The storage node is on Win2K, but there is an 'mt' program in c:\Program
files\nsr\bin, the output of status command is below. The default
block size is showing as 64k, but on Legato device GUI, it is set for
128k. I'm not sure how to show the equivalent info for the SGI
server--there's no included Legato 'mt', just the usual Unix command and
it doesn't show this info. It seems to be set to use variable block
size (Media Blocksize = 0 ??), or at least it can support it; and I am
not sure why the correct block size wouldn't be detected, so I don't
know if this is the real problem or not.
I'm using the local 'nsrjb' to try and load the tape again, the GUI
shows 'Verifying label, moving backward 2 file(s)" next to the device in
the top Devices monitor panel, and "<datestamp>rd=dcsrv05:\\.\\Tape0
Verify label operation in progress" in the Messages panel, and this is
where it hangs forever.
FYI I did 'mt stat' on both drives, one with the problem tape and one
with a tape that works fine, same results for both.
C:\>mt -f \\.\Tape0 stat
\\.\Tape0:
Media Capacity = 101.16GByte

What make test on SCSI bus ?. In directory /etc/LGTOuscsi you search the
basic commands for test devices. Example: tur, inquire...
If you verify size of block, you must load tape to drive and run command
mt, example: mt -f /dev/rmt/0cb status. I don ´t know what devices you have
make there, therefore I show it like /dev/rmt/0cbn. You will show correctly
adrress inside networker admin (nwadmin).
Atention, if you set fixed block size you must specify it. Example, insert
NSR_DEV_BLOCK_SIZE for your device to scriptfile networker. Restart it. I
recommended use variable size (=0) - you confirm it with command mt. If you
change size of block now, you cannot restore your data.
