Hi!

I'm trying to use amanda with HP Storageworks MSI5030 library.

It uses C7971A tpaes (100GB/200GB), but I can't find any amanda
tapetypes in th Net.  So, I ran amtapetype.  It was working for
about 12 hours with the folloeing results:

$ /usr/sbin/amtapetype -f /dev/nst0 -t "HP-C7971A"
Writing 1024 Mbyte   compresseable data:  26 sec
Writing 1024 Mbyte uncompresseable data:  71 sec
WARNING: Tape drive has hardware compression enabled
Estimated time to write 2 * 1024 Mbyte: 142 sec = 0 h 2 min
wrote 3174843 32Kb blocks in 9709 files in 46846 seconds (short write)
wrote 847763 32Kb blocks in 5201 files in 20794 seconds (short write)
define tapetype HP-C7971A {
    comment "just produced by tapetype prog (hardware compression on)"
    length 1107 gbytes
    filemark 74466560 kbytes
    speed 1736 kps
}
amtapetype: could not rewind /dev/nst0: Input/output error

I think length and filemark are too large for this tapes.  Does
anybody uses same tapes with amanda?

P.S. Right now I figured how to turn HW compression off (with mt
utility) and started amtapetype again...
