather than 8, so the L3 is not being conveyed to TSM for media type to be known.
