Arcserv Backup System - LTO4 Drives
I have a Overland NEO backup system using VTL with migration to tape. The VTL(REO Box) runs fine but the tape unit keeps giving me errors. The migration to tape occurs after the data is written to the VTL. The Physical library has 3 tape drives which are HP Ultrium LTO4. The OS is Windows Server 2003, SP2. I am using Arcserv R15. Every time I try to erase or format it gives me a "ILLEGAL COMMAND" error. It also marks the tape as Unreadable. I have replaced the some tapes with new tapes with the same result. I am using HP drivers currently. CA and Overland have not been much help. Any help would be GREATLY appreciated.

How about not trying to erase or format the tape? I think erase should be supported (as long as it isn't WORM of course) but format isn't a valid command for an LTO as far as I can tell.
If the "erase" and "format" in question, are done via the ARCserve Manager Device window then they should be fine since the Format just writes a valid ARCserve header on the tape. For erase there are two, Quick which just overwrites the head to make it appear as blank and Long which is a true SCSI erase which normally should not be done since it take hours.
