Problems with multiple harddisks on my Indigo2

Problems with multiple harddisks on my Indigo2

[Klaus Naumann]

Hi all

While trying to build a 2nd harddisk into my Indigo2
I experienced the following problems.
The bus is terminated correctly and with 2 m external
cable to my scsi case it also shouldn't be to long.
When I try to copy data from a harddisk to the other
I get weired I/O erros after some time of heavy I/O.
On the console I get something like:
cp: /mnt/redhat/kernel23/linux/arch/sparc/lib/COPYING.LIB: Input/output error

And dmesg shows:
attempt to access beyond end of device
08:03: rw=0, want=959546428, limit=1888830
attempt to access beyond end of device
08:03: rw=0, want=958585434, limit=1888830
attempt to access beyond end of device
08:03: rw=0, want=959546428, limit=1888830
attempt to access beyond end of device
08:03: rw=0, want=958585434, limit=1888830
attempt to access beyond end of device
08:03: rw=0, want=941858675, limit=1888830


Ususally the system is pretty unstable after these messages.

Also I'm getting a message
sc1,2,0: cmd=0x12 timeout after 2 sec.  Resetting SCSI bus
every time I restart my Indigo2 on the serial console -
does anyone know what that means and if it's a problem ?

Further more it happens that after heavy I/O a simple "sync"
needs more than one minute.

Has anyone seen the same or equal problems in any way
and/ was able to resolve these ?

	TIA, Klaus

I have an SGI Indy, with 2 internal hard disks, a 4GB and a 1GB

I get the same thing!

I started getting this when I added the 2nd HD (1GB).


Bye for Now,

Ian

fwiw, i got this too on my indy when i added a Quantum Empire 1GB.

does (PROM gives me the exact same error message as the one you wrote
above - but prints it twice). If i halt back to PROM then the PROM
does see the second disk. (and only prints that error message once)

my theories are:

1. PROM controller driver is minimal and doesn't init the
controller/disks properly whereas the IRIX driver does. 

2. disk spin up times.. ??

3. Perhaps cause the outboard SCSI port is not terminated. (least not
on my indy)

From cold boot the PROM doesn't recognise the second disk, but IRIX
does (PROM gives me the exact same error message as the one you wrote
above - but prints it twice). If i halt back to PROM then the PROM
does see the second disk. (and only prints that error message once)

All,

Try looking up the jumper'ing information for the drive... There is probably a
delay for spinning the drive up at boot (or some such nonsense).

Ken

checked that.. and it's not it. the jumper isn't set. (i think).

however, this drive used to be in an Alpha, and ARCSBIOS on Alpha had
a problem with not recognising it from cold too, sometimes.

so maybe the drive just doesn't spin up fast enough.

Hello,

Just to let you guys know...

I just tried the 2x HD thing in IRIX (on my Indy), and no problems!  So, it
IS a Linux/MIPS problem!!

I did:  cp -R /usr /hd2

It was going for about 10 mins, before it ran out of disk space (1GB !). No
errors at all   :)


Bye for Now,

Ian

Re: Problems with multiple harddisks on my Indigo2

Good Morning,
The SCSI reset problem occurred on my Indy after I added a Floptical on
ID 2. I am not running Linux on the box at this time. Have upgraded to
6.2 from 5.3 but haven't tried to reinstall the floptical yet. Set
jumpers to Indy specs, so am unsure why. BTW, would the Indy boot from
the floptical for Linux without doing a net boot?
Sincerely,
Dave Keen

I've heard from someone that it is possible - but I'm not
sure - try it ;)

The SCSI port should be terminated with an active terminator on the Indy,
regardless of if you have 1 or 2 drives installed.
