- Hello,
-
- I'm quite new to using SGIs and I had a couple of questions.
-
- First of all, is it necessary to use hardware links in /dev for newly
- attached disk drives? Coming from a Sun environment, I'm more used to
- mounting the actual devices as file systems instead of things like
- /dev/disk1. I like to see what hardware is being used where, and since
- you're really using the same major and minor device numbers of, say
- /dev/dsk/jag0d1s7, what's the harm?
-
- Secondly, I've been told that the system really doesn't care what SCSI
- device numbers you use on the SCSI chaains, so long as the id isn't 0.
- True? Does the system just recognize what a device is by probing the
- bus or something?
-
- Can I get a machine to run its administrative tools with the
- display on another (part of the faq, perhaps?)? On my SGI server,
- it complains that it "can't access a needed shared library".
- How do I set it up right?
-
- Lastly, how do I create tape drives on a SCSI bus? I would like to
- set up an exabyte 8500C on the system, but how do I go about using the
- compressed and non-compressed modes? I know you use different minor
- numbers on the device to get the different modes, but how do I space
- the numbers to get it right? On a Sun, for example, the base number is
- the tape drive with rewind, and the base number+4 is no rewind, and so on.
- Any suggestions would be appreciated.
-
-
- Thanks for any help you can give.
-
- Jon
