>From the IBM Ultrium Setup and Operators Guide "The IBM LTO Ultrium Data Cartridge includes a Linear Tape-Open Cartridge Memory (LTO-CM) chip, which contains information about the cartridge and the tape (such as the name of the manufacturer that created the tape), as well as statistical information about the cartridge's use. Whenever you unload a tape cartridge, the tape library writes any pertinent information to the cartridge memory."
Maybe the volser is in the chip. Orville L. Lantto Datatrend Technologies, Inc.

Looks sharp! Currently tuning the setup (disk, memory, network, TSM, etc). Environment: AIX 4.3.3 ML10, pSeries 660-6H1, TSM 4.2 (5.1 next week) to 4.2.2.12, SCSI attachment to host, 3584-L32 and 3584-D32 frames. Two questions about 3584 tapes -- 1. Is it normal for it to take 45 seconds to read/verify the label on the tape? The tape load itself is pretty quick, but takes forever-and-an-half to read/verify the label. 2. There's two label sources -- one is the barcode scanner, which works great and *very* quick, and it seems the other label source is on the tape somewhere. Where exactly on the tape is the label preserved, other than the volser bar code label? Is it in the LTO-CM area of the tape? Or is it on the first part of the tape, or something? I'm curious about this because the implications is that if I do destructive read-write tests with tapes involving overwrite, I might potentially overwrite the label, and have to relabel it? The documentation suggests that 'LABEL LIBVOL' for a 3584 would update label in the LTO-CM area of the tape cartridge, but it isn't real definite or clear on that point. -Dan
