fred :
Help! I'm not yet familiar with all the ins and outs of SCSI drives, and have
the following problem -
I was wondering if it was possible to run a single SCSI hard disk off a SCSI
Which disk drive? Connected internally or externally?
RAID Host adapter? Because I connected an Ultra320 hard disk to a RAID
Which SCSI controller?
controller by itself, and it seems to work for a few weeks without any problem
(except for some message about configuration error 02 on channel B, which I can
just ignore), then one day, the drive just stops working and cannot be checked
Generally error messages should not be ignored.
or verified with any utilities - it just becomes totally unreadable one day, and
Unaccessible or unreadable? How do you launch the
utilities that should check the drive (floppy,
cdrom, another disk drive)? Which utilities? On
what operating system?
the whole drive has to get re-formatted. Then it works fine again for a few weeks.
How do you do this, if the drive can not be read
(accessed)? In another system? Via the controllers
BIOS (then the drive can actually be read/accessed)?
I think this recurring problem might have something to do with the fact I'm
trying to run a single drive on a RAID setup.
Please let me know if this setup I am trying is an impossible configuration, or
should I not be experiencing this phenomena with a single drive setup?
If it's just a case of me having created an unsupported configuration, then
adding a second identical drive will fix it, yes?
If you want a qualified answer you should at least
post info on your:
- Motherboard and BIOS,
- SCSI controller and BIOS/firmware,
- Cable(s)/backplane(s),
- Termination,
- SCSI drives attached internally (and externally),
- Other devices on the system,
- System description (I do like dmesg outputs),
- Boot drive,
- Operating system,
- Detailed problem description (!).
The more detail you give, the better you may
be helped.
A not really helpful answer to your question
may be:
the system I'm writing this message on, has
a non raided scsi device attached to a raid
controller working flawlessly since years.
Much more information (still not really
answering your problem is the dmesg output
of the system, which tells you that it has a
tape drive attached to an Adaptec 3200S raid
controller):
