tape drive status
We have upgraded the two machines in JWG206 used for reading tapes.
The newer taurus host now has the windoow seat in 206 where gryphon used to live.
Taurus has the LTO-1(Ultrium 1), 8 mm, and 4 mm tape drives attached. These drives are currently turned off.
To use the tape drives you must:
i) turn on the tape drives ii) reboot tarus
Please turn off the tape drives on taurus when finished.
Taurus also has a dvd burner attached. Use the linux program "k3b" to burn cd & dvd discs.
The new gryphon machine is the large Dell Poweredge 1900 with lcd monitor.
Gryphon also has a copy of (64bit) mathematica installed locally.
Gyrphon has the LTO-3/Ultrium 3 tape drive. You cannot reliably write files to a LTO1 or LTO3 tape over the network.
To write files to a tape LTO3, you must first transfer your data to the hard disk space locally on gryphon. The local tape "queueing" directory is /data/gryphon, which you can access from your workstation.
Further, DO NOT USE TAR TO WRITE FILES ON THE LTO-3.
Standard UNIX commands tar/cpio and dd cannot reliably write files to an LTO3 tape.
Use the unix command "star" instead of tar to write files to a LTO3 tape. The recommended command-line for "star" star -c b=256 -fifo fs=256 f=/dev/nst0 file/dir_name.
More information about "star" command can be found at: http://cdrecord.berlios.de/old/private/star.html
