Re: [Networker] LTO tape drives on Linux
2008-09-04 13:08:58
I am using the QLogic drivers (on Red Hat EL/AS 4) downloaded from the
QLogic site that are appropriate for my QLogic cards. I'm using IBM
LTO4's in a Qualstar XLS library. Yes, I had to modify the stinit.def
file to include LTO4 and I have to modify the /etc/init.d/networker
script (or write one of my own that runs ahead of it) so the stinit
command is run before networker starts controlling the drive.
Because I don't use a fibre switch, but rather connect port to tape
drive, persistent binding doesn't do me any good. It is the port
scanning order that matters (one LUN per port). If I used a fibre
switch so the multiple tape drives were on a single HBA port, then I'd
use persistent binding and have to go through hoops when replacing a
tape drive for whatever reason.

This is a question to those of you using Linux machines as a server or
storage node.
What is the best choice of driver to use when connecting IBM LTO tape
drives to a Linux server? Is it best to install the IBMtape drivers,
or stick with the native st drivers.
How well does persistent binding/naming work with the Linux version of
the IBMtape driver?
If using the native st driver, is it necessary to customise
stinit.def? Does it in fact run stinit at the right time?
What are your experiences with LTO tapes on Linux?
